Problems solved by technology

Especially in the production process of cereal flour, the raw material of cereal grains is mainly to be crushed and then baked or not baked. After adding dextrin and sucrose, they are mixed into brewed cereal powder. This type of cereal powder has the following defects: (1) If the product is plain grain powder, the flavor is relatively ordinary and has no obvious characteristics; (2) if the product is flavored grain powder, sucrose will be added for seasoning, and dextrin is usually added to this type of product to improve the impact of the grain powder. Tonality, the preparation performance of the grain powder obtained by this type of process is still low, and it is easy to agglomerate under the condition of 80-90 ° C. At the same time, this type of process lacks its own naturalness and reduces the nutrition of the grain; (3) At present, the processing and manufacturing of grains is mainly rough processing, and the natural advantages of grains have not been better utilized. Therefore, the forms of grain products on the market are single and the added value is low

Embodiment 1

[0024] This embodiment discloses a preparation process of flavor nutritional fermented grain brewing powder for agricultural biological fermentation, which includes the following steps:

[0025] Step 1: Grain pretreatment: use grain kernels as raw materials, remove impurities, shriveled grains, and bad grains and then clean them;

[0026] Step 2: Grain soaking and steaming: Weigh the grain, soak for 2 hours, drain with gauze, and steam for 30 minutes;

[0027] Step 3: Sterilization: put the matured grains in step 2 into a sterilization tank for sterilization, cool to the set temperature after sterilization, and then transfer the grains to the fermenter;

[0028] Step 4: Preparation of starter: Inoculate Aspergillus, lactic acid bacteria, and yeasts into MRS medium respectively, and culture them statically at 28°C for 16 hours to activate them, and then inoculate them in MRS with a volume fraction of 3% of the medium. Continue to cultivate at the same temperature for 10 hours,...

Abstract

The invention provides a special-flavor nutritional-type fermented cereal brewing powder for agricultural biological fermentation and a preparing technology thereof. The technology comprises the following steps of 1, cereal pretreatment; 2, cereal soaking and curing; 3, sterilization; 4, preparation of a fermentation agent; 5, inoculated fermentation; 6, low-temperature drying; 7, smashing. According to the prepared fermented cereal powder, the cereal is effectively degraded into polysaccharide and reducing sugar through the compound fermentation effect of aspergillus, lactic acid bacteria andsaccharomycetes, the cereal is subjected to good gelatinization pretreatment, in the combination with a freeze-drying technology, there are many gaps in the obtained cereal powder tissue structure, at the high brewing temperature, powder particles are quickly re-hydrated, and the brewing performance is good; before saccharose, dextrin and other additives are added into the fermented cereal powder, the fermented cereal powder has natural sweet and sour flavor, high nutritional value, good brewing performance and an excellent market prospect.

Description

technical field [0001] The invention relates to the technical field of biologically fermented food, in particular to a flavor and nutritional fermented grain brewing powder and a preparation process thereof. Background technique [0002] Bio-fermented food is an indispensable and important food in people's daily life. Bio-fermented food generally has various health effects such as promoting digestion, softening blood vessels, lowering blood pressure, preventing cancer, beautifying, losing weight, and delaying aging. Among them, grains and fruits are two essential food categories in people's daily life. Grains contain a variety of nutrients, such as oats and barley are rich in B vitamins and β-glucan, black rice contains potassium Various minerals such as magnesium and magnesium, and organic trace elements such as selenium and iodine. [0003] The combination of grain and fruit for biological fermentation has both the nutritional and health functions of fruit and fermented l...
