Problems solved by technology

On the one hand, in order to improve the taste and texture of dietary fiber-fortified foods, the water-insoluble dietary fiber of naked oats can be pulverized; the pulverized naked oat dietary fiber has little negative impact on the texture of dough, but its efficacy is relatively poor, and It is not recognized by consumers; on the other hand, although the dietary fiber of flaky naked oats has better efficacy and is easy to be recognized in food, it will greatly hinder the formation of gluten after being added to flour-based foods, and the appropriate amount of addition is often in the 5% or less

preparation example Construction

[0024] The invention provides a method for preparing softened microporous naked oat water-insoluble dietary fiber, comprising the steps of:

[0025] S1 (fermentation and enzymatic hydrolysis): Activate the compound starter with warm water and gradually dilute it to 400-2000 times, then fully mix it with naked oats, so that the microorganisms and enzymes are evenly distributed in the naked oats, and the water content is 28%- 45% of the mixed material; the mixed material is placed in a tank-type fermentation reactor, stacked naturally (covered on the surface, without compaction), and fermented at 28-42°C for 24-48h; wherein, the composite starter includes Saccharomyces cerevisiae and Lactobacillus lactis; the viable count of Saccharomyces cerevisiae is not less than 1×10 8 CFU / g, the number of live bacteria of Lactobacillus is not less than 1×10 7 CFU / g; the mass ratio of naked oats and compound starter (before activation) is 100: (0.02-0.1);

[0026] S2 (microporous treatment...

Embodiment

[0030] This example provides a method for preparing softened microporous naked oat water-insoluble dietary fiber, comprising steps:

[0031] S1 (fermentation and enzymatic hydrolysis): 0.5kg of compound starter (the number of live bacteria of S. 8 CFU / g, the number of live bacteria of Lactobacillus is not less than 1×10 7 CFU / g) was diluted to 50kg with warm water at 30°C, and then diluted to 450kg after standing for 20 minutes to obtain the diluted bacterial solution;

[0032] Fully mix the diluted bacterial solution and 1000kg of naked oats, so that the microorganisms and enzymes are evenly distributed in the naked oats, and a mixed material with a water content of 35% is obtained;

[0033] The mixed material is placed in a tank-type fermentation reactor, stacked naturally (the surface is covered with a film, and no compaction is required), and fermented at 28-42°C for 36 hours to obtain naked oats after fermentation and enzymolysis;

[0034] S2 (microporous treatment): Mi...

Abstract

The invention relates to a softened micro-pore naked oat water-insoluble dietary fibre and a preparation method thereof. The preparation method comprises the following steps: uniformly mixing a composite leavening agent with naked oats to obtain mixed materials; fermenting the mixed materials to obtain fermented naked oats subjected to enzymolysis; uniformly mixing the fermented naked oats subjected to enzymolysis with baking soda, and adopting a screw extruder to perform extrusion-explosion spraying treatment; curing and expanding the naked oats to form a great number of penetrating micropores with inner diameters of 50-300 [mu]m, thereby obtaining extruded and ,exploded andsion sprayed materials; sequentially adding a hydrogen peroxide aqueous solution and a sodium hypochlorite aqueous solution into the extruded and, exploded andsion sprayed materials to perform discolouring, washing, and drying. The softened micro-pore naked oat dietary fibre provided by the invention is good in softness, has small negative effects on a texture after the softened micro-pore naked oat dietary fibre is added into food due to the presence of a great number of micropores, and can lock water, so thatproduct texture hardening is inhibited, and aging retrogradation is delayed; and meanwhile, the colour is whiter, brighter and more beautiful in comparison with that of a common product.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a softened microporous naked oat water-insoluble dietary fiber and a preparation method thereof. Background technique [0002] Dietary fiber is essential to a healthy diet. Fiber plays an important role in maintaining a healthy digestive system. Adequate fiber intake can also prevent cardiovascular disease, cancer, diabetes and other diseases. [0003] Naked oats have a wide range of sources, and their ingredients contain high water-soluble dietary fiber and glucan, while the content of water-insoluble dietary fiber is also high. In general, research and development personnel and enterprises focus more on the extraction of water-soluble dietary fiber and dextran, and water-insoluble dietary fiber is often used as a by-product, which cannot be processed and utilized well. [0004] In fact, water-insoluble dietary fiber has a clear effect in preventing constipation and col...
