Description
Technical field
The present invention relates to technical field of plant extraction, especially a kind of preparation method of extract of Grosvenor Momordica comprehensive utilization.
Background technology
The Grosvenor Momordica nutritive value is very high, contain the Grosvenor Momordica glucoside, contain in addition glucose, fructose, polysaccharide, protein, amino acid, flavonoid glycosides, vitamins C and multiple mineral element, have flavor sweet cool in nature, return lung, large intestine channel, moisten the lung and relieve the cough, the effect that promotes the production of body fluid to quench thirst, be applicable to lung heat or xeropulmonary cough, it is thirsty etc. that Whooping cough and hot summer weather are hindered Tianjin, the effect that relaxes bowel in addition in addition.The Grosvenor Momordica deep processing is mainly to extract the Grosvenor Momordica glucoside, in the process of extracting the Grosvenor Momordica glucoside, also contains abundant nutritive substance in the Grosvenor Momordica extracting solution that abandons, and such as momordica grosvenori polysaccharide, is a kind of bioactive ingredients that strengthens body immunity that has.The Chinese invention patent application publication number is CN101007042A, and name is called the Fructus Monordicae extract preparation method of a kind of decolouring, debitterize, discloses a kind of decolouring, debitterize, contains the method for preparing extractive of Grosvenor Momordica glucoside; This method is after extracting the Grosvenor Momordica glucoside, and the Grosvenor Momordica extracting solution can also reclaim, and further extracts the composition that contains momordica grosvenori polysaccharide, obtains a kind of nutritious Fructus Monordicae extract, can be used as the raw material of healthcare products, nutritious prod.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of preparation method who reclaims, extracts the extract that contains momordica grosvenori polysaccharide from extract the extracting solution that the Grosvenor Momordica glucoside abandons later on, can access by the method that a kind of solvability is good, cost is low, be convenient to the further Fructus Monordicae extract that contains momordica grosvenori polysaccharide of processing.
Technical scheme of the present invention is: a kind of preparation method who contains the extract of momordica grosvenori polysaccharide, take dried fructus momordicae as raw material, the employing pure water extracts, concentrated, the column chromatography decoloration and deodorization, reclaim liquid enzymolysis, decolouring, filtration, micro-filtration, nanofiltration, drying obtain containing the Fructus Monordicae extract of momordica grosvenori polysaccharide.
Described pure water extracts, refer to the pure water that Grosvenor Momordica first is placed in 6 times of its weight is decocted and obtain arhat pomace and water extraction liquid A, then the pure water that the arhat pomace is placed in 8 times of its weight is decocted obtain water extraction liquid B, A and B are merged, filter, obtain just extract of Grosvenor Momordica.
Described recovery liquid enzymolysis, decolouring, refer to after Grosvenor Momordica concentrated solution process macroporous resin adsorption, extraction Grosvenor Momordica glucoside material, recovery contains the concentrated solution of momordica grosvenori polysaccharide, then add by weight proportion the polygalacturonase of 0.01-0.02%, the papoid of 0.05-0.4% stirs, controlling temperature is 40-55 ℃, after 20-30 minute, then add the gac of 1.0%-2.0%, kept 30-60 minute.
Described filtration can be Plate Filtration, obtains cleaner liquid, crosses cleaner liquid and adopts instantaneous ultra high temperature sterilization (UHT) sterilization, and sterilization temperature is controlled at 121-125 ℃.
Described micro-filtration preferred film aperture is the microfiltration membrane of 0.45 μ m; Obtain the filtrate by microfiltration membrane; When selecting membrane pore size to be the microfiltration membrane of 0.22 μ m, in filtrate, momordica grosvenori polysaccharide content reduces, and has been trapped part.
Described nanofiltration refers to the filtrate by microfiltration membrane is passed through nanofiltration membrane at normal temperatures, plays under normal temperature concentrating, and obtains the nanofiltration concentrated solution;
Described drying can be spraying drying, lyophilize or other drying meanss, will obtain getting nanofiltration concentrated solution drying, perhaps further pulverizes, and obtains containing the Fructus Monordicae extract of momordica grosvenori polysaccharide.
Described Grosvenor Momordica pure water extracts, and is concentrated, and the column chromatography decoloration and deodorization filters, the UHT sterilization, and micro-filtration, nanofiltration, drying is all known technology.
The present invention has following advantages and characteristic:
1, comprehensive utilization of resources.With extracting the later Grosvenor Momordica extracting solution recycling of Grosvenor Momordica glucoside material, obtain a kind of extract that contains momordica grosvenori polysaccharide, can further be processed into various nutritious prod and healthcare products, the Grosvenor Momordica resource has obtained comprehensive utilization.
2, combination technique is novel.After recovery contains the concentrated solution of momordica grosvenori polysaccharide, add polygalacturonase and papoid, depolymerized pectin and the protein-based macromolecular substance that waits can reduce concentrated solution viscosity, lay the first stone smoothly for follow-up nanofiltration operates, and can also improve the solubleness of extract.The gac that adds, main purpose are decolourings, guarantee that the extract color that obtains is faint yellow, is convenient to further be processed into other healthcare products, nutritious prod.Crossing the sterilization of cleaner liquid employing instantaneous ultra high temperature sterilization (UHT) is for killing bacteria and the polygalacturonase, the papoid that add, is convenient to follow-up link quality stable.The preferred film aperture is that the microfiltration membrane of 0.45 μ m is for removal of impurities, clarification, is convenient to the nanofiltration membrane operation, increases the service life, and can also reduce holding back and losing of momordica grosvenori polysaccharide as far as possible.Selecting nanofiltration membrane is for concentrated at normal temperatures, ensures the quality of products, and reduces costs.These technical combinations are supported mutually together, and acting in conjunction can obtain just that solvability is good, cost is low, contain the extract of momordica grosvenori polysaccharide.
