Product containing rich low-viscosity resistant starch and preparing method of product

The invention provides a product containing rich low-viscosity resistant starch. A preparing method of the product comprises the following steps of: (1) uniformly mixing raw starch and a buffer solution with the pH being 4.0 to 7.5 according to a mass-to-volume ratio being 1:7 to 1:13; using the obtained mixture as a substrate; adding pullulanase into the substrate according to the adding proportion being 20 to 350U/g; pouring the mixture into a vacuum packaging bag; sealing an opening; and performing an enzymatic hydrolysis reaction for 10 to 90min under the conditions of 50 to 450 MPa and 45 to 75 DEG C; and (2) continuously performing an enzymatic hydrolysis reaction for 5 to 48h under the conditions of normal pressure and 45 to 75 DEG C at the stirring speed being 90 to 150rpm; then, passivating the enzyme activity for 10 to 20min in an ice bath being 0 to 4 DEG C; removing liquid supernatant through centrifugation; and performing drying, powder grinding and sieving to obtain the product. The resistant starch product obtained through the preparing method provided by the invention has the advantages that the viscosity is as low as 60cP; and the resistant starch content is as high as more than 43 percent. The product can be used as a functional food ingredient to be added into high-fiber food, and can also be used as low-energy filling agents to be applied to low-sugar low-grease and fat losing food.

Development and preparation method of bacterial cellulose and Chinese wolfberry juice compound diet food

The invention relates to process development and product preparation of a Chinese wolfberry diet food, and belongs to the field of foods. The preparation method comprises the following steps of takingfresh Chinese wolfberry as a substrate, and carrying out peeling, seed removing, homogenization and sterilization to obtain Chinese wolfberry primary pulp; and meanwhile, inoculating gluconacetobacter xylinus into a preferred fermentation culture medium, performing fermentation to obtain bacterial cellulose, cutting or grinding the bacterial cellulose into bacterial cellulose particles or powderwith a certain specification, and compounding the bacterial cellulose particles or powder with the Chinese wolfberry primary pulp, so that the volume ratio of the bacterial cellulose in the Chinese wolfberry fermented juice reaches 20-60%. The bacterial cellulose and Chinese wolfberry juice compound diet product obtained by the method has the advantages of high satiety, high fiber content, rich Chinese wolfberry flavor, crisp and smooth taste and the like, and is suitable for obese people to eat. The product can achieve the purpose of losing weight through low calorie, high fiber and digestionpromotion, and is a safe and healthy high-fiber food. A new direction is provided for deep processing and product development of the Chinese wolfberry.
