Annotation -
It introduces the student to the fundamentals of food and biochemical sciences and their interconnections with chemical sciences, biological sciences, some branches of physics, agricultural sciences, food engineering, legislation and economics, and some aspects of medical sciences. In the scope of processing of agricultural raw materials into foodstuffs, the student is introduced to aspects of ongoing microbial, chemical, textural, sensory changes, aspects of food maintenance in relation to food quality and safety, taking into account the requirements of current food legislation both in general and in terms of processing of individual commodities.
