Embodiment 1

[0025] Take 1 kg of fresh Luo Han Guo, break it into pieces of 1-2 cm, add 2 kg of 40% ethanol aqueous solution, heat to 50°C, keep the temperature at 40-50°C, and soak for 10 hours. Filtrate with a 200-mesh filter to obtain the Luo Han Guo extract, and the waste pomace can be used to make fertilizer, etc. The pH value of the leachate is 5. The leachate is cooled to 25-30°C, passed through the first-stage pressure pump, and passed through the first ultrafiltration membrane separation module under a working pressure of 0.01-0.03Mpa, and the concentrated Luo Han Guo fiber, protein, pectin, impurities and ash are intercepted and separated A total of 80 grams is sent out from the first outlet; the remaining filtrate passes through the second stage nanofiltration membrane separation module under the working pressure of 0.04-0.06Mpa through the second-stage pressure pump, and intercepts and separates the concentrated mogroside solution with a concentration of 28 degrees Baumé, sent...

Embodiment 2

[0027] Take 1 kg of dried Luo Han Guo, break it into 0.5-1.5 cm pieces, add 10 kg of 50% ethanol aqueous solution, heat to 60°C, keep the temperature at 40-60°C, and soak for 15 hours. Filter with a 250-mesh filter to obtain the Luo Han Guo extract, and the waste pomace can be used for fertilizer production. The pH value of the leachate is 6. The leachate is cooled to 25-30°C, passed through the first-stage pressure pump, and passed through the first ultrafiltration membrane separation module at a working pressure of 0.02-0.05Mpa, and the concentrated Luo Han Guo fiber, protein, pectin, impurities and ash are intercepted and separated A total of 30 grams is sent from the first discharge port; the remaining filtrate is passed through the second stage of the pressure pump at a working pressure of 0.05-0.08Mpa through the second nanofiltration membrane separation module, and the concentrated mogroside solution is intercepted and separated, with a concentration of 26 degrees Baum...

Abstract

The extraction process of grosvenor's momordica fruit glycoside includes the following steps: breaking grosvenor's monordica fruit, adding ethyl alcohol solution, soaking for 5-15 hr. at 30-60 deg.C, filtering to obtain filtrate, cooling to 20-35 deg.C, making the filtrate pass through pressure pump and under the working pressure of 0.01-0.2 MPa feeding said filtrate into three membrane separation components successively: first stage, trapping and separating out concentrated grosvenor's monordica fruit fibre, protein, pectine and impurity which can be used for making organic fertilizer; second storage, vacuum drying the obtained concentrated grosvenor's monordica fruit glycoside solution to obtain grosvenor's monorica fruit glycoside product; and third stage, obtain the concentrated grosvenor's momordica fruit polysaccharide and trace elements.

Description

(1) Technical field [0001] The invention belongs to a process method for extracting sweet glycosides from Luo Han Guo. (2) Technical background [0002] Luo Han Guo is a well-known fruit with medicinal effects. The mogroside contained in it can be used as medicine or as a sweetener. The fructose and trace elements contained in it can be used as additives for health food. At present, the method used by people to extract the active ingredients in Luo Han Guo is mainly to extract with water or alkaline water, and the filtrate is concentrated and dried to obtain the product. The active ingredient extraction rate in Luo Han Guo is low like this, and the product composition of gained is complicated. [0003] There are also some patent applications for research on the extraction method of active ingredients of Luo Han Guo, such as Chinese invention patent application 87101850 "Extraction method of sweetener from Luo Han Guo", and Chinese invention patent application 02113548.7 "Me...
