Description

  The present invention relates to a β-maltose hydrous crystal-containing powder and a method for producing the same, and more specifically, and more specifically, β-maltose hydrous crystal-containing powder that is powdered by a spray method, has excellent solubility in an aqueous medium, and is easy to handle. Further, the present invention relates to a method for producing the same and a use thereof for various compositions such as foods, drinks, cosmetics and pharmaceuticals in which the powder is dissolved and contained in an aqueous medium.

  Conventionally, a large amount of sugar has been consumed as a sweetener. However, since sugar is too sweet, it does not meet recent tastes, and has the disadvantage that it is the main inducer of caries.

  In recent years, it has been proposed to use various sugars in order to eliminate the disadvantages of sugar. Especially, maltose produced from starch has lower sweetness compared to sugar, less concern about induction of tooth decay, and flavor. Currently, food-grade β-maltose hydrous crystal-containing powders are commercially available from Hayashibara Corporation as registered trademarks “San Mart” and “San Mart S”. Further expansion of consumption can be expected.

  The β-maltose hydrous crystal-containing powder is usually produced by a honey method, a cutting method, or a spray method using a maltose-containing solution as a raw material.

  Among these, the honey-concentration method concentrated the raw material maltose-containing solution and gradually cooled it with stirring under the condition that β-maltose hydrous crystals coexisted as seed crystals to crystallize β-maltose hydrous crystals. This is a method for producing a powder in which a mass kit is obtained, which is separated into crystals and nectar by centrifugation or the like, and the crystal portion is collected and dried. This method has a disadvantage that the yield of β-maltose hydrous crystal powder is low due to the fact that nectar is by-produced, although extremely high purity crystal powder can be obtained.

  On the other hand, in the cutting method and the spraying method, normally, the raw material maltose-containing solution is concentrated and made into a mass kit. Then, in the cutting method, the whole amount is solidified and aged, then cut and dried to collect the powder. Alternatively, the spray method is a powder production method in which a mass kit spray-dried is aged and collected. Although these methods cannot increase the purity of maltose, they can be pulverized in total, and do not produce nectar as a byproduct, which is industrially advantageous.

  Specifically, for the cutting method, normally, a maltose-containing solution is concentrated, β-maltose hydrated crystals are added as seed crystals, and β-maltose hydrated crystals are partially crystallized to form a mass kit, and then the entire amount is blocked. This product is solidified and aged, and is then cut, dried and sieved to produce a stable β-maltose hydrous crystal-containing powder. The product produced industrially by this cutting method is Hayashibara Corporation. It is sold as a registered trademark "San Mart" by Shoji. According to this cutting method, the entire amount of raw material maltose can be pulverized, which is industrially advantageous. However, this cutting method requires 5 to 15 days to solidify and age the mass kit in blocks. Not only does it require a period of time, it also has the disadvantage of requiring complicated processes for subsequent cutting, drying and sieving.

  On the other hand, for the spraying method, conventionally, a maltose-containing solution is concentrated, β-maltose hydrated crystals are added as seed crystals to partially crystallize β-maltose hydrated crystals to form a mass kit, which is then spray-dried. There has been known a method of producing a powder containing β-maltose hydrous crystals by pulverization and aging (Patent Document 1, Patent Document 2). This spray method is industrially most advantageous because it does not require a long period for solidifying and aging the mass kit, but it still takes 3 to 4 days for its production, and it is smoothly and continuously produced by the spray method. It was difficult to produce a powder.

  Thereafter, in order to improve this, the content of carbohydrates other than maltose, specifically, glucose, maltotriose and oligosaccharides having a glucose polymerization degree of 4 or more are reduced as much as possible to reduce maltose in terms of anhydride. By using an extremely high-purity maltose-containing solution having a content of about 95% by mass (hereinafter, unless otherwise specified, mass% is simply abbreviated as%), β- A method for producing maltose hydrous crystal-containing powder in a relatively short time was established, and it was sold by Hayashibara Shoji Co., Ltd. under the registered trademark “Sanmalto S”. However, according to the knowledge found by the present inventors for the first time, the β-maltose hydrous crystal-containing powder obtained by this spraying method is surprisingly not necessarily satisfactory in solubility in an aqueous medium. It has been found that there is a need to further improve the performance.

Japanese Patent Publication No.54-3937 Japanese Patent Publication No.54-27325

  The present invention has been made in order to solve the disadvantages of the above-mentioned spraying method newly found by the present inventors, and employs a spraying method that is industrially advantageous and can be carried out at low cost, and is dissolved in an aqueous medium. It is an object of the present invention to provide a β-maltose hydrous crystal-containing powder that is excellent in properties and easy to handle, a method for producing the same, and an application.

  In order to solve the above problems, the present inventors have studied various physical properties of β-maltose hydrous crystal-containing powders that are pulverized by a spray method, and in particular, the sugar composition of the raw material maltose-containing solution and the resulting powder. Focusing on the relationship with various physical properties, we conducted extensive research. That is, a mass kit prepared from a maltose-containing solution of various sugar compositions is powdered by a spray method, first kept in a relatively high humidity and low temperature atmosphere, and then kept in a relatively high humidity and low temperature atmosphere. -Maltose hydrous crystal-containing powder was collected, and various properties such as hygroscopicity, adhesiveness, solubility, α-anomer content, crystallinity, etc. of this powder were examined in detail.

