Definitions
- the present invention is directed to a method for producing high purity D-psicose crystals using supersaturation from D-psicose solution.
- D-Phycose is not metabolized in the human body and has almost no calories, and has been reported as a sweetener that has little effect on weight gain by inhibiting body fat formation (Matuo, T. et. Al .. Asia Pac . J. Clin . Untr ., 10, 233-237, 2001; Matsuo, T. and K. Izumori, Asia Pac. J. Clin. Nutr., 13, S127, 2004).
- reaction solution containing D-psicose produced by the enzymatic reaction is a low-purity product containing about 20 to 30% (w / w) of D-psicose solids, a high purity of 98% (w / w) or more It is required to produce crystallization through high-purity separation using chromatography to prepare D-psicose crystal grains, but to date, more than 98% (w / w) of high-purity crystallization products have been industrialized for D-psicose. There is no.
- the industrialization technology for mass production has its limitations due to high manufacturing cost.
- the use of a large amount of ethanol in the manufacturing method of D-psicose crystallization has a low preference in the market due to the remaining ethanol odor in the final product, this also has a limitation of the technology in material aptitude.
- a concentrated crystallization method is used for crystallization of saccharides such as sucrose with a high growth rate of crystals
- a cooling crystallization method is generally used for crystallization of saccharides which have a significantly lower growth rate than sucrose.
- the crystallization method of sugars is usually made in a metastable zone, which means that the concentration of the solution ranges from the equilibrium concentration, that is, from the saturation concentration to the lowest super saturation.
- the crystallization phenomenon such as crystal nucleation does not occur at the concentration of this region, but when new crystals are introduced from the outside, crystal growth occurs and crystal size increases.
- the seed when seed is added to a solution having a saturation concentration or more to generate a crystal, the seed grows in a metastable zone and crystal growth occurs.
- the solution for crystallization is excessively concentrated or rapidly cooled, it becomes a supersaturation state exceeding the metastable zone, and new crystal nucleation is generated instead of crystal growth, which is an inhibitor of crystal growth due to the increase of population. Temperature conditions and initial entry supersaturation concentration are important for crystal growth.
- D-Phycose shows little change in crystal formation rate and crystal growth rate even in the supersaturation concentration range.
- the grain size is known as an important factor in the sugar crystallization industry.
- the separation of the crystals and the mother liquor in the crystal centrifuge system is easy due to the viscosity between the supersaturated agricultural tools. Because it is not made, the purity of the final product decreases due to the influence of the remaining mother liquor, and the remaining mother liquor causes the agglomeration of crystals with each other when drying, resulting in less product packaging or less product quality. Therefore, such particulate crystals are not suitable for mass production.
- an object of the present invention is to provide a method for obtaining a high-purity D-psicose separation solution that can be reused without removing unreacted fructose by using a continuous chromatographic separation without yeast fermentation.
- the obtained high-purity D-Phycose separation liquid is grown without the use of organic solvents such as ethanol to increase the crystal grain size to facilitate the separation of crystals and mother liquor, D-Piscose which can minimize the loss of separation, drying and packaging To provide a method of manufacturing.
- the present invention provides a D-psicose crystallization method that reduces the manufacturing cost by reducing the variable cost and fixed cost, and 98% (w / w) having a grain size of MA200 or more with improved flow of crystallization manufacturing process and productability as a product It is an object of the present invention to provide a method for producing a high-purity D-psicose.
- removing the impurities from the D- psychose solution to obtain a purified D- psychose solution Concentrating the purified D-psicose solution; Heat exchanging the concentrated D-psicose solution to 30 to 40 ° C .; Seeding the D-psicose solution at 30 to 40 ° C. to obtain a mask; It provides a method for producing a high-purity D-Phycose crystals having a purity of 98% (w / w) or more, particle size MA 200 or more, including the step of main crystallization using the seed crystallized mask.
- FIG. 1 is a graph showing the change in purity of thermal denaturation with temperature in 80 Brix (%) solution of D-psicose.
- 2 is a graph showing the grain size of D-psicose prepared by seed crystals.
- Figure 3 is a graph showing the grain size of the D-psicose prepared by the present crystal.
- One embodiment of the present invention removing the impurities from the D- psychose solution to obtain a purified D- psychose solution; Concentrating the purified D-psicose solution; Cooling the concentrated D-psicose solution through a heat exchanger to 30 to 40 ° C., preferably 35 to 40 ° C .; Seeding the D-psicose solution at 30 to 40 ° C. to obtain a mask; It relates to a method for producing a high-purity D- psychose crystals having a purity of 98% (w / w) or more, particle size MA 200 or more, comprising the step of using the seed crystallized mask to the main crystallization.
