Abstract
The invention discloses a production process of high-purity solid phytic acid. Degreased rice bran or corn meal is adopted, hydrochloric acid is used for soaking and leaching filtrate, filtering is carried out after NaOH or KOH is used for adjusting the pH value, and high-purity solid phytic acid is obtained by virtue of an anion exchange column, a cation exchange column and crystallization. According to the production process disclosed by the invention, technological innovation is realized, the purity of the prepared phytic acid can be up to more than 98%, and the problem that liquid phytic acid is darkened in a storage process can be effectively solved. The solid phytic acid produced by virtue of the production process is high in purity and white in colour, contains less impurities and is one of good additives in the food industry, and the solid phytic acid product has good oxidation resistance and is safe and non-toxic, so that the solid phytic acid is widely used as food preservative and antiseptic.
Description
Technical field
The present invention relates to a kind of manufacture method of foodstuff additive, specifically refer to a kind of high-purity solid phytic acid production technique.
Background technology
Phytic acid is that a kind of important organophosphorus is additive, has unique physiological function and chemical property, has widespread use at aspects such as food, medicine, daily-use chemical industry, metal processing, textile industry, Polymeric Industry and plastic working industry.
In view of phytic acid has been widely used and higher economic worth, the research and development dynamics is all being strengthened in countries in the world.The phytic acid of selling on the market now mostly is greatly liquid phytic acid, and the liquid phytic acid of pure natural is difficult for storing.The liquid phytic acid the inside exists the materials such as protein, polysaccharide, natural pigment, potential pigment, iron ion so that phytic acid color and luster in storage process affects phytic acid outward appearance and application by the faint yellow Vandyke brown that becomes.Solid phytic acid purity is high, can not variable color, be convenient to store, convenient transportation, be the preferred product in following phytic acid market.
That high-purity solid phytic acid has solved is easy to change in the liquid phytic acid storage process, transportation inconvenience and the not high defective of purity.And liquid phytic acid very difficult application inside oil, solid phytic acid has solved this problem.Because phytic acid is to extract from natural rice bran, corn, so this product is nontoxic.Phytic acid is low as its addition of foodstuff additive, and the effect but additive than general chemosynthesis is good, therefore can replace the foodstuff additive of some chemosynthesis to be widely used in foodstuffs industry.Solid phytic acid is soluble in water, and the client can oneself allocate concentration and addition according to the variant production needs.
Summary of the invention
The present invention is in order to remedy the deficiency of existing air filter, a kind of high-purity solid phytic acid production technique is provided, has solved liquid phytic acid and in storage process, held allochroic problem, and improved greatly the purity of phytic acid, the convenient storage transported, and reduced transportation cost.
A kind of high-purity solid phytic acid production technique of the present invention is achieved through the following technical solutions:
A kind of high-purity solid phytic acid production technique may further comprise the steps successively:
(1) defatted rice bran or the corn dregs of rice are adjusted pH value to 3 with 6% hydrochloric acid, soak and quench 6-8 hour, and filtrate adds lime slurry neutralization, regulate pH value to 6 ~ 6.5 with NaOH, filter, abandon filtrate, and filter residue is phytin sodium crude product;
(2) in the water of phytin sodium crude product adding 6-10 doubly being measured, adjust pH value to 2.5 with hydrochloric acid soln, treat to dissolve fully, add activated carbon decolorizing filtration, desugar; Filtrate adds NaOH and adjusts the pH value to 3-4.5, separates out albumen, adopts filter method to separate and separates out albumen, gets filtrate;
(3) gained filtrate is advanced the exchange of weakly-basic anion exchange column, washing; Then use 4-8% alkali lye wash-out; Elutriant is adjusted the pH value to 12-14 with 4-8%NaOH or KOH solution, and sediment separate out contains iron ion in the throw out;
(4) liquid after the separation is crossed the cationic exchange coloum exchange, and effluent liquid advances macroporous anion exchange resin chromatography column chromatography, and it is concentrated that chromatographic solution advances upgrading tower, is concentrated to phytic acid content 50-70%, and concentrated solution adds activated carbon decolorizing, filters, and gets filtrate;
(5) liquid end product phytic acid: liquid phytic acid is concentrated into proportion 1.390, and adjusting pH value is 2, then puts into crystallizer and clarifies;
(6) overcritical stable: it is stable that liquid phytic acid is placed in the crystallizer clarification;
(7) alcohol wash-out: put into the alcohol washing in the liquid phytic acid, destroy the heteropolar bond of phytic acid and water, under the whipped state, decrease temperature crystalline leaches crystal, and is repeated multiple times, obtains the crystallization phytic acid.
As preferably, described alkali lye refers to NaOH or KOH solution.
As preferably, described gac dosage is 3 ~ 5%.
Compared with prior art, the beneficial effect of a kind of high-purity solid phytic acid production technique of the present invention is: can effectively solve the problem that liquid phytic acid darkens in storage process.The solid phytic acid purity of this explained hereafter is high, few, the white color of impurity, is one of additive good in the foodstuffs industry, and this product has good oxidation-resistance, and safety non-toxic, therefore is widely used as food preservative and sanitas.
Embodiment
Below by embodiment and the prescription the present invention is specifically described, the present invention includes, but be not limited to following listed embodiment.
Process program: defatted rice bran or the corn dregs of rice are adjusted pH value to 3 with 6% hydrochloric acid, soak and quench 6-8 hour, and filtrate adds lime slurry neutralization, regulate pH value to 6 ~ 6.5 with NaOH, filter, abandon filtrate, and filter residue is phytin sodium crude product; Phytin sodium crude product is added in the water of 8 times of amounts, adjust pH value to 2.5 with hydrochloric acid soln, treat to dissolve fully, add 4% activated carbon decolorizing filtration, desugar; Filtrate adds NaOH and adjusts the pH value to 3-4.5, separates out albumen, adopts filter method to separate and separates out albumen, gets filtrate;
