The principal constituents of milk are water, fat, proteins, lactose milk sugar and minerals salts. Milk also contains trace amounts of other substances such as pigments, enzymes, vitamins, phospholipids substances with fatlike properties , and gases. The residue left when water and gases are removed is called the dry matter DM or total solids content of the milk. Milk is a very complex product. In order to describe the various constituents of milk and how they are affected by the various stages of treatment in the dairy, it is necessary to resort to chemical terminology.

Great resourcefor Dairy scienceBy M. BryantI have a background in chemistry andhave taken a good amount of biochemistry courses.


Therefore only limit values can be stated for the variations. The soluble amino end contains amino acids t. One way this is measured in food is by water activity which is very important in the shelf life of many foods during processing? Back Your first visit.

It is not metabolized by oral bacteria and hence is not cariogenic. Genetic variants of a protein differ from each other only by a few amino acids. The most important and most widely used method of indicating their specific characteristics is to measure the iodine value IV of the fat. A long hydrocarbon chain repels water and makes the amino acid less soluble or compatible with water.

Maillard reactions are initiated by heat treatment and continue during storage of the product. Supplementation of cream cheese with essentials oil improved the oxidative stability? Salts of Milk. When the lumen is full, the myoepithelial cells surrounding each alveolus contract under the influence of oxytocin and the.

Correlations between growth-rate of the suckling of various species and the percentage of total calories from protein in the milk. The data in Table3. The resulting monoglycerides, free fatty acids and some glycerol are transported across the basal cell membrane and re-incorporated into triglycerides inside the mammary cell Fig. Some hydrophobic constituents of the membrane probably diffuse into the core of the globules while components of the plasma may adsorb at the outer surface.

  1. Preservation of sensory and chemical properties in flavoured cheese prepared with cream cheese base using oregano and rosemary essential oils. Vitamins A and D are soluble in fat, while the others are soluble in water, which can then be used to calculate the iodine value. It is therefore common practice to determine the refractive index of fat. Factors such as heat cause unfolding of the whey proteins and increased interaction between the proteins and alcohol may dehydrate the particles.

  2. Chemistry (Jenness and Paton, ), Dairy Chemistry and Physics (Walstra chemistry and biochemistry of milk and milk products and encourage you.

  3. The metallic oxidation off-flavour is more common in winter than in summer. The rate of destabilization is influenced by the fat content, P, years ago, liquid:solid fat ratio. Sheep and goats were domesticated early during the Agricultural Revolution. Cayot.
