Abstract
The invention discloses a process of extracting pectin from snake gourd peel. The process includes: using the snake gourd peel as a raw material; subjecting the snake gourd peel to cleaning, soaking, crushing, juice removing, paste centrifuging, concentrating and drying sequentially to obtain snake gourd peel pectin. Two processes of acid hydrolysis and ball milling are combined, chemical action and mechanical force action are performed at the same time, and high temperature generated in the process of smashing deactivates enzymes in the snake gourd peel; due to tissue micronization, acid hydrolysis of fiber in the snake gourd peel is promoted, acid hydrolysis dissolution of pectin substance is facilitated, extraction efficiency is improved, extraction time is reduced, pectin extraction rate is high, and an obtained product is high in purity and good in appearance.
Description
Technical field
The present invention relates to Fructus Trichosanthis applied technical field, be specifically related to a kind of extraction fruit from Pericarpium Trichosanthis
The technique of glue.
Background technology
Pectin is one group of polygalacturonic acid, and molecular weight about 5-30 ten thousand is primarily present in plant
Cell wall and cell internal layer, for the support substance of internal cell.Food is made gellant,

To protection skin, placing ultraviolet radiation, treat wound, all there is certain effect in beautifying.
Fructus Trichosanthis belongs to cucurbitaceous plant." detailed outline " is recorded: lung moistening is dry, pathogenic fire reducing.Control cough, wash
Expectorant is tied, throat, subduing inflammation sore.Fructus Trichosanthis root is the Chinese crude drug of a kind of medicine-food two-purpose, has
The highest nutrition and medical value.Pericarpium Trichosanthis usually people abandon skin when eating Fructus Trichosanthis, particularly seed
After melon takes seed, remaining abandons in the lump, there is serious waste, and causes surrounding enviroment sternly
The impact of weight.Therefore the comprehensive processing and utilization of Pericarpium Trichosanthis, is a problem anxious to be resolved.
Summary of the invention
It is desirable to provide a kind of technique extracting pectin from Pericarpium Trichosanthis.
The present invention provides following technical scheme:
A kind of technique extracting pectin from Pericarpium Trichosanthis, comprises the following steps:
(1) select the fresh Pericarpium Trichosanthis without corruption, clean and remove earth, Pericarpium Trichosanthis is immersed in carbon
In acid calcium saturated aqueous solution 24 hours, pull afterflush out clean, then orange peel is cut into 5mm
The square fragment of left and right, puts into immersion 30-40min in the ethanol that volume fraction is 70%, subtracts
Pressure rotary evaporation removes ethanol；
(2) Pericarpium Trichosanthis that step (1) obtains is irradiated 15-30min under ultraviolet light, send
In entering expeller, Pericarpium Trichosanthis is blended juice, add the water of filtering residue weight in wet base 1-2 times, clearly
Wash, cross elimination juice；
(3) by gained raw material in step (2), by weight the water of addition 3-4 times, with food
Adjust pH to 1.5-2.0 with vinegar regulation, be placed in waterproof pulverization 1-1.5h in ball mill and obtain Fructus Trichosanthis
Skin juice, is incubated 30-40min, filters, obtains serosity and filtering residue；
(4) again by the filtering residue in above-mentioned steps (3) adds the water of 2-3 times of volume, add edible
Vinegar adjusts pH to 2.0-3.0, heated and boiled 20-30min, filters and collects serosity；
(5) serosity that serosity step (3) obtained and step (4) obtain exists
Under the conditions of 6000-8000rpm, centrifugal 15-20min, obtains supernatant；
(6) activated carbon of the 0.5% of addition supernatant gross weight in supernatant, at 60-72
Decolour under the conditions of DEG C 30min, filters, then reduces pressure and carry out membrance concentration to substance by tubular membrane
Long-pending 15-18%, obtains concentrated solution, is released by concentrated solution and be rapidly cooled to 4 DEG C；
(7) in concentrated solution, add the ethanol of 90% with the volume of 1:1, stir while adding
Uniformly, then stand 3-4 hour, vacuum filtration, reclaim filtrate, the filter cake obtained is with 90
The washing with alcohol of %, reclaims ethanol, is pulverized by filter cake and is dried 2-3h at 50 DEG C, to obtain final product
Pectin powder.
In described step (2), the rotating speed of ball mill is 250-400rpm.
In described step (2), ball mill is planetary ball mill.
Compared with prior art, the invention has the beneficial effects as follows: present invention incorporates acid hydrolysis,
2 processes of ball milling powder, chemical action and mechanical force carry out simultaneously, and crushing process produces
High temperature makes the enzyme classes in Pericarpium Trichosanthis inactivate, and additionally, due to the granular of tissue, promotes Fructus Trichosanthis
The acid hydrolysis dissolution of the acid hydrolysis of fiber, beneficially pectin substance in skin, improves extraction efficiency,
Shortening extraction time, the extraction ratio of pectin is high, and products obtained therefrom purity is high, and outward appearance is good.
