Method for producing salt-free compound amino acid powder from combination of sesame seed meal and soybean meal

Abstract

The invention discloses a method for producing salt-free compound amino acid powder from the combination of sesame seed meal and soybean meal as raw materials, which relates to a production method of compound amino acid powder. The method comprises the following steps of: (1) crushing the mixture of the sesame seed meal and the soybean meal, adding water into the powder, adding amylase, alpha-amylase, cellulase and compound protease into the powder respectively, and adding high-temperature resistant brewing high-activity dried yeast into the mixture to perform enzymolysis and fermentation at the same time; (2) after 4 to 7 days of heat-preservation enzymolysis and fermentation, performing filtration for the first time, and adding active carbon of which the weight is 1 to 4 percent of thatof filtrate into the filtrate to perform decolorization for 2 to 4 hours in a boiling state; and (3) performing spray drying on concentrated solution. Compared with an acid hydrolysis method and an alkaline hydrolysis method, the method causes no environmental pollution, and the produced leftovers can also be processed into feeds; the amino acid composition of the product is more reasonable, which can greatly improve the amino acid score of the product; and the soybean meal has a beany flavor, and the sesame seed meal has a sesame flavor, so the sensory score of the amino acid product obtained by compounding the soybean meal and the sesame seed meal is improved.

Description

technical field [0001] The invention relates to a method for producing salt-free compound amino acid powder, in particular to a method for jointly producing salt-free compound amino acid powder by using sesame meal and soybean meal as raw materials. Background technique [0002] Sesame meal is a by-product of sesame seed oil extraction, with an average crude protein content of 42.5%~47.9%, which is a high-quality resource for the preparation of amino acids. On the one hand, compared with silkworm chrysalis and blood meal, the use of sesame meal can greatly reduce the production cost of amino acid powder; on the other hand, sesame meal has high quality and rich content of essential amino acids, such as methionine, cystine and tryptophan The content of methionine and arginine is higher than that of bean cake, cottonseed cake and rapeseed cake, and the content of methionine alone is 40% higher than that of bean cake. The content of other amino acids such as threonine and leucin...
