Embodiment Construction

[0020] The following specific embodiments are further detailed descriptions of the present invention, and do not constitute any limitation to the present invention.

[0021] Preparation of high-purity water-soluble chitosan:

[0022] The present invention first prepares high-purity water-soluble chitosan by further deacetylating crude chitin with a purity of 85% in a homogeneous system, and the specific method is as follows:

[0023] a. Dissolve crude chitin with a purity of 85% in acetic acid with a concentration of 3-6% whose weight is 10 times that of the raw material, raise the temperature to 35°C-40°C, and keep it in this temperature range for 4-6 hours, Then cool to room temperature, add dropwise 35-45% sodium hydroxide solution until no white flocculent precipitate appears, centrifuge and wash the white precipitate until neutral;

[0024] b. Dissolve the precipitate again in acetic acid with a concentration of 2-4%, raise the temperature to 40°C, and keep it at this te...

Abstract

A tea containing water soluble chitosan and its preparation method is composed of 100wgt tea and 2wgt water soluble chitosan. The preparation method includes the step of filling water soluble chitosan through spraying method during rolling tea processing. The present invention tea containing water soluble chitosan can eliminate free radical in vivo and other toxin, regulate physiological balance, prevent aging, prevent diseases of middle-aged people and other effects, play important role in adjusting the acid-base balance of human body fluid and improving human body internal environment.

Description

technical field [0001] The present invention relates to a kind of tea and its preparation method, more specifically, to a kind of tea containing water-soluble chitosan and its preparation method. Background technique [0002] Chitin widely exists in the shells of lower animals, especially arthropods, such as shrimps, crabs, insects, spiders, etc., and also exists in the cell walls of lower plants, such as fungi, algae, yeasts, etc. Linear polysaccharide biopolymers. Under the action of various biological enzymes, it can produce chitin with smaller molecular weight and chitosan with different molecular weight and deacetylation degree through a series of steps such as degradation and deacetylation. Chitosan is a derivative of chitin, also known as soluble chitin, deacetylated chitin, chitosan, chitosan, obtained by a certain degree of deacetylation of chitin, and its chemical name is (1,4)- 2-Amino-2-deoxy-β-D-glucan. Among the many natural polysaccharides, chitin and its m...
