8.1. Fungi useful in food processing

8.1.1. Aspergillus sojae and Aspergillus oryzae

Aspergillus sojae and Aspergillus oryzae (Fig. 198) is a mold species in the genus Aspergillus. Its use was originated in China in the 2nd century AD and spread throughout East Asia where it is used in cooking and as a condiment.

Uses

• It is used to prepare Soy sauce (also called soya sauce) a condiment made from a fermented paste of boiled soybeans, roasted grain and brine,
• In Japan it is used to make the ferment (K?ji) of soy sauce, the mirin and other lacto-fermented condiments like tsukemono. Soy sauce is a condiment produced by fermenting soybeans with Aspergillus sojae, along with water and salt.

Accumulation of nutrient elements in plant tissues indicates the accessibility of the concerned elements from the soil to the plant. Although different plant species and even different varieties of the same species may vary in their nutrient requirements, composition of a part or of the whole plant may well be adopted as a guideline to support the soil-test results for factual assessment of soil’s nutrient supplying power.

Application of ultrasonography has become a routine practice in canine and feline medicine to detect pregnancy, to ascertain foetal wellbeing, to ascertain live/dead status of the foetus, ovarian dynamics, and to diagnose reproductive ailments (uterine, ovarian,) in females. Sonography is also being preferred in males for the diagnosis of diseases of prostate gland, cryptorchid, and testicular diseases.

A. Define / Explain the following

1. Mitosis: The multiplication of a body cell into two daughter cells of equal size and containing the same number of chromosomes as in the parent cell is called mitosis or somatic division.

2. Meiosis: Meiosis occurs only in gonads (in germ mother cells) during the formation of gametes like sperm and ovum. Meiosis is a process by means of which double number or 2N or diploid chromosomes is reduced to its half number or n or haploid. It is also called reduction process.

Today a number of countries have moved away from the inorganic or chemicalised farming to organic farming yet it is not possible for India to depend entirely upon this system of farming due to increase in human population. As total availability of plant nutrients from different organic sources is projected to 7.75 MT by 2025 against the total requirement of 37.50 MT for 1504 million populations, so it means if we depend on organic sources there would be deficiency of about 30 million tonnes of nutrients.

Fruits and vegetables account for nearly 90% of total horticulture production in the country. India is the second largest producer of fruits and vegetables in the world and the leader in several horticultural crops namely Mango, Banana, Papaya, Cashewnut, Arecanut, Potato and Okra. However, the nature of horticultural crops being such that it’s not easy to make assessment of their production. These crops, especially vegetables are grown in small plots, fields or in the backyard of the houses; do not have single harvesting in most of the cases which makes their assessment difficult. Many horticultural crops have multiple pickings in a single season. Similarly many fruit trees are scattered, which do not count for assessment.

India has witnessed increase in horticulture production over the last few years. Significant progress has been made in area expansion resulting in higher production. Over the last decade, the area under horticulture grew by 2.6% per annum and annual production increased by 4.8%. During 2017-18, the production of horticulture crops was 311.71 Million Tonnes from an area of 25.43 Million Hectares. The production of vegetables has increased from 101.2 Million Tonnes to 184.40 Million Tonnes since 2004-05 to 2017-18 and production of fruits has increased from 50.9 Million Tonnes to 97.35 Million Tonnes since 2004-05 to 2017-18.

The major components of the immune system are the lymphocytes which constitute lymphoid system (Figure 2.1).The lymphoid organs are classified into two categories: primary and secondary lymphoid organs.

Plant parasitic nematodes cause serious problems in sustained crop production. For a successful management of nematodes, their morphology, biology and host - parasitic relationship should be thoroughly studied. A thorough study is achieved only when its taxonomical position is known. Thus, in a simple way taxonomy can be defined as the theroretical study of classification of an
organism.

Land, water and weather are natural resources that are critical for survival. Modern agriculture requires precise information on various agro-climatic parameters like soil, crop, climate and water resources for formulating efficient agricultural planning. Out of these, water is considered most scarce input in agriculture because its availability is reducing drastically for agriculture as well as drinking purposes. Besides, declining water tables and deteriorating quality of water resources caused pollution and sewage and effluents have further multiplied the problems.

