Semi-automatic extraction unit

solventfor the food industry

A kind of the method of the extraction without agriculture residual momordica grosvenori and water-soluble dietary fiber, comprising the following steps: (1) Siraitia grosvenorii is cleaned, squeezed the juice, pomace elution obtains extracting solution； (2) it boils, cooling, centrifugation ,extraction obtains extract； (3) aluminium oxide and activated carbon chromatography column for passing through tandem, collect efflux； (4) ultrafiltration membrance filter collects trapped fluid and permeate respectively； (5) nanofiltration, concentration: by ultrafiltration permeate nanofiltration membrane, trapped fluid and permeate are collected respectively, nanofiltration retentate fluid concentration is dry, obtains the residual mogroside of no agriculture； Nanofiltration permeate liquid is merged into concentration with ultra-filter retentate, it is dry, obtain the residual Siraitia grosvenorii water-soluble dietary fiber of no agriculture. Gained mogroside and the equal non agricultural chemical residuum of water-soluble dietary fiber product；The content of glycosides V is up to 90.6%, and yield is up to 96.3%；The purity of water-soluble dietary fiber is up to 95%, and yield is up to 91%；The method of JNBAN siraitia grosvenorii extraction processing line is simple, easy to operate, is suitble to industrialization production.
