Problems solved by technology

CN104086615A discloses a method for preparing mogroside V from Luo Han Guo. The method is to crush the Luo Han Guo, high-pressure treatment, supercritical fluid extraction, HP-20ss resin chromatography, concentration, and drying to obtain the product. The purity of mogroside V in the product is It is more than 70%, but due to the limitation of one-time processing capacity of supercritical fluid extraction equipment, it is not conducive to continuous large-scale production, and the yield and purity of mogroside need to be further improved

Abstract

The invention relates to a method for extracting mogrosides from Siraitia grosvenorii fruits. Raw materials are subjected to pretreatment, primary extraction, pumping filtration, secondary extraction, pumping filtration, multi-stage filtration, decompress concentration and drying, and the mogrosides are obtained. According to a secondary extraction method adopting ultrasonic-assisted secondary water extraction, Siraitia grosvenorii fruit powder particles are vigorously oscillated in a solution in the presence of ultrasonic waves, and motion of soluble components is facilitated. Meanwhile, the ultrasonic waves performing large-amplitude motion propagate in a medium and can form zigzag cyclical fluctuation, the radiation intensity in the sound wave propagation direction is high, raw material particles are further broken, dissolution of the soluble substances is facilitated, and the yield of the mogrosides is increased to a certain extent. By means of multi-stage filtration including pumping filtration, ultrafiltration, nanofiltration and the like after water extraction, the extraction purity is high. The whole extraction process is simple and easy to operate, continuous large-scale production can be realized, chemical reagent residues are avoided, and product quality safety is guaranteed.

Description

technical field [0001] The invention relates to a method for extracting mogroside from Luo Han Guo, in particular to a technology for extracting mogroside that can be used in industrial production. Background technique [0002] Luo Han Guo is the fruit of the Cucurbitaceae plant Luo Han Guo. As a medicinal and edible Chinese herbal medicine, Luo Han Guo is cool in nature, sweet in taste, and belongs to the large intestine meridian. Mogroside is the main sweet component in Luo Han Guo, the content is generally 3.755%-3.858%. It is a low-calorie, non-nutritional, non-fermentative sweetener, and its sweetness can reach 300 times the sweetness of sucrose. General pharmacology Scientific research shows that it has high safety in application and is an ideal sweetener for obese people and diabetic people. [0003] Mogroside is a triterpene saponin, which is easily soluble in water, ethanol, methanol and other solvents. It is stable in nature and will not be destroyed by continuous...
