Milk fat varies in amount and composition according to the breed species feed and lactation time of which feed being a major factor. Fat is distributed in globules as triglycerides (98-99 %) fat globule membrane in combination with phoshpholipids and lipoprotein (0.2 to 1.0 %) and also as free fatty acids cholesterol and phospholipids in the serum. Phospholipids These contain phosphorus in their molecules in addition to the fatty acids and glycerol; they also contain a nitrogenous base. Principally milk phospholipids are the Lecithin Cephalin and Sphingomyelin. Though fat-soluble they are hydrophilic and imbibe large quantity of water and swell. They are used as antioxidants for fat rich dairy products. Vitamins Various vitamins present in milk are as follows.
Do not let the fact that a bottle is from a state that is known as a diary state dissuade you from buying it. Many of the bottles from these states are rare and command high prices. Bottles with more than one color will usually bring higher prices. Bottles with attractive graphics on their reverse side will often bring higher prices things such as babies; war related themes patriotic themes and herds of cows are just a few things to be on the lookout for. A word of caution In the last several years reproductions of some milk bottles have begun to appear more and more. Fortunately the vast majority of reproductions are of other types of milk bottles but there are reproductions of 1 quart Pyro-Glaze milk bottle as well.
Casein May be defined as the major protein which is precipitated at pH 4.6 and is exclusive to milk. It is present in spherical bodies as micelles which vary in size with negative surface charge. The caseins of milk may be sub-divided into five main classes αs1 αs2 β gamma and k-caseins. In milk casein is present in combination with calcium in the form of calcium caseinate or more precisely calcium hyhdrogen caseinate. Whey proteins Are those in the whey fraction after the precipitation of casein at pH 4.6. These are the alpha-lactalbumin beta-lactoglobulin immunoglobulins lactoferrin transferrin proteose-peptone fractions etc. Most of these are globular proteins subject to heat denaturation. α-lactalbumin exists in variants A and B forms and is susceptible to denaturation by unfolding of the tertiary structure. β-lactoglobulin is identical to blood globulin and insoluble in water and is responsible for the transfer of antibodies.
