The invention discloses a production process for preparing a quick-acting
nitrogen source based on efficient enzymolysis of vegetable
protein. The production process comprises the following production steps: 1, preparing a quick-acting
nitrogen source; feeding the materials; a proper amount of peeled
soybean meal and clear water are prepared, the ratio of the
soybean meal to the clear water is 10: 7, the
soybean meal is put into a digester,
tap water is added while the soybean
meal is put into the digester, after the materials are put into the digester and before steam is introduced for heating, the digester rotates for 15 minutes to enable the soybean
meal and the water to be fully and evenly mixed, then steam is introduced for heating and cooking, and the
moisture of the cooked materials is controlled within the range of 48%-52%. The invention relates to the technical field of biological culture media, in particular to a production process for preparing a quick-acting
nitrogen source based on efficient enzymolysis of vegetable
protein, which comprises the following steps: selecting soybean
meal with stable quality and lower cost as a
protein raw material, and carrying out
solid-state
fermentation, liquid-state enzymolysis, separation and concentration /
drying to obtain a product of which the dry AN is greater than or equal to 5%. The method realizes preparation of an industrial quick-acting
nitrogen source product considering three items, belongs to an emerging product in the market, and has a huge market prospect.
