Abstract

In the present study, a novel work on comparison of physico-chemical characterization and bacterial diversity of wheat straw compost and vermicomposting has been initiated in the tropical region. Wheat straw compost shows lesser pH, EC, TDS, Organic Carbon, Total Nitrogen and Total Phosphorus than vermicompost whereas there was an increase in Total Nitrogen, Total Phosphorus and Electrical Conductivity and a drop in the pH, TDS and Organic Carbon of the vermicompost as the composting progressed from 0, 3, 10, 17, 24 and 31 days. Strains of Bacillus spp. and Thermoactinomycetes were screened from the wheat straw compost, which are ecologically important and have commercial potential for enzyme production. These strains were able to degrade cellulose, hemicellulose and lignin and exhibited cellulase activity. Enterobacter aerogenes, Micrococcus luteus and E.coli were isolated from the gut of Eudrilis eugeniae which help in the transformation of biodegradable waste materials into valuable compost.

Abstract

Noodles are widely consumed throughout the world and their global consumption is second only to bread. In the study, response of reducing agents (cysteine hydrochloride and sodium metabisulphite) and oxidizing agents (potassium bromate and benzoyl peroxide) at 10 and 20 ppm levels on the farinographic and amylographic curve characteristics as well as on the noodle making properties of durum and commercial wheat semolina were investigated according to the AACC (1990) procedure. The farinographic curve characteristics revealed that water absorption was enhanced with increasing levels of reducing agents but decreased with addition of oxidizing agents. However there was no significant change in Dough Development Time in case of durum semolina on addition of reducing agents, but commercial semolina recorded significant changes at 20 ppm level of reducing agent. The best reducing agent for durum and commercial semolina was thus sodium metabisulphite and cysteine hydrochloride respectively. Addition of oxidizing agent potassium bromate at 20 ppm level enhanced stability and was thus chosen as the best oxidizing agent for durum semolina and benzoyl peroxide for commercial semolina. Addition of reducing and oxidizing agents improved yield, appearance, elasticity and extensibility characteristics of instant fresh noodles. The best levels were used in the preparation of noodles on the Italian extruder (NAMAD).

Abstract

Demand for starch is increasing day by day and is met by restricted range of crops. In recent years, substantial progress has been made in obtaining starch from non-conventional sources such as sweet potato, buckwheat, sago, water chestnut, which can be used as a substitute for conventional sources. So it is necessary to search for other underutilized and nonconventional sources of starch to meet the increased demand. Typha angustifolia, an aquatic weed containing appreciable amount of starch in its rhizome and roots, can be used for starch isolation to make its use in food and non-food derivatives. In many parts of the world, starch-rich roots of Typha angustifolia are eaten raw or boiled or dried roots are pulverized into a powder, and then, used as a thickener in soups or added to cereal flours to make biscuits and bread.

Abstract

Prebiotics are the non-digestible food ingredients that beneficially affect the host by selectively stimulating the growth and/or activity of one or limited number of bacteria in the colon. These are heat resistant components which remain intact during the baking process; this allows prebiotics to be incorporated into every day food choices. Consumption of non-digestible ingredients allows the growth ofbio cultures by reaching the intestine unaffected by the digestion process resulting in improvement of digestive health. Prebiotics reach the intestine in an unaltered form and shows the prebiotic effect when there is an increase in the activity of healthy bacteria in the human intestine. The prebiotics stimulate the growth of healthy bacteria such as bifidobacteria and lactobacilli in the gut and increase resistance to invading pathogens. Functional foods increase consumer choice by adding prebiotics to every day food items such as cereals, biscuits, breads, table spreads, drinks, and yoghurts. By continuing to eat and drink common foods, but choosing functional alternatives (such as bread containing prebiotics) dietary requirements can be met, without significant changes to foodpreferences. Some common example of cereal based products containing prebiotics are oat-based prebiotic drink, Breakstone's and Knudsen live active cottage cheese, prebiotic yogurt- Attune and Muller vitality, multi-fruit drink enrich and flavoured water enrich, prebiotic flavoured water, prebiotic capsules, dried fruit bars, prebiotic powder- Biocare fructo-oligosaccharides, Newtree purplaisir chocolate spread. The claims are constipation relief, suppression of diarrhea and reduction of the risks of osteoporosis, atherosclerotic cardiovascular disease associated with dyslipidemia and insulin resistance, obesity and possibly Type-2 diabetes. At present, claims about reduction of disease risk are only tentative and further research is needed.