Bread is considered as one of the oldest processed foods to be known, traditionally prepared using wheat flour and water and baked on hot stones. The process of bread making involves hydration of protein and formation of gluten network ABSTRACT 70 Bakery and Confectionery Technology upon mixing, the evolution of carbon dioxide owing to the action of yeast on sugars and aeration of the mixture by incorporation of the gas followed by coagulation of the dough upon heating it in the oven. 

Weeds can be defined as plants which are undesirable, persistent, damaging and interfere with growth of other crop plants thus affecting agriculture, natural resources and economy of the country. These plants influence the produce of farmers in several ways.

Plant propagation by means of seed is called ________ propagation.

A. Sexual          B. Parthenocarpy

C. Asexual        D. Apomixis

Air or atmosphere constitutes one of the integral components of the environment. Among all the environmental components, the air has the highest fluidity. Therefore, the entry of a foreign substance into the air imparts a quick and severe effect on the health of the organisms. Air in the biosphere has a mixture of various gases in a dynamic proportion which is conducive to maintaining the health and sustenance of all living organisms. An alteration in the composition of the atmosphere beyond a certain limit adversely affects organisms’ health, and might even be of more serious consequences for life.

Air pollution, thus, is defined as the occurrence of undesirable gases (e.g., carbon monoxide, sulfur dioxide, etc.) or particles (e.g., suspended particulate matter) in such concentrations that are deleterious to terrestrial life (vegetation, animals, and human beings) and some physical assets, like buildings, statues, and monuments. Air pollution especially affects the health of human beings living in highly modified (anthropogenic) ecosystems, e.g., cities and industrial areas.

An Entrepreneur is an individual who creates a new business, bearing most of the risks and enjoying most of the rewards. The process of setting up a business is known as entrepreneurship. An Entrepreneur is commonly seen as an innovator, a source of new ideas, goods, services and business procedures. Entrepreneurship plays a key role in any economy by using the skills and initiative necessary to anticipate needs and bringing good new ideas to market.

4.1 Biomass Energy Resource

Among the various methods for producing electricity, biomass is one of the most common. This method uses animal waste, wood pellets, etc. to produce electricity. The use of biomass energy has proven beneficial over time and has the potential to be both reliable and consistent as an alternative energy source.

Organic matter is simply referred to as biomass. Or, to put it another way, biomass is anything living or ever living, including animal waste, crop waste, garden trash, etc. As a result, biomass renewable energy is the energy produced during the use of biomass. Biomass derives and stores its energy from the sun, which is absorbed by plants through a process known as photosynthesis. Plants contain chemical energy that is passed to animals and then eaten by people. Various plant and animal products, including sugarcane, corn crops, wood chips, and even dung, can be utilised. These substances, also referred to as feedstocks, are converted into a biomass fuel.

5.1 Waste Treatment and Disposal

Source reduction and feeding the hungry are significant considerations for decreasing avoidable food waste. However, non-edible wastes like livestock manure, agricultural wastes, and unusable food wastes are also classified as organic wastes. The environment and general public’s health may be seriously endangered by improper treatment of these wastes. Wastes can contaminate surface and ground waterways by runoff or leaching if they contain pathogens, chemicals, antibiotics, and nutrients. The breakdown of organic waste also results in the production of methane. As is well known, methane is a powerful greenhouse gas that captures more heat into the atmosphere than carbon dioxide. It is possible to remove organic waste and turn it into biogas, a sustainable energy source that can be utilised to reduce greenhouse gas emissions and the likelihood of stream pollution. Further emission reductions are made possible by replacing fossil fuels with biogas, sometimes leading to carbon-negative systems.

