Introduction

Cashew is an important horticultural crop. It has gained status of commercial crop from that of a forest component through technological advancements with respect to propagation, production and management. This has been possible as a result of increasing demand for raw cashew nuts and enhanced interest for its commercialization. The demand is mainly due to its good quality protein, unsaturated free fatty acids, rich blend of minerals and water-soluble vitamins, which altogether contribute an excellent dietary supplement. It is being cultivated by as many as 28 countries in Asia, Africa and Latin America

The term Anesthesia means loss of sensation.

GENERAL ANESTHESIA

In the technique of anesthesia, a drug is capable of causing loss of sensation together with loss of consciousness, sufficient to allow a surgical operation to be carried out.

Routes of General Anesthesia (G.A.)
Inhalation

Ether, Nitrous oxide, Halothane, Chloroform etc.

Combination of an opioid (butorphanol/buprenorphine) and an alpha-2 agonist (xylazine/dexmedetomidine) along with an NMDA antagonist and benzodiazepine (tiletamine-zolazepam or ketamine-midazolam) will make up a balanced anaesthetic cocktail. Examples for balanced anaesthetic cocktails are xylazine/dexmedetomidine-butorphanol-midazolam-ketamine and butorphanol/ buprenorphine-tiletamine zolazepam-dexmedetomidine/xylazine (Ko, 2013; Cagle et al., 2017; Sooryadas et al., 2019; Verma et al., 2020). The latter ones are costly due to the tiletamine-zolazepam and dexmedetomidine in them, while the former ones are cost effective alternatives.
Xylazine/Dexmedetomidine-Butorphanol-Midazolam-Ketamine (XBMK/DBMK) Anaesthetic Cocktail
The preparation can be made by drawing 0.1 ml/kg of ketamine (50 mg/ml presentation) along with 0.1 to 0.2 ml/kg of the xylazine-butorphanol-midazolam (XBM) or dexmedetomidine-butorphanol-midazolam (DBM) sedative cocktail in a single syringe. For intravenous administration, 0.1 ml/kg each of ketamine and the sedative cocktail is to be chosen, while for intramuscular administration 0.1 ml/kg of ketamine and 0.2 ml/kg of the sedative cocktail is preferred. The volume of the cocktail that needs to be administered intramuscularly will be larger by 0.1 ml/kg when compared to the tiletamine-zolazepam based anaesthetic cocktails. Anticholinergic premedication is preferred prior to administration of anaesthetic cocktail containing xylazine (Nesgash et al., 2016), particularly if given intravenously. The XBMK/DBMK anaesthetic cocktails will induce anaesthesia in a few minutes, which last for 20 to 40 minutes (Ko, 2013; Verma et al., 2019; Verma et al., 2020). Intravenous administration of the anaesthetic cocktail provides shorter duration of surgical plane of anaesthesia. When administered as said above, the combination provides xylazine @ 0.2 - 0.4 mg/kg or dexmedetomidine @ 2.5 - 5 mcg/kg, butorphanol @ 0.1 - 0.2 mg/kg, midazolam @ 0.125 - 0.25 mg/kg and ketamine @ 5 mg/kg body weight which is as per their recommended doses when given in combination (Verma et al., 2019; Verma et al., 2020).

Analytical testing provides objective evidence of the composition, safety, physical structure, and sensory quality of ice cream. This chapter introduces the major analytical approaches used in industrial ice cream manufacturing, including chemical, physical, microbiological, and sensory evaluation. Important parameters such as fat, milk solids-not-fat, protein, sugars, ash, acidity, pH, overrun, meltdown, fat destabilization, texture, and product weight are discussed. The chapter explains how different tests support routine quality control, product development, troubleshooting, research, regulatory compliance, and shelf-life studies. It emphasizes that no single analytical parameter can define overall quality. Effective product evaluation requires integrated interpretation of chemical, physical, sensory, microbiological, and storage data.

Sample Preparation

 Cheese sample is prepared by passing through 8 mesh sieve three times or

grate sample and mix thoroughly or grind to a uniform mass in a glass pestle

and mortar. Keep the sample in an airtight container until the time of analysis.

 1 Determination of Moisture Content in Cheese

 Introduction

The moisture content of cheese is defined as the loss in mass, expressed as a

percentage by mass when the product is heated in a hot air oven at 102 ± 2°C

to constant mass.

