The course is divided into two parts. Principles of Food Preservation focus on the various methods of food preservation. The basic principles are described for each method, the method of storage products and changes that can be expected during storage products are given. Food packaging is focused on describing of the basic functions of food packaging. It describes methods of construction packages for the protection of the packaged product from mechanical changes, changes in moisture, oxidation processes, changes in taste and smell, the effect of temperature, the effects of contamination by micro-organisms, insects and rodents, etc. Attention is also paid to the hygienic aspects of food packaging and to the effect of the packaging systems on the environment

The students will able to:

Describe the changes taking place during production and storage of foods.

Propose the preservation method for particular food product.

Calculate the lethal effect of heating and design its optimization.

Suggest a packaging system for a given food product including specifications functional properties of suitable packaging materials.

Specify the possibility of using a packaging material during food processing.
