Milk Composition.
Proteins.
Слайд 3Where?
The major milk proteins are synthesized in the mammary epithelial cells
and are only produced by the mammary gland.
But the immunoglobulin and serum albumin in milk are not synthesized by the epithelial cells.
They are absorbed from the blood
Слайд 4High quality protein in cow milk is one of the key
reasons why milk is such an important human food.
Caseins have an appropriate amino acid composition that is important for growth and development of the nursing young.
But sometimes most of the whey protein is not digested in the gut. This leads to an allergy to milk proteins
Слайд 5Output casein
Casein may come out of solution, forming the gelatinous material
of the curd.
This is part of the basis for formation of all non-fluid milk products like cheese.
Слайд 6Centrifugation of the skim milk in an ultracentrifuge results in pelleting
of the casein
produced whey
Слайд 7Casein molecules can also be separated from the whey by precipitation
of the casein with acid or by disrupting the micellar structure with a proteolytic enzyme
Form the different types of cheese
Specific bacterial cultures are used to establish the conditions for lowered pH