Abstract

The current photosynthesis of flag leaf is the most crucial source of assimilates that are essential for grain development in wheat. Translocation of these assimilates from the leaf to grain takes place in the form of sucrose. However, environmental cues that influence assimilate balance between the leaf and the developing grain which act as source and sink respectively determine grain yield prospects of wheat. The assimilate translocation system that links source and sink can also play a significant role. Hence, this aspect of assimilate supply has been a focus of research over the past few decades for crop improvement particularly under abiotic stress environment that tend to alter source-sink balance by impairing physiological and developmental processes in plants. Grain growth is mainly triggered when the primary assimilates meet the metabolic needs of the developing grains through the current photosynthesis or through assimilates stored in the form of Non-structural carbohydrates in stem. Hence, the improvement of photosynthetic capacity to synthesize sucrose, its storage remobilization, and utilization becomes imperative under abiotic stresses. Various aspects of Non-structural carbohydrates in wheat stem have been estimated, and efforts have been made to reveal the mechanisms of assimilate partitioning. In this context this chapter discusses strategies to improve grain yield with greater insights into the photosynthetic carbon assimilation, the pathways actively involved in the transport of sucrose from source to sink and their utilization at the sink organ. The information related to assimilate supply to the developing wheat grain under high temperature and drought stress conditions can provide opportunities to translate this knowledge into traits for improvement of climate resilience in wheat.

Introduction

The kidneys play a vital role in maintaining water and electrolyte balance (such as chloride, potassium, calcium, hydrogen, magnesium, and phosphate ions). It also regulates the acid-base balance of the blood, arterial blood pressure, and osmotic pressure of the nd water-soluble waste products, which are removed from the bloodstream by the kidneys and excreted as urine. Normally, the kidneys receive about 22% of the cardiac output. According to Arthur Cushny (1866-1926), there are three steps involved in urine formation in the nephrons: glomerular filtration, tubular reabsorption, and tubular secretion. When the kidneys are injured, their regulatory activities are disrupted, resulting in a change in the quality and quantity of urine. Urine is composed of the following components:

This is the reason why a urine analysis is a common test to evaluate the pathophysiology of the urinary system in general and the kidneys in particular, as well as to aid in the differential diagnosis of certain diseases.

Biopesticides are pesticides that are produced naturally by plants, animals, microbes, and other minerals. These represent less of a harm to humans and the environment than chemical insecticides. Nanotechnology is a rapidly developing scientific topic that has numerous uses in numerous industries, including agriculture. The transport of plant hormones, seed germination, water management, transfer of target genes, nano barcoding, nano sensors, and controlled release of agrichemicals are now being investigated as applications for nanotechnology in agriculture (Worrall et al. 2018).

The shaper machine is a reciprocating type of machine (that is, the machine that converts the rotatory motion into the linear motion) in which the tool reciprocates with the forward and backward stroke removing the metal form of metal chips and turning the Metal workpiece into the desired shape.

Duck production has an immense role in improving the socio-economical status of rural farmers. In India, duck farming occupies an important place next to chicken farming. Duck contributes about 7-10% of the total poultry population of the world. Ducks are water fowl, hence, they need a semi-aquatic lifestyle. They need a pond, lake, river, canal or any such type of water bodies for their survival. Thus, they are mainly concentrated in West Bengal, Assam, Andhra Pradesh, Orissa, Kerala, Tripura, Tamil Nadu, Bihar, Jammu & Kashmir and Manipur. Ducks are reared for both eggs and meat purposes. Unfortunately, duck farming is not done in an organized way in our country.

India is a “Winter / Summer Home” for most of the Siberian birds such as Siberian Cranes, Greater Flamingo and Demoiselle Crane, also numerous species of birds from other regions of the world. These beautiful birds migrate to India every year during the winter and summer season for food, breeding and nesting. The migratory birds mainly arriving from Siberia and South East Asia move to the different wetland spots of the national parks/ wildlife sanctuaries etc. in India and are also seen in parts of the lakes and settling down in shallow or fresh water ponds. 