Abstract

The amaranth as a pseudocereal has shown its role in the development and diversification of agricultural products and food which is a priority trend for world agriculture. The amaranth has excellent nutrient profile and technological advantage in various food formulations in comparison to other conventional cereals. Recently, current interest in amaranth also resides in the fact that it has a great amount of genetic diversity, phenotypic plasticity and is extremely adaptable to adverse growing conditions, resists heat and drought, has no major disease problem. This crop is among the easiest of plants to grow in agriculturally marginal lands in hilly area. Moreover, these contain significant amount of bioactive components such as phytosterols, squalene and polyphenols along with good amount of micronutrients such as minerals and vitamins. Amaranth consumption has been shown to improve plasma lipid profile in animals. Methanolic extracts of amaranth have demonstrated anti-hyperlipidemic,anti-diarrheic, anti-fungal and anti-malarial properties. Specific polyphenols such as rutin, isoquercetin and nicotiflorin and phenolic acids and amides with antioxidant activity have been found in amaranth seeds. In addition to above, amaranth, seeds are gluten free and thus they are currently emerging as healthy alternatives to gluten containing grains in gluten free diet for celiac people.

Abstract

The aim of this work was to reduce the natural fermentation period of ‘idli’ from the conventional 14 hr to10 hr by adding underutilized okara for the preparation of ‘idli’. Black gram was partially substituted with soy residue okara in the ratio of (1:1). After 14 hr of natural fermentation, the pH and total acidity of control ‘idli’ batter was 4.55 and 0.68% and that of okara fortified ‘idli’ batter was 4.57 and 0.56%, respectively. The amount of CO₂ released by the control and okara fortified batter was 12.5% and 22.5% respectively. The viable count of yeast and mold, lactics and mesophilic bacteria in control and okara batter increased with time reaching 8.4 and 9.6, 8.2 and 7.5, and 8.6 and 9.2 log10 cfu/g, respectively at the end of 10 hr of natural fermentation. Okara fortified ‘idli’ was soft and spongy compared to control ‘idli’.

Abstract

The concern of consumers for convenience and healthy foods involves many parameters like functional and nutraceutical properties, ease to prepare, good quality, economics as well as good nutritional profile of the food. This trend of convenience has been increasing in today's world because of the societal changes like the aging of population, the increasing entry of women into the labor force, the change to a multi-cultured society and the increasing polarization between poor and rich. Value addition to the traditional sources is a medium to bring variety products into the market. Cereal starches possess a wide application in the food industry as an additive but the native starch is not widely used in food industry due to its poor functional properties. Pregelatinized starches and flours have become important in processed foods because the functional properties of the starches and flours are improved over the native starches and cereal flours. Modification is a process which alters the structure of the starch in the wheat endosperm by affecting the hydrogen bonds in a controllable manner. Modification of starch and flours is generally done by several methods such as chemical degradation, physical alteration or enzymatic transformation. The primary objective of modification is to reduce the hot viscosity of the starch paste so that higher concentrations of starch can be dispersed without excessive thickening. The pregelatinized flours offer a tremendous number of functional benefits to variety of foods such as bakeries, snacks, beverages as well as nutritional foods. The various functional benefits of pre-gelatinized starch/flour as an additive are classified as fat replacer, texture improver, stabilizer, emulsifier, thickening agent and for freeze-thaw stability. Keywords: Pregelatinization, modification, functionality, cereal flour.

Abstract

The present study was conducted to develop ready to eat extruded snack food based on germinated flour of wheat, Bengal gram and green gram. A Central Composite Rotatable Design (CCRD) for five variables at five levels was used for experimental combinations and optimization of the process parameters. Experimental design with green gram flour (5 to 20%) and bengal gram flour (1535%) in wheat flour, moisture content (14-18%), screw speed (200-300 rpm) and barrel temperature (126-134°C) as independent variables having 32 different combinations of snack formulations that were studied using response surface methodology to investigate the effect of these variables on product responses (Lateral expansion, bulk density, Water absorption index, water solubility index and sensory characteristics). Sensory analysis was carried out of all extrudates for texture, color and overall acceptability. Multiple regression equations were obtained to describe the effects of each variable on product responses. The optimum operating conditions for development of germinated wheat, green gram and Bengal gram flour extrudate were 132°C of barrel temperature, 275 rpm of screw speed, 17 % offeed moisture, 6.5% of green gram flour and 23.1% of Bengal gram flour. The responses predicted by the software for these optimum process conditions resulted lateral expansion of 169.59%, bulk density, 0.263g/cm³; water solubility index, 19.08; water absoption index, 13.88g/g; and overall acceptability value of 7.38.

