If you are going to buy and sell these bottles even semi-seriously the price of annual dues for the Association is well worth the money. Lactose It is the principal and typical carbohydrate of milk known as milk sugar. Glucose galactose and other sugars such as oligosaccharides are also present in traces. Lactose exists in true solution in milk. It is a disaccharide composed of two molecules of monosacharides; glucose and galactose. Lactose is readily fermented by the lactic acid fermenting bacteria producing lactic acid and has significance in milk and milk products. It exists in two isomeric forms designated as α and β forms of which the β form is more soluble than the alpha form in water. Lactose content of cow milk is 4.9 percent. The lactose content of milk is inversely proportional to the ash content of the milk.
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.
Udder infection promotes an increased level of chloride in the milk and depresses the secretion of lactose. Proteins Milk protein is a rich source of essential amino acids. Whey proteins are proteins that are passed along with the whey portion after the coagulation of milk. They contain 51% essential amino acids when compared to 45% in casein. The sulphur containing amino acids which are considered essential and important are found in higher concentration in whey protein than in casein. Usually the quality of egg proteins are regarded as very high. But the net protein utilization biological value and the protein efficiency ratio of milk protein come neck in neck with the quality of egg protein. Lactalbumin a whey protein whose biological value net protein utilization and protein efficiency ratio is considered superior when compared to the major milk protein casein. Normally double the quantum of vegetable protein is required to meet the daily requirement of essential amino acids when compared to that obtained from the milk proteins.