3.1. Introduction

Paper and paper-based packaging is the traditional form of packaging used for various food products due to its various advantageous characteristics. It is less expensive, flexible, lightweight, durable, recyclable and available in various shapes, sizes and colour to meet customer needs. Hence it occupies a vast market in food packaging from primary (i.e., packaging which is first used after manufacture) to secondary (i.e. processing aids of primary packages) packaging and the production of paper has doubled in the last three decades. In the year 2020, china was the leading producer for paper and paper based packaging followed by USA and Japan (Figure 1).

2.1 Simple Random Sampling

The simplest and common most method of sampling is simple random sampling. In this procedure, the sample is drawn unit by unit with equal probability of selection for each unit at each draw. It is sometimes referred to as unrestricted random sampling.

2.1.1 Definition

“A sampling procedure which gives equal chance to all possible samples each of size n which can be drawn from a population of size N, is called simple random sampling.”

Urban agriculture involves various aspects of growing plants and taking up other activities. Those include terrace gardening, vertical gardening, green walls, hydroponics, etc. Although several other types of garden present in urban areas, the gardens suitable for residental premises are discussed in chapter.

Terrace Garden

Terrace garden is generally established on a terrace or rooftop of a house having limited land space for gardening. This type of gardening is gaining momentum in the cities. These gardens can be created on different buildings like residential flats, individual houses, public buildings, commercial establishments and factories. The growth and development of the plants give immense pleasure to the garden owner. Plucking a fresh cucumber on the terrace provides a different pleasure, which is beyond the physical value of the fruit. The experience of consuming a fresh watermelon from own garden has unique satisfaction. As there is minimum or no space for growing plants in urban areas, the terrace can be transformed to an attractive garden. Irrespective of size of the terrace, it can be converted to a beautiful garden with proper planning. There are multiple ways for revamping the terrace depending on available time and resources.

Vegetables belonging to the family Brassicaceae (Syn: Cruciferae) are known as Cole crops. These are the most widely grown vegetables in temperate and sub-tropical zones. The word ‘Cole’ comes from abbreviation of word ‘caulis’ meaning stem. Cole crops are a group of highly differentiated plants originated from a wild plant Brassica oleracea var. oleracea (=B. sylvestris L.) commonly known as “Wild cliff cabbage” or “colewort”, through mutation, human selection or adaptation. Cole crops include cabbage, cauliflower, knol khol, Brussels sprouts, Chinese cabbage, sprouting broccoli, kale etc. of which cabbage and cauliflower are the most popular and widely grown.

Mediterranean region is the centre of origin of Cole crops. From there, it spread to Europe and other temperate and sub-tropical regions. Cabbage, knol khol and curly kale were the first known cultivated types. Cauliflower became widely known in the 18^th century and Brussels sprouts in 19^th century. In the thirties of 20^th century, sprouting broccoli started cultivation particularly in the USA.

Linnaeus in 1753 included all forms of Cole crops in one species, Brassica oleracea. Later the works of many, including Neuwhof (1969) resulted in putting them into different forms as given below:

B. oleracea var. capitata L. - Cabbage

As per United States Department of Agriculture (USDA), organic farming is defined as a system which avoids or largely excludes the use of synthetic inputs (such as fertilizers, pesticides, hormones, feed additives etc.) to a maximum extent and feasible rely upon crop rotations, crop residues, animal manure, off farm organic waste, mineral grade rock additives and biological system of nutrient mobilization and plant protection. FAO suggested that organic agriculture is a unique production management system which promotes and entrance agro-ecosystem health, including biodiversity, biological cycles and soil biological activity and this is accomplished by using on-farm agronomic, biological and mechanical methods is exclusion of all synthetic off-farm inputs.

At the outset, I need to state that I am not a horticultural specialist and whatever horticulture knowledge have, is gained on the job and I am a plant genetic resources specialist with an interest in biodiversity and have worked across Asia. Today we will be mainly talking about tropical fruits and, in particular, tropical fruit tree genetic resources. If you look at tree fruits as a group, it includes a large number of species, unlike in field crops, e.g., rice, wheat, maize, etc., where just a few species are involved in each crop. Here we are talking about a group of species under each fruit tree. While talking about them, certain generalizations have to be made. Also, there are many unexploited species which are waiting to be discovered for human usage and exploitation, and there is hardly any genetic information available about them.

