Method for preparing bamboo leaf polysaccharides from bamboo pulp

Abstract

The invention discloses a method for preparing bamboo leaf polysaccharides from bamboo pulp. The method comprises the following steps of: (1) adding amylase into the bamboo pulp to perform enzymolysis so as to remove starch, and adding lipase to perform enzymolysis so as to remove fat, then adding protease to perform enzymolysis so as to remove protein, and then performing high-temperature enzyme inactivation and centrifugal treatment to obtain a clarifying solution; (2) filtering the clarifying solution by adopting an ultrafiltration membrane device to obtain a concentrated solution of the bamboo leaf polysaccharides; and (3) drying the concentrated solution of the bamboo leaf polysaccharides to obtain powder of the bamboo leaf polysaccharides. According to the method disclosed by the invention, the preparation ways of the bamboo leaf polysaccharides are expanded, the cost is greatly reduced, the promotion of the development and the implementation of industrialization of technologies for the bamboo leaf polysaccharides can be benefited, the added value of bamboos, namely peculiar economic forest products in China can be further improved, the development of natural product resources is enriched, and the method further has a huge promotion effect on the economic development of the forestry and agriculture in China.

Description

technical field [0001] The invention relates to the technical field of bamboo leaf polysaccharides, in particular to a method for preparing bamboo leaf polysaccharides from bamboo pulp. Background technique [0002] Bamboo is a perennial evergreen plant of the Poaceae (poaceae) Bamboo subfamily (Bambusodeae), and is one of the most valuable plants in the world today. Bamboo leaves are widely used among the Chinese people, and have a long history of medicinal and edible use. They are good heat-clearing and detoxifying medicines. According to Chinese literature, bamboo leaves are light in nature, slightly astringent, cold, sweet and bitter in taste, and have the functions of clearing away heat and diuresis, improving eyesight, detoxification and hemostasis. Bamboo Polysaccharides, as a plant active polysaccharide, is a heteropolysaccharide with a medium molecular weight. Bamboo leaf polysaccharides are mainly composed of six monosaccharides: rhamnose, arabinose, xylose, mann...

Problems solved by technology

[0003] At present, although bamboo has been widely used in industrial production, handicraft production, food processing, etc., most of them only use the whole plant, and the utilization of bamboo leaves is very limited, and its development is obviously lagging behind.
