Department of Quality Features and Microbial Products
Head: Alexandra Proskova



abou us:

Department of Quality Features and Microbial Products examines the problems of microorganism cultivation with the aim of optimizing the generation of new products including biomass and the issue of the utilization of food processing byproducts, and fermentation and separation technologies. It participates on the development of analytical methods for proving food authenticity. The utilization of various byproducts and wastes within the agriculture and food complex, the cultivation of microorganisms in order to create new products, as well as the development and implementation of analytical methods for the proof of food authenticity belong to the broad issue areas of interest. As for the matter of the cultivation of microorganisms, the goal consists in optimizing the production of fermentation products including the biomass and, connected with that, in the development of new-type food complements (e.g. Diastabil). This department also examines the possibilities of utilizing wastes and byproducts produced by food processing and agriculture. Important materials are involved, e.g. the chitin-glucan complex from mould biomass and the otherwise unused byproducts from mushroom cultivation, whey as a dairy byproduct for the manufacture of ethanol, yeast biomass, food complements, fermented beverages or edible packaging, furthermore offal from poultry and fish processing plants for the production of gelatine, or waste fats from rendering plants for the production of biofuels. Attention is also paid to the utilization of the interesting components contained in plant materials like vegetables, cereals and non-traditional berries. This department also participates in the development of analytical methods for the proof of food authenticity using various methods, primarily liquid and gas chromatography. It has prepared standard operational procedures (SOP) for various methods proving the adulteration of pure instant coffee, sunflower, soybean and olive oils, pure butter, honey, dark and milk chocolates, or the addition of plant components to meat products and the irradiation of high-fat food products like poultry or cheeses. It also studies the implementation of immunochemical methods for the authenticity verification e.g. of meat products and for detecting allergens in soybeans and fruit or vegetable juices. It also watches the incidence and causes of cow’s milk protein allergy in children including the application of hypoallergenic toddler formulas.

we offer the following services:

  • processing of microbial biomass to fluid-dried or spray-dried food and feed additives

  • provision of know-how regarding the biosynthesis of microbial biomass enriched with biologically bound trace elements

  • provision of pure cultures listed in the catalogue of the collection of microorganisms

  • maintenance of active industrial inoculum for production of feed or food yeast

  • development of methods for preparative isolation of proteins from a supplied sample of raw material

  • development of HPLC/FPLC methods for separation for mixed proteins

  • proofs of adulteration of pure instant coffee, sunflower, soybean and olive oils, pure butter and honey

  • detection of thermal treatment of milk declared as pasteurised or UHT

  • determination of monosaccharides, oligosaccharides, fatty acids and sterols in foods and raw materials