It encompasses a diverse range of nanomaterials, including nanoparticles, nanotubes, and nanowires, each exhibiting unique properties that enable enhanced performance in sensing applications. The integration of nanomaterials into sensing platforms has demonstrated remarkable progress in various fields, such as environmental monitoring, healthcare diagnostics & security applications.

Agroforestry is a land use system that involves two or more plant species at least one of which must be a woody perennial. When perennial woody and herbaceous components are grown together on the same piece of land their performance would largely depend on their ability to share various growth resources in a given environmental situation. Due to difference in growth pattern and resource requirement of the components in agroforestry situation, a close interactive relation is obvious. Thus, careful management practices for the components are required to establish a successful agroforestry system. The characteristics of the trees and crops, and their interactions, can be modified with good management practices in order to take advantage of the positive characteristics and minimize the effects of the negative ones. Effective and efficient agroforestry management may be divided into two groups; tree management and agricultural crop management.

Trees have been used in cropping systems since the beginning of agriculture. Throughout the world, at one period or another in its history, it has been the practice to cultivate tree species and agricultural crops in intimate combination. In the tropics, human beings underwent a transition from hunting/gathering to the use of domesticated plants and livestock. As a part of the process, they cut down trees, cleared the debris by burning and sowed crops in the ashenriched soil. It was the ‘slash-and-burn’ agriculture, a primary forerunner of the present-day agroforestry and a practice that might have originated in the Neolithic period, around 7000 BC. There are innumerable examples of traditional land-use practices involving combined production of trees and agricultural species on the same piece of land in many parts of the world. Trees were an integral part of these farming systems and they were deliberately retained on farmlands to support agriculture. These practices are now known as agroforestry. However, the ultimate objective of these practices was not tree production but food production.

3.1 Overview of pyrolysis technology

Pyrolysis is a process derived from the Ancient Greek words “pyro” meaning f ire and “lysis” meaning separation, which means separating by using heat or fire. This is a thermochemical conversion process that converts biomass into a useful intermediate liquid product, which can be further transformed into a hydrocarbon biofuel, oxygenated fuel additive, or substitute for petrochemicals. Pyrolysis is similar or overlapping with other thermochemical processes such as cracking, carbonization, torrefaction, destructive distillation, dry distillation, and thermolysis. It is not related to gasification, which involves chemical reactions with a gasification medium.

Even though the great Indian author Surpala mentioned in his epic ‘Vriksha ayurveda’ (Science of Tree growing) about the value of incorporation of earthworms in soil for better propagation of pomegranate plants in 10th century AD, but Sir Charles Darwin’s recognition to earthworms as ‘Farmer’s friends’ in 1837 in fact, inspired researchers throughout the world to study the role of earthworms in soil ecosystem.

Earthworms are defined as soft, bilaterally symmetrical, tubular segmented worms which contain clitella gland, prostomium lobe in front of mouth and anus at the posterior end. The entire body is divided externally into a series of distinct segments. Scientifically these terrestrial worms are classified under phylum ‘Annelida’ due to presence of annuli or ring segments and class ‘Oligochaeta’ due to presence of few setae or hair like structure on all segments except the first and last ones.

Definition of Disaster

A disaster can be defined as a sudden or catastrophic event that causes significant damage, destruction, and disruption to human life, property, or the environment. Disasters can be natural, such as earthquakes, hurricanes, floods, wildfires, or they can be human-made, including industrial accidents, terrorist attacks, or technological failures.

Disasters often result in the loss of lives, injuries, displacement of people, infrastructure damage, and the interruption of essential services like electricity, water, and communication systems. They can have long-lasting impacts on communities, economies, and the environment.

Governments, organizations, and communities implement disaster preparedness, response, and recovery strategies to mitigate the effects of disasters, protect lives and property, and facilitate the rebuilding and restoration of affected areas.
