Yeasts are microorganisms that are widely used in industry. Since ancient times they are applying in traditional production of wine, beer and bakery products. In addition to biotechnology, former are used in the food industry as a food supplement, usually as baker's yeast or dried biomass. The term yeast involves the active yeast biomass used for leavening in baking. Baker's yeast is produced in sugar beet molasses and cane sugar or the mixture of the two molasses. Yeast grown in bioreactors with regulation of all parameters of cultivation. After the cultivation, the yeast is extracted by separation, whereby the so-called yeast suspension (liquid yeast). Vacuum filters allocate part of the water form yeast suspension and the product removed from the filter is called yeast cake. This biomass is pressed, formed and packed, and it represents another form of yeast called fresh pressed yeast which is cooled in the coolers, after which is transported to the market. Fragmentation of yeast cakes and drying in a stream of conditioned air produces the active dry yeast. The former is usually packaged under vacuum and does not require refrigeration during storage and transport, which is a third form of baker's yeast.
