Abstract

The invention discloses a compound bamboo shoot wall breaking enzyme and a preparation method of bamboo shoot dietary fiber. The compound bamboo shoot wall breaking enzyme comprises cellulose, xylanase and hemicellulase. Wall breaking process via enzyme hydrolysis, wall breaking process via extrusion and superfine crushing process are sequentially carried out on fresh bamboo shoot heads, thus preparing the bamboo shoot dietary fiber. The method crushes the cellular tissue of the shoot heads to the greatest degree, the compound wall breaking enzyme has full hydrolysis, the wall breaking rate of the cellular tissue of the shoot heads is high, and soluble dietary fiber in the prepared bamboo shoot dietary fiber has high content.

Description

technical field [0001] The invention relates to a method for preparing dietary fiber from bamboo shoots, in particular to a method for preparing dietary fiber from bamboo shoots using bamboo shoot heads from bamboo shoot processing waste as raw materials. Background technique [0002] Dietary fiber generally refers to polysaccharide carbohydrates and lignin that are not digested and absorbed by the human body. It is called the "seventh largest nutrient" required by humans, also known as "intestinal scavenger". Insoluble two. Soluble dietary fiber (SDF) mainly includes storage substances and secretions of plant cells, as well as microbial polysaccharides and synthetic polysaccharides. Its main components are gums, such as pectin, gum, seed gum, agar, laminan carboxymethylcellulose etc., can slow down the digestion speed and excrete cholesterol quickly, help regulate the function of the immune system, promote the discharge of toxic heavy metals in the body, and have more obvi...
