Abstract
The invention relates to a method for preparing crystalline maltitol. The method comprises steps that: starch milk is adopted as a raw material, and is liquefied and saccharified with an enzymic method, such that maltose is prepared; maltose is separated and purified, and high-purity maltitol is prepared through hydrogenation; the high-purity maltitol is purified, crystallized, and packaged; part of crystallization mother liquor is refluxed into a concentration and crystallization process, such that the crystallization yield is improved; part of the crystallization mother liquor is discharged from the system for preventing impurities from accumulating. Discharged mother liquor is processed through ion exchange, and maltitol is recovered through chromatographic fractionation. Separated impurities are condensed, and are adopted as common maltitol.
Description
Technical field
The present invention relates to biological field, particularly a kind of method for preparing crystal maltitol.
Background technology
Producing crystal maltitol is to make raw material with milk of starch, and through the enzyme process starch-splitting, acquisition contains monobasic sugar, binary sugar (SANMALT-S), ternary is sugared, quaternary is sugared, the mixed solution of five yuan of sugar.Other sugar all has bigger influence to the crystallization of binary sugar alcohol.Separation is purified and is obtained high-purity SANMALT-S, not only can reduce the hydrogenant hydrogen consumption, mainly is the feed liquid that can obtain crystallization requirement purity, and therefore separating purification is the key of technology.Existing separation method has chromatography and nanofiltration separation method, and chromatography requires the concentration of charging dry about 60%.
The maltose alcohol working method has spray-drying process and crystallization process, and the former product particle is thin, and impurity is many, and market price is low, and spray-dired energy consumption is big; The purity of latter's crystalline product is high, and market price is high, and energy consumption is low.
This process using industrial chromatography tripping device separates the sugar that removes more than the binary, adopts chromatographic separation to reclaim the maltose alcohol of mother liquor, and obtains product with crystallization method.
Summary of the invention
The working method of crystal maltitol of the present invention is to be raw material with the milk of starch, makes SANMALT-S through the enzymatic liquefaction saccharification, after separation is purified; Hydrogenation obtains the maltose alcohol of high density; Purify again post crystallization, drying, packing, the partial crystallization mother liquor is back to the condensing crystal operation, to improve crystallization yield; Part discharge system prevents impurities accumulation.The mother liquor of discharging discolors and composes the Separation and Recovery maltose alcohol through after handing over, and the impurity of separating concentrates the back as common maltose alcohol.
Isolated ternary of SANMALT-S and above sugar are transformed syrupy product through decolouring, concentrate, filtering promptly in the acquisition.
Embodiment:
(1) adopt efficient Ye Huamei and the efficient hydrojet well heater of the U.S., can make liquefaction more thorough, not only shorten heated time, practice thrift steam, what is more important can be opened the transient structure of starch molecule effectively, helps liquefaction, saccharification.
(2) syrup filtration employing is that flocculating aids is accomplished through vacuum suction filter with zeyssatite.
(3) continuously from handing over desalination, than conventional fixed bed ion-exchange unit higher working efficiency is arranged, resin consumption is merely about the 1/4-1/2 of fixed bed, and wastewater flow rate be merely its about 1/3, takes up an area of also very for a short time, significantly reduce and invest and working cost.
(4) change the mode of operation of using the single-column chromatographic separation always; Periodical operation is become operate continuously; Make each section chromatographic column in running order all the time; Improve the working efficiency of chromatographic column, reduced the consumption of eluent, also significantly reduced the fluctuation of the input and the quality product that human factor causes of personnel's work.Four-column type modified version ISMB The Application of Technology had both improved the quality of product, had also reduced production cost.
(5) wastewater membrane is handled.In the production process, regeneration of resin will produce the waste water that much contains inorganic salt, and this part waste water cannot directly discharge, in order to avoid environment is polluted, biochemical treatment is had any problem (lacking C, the utilization of N source confession mikrobe) separately.This engineering utilization RO membrane technique is handled this part waste water, and it sees through liquid and can return as vaal water, and trapped fluid gets into the biochemical treatment station with starch wastewater.
The secondary steam of the evaporation concentration in the production process and in the preface of handing over reclaims, contain sugar part, this part waste water is handled through the RO film, vaal water returns in the technology and uses, simultaneously waste water contain sugared recyclable, reduce raw material sugar and consume.
(6) whole-process automatic control.Technology chain of the present invention is longer, and the fluctuation of processing condition has a strong impact on generation to reaction process, and omnidistance enforcement of technology controlled automatically; Reduce the human factor influence; Guarantee that production process is in the optimised process reference mark all the time,, improved technical guarantee for improving the quality of products and yield.
Claims (3)
1. a method for preparing crystal maltitol is characterized in that adopting the efficient hydrojet well heater of the efficient Ye Huamei and the U.S., can make liquefaction more thorough, more can open the transient structure of starch molecule effectively, helps liquefaction, saccharification.
2. a kind of method for preparing crystal maltitol as claimed in claim 1 is characterized in that it is that flocculating aids is accomplished through vacuum suction filter with zeyssatite that syrup filters employing.
3. a kind of method for preparing crystal maltitol as claimed in claim 1 is characterized in that changing the mode of operation of using the single-column chromatographic separation always, and periodical operation is become operate continuously, makes each section chromatographic column in running order all the time.