- the D-psicose solution used in the present invention may be prepared by a strain of the genus Corynebacterium expressing the D-psicose epimerase from fructose or a sicose epimerase isolated therefrom.
- 'Cycos epimerase' refers to a psychos-3-epimerase that has the activity of converting fructose into a psychose.
- the D-psicose solution is a cell obtained by culturing Corynebacterium glutamicum KCTC 13032, which produces D-psicose epimerase, as described in Korean Patent Application No. 2009-0118465.
- the enzyme isolated from the cells can be obtained by immobilization on an immobilization carrier such as sodium alginate, and then fed fructose to the substrate.
- the method of preparing the D-psicose crystal according to the present invention may include removing impurities from the D-psicose solution to obtain a purified D-psicose solution.
- the step of obtaining the purified D- psychose solution is to decolorize the D- psychose solution by passing through a column filled with a decolorant; Desalting the decolorized D-psicose solution by ion exchange resin chromatography; And passing the desalted D-psicose solution through a continuous chromatography filled with ion exchange resin attached to a calcium activator to obtain a purified D-psicose solution.
- the desalting of the D-psicose solution may be performed by chromatography passing through a column filled with a cation exchange resin and a column filled with an anion exchange resin.
- a strong basic anion resin in the ion exchange resin refining method for the preparation of D-psicose refining liquid the deterioration of purity occurs due to denaturation of D-psicose, and thus 100% weakly alkaline anionic resin is used to prepare high-purity D-psicose crystals. Should be used.
- the denaturation of D-psicose is also observed in mixed resins of strong acid cationic resins and strong alkaline anionic resins used in conventional saccharide tablets. Therefore, in the step of desalting the D-psicose solution, only 100% weakly alkaline anionic resin can be used for effective desalting purification without denaturation of D-psicose.
- separation by continuous chromatography may be performed to purify high purity D-psicose.
- the content of D-psicose in the D-psicose solution for obtaining D-psicose crystals should be 90 to 95% or more, more preferably 95% or more.
- Direct crystallization cannot be performed because the purity of D-psicose in the D-psicose solution prepared by D-psicose epimerase is as low as 24% (w / w).
- impurities are removed by decolorization and desalting prior to the crystallization step, followed by continuous chromatography, i.e., chromatography on a column packed with ion exchange resins with calcium activators. Psycho can be separated and purified.
- the method for preparing D-psicose crystals according to the present invention unlike the method of gradually cooling from a high temperature to a constant temperature section per unit time within the supersaturation concentration range, which is a conventional saccharide crystallization method, of 80 to 85 Brix (%)
- the D-psicose solution concentrated in the supersaturated concentration range (D-psicose solution ⁇ 100 / total solution) was rapidly cooled to a temperature of 30-40 ° C. at a temperature of 5-20 ° C. per hour through a heat exchanger, followed by a crystallization device input solution. use.
- the crystallization time of the D- psychos should be made of 80 to 120 hours or more, the concentration of the concentrated D- psychos solution is rapidly increased by 30 to 40 °C by 5 to 20 °C per hour through a heat exchanger within the supersaturated concentration range After cooling, the crystallization of D-Phycose is carried out by adding to a crystallization apparatus and repeating the temperature increase and cooling of 5 to 10 times within the crystallization temperature section within the range of 30 to 40 ° C. That is, a 30 to 40 ° C.
- the D-psicose solution concentrated in a supersaturation concentration range of 80 to 85 Brix (%) at 5 to 20% (v / v) of the crystallizer operation amount is added thereto, and then the cooling water of the crystallizer is added.
- the temperature is circulated in the range of 30 to 35 ° C., and the prepared D-psicose seed (Seed) is added at 10 to 100 ppm (v / v) based on the initial dose to start the D-psicose crystallization reaction.
- the mask means a slurry state in which a crystal and a solution are mixed when the D-psicose seed starts a crystallization reaction.
- the D-psicose solution of 30 to 40 ° C. concentrated was added thereto, and this operation was repeated 5 to 10 times, and the internal temperature of the crystal mask was repeatedly heated and cooled 5 to 10 times within the range of 30 to 40 ° C.

- the D-psicose crystals obtained by the production method of the present invention may be specifically grain size MA 200 or more, more specifically grain size MA 300 or more.
- Grain size is a measure of the average size of a crystal.
- JIS or ASTM the number of crystals included in a 25 mm square area of a 100-micron magnified photomicrograph is measured, and the number is referred to as a grain size number and represents a particle size. Recently, it is also used to mean the average size of crystals. In the present invention, it is used in the sense of the average size of the crystal.
- the method for measuring the grain size of D-psicose is not limited and may be a method commonly used in the art.
