Course content

- The role of microorganisms in food production. Sources of microorganisms in food. - Undesirable microorganisms in food - pathogenic microorganisms and microorganisms that cause food deterioration. - The metabolism of microorganisms in food - alcohol, lactic, propionic and acetic fermentation, metabolism of nitrogenous substances and lipids. Microbial metabolites devaluing food. - Extrinsic and intrinsic factors affecting growth and survival of microorganisms in food. - Additives and their interaction with microorganisms in food. - Inhibitory substances produced by microorganisms important in food industry (bacteriocins, organic acids, etc.) - their applying in food industry. New methods of food preservation. - Microbiology of non-fermented food. - Utilization of microorganisms in fermented food and beverage production. - Lactic acid bacteria - classification, physiology, genetics, importance and utilization in the production of fermented foods of plant and animal origin. - Metabolism of lactic acid bacteria - the utilization of carbohydrates, the conversion of pyruvate, malic-lactic fermentation, acceptors of oxygen and electrons, metabolism of nitrogenous substances and proteolytic system. Effect on sensory properties of foods. - Functional foods in relation to microorganisms. Probiotics, prebiotics and synbiotics. - Direct and indirect detection of microorganisms and their metabolites in food. Cultivation and non-cultivation methods. The use of new detection techniques (molecular biology and immunology, ATP detection, etc.). - Microorganisms that cause alimentary infections and intoxications. Types of toxins and their mechanism of action. - The use of genetically modified microorganisms in food production. Health risks. Detection of genetically modified microorganisms in food.
