Definitions
- the present invention relates to a method of high crystalline anhydrous dextrose ⁇ preparation purity from a starch hydrolyzate.
- the invention relates to a process for the preparation of an anhydrous crystalline dextrose which consists in subjecting a starch hydrolyzate to a nanofiltration to prepare a syrup with high content glucose, then evaporate the syrup of glucose thus obtained to obtain crystals of high purity anhydrous dextrose ⁇ .
- Dextrose can come in three forms crystalline, hydrated form or ⁇ monohydrate form, and two anhydrous forms, i.e. ⁇ anhydrous and ⁇ anhydrous.
- Solid dextrose is conventionally produced by crystallization of supersaturated syrups with a high content of glucose, and the crystals collected are crystals of dextrose ⁇ monohydrate. This process is also described in US Patent 3,039,935.
- Anhydrous dextrose ⁇ is classically obtained by dissolving crystals of dextrose ⁇ monohydrate in water, then by crystallizing at temperatures between 60 and 65 ° C and in vacuum evapo-crystallization operating conditions carefully set.
- the crystalline dextroses obtained by these processes have a strong tendency to agglomerate, which makes handling all the more difficult. Their flow characteristics are otherwise particularly poor.
- the product obtained still has more than 50% of anhydrous ⁇ form with the anhydrous ⁇ form, and a content non-negligible amorphous structure.
- the first is to optimize the process of preparation of said starch hydrolyzate.
- the second solution consists in implementing a nanofiltration process which removes all traces of these superior PDs, as described in the request for Patent FR 2,762,616 of which the Applicant company is holder, or US patent 5,869,297.
- the invention therefore aims to remedy this situation, and to propose a process that responds better than those that already exist to the various constraints of the convenient.
- the Applicant company thus succeeded in bringing point a process for obtaining an anhydrous dextrose high purity crystalline from high syrup glucose content prepared by nanofiltration of a starch hydrolyzate.
- raw saccharified starch hydrolyzate a hydrolyzate starch free of insoluble matter and not undergone no purification treatment aimed at eliminating soluble matter (enzymes, proteins, amino acids, dyes, salts, ).
- the liquefaction stage is carried out in two sub-stages, the first consisting in heating, for a few minutes and at a temperature included between 105 and 108 ° C, starch milk in the presence of the enzyme (type THERMAMYL 120L sold by the company NOVO) and a calcium activator, the second consisting in heating the starch milk thus treated, to a temperature between 95 and 100 ° C for one to two hours.
- the enzyme type THERMAMYL 120L sold by the company NOVO
- a calcium activator the second consisting in heating the starch milk thus treated, to a temperature between 95 and 100 ° C for one to two hours.
- the starch milk is subjected liquefied by the action of a glucogenic enzyme, in particular chosen from the group consisting of amyloglucosidase, the glucoamylase or any other glucogenic enzyme.
- a glucogenic enzyme in particular chosen from the group consisting of amyloglucosidase, the glucoamylase or any other glucogenic enzyme.
- this debranching enzyme is isoamylase or pullulanase.
- the saccharification stage is carried out in conditions and in a manner known in themselves, during approximately 12 hours to no more than 24 hours, so as to obtain a final hydrolyzate with a richness of between 50%, preferably 75%, and 95% by weight.
- the enzymes used can be of origin bacterial or fungal.
- the hydrolyzate thus saccharified is then preferably filtered preferably by microfiltration on membranes so as to collect a permeate of microfiltration comprising the crude saccharified hydrolyzate and a microfiltration retentate.
- the conditions of this treatment are chosen to maintain activity saccharifying enzyme within the starch hydrolyzate saccharified. This is why, according to an embodiment preferred of the invention, the microfiltration of raw saccharified hydrolyzate at a lower temperature or equal to the enzyme inhibition temperature glucogenic (the enzyme of saccharification) and, advantageously, at a substantially equivalent temperature at the saccharification temperature. So if the saccharification temperature is between 50 ° C and 60 ° c, microfiltration must be carried out at a temperature between 50 ° C and 60 ° C.
- the microfiltration membrane used in the process according to the invention advantageously presents a porosity between 50 nm and 200 nm, said porosity preferably being of the order of 50 nm.

- a saccharification of at least part of the retentate of nanofiltration so as to obtain a retentate of saccharified nanofiltration.
- This saccharification secondary (with reference to primary saccharification intervening upstream of the microfiltration stage) is possible because throughout the process according to the invention, the necessary was made to maintain a saccharifying enzymatic activity within the hydrolyzate especially at the level of the saccharification stage in not inhibiting the glucogenic enzyme at the end of hydrolysis and at the microfiltration stage by working in temperature conditions similar to that of step of saccharification.
- At least part of the retentate is recycled nanofiltration upstream of the separation step by nanofiltration on membranes. More specifically, we mixes at least part of the nanofiltration retentate with microfiltration permeate to form a mixture which is then advantageously saccharified. This secondary saccharification (here before the stage of separation by nanofiltration on membranes) is carried out for a period such that the saccharified mixture presents a glucose richness of at most 80%, and preferably 75% by weight.
- This molecular sieving step can consist, for example, in a chromatographic separation step or in a separation step on membranes.
- the chromatographic fractionation step is carried out in a manner known per se, discontinuously or continuous (simulated moving bed), on adsorbents of the type cationic resins, or on strongly acidic zeolites, preferentially charged using alkaline ions or alkaline earth such as calcium or magnesium but more preferably using sodium ions.
- the chromatographic fractionation is carried out using the process and the apparatus described in the patent American US-A-4,422,881, of which the applicant company is holder.

- the resins are advantageously of homogeneous particle size and between 100 and 800 micrometers.
- the fraction enriched in glucose obtained at the outlet of the chromatography step can then be mixed with the syrup with high glucose content previously obtained.
- the following stages of the process according to the invention then consists in evapo-crystallizing the high glucose syrup thus obtained to obtain a high purity anhydrous ⁇ crystalline dextrose.
- the third step (c) of the process according to the invention therefore consists in concentrating the syrup at high glucose content in a dry matter of at least 70% in weight.
- This concentration step is carried out so known per se, for example by evaporation of water under vacuum at a temperature of the order of 70 ° C.
- the concentration of glucose-enriched syrup can reach a value of around 80% in M.S.
- crystallization is initiated by the addition of anhydrous dextrose ⁇ in concentrated glucose syrup and under agitation.
- spontaneous nucleation is carried out by any method known per se by a person skilled in the art, for example by shearing said concentrated solution.
- the fourth step (d) of the process according to the invention consists in continuing crystallization by evaporation and stirring of said concentrated syrup so as to obtain a crystalline mass containing at least 30% by weight of crystals.

- the evapo-crystallization is carried out in a rotary evaporator where a relatively high vacuum is established, of the order of 6.67 10 3 Pa (50 mm Hg).
- the last stage of process according to the invention consists in separating, recover and dry the anhydrous dextrose crystals thus obtained.
- the crystalline mass containing at least 30% of individualized crystals is then separated from the liquor mother by all known methods in themselves, by example by spinning or filtering the ⁇ dextrose syrup anhydrous crystallized.
- the crystals are then purified by clearing with water, then dried at a lower temperature at the melting point of anhydrous dextrose ⁇ , preferably at a temperature of around 60 ° C, by any method also known, for example in an oven, or on a fluidized bed.
