Method for extracting dietary fiber from leftovers of bamboo shoots

Abstract

The invention discloses a method for extracting dietary fiber from leftovers of bamboo shoots, comprising the following steps: removing earth from the heads of aged bamboo shoots cut in the processing of the bamboo shoots, peeling the husks of the bamboo shoots, cleaning, squeezing and separating bamboo juice and bamboo shoot residuals; and processing the bamboo shoot residuals with steam explosion and ultrafine powder technology to obtain high-quality diet fiber. The method can be used for recovering and reutilizing the heads of the bamboo shoots to prepare and process the dietary fiber, thereby changing wastes into valuables, achieving good application prospect, finding a new way for the comprehensive utilization of the bamboo shoots. By the method, the additional value of the bamboo shoot product is increased, the resource waste is reduced, the environment is protected. Therefore the method has good social and economical benefits.

Description

technical field [0001] The invention relates to a processing method of bamboo shoot products, in particular to a method for extracting bamboo juice and dietary fiber by using bamboo shoot leftovers of bamboo shoots, and belongs to the technical field of food processing. Background technique [0002] Fresh bamboo shoots contain 90% water, 4% fiber, 3% protein, 2.5% total sugar, and about 0.5% fat. They are rich in various trace elements. Bamboo shoots are sweet in nature and slightly cold. , constipation, diabetes all have certain curative effect. Bamboo shoots are high-fiber, low-fat, and nutritious ideal dietary fiber raw materials. They are deeply loved by people. They are known as "the first vegetarian product" and are an ideal dietary fiber raw material. [0003] Bamboo shoots are an important food resource with high nutrition. Each part of bamboo shoots contains a variety of nutrients, including potassium content as high as 4%, protein 2.6%, and amino acid 0.69%, which...

Problems solved by technology

Especially for bamboo shoots for export, the requirements for raw materials are even stricter. During processing, only the tips of the young bamboo shoots are taken, and about 70% of the remaining bamboo shoots are discarded as leftovers. The utilization rate of raw materials is too low, resulting in high production costs.

Causes a great waste of bamboo shoot resources, these wastes must be transported to the suburbs for stacking, which requires a lot of freight and seriously pollutes the environment
