Abstract

The invention discloses an ultrasonic extraction process of saccharum officinarum polysaccharide. The process includes: firstly subjecting saccharum officinarum residue to microwave vacuum drying treatment, then crushing the saccharum officinarum residue, adding water into the saccharum officinarum residue powder and stirring the mixture evenly, then adding acid to adjust the pH value, then performing ultrasonic treatment, decocting the ultrasonic treatment liquid, and performing filtering to obtain a water extract, sending the water extract into an ultrafiltration device to conduct ultrafiltration treatment, then sending the ultrafiltrate into a centrifugal machine to conduct centrifugal treatment, concentrating the centrifugate to obtain a concentrated solution, adding ethanol into the concentrated solution and conducting standing, then carrying out centrifugal separation, and drying the obtained saccharum officinarum polysaccharide solution, thus obtaining saccharum officinarum polysaccharide. By adopting the microwave low temperature vacuum drying and ultrasonic wave synergistic treatment technology, the process provided by the invention ensures effective wall breaking, significantly improves the polysaccharide yield and antioxidant activity, and greatly enhances the extraction rate of saccharum officinarum polysaccharide.

Description

technical field [0001] The invention relates to the technical field of sugar processing technology, in particular to an ultrasonic extraction technology of sugarcane polysaccharides. Background technique [0002] Bagasse is the main by-product of the sugar industry. It is the main part left after sugar cane is mechanically pressed and harvested. It is a kind of agricultural solid waste. There are many provinces in our country where sugar cane can be planted, and each sugar factory produces a large amount of bagasse. It is of great significance to find a suitable way to comprehensively utilize bagasse. Studies have shown that polysaccharides extracted from bagasse have anti-tumor, anti-virus, hypoglycemic, hypolipidemic, and immune-enhancing effects. Extracting polysaccharides from bagasse for development and utilization is an effective way. Existing polysaccharide extraction methods include water extraction and alcohol precipitation method, microwave method, acid-base metho...
