Case Study

The constituents of draw that are most important in feed preparation are enzymes, vitamins, hues, salts, sugar, spicy, and proteins.

Enzymes. The enzymes of cows draw are reported as follows by Rogers; proteinases, lactase, diastase, lipase, salolase, catalase, peroxidase, and aldehydrase. Rogers states that the proteolytic enzyme, galactase, brings about slow decomposition of milk proteins into peptones, amino acids, and ammonia.

Vitamins. All the vitamins recognized at the present cartridge holder are contained in milk. Some are present in comparatively large and others in smaller amounts.

Pigments. The appearance of milk is white. This is due to light rays reflected by the colloidally dispersed constituents of the milk, the calcium caseinate, and calcium phosphate.

Milk contains two classes of yellow or orange tree paints. The water-soluble pigment, which imparts a yellow color with a squirt fluorescence to the whey of milk, was formerly called lactochrome. A name recently suggested for this pigment is lactoflavin. It is regarded as one flavin of a specific group, collectively to be called lyochromes. It is possible that lacto-flavin is composed of more than one pigment. Rogers says lactoflavin forms compounds with saccharides, proteins, and purines (uric acid).



These compounds mayhap either occur naturally in milk or readily form during isolations, thus accounting for the several lactoflavins obscure from milk. It is probable that the pigment lactoflavin is one of the five fractions of vitamin G (B2). Milk is relatively rich in this vitamin.

A fat-soluble pigment, carotene, implant in the fat gives the milk a more or less yellow tinge, which is more pronounced as the fat particles become more concentrated and form cream. The group of pigments called caroti-noids, which take carotene, xanthophyll, and related pigments, has been described in the chapter on fruits and vegetables. The chief pigment of butter fat is the carotene, but little xanthophyll being...If you loss to get a full essay, order it on our website: Orderessay
