Problems solved by technology

This is accompanied by three main problems: first, the acid-base interaction in the gel extraction process of this type of process is uneven, and the molecular structure of agarose polysaccharide is complex and changeable, resulting in difficult product quality control and poor uniformity; second, the traditional When the process is treated with high-temperature lye, part of the agar will be lost with the hot lye, resulting in a decrease in product yield; third, in the traditional process, due to the different reaction rates and different reaction intensities of alkali treatment, in order to ensure the utilization of raw materials, it is often necessary to Increase the concentration of alkali, resulting in an increase in the amount of alkali, and at the same time, the amount of water used in the subsequent rinsing process increases, and the pressure of sewage treatment increases

Abstract

The invention provides a method for microwave extraction of asparagus agar, and belongs to the technical field of agar production. According to the method, the reforming effect of microwaves on agaropectin and agarose molecules is utilized; alkali treatment efficiency is increased, precision is improved, so that the alkali consumption is reduced, the product uniformity is improved, the productionquality stability is improved, the product loss is reduced with increased raw material utilization rate, the yield is improved, the sewage treatment pressure is relieved, the water consumption and thesewage treatment capacity are reduced, and the overall extraction cost is reduced by 6-10%.

Description

technical field [0001] The invention relates to the technical field of agar production, in particular to a method for extracting asparagus agar by microwave. Background technique [0002] The technical process of using asparagus to extract agar (agar) has existed for a long time in our country. The main process is: alkali treatment, rinsing, bleaching, acid treatment, rinsing, gel extraction, filtration, gelation, physical drying , Crushing and granulating, drying and milling. This is accompanied by three main problems: first, the acid-base interaction in the gel extraction process of this type of process is uneven, and the molecular structure of agarose polysaccharide is complex and changeable, resulting in difficult product quality control and poor uniformity; second, the traditional When the process is treated with high-temperature lye, part of the agar will be lost with the hot lye, resulting in a decrease in product yield; third, in the traditional process, due to the ...
