Problems solved by technology

[0004] At present, solid-state fermentation brewing companies often discard the by-product yellow water directly, which causes waste of resources and brings pressure on environmental protection, and there are few reports on the application and development of a large number of short-chain fatty acids in yellow water. At the same time, the current SCFAs glyceride products are mostly chemical raw materials. Synthetic, and the purity is low, which limits the application in health and other fields

Abstract

The invention discloses a preparation method of short-chain fatty glyceride. The method comprises the following steps: (1) carrying out centrifugal treatment on a solid-state fermentation byproduct yellow water; (2) filtering a supernatant obtained by the centrifugation; (3) carrying out reduced pressure distillation and concentration on a filtrate obtained by the filtration, adding an acidic water treatment agent, and carrying out reduced pressure distillation and extraction again to obtain a distillate, namely an enriched short-chain fatty acid aqueous solution; (4) rectifying the short-chain fatty acid aqueous solution to obtain a purified short-chain fatty acid solution; (5) carrying out an esterification reaction on the short-chain fatty acid solution and natural glycerol under the action of monascus esterifying enzyme to obtain a short-chain fatty glyceride mixed solution; and (6) refining the short-chain fatty glyceride mixed solution through molecular distillation to obtain theproduct. The method has advantages of advanced and reasonable process, high efficiency and high practicability. By high-valued utilization of the wine brewing byproduct yellow water, resource waste and environmental pressure are reduced.

Description

technical field [0001] The application relates to the field of food chemistry, in particular to a method for preparing short-chain fatty acid glycerides. Background technique [0002] In the traditional solid-state fermentation winemaking process, the leaching water of the fermented grains continuously leaks from the upper layer to the bottom of the cellar, which may easily cause the moisture in the bottom fermented grains to increase. In order to improve the quality of wine and distillation efficiency, this part of water must be separated from the fermented grains. This part of the water is yellow water. Yellow water is a by-product of the solid-state fermentation process of winemaking. It is a variety of metabolites formed by complex reactions of nutrients under the action of microorganisms. It contains nitrogen-containing compounds, alcohols, esters and a large number of short-chain fatty acids. The processing and application of yellow water has always been a research ho...