Sample Preparation

Sample should be taken at six or more points on the top of the surface by means of a tubular trier of sufficient length to extend to the bottom of the barrel. Remove this cores and transfer to clean, dry, air tight container and seal immediately.

Before opening sample for analysis, make homogenous either by shaking or by alternately rolling and inverting container. If lump are present, sift sample through No 20 sieve, rubbing material through sieve and tapping vigorously, if necessary.

Avoid sampling on rainy day or when humidity is high, so as to reduce moisture absorption from air.

1 Determination of Moisture Content by Moisture Balance Introduction

In this procedure, infra-red radiation is used to accomplish rapid drying. The tester has a sensitive torsion balance which permits rapid determination directly from the balance scale, eliminating the need for computing or calculation to obtain results. This method is useful for the in-process determination of moisture because the results may be obtained in minutes.

Sample Preparation

a) Plain products: Sample should be softened at room temperature. Since the melted fat tends to separate and rise to the surface, it is not advisable to soften the sample by heating on a water bath or oven or flame. Mix thoroughly by stirring with spoon or eggbeater or by pouring back and forth between beakers.

b) Ice-cream containing Fruits and Nuts: Fill one third part of the cup with ice cream sample. Melt the product at room temperature and mix until insoluble particles are finely divided (about 3-5 minutes for fruit pieces and upto 7 minutes for nut pieces). Otherwise, the product may be ground in a porcelain or glass pestle and mortar. Don’t let temperature exceed 25oC at any time during softening and mixing steps. If fat separation occurs, discard sample otherwise immediately pour mixture into wide jar and cap tightly. If allowed to stand, shake vigorously before taking sample for analysis.

Groundnut is one of the main oilseed crop of India.Unlike many oilseeds, Groundnut can be consumed directly in various farms and hence now it is also being considered a supplementary food crops. In india groundnut is grown in an area of about 6.5 hectares with a production of  about 7 million tones of pods per annum (2007). It is one of the few crops that can be cultivated even on marginal lands under low input conditions. Unfortunately average productivity of groundnut in india is quite low (1000kg) compared to (USA-3000 kg/ha, China- 2600 kg/ha, Argentina-2100 kg/ha  and  Indonesia-1550 kg/ha).

Sampling of Milk for Analysis

A careful and accurate sampling is of utmost importance for the analysis of milk. It is a fundamental principle of sampling that the quantities withdrawn, must be proportional to the quantities contained in the respective containers and uniform throughout in its composition.Thorough mixing of milk must first be ensured either by stirring or by shaking gently. If milk from an individual animal is to be sampled, the sample should be taken from the middle of vessel containing the whole amount of milk. If the sample bottles have been standing for sometime, resulting in the separation of fat in the cream layer or lumps of fat appear, the bottles may be heated in a water bath upto 40°C to melt the fat before mixing. Milk should not be shaken very violently under any circumstance as it may result in an uneven distribution of fat.

1 Analysis of Chemical Composition of Milk

 1.1 Determination of Acidity of Milk

 Introduction

The acidity of milk can be determined by titrating the milk against standard sodium hydroxide solution using an indicator like phenolphthalein and is expressed in the terms of lactic acid. Though natural acidity in milk is due to its constituents such as casein, albumin, citrates, phosphates and carbon dioxide but it is customary to express in terms of lactic acid. As one gram equivalent weight of an alkali neutralizes one gram equivalent weight of an acid, the volume of standard alkali required to neutralize lactic acid of fixed volume of milk gives percent acidity of milk according to the reaction.

Where Y is the average yield of a crop in a sequence over a period of years “n” and S is the standard deviation of yield over a period of years, Y max is the maximum yield of a crop in a certain year.

Example 1. Six crop sequences were evaluated in simple randomized block design replicated four times at Durgapura. The sequences tried are pearl millet-wheat, cluster bean-wheat, pearl milletmustard, cluster beanbarley, cowpea-mustard and pearl millet-Chickpea under irrigated conditions.

True/False

Q.1.    According to Prof. RA Fisher “ANOVA” is the separation of variance assignable to one group of causes from the variance assignable to other group of causes.
Q.2.    The basic purpose of ANOVA technique is to test the equality (homogeneity) of several population means from the same 
experiment.

