Manufacturers make 1 kilogram of cheese that usually contains around 0.0003 grams of rennet. Rennet (4 majors type) An enzyme used to coagulate milk for cheese production. calf rennet 5% of domestic Europea ncheese today microbi al rennet fermentation-produced chymosin or rennin attributed 90% of cheese production in the U.S Produce through fermentation process using genetically modified microorganisms bioengineered to produce bovine chymosin (calf genetic material). vegetable coagulants Whey protein? • History of whey started since 3000 years BC, when Bedoiuns (desert-dweller, nomadic groups) carried milk in bags made out of animals stomach. • The heat in the desert caused acidification and coagulation in milk, resulting in an acid liquid (whey) on top of milk curd sediment (cheese). • Whey is the liquid remaining after the production of cheese or the removal of fat and casein (80% of the protein from milk) • Worldwide production of whey is estimated to be over 100 billions kilograms per year Constituents of whey Whey is a nutritious liquid (water soluble protein) containing mainly β-lactoglobulin , α-lactalbumin Bovine serum albumin & Immunoglobins) and lactose •minor constituentsvitamins and minerals and also enzymes, hormones and growth factors. Infant formula ENZYMES Enzymes are biocatalysts which accelerate the rate of chemical reactions All proteins Present in all living cells Exhibit a high specificity 3,000 different enzymes have been isolated and classified Enzymes in Man The enzymes inside the mouth are contained inside of the saliva. The saliva is mostly water -- about 97 to 99.5 percent -- the rest is made up of enzymes, mucus, antibodies and electrolytes.