Abstract

Sedentary lifestyle coupled with excess calorie intake is partially responsible for increased incidence of lifestyle related diseases like coronary heart disease, obesity, diabetes, cancer and hypertension. Non-nutritive sweeteners can offer consumers a way to enjoy the sweet taste with little or no energy. Further, functional beverages are the drinks which are altered in such a way to provide specific health benefits and disease preventing properties beyond general nutrition. In the present paper, authors have summarized various research works on development of different low calorie functional fruit and vegetable products by replacing sugar with non-nutritive sweeteners like saccharin, cyclamate, sorbitol and stevioside at different levels of sweetness (equivalent used to sucrose). The cyclamate sweetened spiced plum squash at 50 per cent sweetness proportion gave higher taste scores in comparison to saccharin sweetened beverage. In case of sorbitol sweetened beverages, with the increase in the proportion of sorbitol sweetness, the organoleptic score for colour, body and flavour increased compared to saccharin and cyclamate sweetened products. Whereas, the stevia sweetened beverages indicated highest sensory acceptability at 75% stevioside sweetness level. Further, sorbitol sweetened health products were found to have similar calculated energy value as that of sucrose sweetened products (100%), but sorbitol is absorbed slowly and does not raise the insulin levels. The development efforts had successfully reduced calorie value of plum squash up to 42% with cyclamate at 50% sweetness level. The calorie value of the sorbitol and stevioside sweetened products has been reduced by 70% and 60% per serving at 100% and 75% sweetness level, respectively. The developed products were found to have strong antimicrobial activity against E. coli as well as high antioxidant potential. Overall, it was concluded that, the developed products had better taste, palatability and storage stability beside reduced energy value, hence their availability in the market will definitely benefit the at risk group i.e. diabetics, obese and health conscious people.

Abstract

Consumer now-a-days relies on manufacturing and processing standards, particularly to know what ingredients are present, due to dietary, nutritional requirements, or medical conditions (e.g., diabetes orallergies). Modified PCR and combination of PCR with other analytical tools have been successfully used for analysis of various parameters related to functional foods such as detection and quantification of beneficial as well as food borne pathogenic microorganisms, food allergens, raw material source, bioactive compounds, genetically modified foods. Multiplex PCR method has been found to be an efficient tool for simple, rapid, and reliable identification of Lactobacillus and Bifidobacterium in probiotic products. Food allergens like gluten, peanut, hazelnut etc. could be easily detected in foods using PCR, even if present in small quantities. BOX-PCR and PCR-DGGE analysis have been used for identification of bacterial diversity of a naturally fermented functional food (Enzyme). HPLC combined with real time -PCR were successfully used to quantify and analyse compounds of secondary metabolites like phenylpropanoid amides, which represent an important class of nutraceutical having strong antioxidant and chemotherapeutic effects in various transgenic tomato tissues. Detection of active compounds in natural plant products were successfully achieved using PCR techniques. In general PCR have gained more importance as it has high sensitivity, improved precision, wide dynamic range for quantification, genotype based and is quick method of detection and quality control of foods than traditional culture based methods.

Abstract

Nanotechnology deals with understanding and control of matter at 1-100 nm dimensions. Nano-sized materials have been part of everyday life in the form of biological entities and processes. Many of the structural building elements in foods are colloids in nature and are built up as a result of self assembly of nano-sized molecules in particles or at interfaces. The most important food raw materials-proteins, starches and fats undergo structural changes at the nanometer and micrometer scales during normal food processing. Unique phenomena occurring at this length scale are being exploited for novel food applications. Functional foods are products, in food or drink form, which influence specific functions in the body and thereby offer benefits for health, well-being, or performance beyond their regular nutritional value. Nanotechnology promises to provide means of altering and manipulating food products to efficiently deliver nutrients like proteins and antioxidants for precisely targeted nutritional and health benefits. Nanotechnology applications for functional food ingredients and additives offer range of benefits to the consumer in terms of innovative, tasteful and healthy food products. Nanoencapsulation systems aid smart protection and delivery of bioactives so as to ensure their stability, taste, colour, safety and bioavailability. The advent of nanotechnology has opened up innovations in food packaging with improved stability and barrier properties. However, need exists to develop regulatory systems for managing any risks associated with functional nanofoods and the use of nanotechnologies in the food industry.

