Food adulteration means anything adding or subtracting with food making it injurious to health. This adulteration may be done intentionally or unintentionally. Intentional adulteration is a criminal act and punishable offense. Or the process of lowering the nutritive value of food either by removing a vital component or by adding substances of inferior quality. Food Safety and Standards Act of India (FSSA) defined “adulterant” as any material which is or could be employed for making the food unsafe or sub-standard or mis-branded or containing extraneous matter”. According to Federal Food, Drug and Cosmetic Act (FFDCA), the primary food safety law administered by the Food and Drug Administration (FDA), food can be declared adulterated if:

1. a substance is added which is injurious to health
2. cheaper or inferior quality item added to food
3. any valuable constituent is extracted from main food article
4. quality of food is below the standards
5. any substance has been added to increase bulk or weight
6. to make it appear more valuable

The proximate system of analysis consists of the analytical determinations of water (moisture), ash, crude fat (ether extract), crude protein and crude fibre. Nitrogen-free extract (NFE), more or less representing sugars and starches, is calculated by difference rather than measured by analysis.

Water

1. Water constitutes about 70 percent of an adult’s body weight and water (moisture) is the predominant constituent in many foods.
2. All foods contain varying amounts of water in the range of 20 to 90%.
3. The hypothalamus is a brain center that controls activities such as maintenance of water balance, regulation of body temperature, and control of appetite.
4. Moisture content of some foods

1. Sample: One or more units selected from a population of units, or a portion of material selected from a larger quantity of material
2. The Standard Operating Procedures (SOPs) should contain full working instructions as well as information on applicability, expected performance, internal quality control (performance verification) requirements and calculation of results. It should also contain information on any hazards arising from the method, from standards or from reagents.
3. Analytical Samples: The quantity of the analytical sample to be used is usually indicated in tests and assays. Unless otherwise specified, the quantity used may deviate by 10% from that stated. All quantitative determinations should be conducted on triplicate test portions and in these cases, the amount actually taken should be accurately weighed or measured and the result of the analysis calculated on this exact quantity. When substances are to be “accurately weighed” in a test or assay, the weighing is to be performed in such manner as to limit the error to ± 0.1% or less. Quantities smaller than 100 mg should be weighed to the nearest 0.1 mg.

Procedure: Measurement of smoke point of given oils: Heat the given oils in a deep frying pan till fumes come out from oil. Record the temperature when the fumes come out and noted it as a ‘smoke point’. Cool the oil by keeping oil pan at room temperature. After cooling repeat the heating of same oils 2nd and 3rd time to measure the smoke point and record the observations

The RTS beverage was prepared by using freshly prepared carrot juice, sour orange juice, water and sugar as per FPO specification.

Yogurt is a fermented milk product that contains the characteristic bacterial cultures such as Lactobacillus bulgaricus and Streptococcus thermophilus. All yogurts must contain at least 8.25% solids not fat.

Pickling is the process of preserving or extending the shelf life of food by either anaerobic fermentation in brine or immersion in vinegar. The pickling procedure typically affects the food’s texture and flavor. The resulting food is called a pickle, or, to prevent ambiguity, prefaced with pickled. Foods that are pickled include vegetables, fruits, meats, fish, dairy and eggs.

Selection fresh fruits/frozen stored fruits/chilled fruits/fruit pulp/sulphited fruit. Wash them to remove the dairt, dust, stems, leaves, stalks, undesirable portions.

Drying is one of the oldest methods of preserving food. It is usually accomplished by the removal of water. Dried foods are preserved for long storage time because the available moisture is very low, so that the micro organisms cannot grow and enzyme activity is controlled. It is done by many methods. 1. Sun drying 2. Using mechanical dryers.

Formulation & method of bread making Baking is an exact science that requires precise measuring and accuracy. Accuracy is crucial in baking because most baked products are made from the same basic ingredients: flour, liquid, fat, sugar, salt etc. the difference between baked products are often the proportion of each ingredients in the formula. If the proportions are off, you will end up with a different product or an unacceptable product.

Sensitivity-Threshold tests Sensitivity tests are conducted to assess the ability of individuals to detect different tastes, odors and feel the presence of specific factors in.

Pure sugar when heated melts at about 160-1800c. at about 2100c sucrose loses water and becomes caramel.