- Non-limiting examples of measuring grain size include comparative method (FGC), cleavage method (FGI), flat method (FGP).
- D-psicose crystals having a grain size of MA 200 or more seed crystallization and main crystallization must be carried out in two stages under the above conditions, and seed crystallization is performed at 5 to 20% (v / v) of the main crystallization operation amount. It is preferable.
- the particle size of the seed crystallization prepared in the present invention is obtained in the range of MA 100 to MA 150, and the entire amount of seed crystallization is transferred to the main crystallization apparatus to carry out the main crystallization in the same manner as the above operation.
- more than 98% (w / w) high purity D-psicose having a grain size of MA 300 or more can be prepared.
- a conventionally used sugar crystallization apparatus may be used as it is or as appropriately modified, and the separation device of the high purity D-psicose crystal and the mother liquor from the final crystal mask may also be used as is. Or it can transform suitably and can utilize.
- D-psicose As disclosed in Korean Patent Application No. 10-2009-0118465, fermentation culture of Corynebacterium glutamicum KCTC 13032 and the D-fructose of a fructose by a carrier immobilized with the microorganism or the D-cycos epimerase isolated therefrom D-psicose was prepared by a process for continuous production of D-psicose, including the conversion to psychos. The purity of the D-psicose prepared by this method was low at about 24% (w / w) to crystallize directly. The resulting D-psicose solution was concentrated to 50 Brix (%), and then passed through a decolorization column filled with granulated active carbon to remove colored material in the concentrate.
- the purity of the reaction resultant obtained in the preparation example is 24% (w / w), and for crystallization, the purity of the crystallized D-psicose should be increased to 90 to 95% (w / w) or more.
- the ions in the D-psicose solution must be removed.
- the ionic component is present in the separation target solution, the ionic component and the active group of the separation resin are replaced to degrade the separation ability, so that it is impossible to continuously separate D-psicose with a purity of 90 to 95% (w / w).
- a strong acid cation exchange resin (Bayer S1668) substituted with a hydrogen group and a weakly basic anion exchange resin (Bayer Bayer S4528) substituted with a hydroxyl group were obtained.
- the packed column was passed through to remove ionic components in the solution. Confirmation of the ion component removal was measured by an electroconductor and adjusted to be 10 microsiemens per cm or less, and the purity of the D-psicose was maintained at 24% (w / w).
- weakly basic anion exchange resins since some of them have strong basic characteristics, 100% weakly basic anionic resins having no strong basic characteristics should be used to proceed with desalting without loss due to the purity decrease of D-psicose. .
- the purity of the final D-psychose crystal obtained after separation, drying, and sieving of the D-psychose seed crystallization mask using a high-purity D-psychose crystal and a crystal centrifugal separator through mother liquor separation was 99.4% (w / w), the particle size was MA 135.5, the yield was 35.2%.
- D-psicose main crystallization is carried out with the D-psicose seed crystallization mask prepared in Example 3 above. After 20% (v / v) of the crystallizer operation amount, the D-psicose seed crystallization mask was introduced, and the cooling water temperature of the crystallization unit was circulated to 35 ° C. w / w) Concentrate the D-psicose solution to 80.0 Brix (%), rapidly cool it to 40 ° C by 10 ° C per hour through a heat exchanger, and simultaneously add 20% (v / v) of the crystallizer operation. The total amount of crystallization starts at 40% (v / v) of the crystallizer operation.
- a 24% (w / w) solution of the decolorized D-psicose purity obtained in the above preparation was filled with a strongly acidic cation exchange resin (Bayer S1668) substituted with a hydrogen group and a weakly basic anion exchange resin (Bayer S4268) substituted with a hydroxyl group.
- a strongly acidic cation exchange resin (Bayer S1668) substituted with a hydrogen group
- a weakly basic anion exchange resin (Bayer S4268) substituted with a hydroxyl group.
- an ion exchange column (Bayer NM60) mixed with a strong acidic cation exchange resin and a strong base anion exchange resin was passed in a final step to remove ionic components in the solution. Confirmation of ionic component removal was measured by an electroconductor, and adjusted to be less than 10 microsiemens per cm, and the purity of D-psicose was reduced to 21.2% (w / w).
- a strong acid cation exchange resin (Bayer S1668) substituted with a hydrogen group and a weakly basic anion exchange resin (Bayer S4268) substituted with a hydroxyl group in a 24% (w / w) solution of the reaction resultant obtained in the above Preparation Example The packed column was passed through to remove ionic components in the solution. Confirmation of the ion component removal was measured by an electroconductor, and adjusted to be less than 10 microsiemens per unit cm, and the purity of the D-psicose was reduced to 22.8% (w / w).
