|The student shall be informed of the reasons for preserving food in terms of their quality and safety. The student will acquire an overview of biochemical, microbiological and physico-chemical processes occurring in food matrices. The student will acquire an overview of abiotic and anabiotic preservation methods for extending the shelf life of perishable foods.|
|1. Rationale and specific aspects of food preservation; the importance of preserving of food in terms of food quality and safety.
2. Characteristics of biochemical, microbiological and physicochemical processes, which occur in food matrices; assimilation and dissimilation; intra-molecular respiration; characteristics of saprophytic microorganisms, distribution, behavior and its impact on food matrix.
3. Distribution of preservation methods according to the character of their effect and to their effect on the food matrix.
4. Direct inactivation of microorganisms - factors influencing the direct inactivation of microorganisms during the thermal sterilization.
5. Direct sterilization by heat, high-frequency heating and resistance heating.
6. Direct sterilization using ionizing radiation and chemical sterilization.
7. Direct sterilization by ultrasound, UV radiation and light impulses.
8. Indirect preservation by osmotic pressure, and ultra-high pressure and inert gas.
