Course abstract

The students can get knowledge in chemical composition, physical properties and criteria of estimation of milk, meat and fish quality in the subject “Basics of Food Technology”. Also students obtain basic skills in principle of production of food products and learn about physical, biochemical and microbiological processes for acquiring of food products quality during making of food products. In laboratory works students can get skills for quality control of food products.

Learning outcomes and their assessment

After completing of course student will have:
• knowledge about the quality criteria’s of raw materials, its quality assurance and the role for production of food products;
• skills about the causal relationships of food products defects relating with raw materials composition and quality, applied technological parameters, additives, and inadequate storage conditions for raw materials and products;
• competence in criteria’s of raw materials and their assurance for production of safety and wholesome food products.
