Description
Technical field
The present invention relates to Momordica grosvenori, specifically is a kind of technology that adopts membrane separation technique to prepare the fresh fructus momordicae concentrate.
Background technology
Momordica grosvenori (formal name used at school: Siraitia grosvenorii swingle); It is Curcurbitaceae Momordica grosvenori platymiscium; Being one of first batch of medicine food dual purpose plant of announcing of health ministry, is the famous and precious raw material of pharmacy and food industry, has very high nutritive value and economic worth.With the bright cream that fresh fructus momordicae is produced, have clearing heat and moistening lung, relieving cough and reducing sputum, relax bowel, hypotensive, reducing blood lipid, protect the liver effects such as transaminase lowering; With the beverage that bright cream is made, have and fire one's imagination and unique fresh and sweet local flavor; Bright cream can be as producing various functional beverages and food additives.
The patent application that also has at present some researchs to extract fresh fructus momordicae juice; Mainly be to extract with traditional method: like Chinese invention patent application CN1181908 " a kind of fresh grosvenor momordica concentrated solution production technology " is fresh fructus momordicae to be added citric acid transfer the fruit juice pH value to 3-4 behind thermophilic digestion; Add complex enzyme again and make the suspension deposition in the fruit juice; Through the plate and frame diatomite filtration, after concentration pan concentrate fresh fructus momordicae juice.These methods all are to adopt traditional methods such as diatomite filtration, plate-frame filtering method, fining agent method, alcohol deposition method, the enzymolysis precipitation method and other biochemistry to produce, and these technologies can't also exist like filtration difficulty to be prone to stop up to the separation effectively of various compositions, purifying and the clarification of fresh fructus momordicae leachate simultaneously; The alcohol deposition method solvent consumption is big, and the enzymolysis precipitation method and other biochemical process all have foreign substance to add, and product purity is not high; Yield is low, complex process, and equipment investment is big; The fresh fructus momordicae concentrate product of gained is prone to produce deposition; Produce when extracting, wastewater flow rate is big, contaminated environment.
Summary of the invention
The purpose of this invention is to provide a kind of technology that adopts membrane separation technique to prepare the fresh fructus momordicae concentrate.This process products obtained therefrom purity is high, the clarity of product, light transmittance, good stability, and operating environment is gentle, and energy consumption is low, and equipment is simple, small investment; Need not add any chemical reagent, free from environmental pollution, and kept the active components of plants of product to greatest extent.
The technical scheme that realizes the object of the invention is:
A kind of technology that adopts membrane separation technique to prepare the fresh fructus momordicae concentrate comprises the steps:
(1) choosing fruit, wash fruit: choose the big or middle fresh fructus momordicae of high-quality, and fresh fructus momordicae is clean, broken;
(2) steeped 6-16 hour with 40-95 ℃ water logging, 3-5 time repeatedly, the weight ratio of Momordica grosvenori and water is 1 ︰ 3-4;
(3) leachate is after 60-250 purpose bag filter filters, and sends into integrated film system through compression pump order under the 0.05-3.0MPa operating pressure, under full closeding state, separates, purifying, is concentrated into the 16-35 Baume degrees.
Described integrated film system is made up of the following film spare of arranging in regular turn:
(1) elementary micro-filtration membrane part, i.e. ceramic composite membrane: hold back suspension, particulate and the assorted bacterium of isolating in the feed liquid;
(2) two-stage ultrafiltering film: hold back macromolecular substances such as isolating albumen, colloid, fiber;
(3) ultimate reverse osmosis membrane: finally realize separating of fresh fructus momordicae composition and water, become the higher fresh fructus momordicae concentrate of concentration.
Advantage of the present invention is:
1. different the filtration between the rank has the independent operation unit of one's own, and separation, purifying, a concentrated step accomplish, and technology is simple, and energy consumption is low, and equipment investment is few.
2. separation, purifying, easy, easy to operate, the easy automatic control of enrichment facility; Product separates to be concentrated in full closeding state under and moves, and has reduced that oxygen has kept the vegetable active composition of fresh fructus momordicae concentrate preferably to the influence of product in contamination of products and the air.
3. the clarity of product, light transmittance, good stability, yield is high, and purity is high.
4. do not add any chemical reagent, free from environmental pollution, product is of high nutritive value, environmental protection.Can reach the 16-35 Baume degrees as required through separation, purifying, concentrated fresh fructus momordicae concentrate concentration.
Description of drawings
Fig. 1 is the FB(flow block) of technology of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further elaboration.
With reference to Fig. 1, a kind of technology that adopts membrane separation technique to prepare the fresh fructus momordicae concentrate comprises the steps:
