Multi-strain composite brown rice solid-state fermentation inoculant, and preparation method and application thereof

Abstract

The invention discloses a multi-strain composite brown rice solid-state fermentation inoculant, and a preparation method and application thereof. The multi-strain composite brown rice solid state fermentation inoculant comprises lactic acid bacteria, mould, saccharomycetes and neurospora, wherein a mass ratio of the lactic acid bacteria to the mould to the saccharomycetes to the neurospora is (2-8): (0-4): (0.1-8): (0.1-4). According to the invention, the inoculant is also used for preparing solid-state fermented brown rice-containing food, the content of soluble dietary fibers is remarkably increased and is increased by 138% compared with the content of soluble dietary fibers in non-solid-state fermented brown rice, the content of polyphenol substances is increased by 86% or above, the content of vitamin B2 and the content of vitamin E are increased by 30% and 91% respectively, and antioxidant activity is increased to 3.8 times or above of the antioxidant activity of the non-fermented brown rice; meanwhile, brown rice particles are whiter and smoother in appearance, the problem that brown rice is dark in color is solved, and taste is softer and more sticky; and a series of small-molecule flavor substances are generated through the metabolic process of different strains, so a brown rice product is endowed with unique flavor characteristics, and the taste of the brown rice product is more aromatic and rich.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a multi-species compound brown rice solid-state fermentation bacterial agent, a preparation method and an application thereof. Background technique [0002] Rice contains a variety of nutrients, including carbohydrates, proteins, lipids, vitamins and dietary fiber. Polished rice is processed by rice husking, grinding, polishing and other processes, and is mainly composed of rice endosperm; brown rice is directly processed by rice husking, which consists of peel (1% to 2%), aleurone layer and It consists of seed coat (4%-6%), germ (2%-3%) and starchy endosperm (89%-94%). Therefore, compared with polished rice, brown rice contains more nutrients and has higher nutritional value. Along with deepening gradually of people's cognition to the nutritive value of brown rice, the exploitation and utilization of whole grain food of brown rice has been paid more and more...

AI Technical Summary

Problems solved by technology

[0008] The third object of the present invention is to provide a kind of multi-species composite brown rice solid-state fermented bacterial agent in the solid-state fermentation of food containing brown rice, the multi-species The bacterial agent is used in solid-state fermented grain raw materials, which not only solves the problems of brown rice not easy to cook and rough taste caused by the high content of insoluble dietary fiber in the cortex of brown rice, but also increases the content of free polyphenols and enhances the antioxidant activity of brown rice in vitro. And greatly improve brown rice dark color, poor eating quality and other problems, significantly improve the quality of brown rice
