Study of quantity of casein present in milk Rating:
The study of the quantity of casein present in milk is an important aspect of dairy science and technology. Casein is a protein found in milk and is responsible for many of the unique properties of milk, such as its ability to form a gel or clot when mixed with certain enzymes or acids. The quantity of casein in milk can vary depending on factors such as the species of animal, the stage of lactation, and the diet of the animal.
There are several methods that can be used to determine the quantity of casein in milk. One common method is called the Gerber method, which involves precipitating the casein from milk using a strong acid, such as hydrochloric acid. The precipitated casein is then collected and weighed to determine the amount present in the milk sample.
Another method is called the Kjeldahl method, which involves breaking down the protein in milk into its component amino acids and then measuring the total nitrogen content. The quantity of casein can then be calculated based on the known nitrogen content of casein.
The study of the quantity of casein in milk is important for several reasons. In the dairy industry, it is used to determine the quality and value of milk and milk products. For example, milk with a higher casein content may be more suitable for making cheese, while milk with a lower casein content may be more suitable for making butter or cream.
In addition, the quantity of casein in milk can also have an impact on the nutritional value of milk and milk products. Casein is a high-quality protein that is important for human nutrition, and milk with a higher casein content may be more nutrient-dense.
Overall, the study of the quantity of casein in milk is a vital aspect of dairy science and technology, with important implications for the dairy industry and human nutrition.

BHARAT JAIN DEDICATION I DEDICATE THIS PROJECT WORK TO THE LOTUS FEET OF MY FATHER Mr. To differentiate those who take advantage of legal rules from the ones who commit food adulteration is very difficult. The test requires to be done with distilled water as well as with tap water. The general formula of soap is Fatty end water soluble endCH3- CH2 n COONa Soaps are useful for cleaning because soap molecules have both a hydrophilic end, which dissolves in water, as well as a hydrophobic end, which is able to dissolve non polar grease molecules. Appearance of brown precipitate confirmed the presence of glucose in cold drinks.

Then oils are heated, or melted if they are solid at room temperature. On the basis of their molecule size carbohydrates are classified as:Monosaccharide, Disaccharides and Polysaccharides. There are varying levels of trace. Casein is frequently found in otherwise nondairy cheese substitutes to improve consistency especially when melted. Casein is present in milk as calcium caseinate in the form of micelles. Casein is present in milk as calcium caseinate in the form of micelles.

Adulteration of chalk powder, washing soda in sugar Adeulteration of yellow lead salts to turmeric powder Adulteration of red lead salts in chilli powder Adulteration of brick powder in chilli powder Adulteration of dried papaya seeds in pepper To small amount of sugar in a test tube, add a few drops of dil. Average composition of milk from different sources is given below: Source of milk Water % Mineral % Protein % Fats % Carbohydrates % Cow 87. But amount of sucrose varies in each brand of drink. It readily dissolves in dilute acids and alkalies. Chemical Requirements: Five different soap samples, distilled water, tap water. These bacteria convert lactose of milk into lactic acid which is sour in taste. Filter the solution and add 2 drops of KI solution to the filtrate.
As it exists in milk, it is a salt of calcium. So we need simple screening, tests for their detection. The resultant forms a round structure called micelle. Fat along with Caesin was precipitate out. Close the mouth of the test tube and shake vigorously for a minute. But all soaps are not equally effective in their cleaning action.
Chemistry Project to Study the Quantity of Caesin in Milk
Sucrose is one of the most useful disaccharides in our daily life. Adulterants in FoodTfflDRy The increasing number of food producers and the outstanding amount of import foodstuffs enables the producers to mislead and cheat consumers. Theory — Milk contains 3 to 4% casein suspended in water in the colloidal form. Objective: To compare the foaming capacity of various soaps. Aggarwal EXTERNAL EXAMINER REMARKS. The hydrophobic portion made up of a long hydrocarbon chain dissolves dirt and oils, while the ionic end dissolves in water. The change in colour of pH paper was noticed and was compared with standard pH scale.
British terminology, on the other hand, uses the term caseinogen for the uncoagulated protein and casein for coagulated protein. No red colour observed Pure sugar dissolves in water but insoluble impurities do not dissolve. Applied to a soiled surface, soapy water effectively holds particles in colloidal suspension so it can be rinsed off with clean water. It is non-reducing in nature whereas glucose is reducing. I take this opportunity to express my deep sense of gratitude for his invaluable guidance, constant encouragement, constructive comments, sympathetic attitude and immense motivation, which has sustained my efforts at all stages of this project work. OBSERVATION Appearance of oil floating on the surface.

The solutions are then allowed to stand when the foam produced during shaking disappears gradually. Various soap samples are taken separately and their foaming capacity is observed. Wash the beaker 250 ml with the distilled water and dry it. When the acidity in milk is sufficient and temperature is around 36 degree, it forms semi-solid mass, called curd. Not enough alkali and the soap are greasy. Warm the above contents of the beaker to 40 — 45°C on a low flame. The solution was filtered and transferred the precipitates in another beaker.
Average composition of milk from different sources is given below: Source of milk Cow Human Goat Sheep Water % 87. Appearance of yellow coloured precipitate confirmed the presence of alcohol in cold drinks. Its presence is detected by the following test:1. Poonam Taneja , for the help and guidance she provided for completing the investigatory project. ACKNOWLEDGEMENT I wish to express my deep gratitude and sincere thanks to the Principal, Raji Jayaprasad, Aditya Birla public school, Kovaya for her encouragement and for all the facilities that she provided for this project work.
