Course Description

COURSE CONTENT

Composition, characteristics, nutritive value and differences of the main milk types. Methods and efficiency of mechanical, thermal and membrane processing of milk during production of pasteurised and sterile milk and milk powder. Milk fermentation by mesophilic, thermophilic, therapeutic and combined cultures of bacteria, and by yeasts as moulds as well. Impact of technological processes on characteristics of fermented milks. The role of probiotics and prebiotics. Nutritive value and therapeutic effects of fermented milks. Cheese classification. Methods of milk coagulation. The role of dairy cultures and other additives into cheese milk. Technological processes in production of different cheese types. Conditions and nurturing of cheese during ripening. Biochemical processes involved in primary and secondary stages of ripening, the ways of protecting cheese and possible defects. Composition and nutritive value of cheese and whey, possibilities of whey processing. Production of butter and ice cream.