Abstract

Tremendous changes in lifestyle, eating habits and shifting rural habitations are causing an irreversible change that is leading to manifold multiplication of health problems and these health issues have attracted the attention of every segment of the society in the recent past. Today foods are not intended to only satisfy hunger and to provide necessary nutrients for humans but also to prevent nutrition-related diseases and improve physical and mental well-being of the consumers. Due to increasing control over nutrition and health, consumers are becoming more proactive towards their health. In this regard, functional foods play an outstanding role and they are gaining public acceptance and there is great scope for value-added as well as health promoting food products in developing countries. Various terms have used for functional foods throughout the world such as designer foods, medicinal foods, nutraceuticals, therapeutic foods, superfoods, foodiceuticals, and medifoods. People are interested in foods which boost immune system, reduce the risk of diseases and improve health. The increasing demand of such foods can be explained by the increasing cost of healthcare, the steady increase in life expectancy, and the desire of older people for improved quality of their later years. Typically, a food marketed as functional contains added, technologically developed ingredients with a specific health benefit. These range of products cannot be truly classified as ‘food’ and a new hybrid term between nutrients and pharmaceuticals, ‘nutraceuticals’, has been coined to designate them. The development of functional foods involves the application of various food processing techniques such as microencapsulation of functional ingredients for controlled release, nanotechnology for the development of nanostructured (or nanotextured) food ingredients and delivery systems for nutrients and supplements etc. Inclusion of probiotic bacteria and probiotic supplements in various food systems has also become very popular and this is becoming a very vital sector in functional food market. Systematic RandD efforts are, therefore, required to develop health promoting foods for all segments of the society at affordable cost. Prior to promoting the developed health foods, it is of utmost importance to conduct clinical trials to ascertain safety and efficacy, and also establish appropriate regulatory framework for their distribution to masses. All these issues have been discussed in this paper and recommendations were drawn to formulate future research.

Abstract

Egg is a nutrient dense food, containing high quality proteins and a wide range of vitamins, minerals, trace elements, PUFA, MUFA etc. Whole egg slices were prepared by boiling in water technique for a predetermined time i.e. 15 min. The egg slices were prepared with spice extract at different levels of 2%, 5%, 7% and 10%, out of which 5% was found acceptable by sensory evaluation. The egg slices with 5% spice extract were then subjected to frying in different oils such as mustard oil, rice bran oil, sunflower oil and soya bean oil. Among all of the fried egg slices and control (without any spice extract and frying), on sensory evaluation, fried egg slices with mustard oil was most preferred. Texture analysis results shows that hardness was increased on frying and highest in fried egg slices with rice bran oil. Also the values for other TPA component viz. adhesiveness, cohesiveness, gumminess and chewiness were increased on frying as compared with control. Among the fried egg slices, highest values for adhesiveness, cohesiveness, gumminess was observed in egg slices with rice bran oil. However, chewiness of fried egg slices with sunflower oil was highest. It can be concluded from present study that the egg slices fried in mustard oil was organoleptically acceptable with good textural properties.

