Abstract:

Antimicrobial activity plays an important role in food preservation in general. Microorganisms are undesirable organisms in food products and therefore we are forced to preserve our food. There are many ways how to inhibit the growth of microorganisms. One of the method is application of compounds with antimicrobial properties which kill or inhibit the growth of microorganisms. Essential oils have been chosen as an agent of antimicrobial activity in this particular diploma thesis. Essential oils are aromatic volatile liquid compounds and they have already been proved as beneficial preservatives. Moreover, essential oils are extracted from plant material and therefore they are positively perceived by modern society in comparison with synthetically produced food additives. Nevertheless, this diploma thesis focuses on preservation in vapor phase which is relatively new method with a huge potential. The main objective of the thesis is to determine antimicrobial activity of certain types of spices in vapor phase that could be potentially used in modified atmosphere packaging.
