Abstract
The present invention relates to a kind of is the pectin preparation method of raw material with the beet pulp, and it is made optimal selection to the pH value and the temperature control value of acid extraction liquid, and the beet pulp raw material is optimized pre-treatment on the basis of traditional acid-hydrolysis method and ion natural gum exchange process.This method simple possible, be easy to promote, use the productive rate of its pectin of obtaining through refining and degree of gelation compared with prior art all to improve a lot.
Description
The present invention relates to a kind of additive preparation technology, belong to the comprehensive utilization of natural phant.
Pectin is a kind of polyose hydrocarbon polymer, and its main chemical is polygalacturonic acid and a spot of neutral sugar, L-arabinose and semi-lactosi etc., is the important source material of producing jam, jelly, makeup, emulsifying agent and dewatering agent.
Pectin content is about 15～20% in the beet pulp (doing), is a kind of ideal natural matter that is used to produce pectin.The method of producing pectin with beet pulp is generally acid-hydrolysis method and ion-exchange resin etc., but select discomfort, raw material without defectives such as pre-treatment or pretreatment mode are improper owing to still have the pH value (generally being 4～5) of acid extraction liquid and temperature control value (generally being 60～80 ℃) in the traditional technology, cause its productive rate of producing pectin and degree of gelation all very low.
Task of the present invention is on above-mentioned traditional technology basis, and its preparation method is done further rationally to improve, and overcoming the deficiencies in the prior art part, and improves productive rate and degree of gelation that beet pulp is produced pectin.
Accompanying drawing 1 is a preparation method's of the present invention process flow sheet, its concrete steps comprise raw material crushing, pre-treatment, water treatment, the acid hydrolysis extraction of beet pulp, coarse filtration, ammoniacal liquor neutralization, smart filtration, resin impurity elimination, vacuum concentration, alcohol precipitation, drying, pulverizing and pack etc.Below will be selected and to be narrated it.
1. the fragmentation of raw material: generally beet pulp is broken into the small-particle of 2～4mm, if particle is too little, can makes the vat liquor filtration difficulty, particle is too big, can cause the pectin extraction yield to descend again.
2. raw materials pretreatment: pectin is divided into water soluble pectin and insoluble pectin two classes, and can be divided into hexa metaphosphoric acid soluble pectin and hydrochloric acid soluble pectin in insoluble pectin.Former pectin has only extracted the hydrochloric acid soluble pectin in extracting, and about 50% hexa metaphosphoric acid soluble pectin fails to obtain to extract, so productive rate is low, the cost height.In order to extract hydrochloric acid and hexa metaphosphoric acid soluble pectin simultaneously, planner of the present invention makes the hexa metaphosphoric acid soluble pectin change into the hydrochloric acid soluble pectin by beet pulp being carried out pretreated process, its specific practice is that beet pulp is immersed in the hydrochloric acid soln that controlled temperature is 0.02～0.06N below 30～40 ℃, and soak time is 15～20 minutes.If concentration of hydrochloric acid is lower than 0.02N, just can not make the hexa metaphosphoric acid soluble pectin be converted into the hydrochloric acid soluble pectin, concentration can make the fat degree of pectin descend again greater than 0.06N.In addition, also can remove carbohydrate, organic acid and pigment in the beet pulp by pre-treatment.
3. water treatment: ortho-water generally contains more calcium, magnesium ion, because these ion pair protopectin-have sealing process, make it be difficult to be converted into water soluble pectin, and pectin grade is greatly reduced, consider from economic benefit for this reason, can in water, add 0.5% Sodium hexametaphosphate 99 or 0.5% tripoly phosphate sodium STPP, make calcium, magnesium ion in it and the water form complex compound.
4. acid hydrolysis extraction: beet pulp and water are inserted extraction kettle in 1: 30 ratio, add the hydrochloric acid soln of 6N, regulating PH is between 1.2～1.8, the control extraction temperature is between 90～95 ℃, and coarse filtration is carried out in hydrolysis extraction 1 hour then, remove residue, collect filtered liquid.
5. ammoniacal liquor neutralization: filtered liquid is 4～5 with the ammoniacal liquor regulator solution PH of 4N.
6. smart the filtration: make flocculating aids and discoloring agent decolours with diatomite, the liquid pectin that obtains is limpid transparent like this, and quality is good.
7. resin impurity elimination: the solution after the essence filter is heated between 60～70 ℃, and the ion exchange resin column by handling well can be removed impurity such as metal ion while hot.
8. vacuum concentration: the pectin that will filter after the impurity elimination is poured in the vacuum distillation plant, and carrying out vacuum concentration to concentration about 60 ℃ is 5%.Or send in the wiped film evaporator liquid pectin of filtering concentrated.The liquid pectin heated time is short, and temperature is low, can operate continuously.
9. alcohol precipitation: the pectin after will concentrating cools off rapidly, and it is flowed in the alcohol that contains 0.5M hydrochloric acid equably with multiply fine rule stream shape, and pectin is precipitated fully, and the concentration of alcohol is controlled at about 50% and is advisable.The pectin throw out just can carry out press filtration after placing 3～4 hours, simultaneously again with 95% alcohol washing secondary, and removal of contamination, raising product purity.
10. dry: the pectin controlled temperature after the press filtration is carrying out drying below 60 ℃, reduces to 7% taking-up when following to water content and pulverizes immediately, sieves, packs.
Compared with prior art, the method for the invention is simple, is convenient to promote, and measures through relevant single-unit, and the pectin productive rate of obtaining through refining with this method is 14～18%, and degree of gelation is more than 140 grades, and the contrast prior art all improves a lot.
In addition, will obtain the pectin of high gel strength usually, raw material should be with fresh beet pulp for well, but if can't all utilize in a short time, just must consider the preservation of beet pulp, is beneficial to long-run equilibrium production.The invention provides a kind of beet pulp store method of producing pectin technology that is exclusively used in, the beet pulp after the sugar that is about to squeeze out mixes mutually with slaked lime, makes water soluble pectin be transformed into insoluble calcium phosphate and preserves.In addition, also available oven drying method and salt salt marsh method are preserved beet pulp.
