The invention discloses a method for increasing oligosaccharide content in pellet feed for pigs. The method comprises the following steps: mixing a starch raw material with water according to a mass ratio of 1: 1.20; adding medium-temperature alpha amylase and high-temperature-resistant alpha amylase for enzymolysis under the condition of 6872 DEG C; directly mixing an oligosaccharide solution obtained by enzymolysis with raw materials of the pellet feed for the pigs; and carrying out steam conditioning, extrusion granulation and ventilation cooling to obtain the pellet feed containing oligosaccharide. According to the method, the process of preparing the oligosaccharide through enzymolysis of the starch is combined with the production process of the pellet feed, so that a high-energy-consumption drying link in the traditional oligosaccharide production is omitted, the production cost is remarkably reduced, and the reduction amplitude can reach 3537%; the oligosaccharide content in the pellet feed is stabilized at 1.702.60%, the water content is not higher than 13.5%, the pellet feed meets the safe storage standard, and the pellet feed has good industrial application value.

The present application relates to a kind of spent grain protein peptide and its preparation method and application. Specifically, with beer brewing by-product spent grain as raw material, it is prepared by protease enzymolysis to prepare spent grain enzymolysis oligopeptide, and it is proved by mouse in-vivo experiment that the enzymolysis complex has the function of improving blood sugar, obesity, blood fat. On this basis, from the enzymolysis product, the key blood sugar reducing active peptide segment FPQPPQ, FPQQPPFG, FPQPQQPFP is identified, and it is verified that its alpha amylase inhibition rate is superior to the same concentration of acarbose. The spent grain protein peptide complex and spent grain protein peptide of the present application have the effect of reducing blood sugar, and can be applied to the development of food, health food, medicine and the like.

The invention discloses corn meal replacement powder capable of promoting growth of intestinal probiotics and a preparation method of the corn meal replacement powder. The corn meal replacement powder is prepared from the following components in percentage by weight: 76.9%-88.5% of enzyme unfrozen dry corn flour, 10%-20% of Chinese yam powder, 0.3%-0.7% of stevioside, 0.4%-0.8% of propylene glycol alginate, 0.4%-0.8% of xanthan gum and 0.4%-0.8% of sodium carboxymethyl cellulose. The preparation method comprises the following steps: mixing the corn flour and water, pulping, and adding anhydrous calcium chloride and alpha-amylase for enzymolysis; carrying out suction filtration on the enzymatic hydrolysate, adding water to wash the precipitate, freeze-drying the obtained precipitate, and crushing to obtain enzyme-unfrozen dry corn flour; all the components are uniformly stirred and mixed according to the proportion. According to the meal replacement powder disclosed by the invention, the corn is used as a main material, starch in the corn flour is enzymatically hydrolyzed by using amylase, energy provided by the meal replacement powder is reduced to the greatest extent, the content of lysine in the added Chinese yam is rich, the nutritional structure of the meal replacement powder is improved, the readjusted taste and mouth feel are given to the meal replacement powder, and the utilization space of the corn is expanded.

The invention belongs to the technical field of food processing, and relates to a preparation method of a Chinese yam fermented beverage and a product thereof, the preparation method comprises the following steps: pulping Chinese yam, gelatinizing, and carrying out enzymolysis treatment by using alpha amylase to obtain a first mixture; and performing mixed fermentation on the first mixture by using streptococcus salivarius subsp. Thermophilus and lactobacillus delbrueckii subsp. Bulgaricus to obtain the fermented beverage. The beverage prepared from Chinese yam as a raw material is extremely easy to layer and precipitate, and starch in the Chinese yam is hydrolyzed by alpha-amylase, so that on one hand, the fermentability of the Chinese yam is enhanced, the fermentation efficiency is improved, and the generation of flavor substances in the fermentation process is promoted; on the other hand, the stability of the product in the shelf life is improved to a certain extent. The prepared product is fresh, cool, soft and rich in nutritional value.

The invention discloses a modification technology for soybean soluble dietary fibers based on UHP. The modification technology comprises the following steps: pretreating SDF raw materials; extracting soluble dietary fibers from the bean dregs; determining basic physicochemical properties, and determining monosaccharide composition; determining the WHC and the OHC of the SDF; analysis is carried out through a scanning electron microscope (SEM), differential scanning calorimetry (DSC) and X-ray diffraction (XRD); soluble dietary fibers of bean dregs are modified by adopting a UHP technology, and a result shows that WHC, OHC and SC of the bean dreg dietary fibers, the antioxidant capacity, the glucose adsorption capacity, the alpha-amylase inhibition capacity and the alpha-glucosidase inhibition capacity (p < lt >; 0.05), cholesterol adsorption capacity, in-vitro bile salt binding capacity and pancreatic lipase inhibition capacity, which indicate that the soybean dreg soluble dietary fiber adsorption capacity, in-vitro blood sugar reducing activity and in-vitro blood fat reducing property are better.