Abstract

This review assesses the nutritional attributes of Amaranth grains and its utilization as food and as formulated foods. Amaranth is a pseudo-cereal and one of the most ancient cultural food plants with excellent source of superior quality protein (rich source of lysine) which is deficient in wheat and other cereals. Amino acid composition of amaranth protein is close to ideal and, as a result, has high food value. Amaranth grain is loaded with phytochemicals including phenolic acids, tannins, anthocyanins, and phytosterols. Amaranth is potentially a good dietary source of the pro-vitamin A carotenoid (f-carotene), antioxidants (nutraceuticals) and canthaxanthin (which has also been reported to be an antitumor agent) and lutein, which is reported to slow down the development of age-related eye diseases. There are also some anti-nutritional factors (Phytic acid, Tannin and Trypsin inhibitor etc.) that may be reduced by certain processing treatments. Several epidemiological studies show Amaranth grains are helpful in reducing several kinds of chronic diseases like cancers, cardiovascular diseases, type II diabetes and various gastrointestinal disorders. Grain amaranth has been tested and recognised by many authorities as a gluten-free foodstuff appropriate for incorporation into the diet for celiac disease patients. Amaranth grain or young leaves could completely or partially substitute common ingredients, so the crop could be potentially exploited as an ingredient in foodformulation in form of flour, flakes, sprouts, grain undergoing fermentation, popping, malting, extrusion cooking, nixtimisation, and special compounds isolation. The interest in this crop is developing due to its several advantageous properties. The nutritionists find that the grain has higher nutritional value than conventional cereals.

Abstract

The cereal grains are grown around the world, the most common is wheat, which accounts for one third of the total grain crop worldwide. In addition to providing energy, whole grains contain several key nutrients, including fibers, lipids, B vitamins and minerals as well as other beneficial components such as phenolic acids, flavonoids, lignans and phytosterols. Several of these components function as antioxidants. While multiple studies have been conducted to analyze antioxidants in different grains. In wheat and other grains, naturally occurring phytonutrients with antioxidant activity include phenolic acids, flavonoids, coumarins, polyphenols, phytates, terpenes, carotenoids, tocopherols and tocotrienols. Potential roles of the naturally occurring antioxidants in grains include free radical scavenger, reducing agent, complexation of prooxidant metals, quenchers of singlet-oxygen molecules and antioxidant defense enzyme system activators for biological systems. Wheat grain contains several components that have potential antioxidant activity and thus may have a protective role in human health. Traditional wheat-based breakfast foods include hot and cold ready-to-eat (RTE) cereals, as well as a variety of yeast-leavened and chemically leavened bakery products. Increasing baking time and temperature increases antioxidant activity in the bread crust and lowers antioxidant activity in the bread crumb portion. Wheat and wheat based products, particularly partial and 100% whole grain products have been shown to provide a variety of beneficial components including fiber, vitamins, minerals and other phytonutrients with antioxidant activity. Scientific evidence indicates that consumption of three or more ounce equivalents of whole grain foods per day may reduce the risk of coronary heart disease, type 2 diabetes and certain cancers and help with weight management.

Abstract

Re-constituted rice-premixes made by extrusion, has been successfully formulated for the fortification of market rice with vitamin A (retinyl palmitate and betacarotene) and iron. The statistics of vitamin A deficiency (VAD) and Iron deficiency anaemia (IDA) are alarming in the developing world, particularly in India. In fact, India is second largest producer as well as consumer of rice in the world, so fortification of rice with vitamin A and iron seems to be a successful solution to reduce the VAD and IDA in India. In order to design the final formulation, eight formulations containing target micronutrient profile were tested for vitamin A (both retinyl palmitate and beta-carotene) and iron retention for a period of six months under ambient (24-26 ⁰C) and elevated temperature (40 ⁰C) conditions. Nonsignificant iron loss was observed during six months of storage time under both ambient and elevated conditions. The higher retention of retinyl palmitate and beta-carotene was observed in formulation 5 and 8 respectively. In F5, the retention of retinyl palmitate was 73% and 66% and in F8, retention of beta carotene was 70% and 63% under ambient and elevated temperature conditions respectively after six months of storage. Substituting the original, vegetable shortening with palm shortening resulted in increased retention of retinyl palmitate and beta carotene in formulation 5 and 8. Thus, increased antioxidant effect of natural antioxidants in palm shortenings contributed to stability of micronutrients.

Abstract

Nutraceuticals have potential to be used as food supplement, preventive medicine and the growing evidence points in the direction that certain foods fight and or prevent against diseases. The development of next generation nutraceutical “super foods” or products consist of value-addition in the traditional natural diets.The word Nutraceuticals combine ‘nutrition’ and ‘pharmaceuticals’ to mean that they can be used as preventive drugs or food supplements. The increase in knowledge about the immune response unveils the fact that besides immunological disorders and infections the outcome of many other diseases like diabetes, hypercholesterolemia, rheumatoid arthritis, etc. can be modified by modulating Immune response. Hence, the efficient immunomodulators can be employed to prevent or cure the diseases as immunotherapeutic agents. The most acceptable alternative therapeutic agents are the edible sources. Hence the researchers shifted towards formation of nutraceuticals or foods acting as medicine, a concept which was given by Hippocrates long back.

