Abstract

The invention discloses a method of using a steam explosion technology to extract and degum banana fibers. The method comprises the following steps: (1) carrying out steam explosion extraction; (2) performing a pre-acid treatment; (3) cleaning; (4) carrying out enzymatic degumming; (5) carrying out steam explosion degumming; (6) performing primary bleaching; (7) performing secondary bleaching; and (8) carrying out a post treatment. At first a pre-acid treatment is carried out, and then biological enzymes and steam explosion are combined to effectively increase the yield of banana fiber. At the same time, the residual gum content of banana fibers is reduced, and thus the environment pollution is avoided.

Description

technical field

[0001] The invention relates to the technical field of plant fiber preparation, in particular to a method for extracting and degumming banana fiber by steam explosion technology. Background technique

[0002] Banana fiber can be divided into banana stem fiber and banana leaf fiber. Banana leaf fiber is stored in the leaves of banana trees and belongs to leaf fiber; banana stem fiber is stored in the bast of banana tree and belongs to bast fiber; banana bast The main chemical component of banana bast is cellulose, followed by hemicellulose, lignin, pectin, water-soluble matter, fat wax, etc. It can be seen that although the cellulose content in banana bast is lower than that in flax and jute However, its content in banana bast is also about 60%. Compared with flax and jute, the content of hemicellulose and lignin in banana bast is higher, and the two account for 30% of the chemical composition of banana fiber Above, a large number of studies have shown that b...
