Embodiment 1

[0043] This embodiment provides a kind of brown rice multigrain rice, which is mixed with brown rice, oats, barley, mung bean, red bean and pinto bean in a mass ratio of 60%, 20%, 5%, 5%, 5% and 5%. ;

[0044] The multi-species compound brown rice solid-state fermentation agent contains Lactobacillus plantarum, Aspergillus oryzae, Saccharomyces cerevisiae, and Neurospora californica, and the number of live bacteria of each strain is not less than 1×10 10 cfu / g;

[0045] The preparation method of described brown rice multigrain rice is as follows:

[0046] (1) Sieve brown rice, oats, barley, mung bean, red bean and pinto bean to remove other impurities in the materials and mix them evenly to obtain mixed brown rice, soak in drinking water for 3 hours, and dry at 40-50°C until the moisture content is 15% , sterilized at 121°C for 20 minutes before use.

[0047] (2) Activate Lactobacillus plantarum, Aspergillus oryzae, Saccharomyces cerevisiae, and Neurospora californica accor...

Embodiment 2

[0051] This embodiment provides a kind of brown rice miscellaneous grain rice, the preparation method is the same as that of embodiment 1, and the only difference from embodiment 1 is that the multi-species compound brown rice solid-state fermented bacterial agent is composed of Lactobacillus plantarum, Saccharomyces cerevisiae, Haoshimai Spores are mixed according to the mass ratio of 2:7:2.

Embodiment 3

[0053] Present embodiment provides a kind of brown rice cake, and bacterial agent is with embodiment 1, and described brown rice cake is only made by brown rice;

[0054] The preparation method of described brown rice cake is as follows:

[0055] (1) Select high-quality brown rice, sieve to remove impurities, soak in drinking water for 3 hours, dry at 40-50°C until the moisture content is 15%, and sterilize at 121°C for 20 minutes before use.

[0056] (2) Activate Lactobacillus plantarum, Aspergillus oryzae, Saccharomyces cerevisiae, and Neurospora californica according to the aforementioned method, mix according to the mass ratio of 3:1:6:2, and prepare compound sludge, and add The total mass of the compound bacteria slime is 0.4g, and the multi-strain compound brown rice solid-state fermentation bacteria agent is prepared.

[0057] (3) Brown rice and multi-strain compound brown rice solid-state fermented bacterial agent Add the solid-state fermented bacterial agent into the...

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...
