To analyze milk object To measure the pH of milk and the formation of casein in milk using acid and vinegar. Introduction Milk is a nutritious food. It is an important source of protein, riboflavin, calcium, vitamin B complex and vitamin A. The ingredients of milk will depend on factors such as age, type of cattle, kind of feed, number of milk production. Every year. Milk can be thought of as including three basic ingredients such as water, fat, non-fat solids (NFS) or solid-fat-free (NSF). The fat-free organic matter consists mainly of protein, casein, albumin and globulin, lactose and lactic acid, and citric acid. This experiment examined the change in pH when the acidity of milk changed. Even before it leaves my chest, milk is harmless and contaminated with bacteria even though there are few numbers. Processing and processing activities may introduce more microorganisms. The two main types of bacteria contained in milk are lactic acid and Escherichia coli. Lactic acid is an ordinary bacterium contained in milk and dairy products. Escherichia coli is the main cause of milk rot. Casein can be coagulated with chymosin contained in chymosin (calf's stomach extract). Renin is most effective at body temperature (37 ° C) Reaction is very slow if milk is too cold Renin is altered and invalid if milk is too warm. The mechanism by which chymosin coagulates casein is different from acid precipitation of casein

Precondition: The lowest level of CHEM 101 / L, CHEM 101 is "C-". Core requirements: CHEM 102 L. Continuation of CHEM 101. Introduction of kinetics, gas phase and solution equilibrium, electrochemistry, chemical thermodynamics, radio, organic chemistry, and more familiar descriptive chemistry of metals and nonmetals. In the memorization section, we will solve problems, discuss teaching materials and quizzes. The laboratory section includes the processing speed, the balance of acid base and solubility, the selected reaction of metal and non-metal, and the qualitative elemental analysis experiment. Completion of CHEM 102 / L meets general education, natural sciences including corresponding laboratory requirements. 3 hours of lecture, 1 hour of reading per week, 3 hours of laboratory per week
Master of Science in Food Science and Ph.D. program includes laboratory and advanced research in food preservation, food safety, food processing method, food microbiology and food chemistry analysis. Advanced degree programs are research intensive, reaching the top of the thesis and thesis. Please read the following article and learn about undergraduate course and graduate school graduate certificate and degree program of food science. According to the US Department of Labor Statistics (BLS), food science and technology personnel must have at least one associate degree degree (www.bls.gov). For food processing and agriculture, a bachelor's degree is usually necessary. Graduate degree can lead to vocational supervision of food safety issues and development of new products and processes
Food scientists apply chemical, physical and microbiological principles to food processing, preservation and product development. The Food Science Course provides students the basis of calculus, chemistry, physics, communication, statistics and biology. The course is usually focused on food engineering / processing, food chemistry, food microbiology and food quality. The Fo
