The course summarizes the physiological, enzymatic, chemical and microbiological changes taking place in foods, and explain the basic principles of food preservation in the context of classification methods, i.e. - abiosis and anabiosis, and defines new trends. This course allows students to combine the information obtained from the previous study to evaluate the relationships especially aimed at identifying causes of changes or defects and to predict behaviour of food at different storage conditions or processing. Completion of the course, students will apply with greater understanding principles of HACCP and procedures based on risk analysis.

Division into 4 modules: 1) P1: Principles of food preservation (factors affecting unwanted food changes, explanation of principles of preservation based on properties of microorganisms, chemical, physical and enzymatic changes, traditional methods of preserving foods). 2) P1: Advances and trends in the field, advantages and limitations of new methods and approaches (e.g. hurdle theory, active packaging systems, mild physical methods of food processing, bacteriocins). 3) W1: Practical tasks to predict the changes in food under different processing and / or storage conditions, and to propose the optimization and corrective measures in production and distribution chain. It includes the implementation of selected physico-chemical, chemical and microbiological analyses of foods (in the case of packaged foods also inner atmosphere analysis) using modern analytical techniques and instruments. 4) W2: Independent project elaborated with respect to the dissertation theme Last update: Čížková Helena (04.06.2018)

Students will be able to:
To predict the behavior of food at different processing conditions and storage. To optimize the production process in terms of increasing the sensorial and nutritional value and maintaining food safety. To identify the causes of changes or defects food during production and storage. Last update: Čížková Helena (04.06.2018)
