Abstract

The invention discloses a method for ensiling enteromorpha and a method for preparing enteromorpha crude polysaccharide. According to the method for ensiling the enteromorpha and the method for preparing the enteromorpha crude polysaccharide, a compound microbial agent which is a mixture of lactobacillus plantarum, lactobacillus brevis, bacillus siamensis and bacillus psychrosaccharolyticus is used for carrying out enteromorpha ensiling processing; after the enteromorpha is processed through the method for ensiling the enteromorpha, a solid cellulose structure can be easily resolved to be utilized; due to the fact that the acid hydrolysis technology is adopted, consumption of acid can be reduced, the degradation efficiency is also improved, the content of solid content in hydrolysate is increased, concentration does not need to be carried out, spray drying can be directly carried out, and production cost is reduced. The prepared enteromorpha crude polysaccharide can improve immunity and stress resistance capacity of crops. The method for ensiling the enteromorpha and the method for preparing the enteromorpha crude polysaccharide effectively solve the technical problems of enteromorpha ensiling processing, achieve long-term storage of the fresh enteromorpha, and are simple in operation, small in number of technological processes, low in production cost and applicable to industrialized mass production.

Description

technical field [0001] The invention belongs to the field of deep development and utilization of Enteromorpha resources, and in particular relates to a method for green storage of Enteromorpha and a method for preparing crude polysaccharides of Enteromorpha. Background technique [0002] Enteromorpha is a genus of Chlorophyta Ulvaceae. Enteromorpha itself is rich in carbohydrates, protein, crude fiber, fatty acids and vitamins, and also contains iodine, calcium, phosphorus, sodium, iron, potassium and other trace elements. Due to the specificity of the marine living environment, the active ingredients of Enteromorpha have unique physiological characteristics, so Enteromorpha is a seaweed resource with great development value. [0003] Due to the seasonality of Enteromorpha, when the weather is hot from June to August, the moisture content of the salvaged Enteromorpha is about 90%. It cannot be stored for a long time in high temperature weather, and it will rot and deteriora...
