Abstract

The invention discloses a phyllostachys pracecox shoot dietary fiber and a preparation method thereof. The preparation method comprises the following steps: preprocessing phyllostachys pracecox shoots, then extracting through alkali liquor and acid liquor respectively, drying, fermenting through trichoderma viride, drying, and crushing to obtain the phyllostachys pracecox shoot dietary fiber. The phyllostachys pracecox shoot dietary fiber provided by the invention is prepared by using juiced shoot residues as a raw material to ensure that the utilization rate of the phyllostachys pracecox shoots is greatly increased, the cost of producing the dietary fiber is lowered, and the problem of environmental pollution caused by shoot residue waste is also effectively solved. According to the preparation method, a chemical method and a fermentation method are combined to ensure that the purity of the prepared phyllostachys pracecox shoot dietary fiber is remarkably superior to that of the phyllostachys pracecox shoot dietary fiber in the reported prior art, and the content of the water-soluble dietary fiber is increased; under the same experiment method and condition, the water binding capacity, the swelling property and the water binding capacity of a finished phyllostachys pracecox shoot dietary fiber product are superior to those of a single chemical method and a single fermentation method, and the phyllostachys pracecox shoot dietary fiber is improved in color, and the application value of the phyllostachys pracecox shoot dietary fiber is improved.

Description

technical field [0001] The invention belongs to the technical field of dietary fiber food, and in particular relates to a dietary fiber of thunder bamboo shoots and a preparation method thereof. Background technique [0002] Dietary fiber refers to the general term of polysaccharide carbohydrates and lignin that are not digested by the human body, and can be divided into two categories: water-soluble dietary fiber and water-insoluble dietary fiber. Dietary fiber (DF) is known as the "seventh nutrient" after water, protein, fat, carbohydrates, minerals, and vitamins, also known as "intestinal scavenger". Dietary fiber has a strong ability to hold water and oil. Nutrition survey data show that dietary fiber can effectively reduce and prevent the occurrence of coronary heart disease, diabetes, hypertension, obesity, myocardial infarction, colitis, constipation and other diseases. In addition, dietary fiber can delay and reduce the absorption of harmful substances such as heavy...