Analytical methods development and validation play important roles in the discovery, development, and manufacture of pharmaceuticals.

Pharmaceutical products formulated with more than one drug, typically referred to as combination products, are intended to meet previously unmet patients need by combining the therapeutic effects of two or more drugs in one product. These combination products can present daunting challenges to the analytical chemist responsible for the development and validation of analytical methods. This presentation will discuss the development and validation of analytical method (Spectrophotometric, High performance liquid chromatography (HPLC), & High performance thin layer chromatography (HPTLC)) for drug products containing more than one active ingredient. The official test methods that result from these processes are used by quality control laboratories to ensure the identity, purity, potency, and performance of drug products.

Analyzing feeds for nutrient content is essential for proper balancing of livestock rations. This is especially essential for those feeds that have undergone the fermentation process. Silage samples should be analysed for dry matter, protein fractions (degradable and undegradable protein, soluble protein, and heat damaged protein), ADF, NDF, mineral content and energy. In addition to these components, lactic, acetic, and butyric and propionic acids, pH, ammonia nitrogen, ethanol, and yeast and mold counts are also quantified.

The safety of the food supply suitably remains a high main concern for industry stakeholders, regulatory agencies and patrons. With the surfacing of new safety challenges and issues, companies are establishing and upgrading programs to reduce risk factors. These programs are constantly monitored for reliability, repeatability, reproducibility and effectiveness. Due to the health and safety risks posed by chemical, microbiological and environmental contaminants, analytical methods are progressively more becoming a pride and joy of food safety programs. Innovative analytical approaches are being developed in response to budding food safety issues. To monitor for known issues only the established and officially approved methods are used often. Oftentimes, new analytical methods are developed, improved or modified quickly in response to issues, such as melamine contamination, which are unforeseen. In such instances, accurate data derived from sound, validated analytical methods are required to facilitate industry stakeholders and regulators to make sound methodical decisions.

Through research, industry has improved a host of analytical methods in recent years, resulting in higher sensitivity and accuracy for difficult-to-detect contaminants, detection of contaminants in new matrix classes for grades. These advances have been made in the face of changing set of laws, more painstaking method-validation standards and end user demands for safe, quality products. Further to this, this spirit of innovation will continue to be fundamental in industry’s efforts to ensure the safety of the comprehensive food chain.

Bacteria from the genus Anaplasma belong to the Procaryota kingdom, the family Anaplasmataceae. Anaplasma belong to obligate intracellular microorganisms, Gram-negative bacteria, living in the blood cells of mammals. Vertebrates can be their reservoir, i.e. an environment where the pathogen can live and proliferate for many years. However, in many cases bacteria from the genus Anaplasma cause diseases in domestic animals and people.
Taxonomical Position of Bacteria from the Genus Anaplasma
The genera Anaplasma, Ehrlichia, Neorickettsia and Wolbachia include obligate intracellular bacteria, parasitizing in the vacuoles of cells in eukarytic hosts. Animal pathogens were attributed to the genus Anaplasma, such as A. centrale, A. marginale, A. platys, A. ovis and A. bovis, and also the aetiological factor of human anaplasmosis, A. phagocytophilum.
Anaplasma marginale
A. marginale are obligate intracellular bacteria parasitizing in erythrocytes of higher vertebrates, mostly ruminants.
Anaplasma Centrale
A. centrale is a parasite in the erythrocytes of ruminants, mainly cattle. As opposed to A. marginale, it creates concentrations in the central part of the cell. A. centrale is less pathogenic to cattle than A. marginale but, most importantly, occasionally gives resistance against the latter. Hence it is used for the preparation of live vaccine strains, assuring immunological protection against bovine anaplasmosis.
Anaplasma Bovis
A. bovis is a bacterium detected mainly in cattle, but also observed in small mammals which are probably a reservoir of this bacterium. It occurs in monocytes, and the disease it causes is called monocytic anaplasmosis. The symptoms of the disease are most visible in calves, but also in adult animals; symptoms include weakening of the body, marked reduction in weight, elevated temperature, enlargement of prescapular lymph nodes, paling of the mucous membranes, and in many cases an elevated amount of secreted mucus.
