Turmeric saponin compound enzyme reagent, preparation method thereof and method of utilizing same to prepare turmeric saponin

Abstract

The invention discloses a turmeric saponin compound enzyme reagent, a preparation method thereof and a method of utilizing the same to prepare turmeric saponin. The turmeric saponin compound enzyme reagent comprises, by weight, 25-35% of neutral pectin lyase raw material, 15-35% of cellulase, 25-35% of wide-temperature-range amylase, 5-10% of glycosidase and 1-3% of notatin. Pectic substance, xylan, glucosan and heteropolysaccharide which are high in acid consumption are directly hydrolyzed through the turmeric saponin compound enzyme reagent, their hydrolysates are taken as nutritional components of microorganisms in the process of fermentation to be utilized fully, and fermentation efficiency is improved effectively; consumption of hydrochloric acid can be directly saved due to absence of above substances in the process of saponin extraction.

Description

technical field [0001] The invention relates to the field of turmeric saponin preparation, in particular to a turmeric saponin compound enzyme reagent, a preparation method thereof and a method for preparing turmeric saponin by using the compound enzyme reagent. Background technique [0002] At present, the vast majority of turmeric saponin production enterprises in my country use the traditional process of "crushing turmeric raw materials-natural fermentation-acidolysis-filtration-washing-drying-gasoline extraction-crystallization-saponin" to produce saponin. A large amount of acid liquid will be produced in the process, which is difficult to recycle. Most enterprises discharge it directly, causing serious environmental pollution. As the country puts forward higher requirements for energy conservation and environmental protection, traditional high-emission and high-pollution saponin enterprises urgently need to reform and transform their production methods. In recent years,...

Problems solved by technology

[0004] The purpose of the present invention is aimed at the disadvantages of biological and chemical means such as uncontrollable natural fermentation, acid hydrolysis, and mechanically broken yam cells in the current large-scale industrial production, and utilizes an enzymatic reaction method to promote the decomposition of some starchy polysaccharides and non-starch polysaccharides in the yellow ginger raw material. Hydrolyze to obtain sugars that are beneficial to the fermentation process and improve the level of biological fermentation; effectively reduce the residue of soluble polysaccharides and monosaccharides, thereby reducing the COD in wastewater; Link key to fully release the active ingredients and increase the yield
