Abstract
The invention discloses a glucolactone producing method, adopting Aspergillus Niger M290 to ferment amylum hydrolysate of the sugar, carrying out the steps of culturing seed, fermenting, eliminating thallus, decolorizing, eliminating calcium by ion-exchange, condensing, crystallizing, drying, etc, to firstly convert the amylum hydrolysate of the sugar into calcium gluconate, then eliminate the Ca-ion by ion-exchange resin to convert into gluconic acid, and then condensing and crystallizing to produce the glucolactone.
Description
Technical field
The present invention relates to a kind of production method of glucolactone, particularly adopt the fermentation of Aspergillus niger amylum hydrolysate of the sugar, generate calglucon earlier, produce the method for Gluconolactone again through the Zeo-karb decalcification.
Background technology
Gluconolactone be glucono delta lactone (abbreviation of Glucono-δ-lactone), outward appearance is white crystal or crystalline powder, is slightly soluble in ethanol, very easily water-soluble, hydrolysis is slow under room temperature or the lesser temps, and along with the rising of temperature, hydrolysis rate is accelerated.Glucono delta lactone is the nontoxic foodstuff additive of generally acknowledging in the world at present, can be used for making the peptizer of bean curd, makes the raising agent of bread, makes the souring agent and the sanitas of cheese class, makes the toner of sausage ham.Also can be used as industrial additive, be used for preparing clean-out system, add toothpaste and help to remove tartar, be used for the generation that milk industry prevents mammary calculus, be used for the generation that brewery industry prevents beer scale, and as the pH depressant etc.
Mainly contain two kinds of methods with glucose for the raw material production Gluconolactone: a kind of is to adopt enzyme process and electrochemical process, with the direct catalyzed oxidation of glucose is Gluconolactone, present method transformation efficiency is low, reaction control difficulty, and the making step of catalyzer is loaded down with trivial details, this method is only limited to the laboratory study stage at present, successfully is not used for suitability for industrialized production.Another kind method is to produce Gluconolactone by gluconate.Present method is divided microbe fermentation method and air catalytic oxidation method again.Catalyst metal palladium source difficulty in the air catalytic oxidation method, method for preparing catalyst requires high, thereby the air catalytic oxidation method is not used widely.Microbe fermentation method, because the transformation efficiency height, production cost is lower, is easy to carry out suitability for industrialized production, thereby microbe fermentation method is mainly adopted in the production of Gluconolactone at present.
Microbe fermentation method is divided into calcium salt method and sodium salt method.In the calcium salt method, earlier glucose is converted into calglucon through the gluconic acid that microbial fermentation generates, crystallization goes out calglucon from fermented liquid through concentrating again, then with calglucon through the acidifying decalcification, calcium ion is removed in ion-exchange, and last condensing crystal is separated out Gluconolactone.In the sodium salt method, earlier gluconic acid is converted into sodium salt, removes sodium ion through ion-exchange again, last condensing crystal is separated out Gluconolactone.
In the above-mentioned calcium salt method, fermented liquid earlier generates calglucon through condensing crystal, acidifying decalcification again, and sulfuric acid is used in the acidifying decalcification, and temperature of reaction is up to 100 ℃, and to the equipment requirements height, and fermented liquid will concentrate through twice, just can obtain Gluconolactone, the energy consumption height.The sodium salt method is low at calglucon solubleness in the calcium salt method, can not carry out the problem of high sugar-fermenting, add the sodium hydroxide of high density during the fermentation, the pH value of control fermented liquid, the fermentation later stage is added glucose, carries out high sugar-fermenting, and this method adopts stream to add fermentation, and the interpolation high-concentration sodium hydroxide is to equipment and operational requirement height, easily microbiological contamination.
Summary of the invention
At the problem that exists in above-mentioned calcium salt method and the sodium salt method, the present invention adopts the fermentation of Aspergillus niger amylum hydrolysate of the sugar, generate calglucon earlier, remove calcium ion through Zeo-karb again, save steps such as calglucon condensing crystal and acidifying decalcification, thereby reach the purpose of simplifying technological operation and cutting down the consumption of energy.
The present invention adopts aspergillus niger M290 fermentation amylum hydrolysate of the sugar, through seed culture, fermentation, remove thalline, decolouring, ion-exchange decalcification, concentrate, crystallization and drying and other steps, with amylum hydrolysate of the sugar, be converted into calglucon earlier, remove calcium ion through ion exchange resin again, be converted into gluconic acid, condensing crystal generates Gluconolactone then.Step of the present invention is as follows:
1. seed liquor is cultivated:

3. remove thalline
Put a jar filtration sterilization body.
4. decolouring
Adding weight ratio and be 2% gac boils and decolours the centrifugal again gac of removing.
5. cationic exchange is removed calcium ion
To remove calcium ion through Zeo-karb through the fermented liquid of decolouring.
6. condensing crystal:
To 1/5th of original volume, put into crystallizer adding weight ratio is the crystal seed of 0.1～0.2% Gluconolactone to deionization liquid, 48 ℃～52 ℃ following stirred crystallization at 80 ℃ of following vacuum concentration.
7. the whizzer centrifuge dehydration is put in the gained crystallization, with a small amount of cold water washing three times, in 60 ℃ of oven dry, promptly gets Gluconolactone then.Centrifuge dehydration liquid and three washingss merge, the reconcentration crystallization once, to improve the yield of Gluconolactone.
