Enzymes are used in food production, processing technology and cycles, as well as excipients as an antiseptic. Yeast is also used to produce alcohol. For the correct implementation of the technology, using the example of distilleries in the production of bioethanol or rectified edible alcohol, enzyme preparations are used in the brewing department. Enzyme preparations are dosed with a dosing pump in proportions up to the amount of starch in the batch.
