Method for producing bamboo shoot dietary fibers by using bamboo shoot processing waste and byproducts

Abstract

The invention discloses a technique for preparing functional dietary fibers by using bamboo shoot processing waste and byproducts and the like as raw materials. The method comprises the following steps: firstly, recovering fresh bamboo shoot processing waste and byproducts, including bamboo shoot tips, bamboo shoot shells, bamboo shoot joints, bamboo shoot coats and bamboo shoot processing leftovers, cleaning, drying, crushing, keeping the water content in the treated raw material powder between 10 and 30 percent, pressing, activating, crushing and obtaining bamboo shoot dietary fibers in bamboo shoot tips, bamboo shoot shells and bamboo shoot joints. The technique disclosed by the invention is simple and convenient, the production cost is low, the product quality is stable, and industrial production can be realized easily. The water retaining capacity and expanding capacity of the obtained bamboo shoot dietary fibers are much advantageous over common dietary fiber products, the content of soluble dietary fibers is increased, and a physical effect can be better played. The bamboo shoot dietary fibers can serve as a dietary fiber supplying agent, functional food and the like, the economic value of the bamboo shoots can be obtained, and the comprehensive utilization of bamboo shoot resource can be realized.

Description

1. Technical field [0001] The invention relates to a production method of dietary fiber, in particular to a method for producing bamboo shoot dietary fiber by using bamboo shoot processing waste and by-products. 2. Technical background [0002] Dietary fiber is mainly polysaccharides and lignin that cannot be digested and absorbed by the human body, and is called the "seventh largest nutrient". Studies have shown that dietary fiber has very important physiological functions for human health. Dietary fiber can be divided into soluble dietary fiber (Soluble dietary fiber, SDF) and insoluble dietary fiber (Insoluble dietary fiber, IDF) according to its water solubility. SDF has the functions of lowering human serum cholesterol, preventing gallstones, diabetes, hypertension and heart disease, etc. effect; while IDF has a good effect on preventing obesity, constipation, and intestinal cancer. [0003] Bamboo shoots are a kind of traditional food that is loved by people. It has ...

Problems solved by technology

However, in the bamboo shoot processing process, the utilization rate of bamboo shoot processing is not high, and a large amount of fresh bamboo shoot processing waste and by-products such as bamboo shoot heads, bamboo shoot shells, bamboo shoot nodes, bamboo shoot clothing, and bamboo shoot processing scraps are produced, rot and mildew, and serious Harm the ecological environment

[0004] Fresh bamboo shoot processing waste and by-products such as bamboo shoot heads, bamboo shells, bamboo shoot joints, bamboo shoot skins, and bamboo shoot processing scraps are rich in dietary fiber, but their wall thickness, high lignified fiber content, rough tissue structure, and processing quality Restricted, difficult for the body to absorb