Abstract

The gut microbiota, microbe population living in the human large intestine is generally associated with various metabolic functions and it influences health and well-being. Taking into account the major role gut microbiota play in the normal functioning of the body and the different functions it accomplishes, experts nowadays consider it as an “organ”. However, it is an “acquired” organ, as babies are born sterile; that is, intestine colonisation starts right after birth and evolves as we grow. Each of us has a unique microbiota, as the fingerprints, it always fullfils the same physiological functions and they have a direct impact on our health. Gut microbiota consists of a complex of microorganism species that live in the digestive tracts of animals and is the largest reservoir of microorganisms mutual to humans. Gut microorganisms benefit the host by gleaning the energy from thefermentation of undigested carbohydrates and the subsequent absorption of short-chain fatty acids. The most important of these fatty acids are butyrates, metabolised by the colonic epithelium; propionates by the liver; and acetates by the muscle tissue. The human body carries about 100 trillion microorganisms in its intestines, a number ten times greater than the total number of human cells in the body Guarner and Malagelada, 2003). Gut microbiota, particularly the probiotics, have beneficial effects on gastroenteritis resistance, blood lipids, antitumor properties, lactose tolerance and gastrointestinal immunity. Probiotics have role in reducing the risk of rotavirus-induced diarrhea and colon cancer. The survivability of any probiotic bacteria till a longer time in the gut can be enhanced by the supplementation of prebiotics. Prebiotics are non-digestible food ingredients that benefit the host by selectively stimulating the growth or activity of one or a limited number of bacteria in the colon. There are so many prebiotics which stimulate the growth and survivability of probiotic bacteria such as fructo-oligosaccharide (FOS), inulin, galacto-oligosaccharide (GOS), polydextrose (PDX), acacia gum (GUM), lactulose (LOS), lactitol etc. Many research studies have been done on above mentioned prebiotics. Mostly inulin-type fructans have been used as functional food ingredients. The prebiotics are known for reduction of disease risk such as constipation relief, suppression of diarrhea and reduction of the risks of osteoporosis, atherosclerotic cardiovascular disease associated with dyslipidemia and insulin resistance, obesity and possibly type-2 diabetes. Probiotics are beneficial microbes that confer a realistic health benefit on the host, which in combination with prebiotics, (indigestible dietary fibre/carbohydrate), also confer a health benefit on the host via products resulting from anaerobic fermentation. The combination of probiotics and prebiotics in a synbiotic might improve the survival of the bacteria crossing the upper part of the gastrointestinal tract, thereby enhancing their effects in the large bowel and immune-modulatory ability.

Abstract

The concept of functional foods has received significant media attention and, as a result, interest has focused on the need for research into the non- nutrient constituents of food plants. This has enabled market penetration of functional foods containing increased amounts of bioactive food compounds or physiologically active nutrients and non-nutrients within food that impart proven health benefits. Functional foods can take many forms. Some may be conventional foods with bioactive components that can now be identified and linked to positive health outcomes. Some may be fortified or enhanced foods, specifically created to reduce disease risk for a certain group of people. Numerous observational studies have shown that omega-3 fatty acids enriched diets are associated with a reduction of cardiovascular mortality, heart attack and sudden death. In several studies, a higher fish intake has been associated with decreased incidence of coronary artery disease (CAD) and cardiovascular mortality. A trial revealed that fish oil supplementation of 130 mg/kg of body weight each day decreased the number of stiff joints, duration of morning stiffness, pain and global arthritis activity. Many supplements contain active ingredients that have strong biological effects in the body. The bioavailability of nutrients within a given food is governed by the composition and microstructure of the food, commonly referred to as the food matrix. More specifically, numerous studies investigating the development of functional foods have shown that the interactions between nutrients and non-nutrients within the food matrix can be synergistic, additive, or neutralizing in nature. The preventive and curative effects of the functional foods on health concludes it to be integral components of established public health programs to reduce the risk of specific diseases.
