Problems solved by technology

[0004] The stipe of Agaricus blazei accounts for about 25-28% of the dry mass of Agaricus blazei. It is rich in polysaccharides, proteins, vitamins, mineral elements, dietary fiber and other nutritional and functional components. The content of dietary fiber far exceeds that of the mushroom umbrella, but Due to its high fiber content and poor palatability, it is difficult to be fully developed and utilized, and it is often the waste in the processing of Agaricus blazei products

Abstract

The invention discloses a preparation technology and application for an Agaricus blazei Murill. dietary fiber. The preparation technology comprises the following steps of: S1: drying and smashing Agaricus blazei Murill. stipe to obtain Agaricus blazei Murill. stipe coarse powders; S2: carrying out oligomerization processing on the Agaricus blazei Murill. stipe coarse powders to obtain Agaricus blazei Murill. stipe fine powders; S3: mixing the Agaricus blazei Murill. stipe fine powders with water, carrying out sterilization, inoculating a mixed living bacteria agent, and carrying out fermentedcultivation to obtain fermentation liquor; and S4: drying and smashing the fermentation liquor to obtain Agaricus blazei Murill. fiber powders. According to the preparation technology, a water material, i.e., the stipe, generated by Agaricus blazei Murill. processing is used for preparing the Agaricus blazei Murill. fiber powders, and resources are saved. Meanwhile, the prepared Agaricus blazei Murill. fiber powder has a high SDF (soluble dietary fiber) content and has good expansibility, water holding capacity and oil holding capacity, and the excellent properties provide a good application prospect for applying the Agaricus blazei Murill. fiber powders in food industry. Meanwhile, Agaricus blazei Murill. bread is provided, the Agaricus blazei Murill. fiber powders are added into the Agaricus blazei Murill. bread, and the obtained bread has a high content of high-quality dietary fibers and a low content of fat and cholesterol, and conforms to the health requirements of modern people.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation process and application of Agaricus blazei dietary fiber. Background technique [0002] Dietary fiber (DF) usually refers to a type of main component of plant cell walls that cannot be digested by human digestive enzymes or absorbed by the small intestine, including cellulose, hemicellulose and pectin substances, etc., which can be divided according to solubility For insoluble dietary fiber (insoluble dietary fiber, IDF) and soluble dietary fiber (soluble dietary fiber, SDF). IDF has the functions of preventing colon cancer and laxative, and SDF has physiological functions such as lowering cholesterol, preventing diabetes and cardiovascular diseases. Therefore, the content of SDF is an important factor affecting the physiological function of DF; however, the content of IDF in the composition of DF from natural sources is high, and the content of...
