Aims of the course:Instruction is focused on technology, in which is exerted the high security microbial stability during processing and effects of fabric components of the food matrix. Discussed will be also pre-harvest and post harvest aspects of maintaining health and quality during storage.
Course contents:
1.Pre-harvest factors, biochemical aspects of maintaining quality during storage and processing. Using antiethylen products for improving the quality of storage of fruits, vegetables and flowers. Influence of microbial stability of raw materials and semi-finished products and the means. (allowance 10/0)
2.Models of gas production in the ambient atmosphere, and methods to minimize them. Modern possibilities to extend the keeping quality of fresh fruits and vegetables, ambient atmospheric models of treatment, agents that affect the physiological response. (allowance 4/0)
3.New variants of antimicrobial preserving techniques for dried materials, materials with added ingredients, materials conventionally sterilized, aseptically packaged foods.Preservation of high-pressure, pulsed electric field (PEF), treatment of intense light flashes. Preservation of food by ionizing radiation. (allowance 10/0)
4.Microbial resistance types of food, and coliform bacteria of the genus Enterobacteriace. Water activity (aw) in food, microbial stability derived from aw. Storage and distribution of food and packaging materials. (allowance 4/0)
5.Postharvest Technology Innovation of the project was funded by OPVK innovation of study programs horticultural disciplines, Reg No. CZ.1.07/2.2.00/28.0220 (allowance 0/0)