  As a result, (1) β-maltose hydrous powder which is powdered by a spray method, contains 86% to 93% maltose and 2% or more glucose in terms of anhydride, and has a crystallinity of 62% to less than 72%. The crystal-containing powder was found to be a powder having excellent solubility in an aqueous medium and easy to handle. As a method for producing the powder, (2) maltose 86% to less than 93% in terms of anhydride and A solution containing 2% or more of glucose is used as a mass kit in which β-maltose hydrous crystals are crystallized, then powdered by a spray method, and further maintained in a relatively low humidity and high temperature atmosphere to maintain α in maltose. A powder containing a high amount of anomer, and then kept in a relatively high humidity and low temperature atmosphere to reduce the α-anomer content in the maltose of the sprayed powder to 7% or more and less than 14%; A method for producing a β-maltose hydrous crystal-containing powder characterized by collecting a powder having a crystallinity of 62% or more and less than 72%. (3), (1) or ( The present invention was completed by establishing a composition in which β-maltose hydrous crystal-containing powder obtained by the production method 2) was dissolved and contained in an aqueous medium.

  According to the present invention, a β-maltose hydrous crystal-containing powder excellent in solubility in an aqueous medium can be easily produced at low cost.

  The maltose-containing solution used as a raw material for the β-maltose hydrous crystal-containing powder of the present invention is pulverized by a spray method and contains 86% to less than 93% maltose and 2% or more glucose in terms of anhydride. Any β-maltose hydrous crystal-containing powder having a degree of 62% or more and less than 72% can be used. Examples of methods for producing such a maltose-containing solution include Japanese Patent Publication No. 54-3937 and Japanese Patent Publication No. 56. As disclosed in Japanese Patent No. 28153, Japanese Patent Publication No. 57-3356, Japanese Patent No. 2518646, and the like, various starches are heated and gelatinized and then α-amylase (EC 3.2.1.1.1). ) Or by acid or mechanical force to liquefy to the lowest possible hydrolysis rate, and then β-amylase (EC 3.2.1.2) and starch debranching enzyme By the action of one) of the pullulanase EC.3.2.1.41 or isoamylase EC.3.2.1.68 there is a method for producing and saccharified.

  The solution containing maltose 86% or more and less than 93% and glucose 2% or more, as referred to in the present invention, is produced from starch as described above, and usually maltotriose and glucose polymerization as other carbohydrates. Contains oligosaccharides with a degree of 4 or more. Since this maltotriose and oligosaccharide having a glucose polymerization degree of 4 or more are liable to inhibit crystallization of β-maltose hydrous crystals from a maltose-containing solution, it is desirable to reduce this content as much as possible. Especially, for maltotriose, The content is preferably less than 2% in terms of anhydride.

  As a method for reducing the content of maltotriose and oligosaccharide having a glucose polymerization degree of 4 or more, for example, as disclosed in Japanese Patent Publication No. 56-28154, Japanese Patent No. 2696530, etc., maltotriose or glucose Reducing the content of maltotriose or oligosaccharides having a polymerization degree of glucose of 4 or more by acting on enzymes having a polymerization degree of 4 or more and acting on enzymes that decompose them to produce glucose or maltose. At the same time, the maltose content can be increased. In addition, it is also possible to separate and remove maltotriose or oligosaccharide having a glucose polymerization degree of 4 or more using a UF membrane, reverse osmosis membrane, activated carbon, or the like, as described in JP-B-62-51120 and JP-B-5-79316. As disclosed in publications and the like, maltotriose or higher oligosaccharides can also be separated and removed using a chromatographic separation method using an ion exchange resin.

  One of the features of the present invention is that a maltose content is 86% or more and less than 93% in terms of anhydride by adopting a series of production methods combining the following steps and increasing the crystallization rate of maltose. In this case, it is dissolved in a spray method despite the fact that carbohydrates other than maltose, such as glucose, maltotriose and oligosaccharides with a glucose polymerization degree of 4 or higher, are present in a relatively large amount of 7% to less than 14%. A β-maltose hydrous crystal-containing powder that is excellent in properties and easy to handle can be easily produced in a relatively short time.

  That is, a series of production methods are (a) using a maltose-containing solution of the sugar composition used in the present invention as a mass kit, and then (b) spraying, preferably by a spray drying method using a high-pressure nozzle or a rotating disk. In order to increase the crystallization rate of maltose contained in the powder, preferably (c), which has a relatively low humidity, the powder is preferably less than 10% moisture, more preferably about 5-9%. At a high temperature atmosphere, preferably less than 40% relative humidity (RH), more preferably less than 20%, preferably above 75 ° C., more preferably 80-110 ° C. for about 1 to 4 hours. , A powder containing a high content of α-anomer which is a maltose isomer, preferably a powder having a content of α-anomer in maltose of 35% or more, and (d) a relatively high humidity and low temperature atmosphere, desired Alternatively, the relative humidity (RH) exceeds 70%, more preferably 80% or more, preferably less than 50 ° C., more preferably 20 to 45 ° C. for about 5 to 10 hours. The α-anomer content is reduced to 7% or more and less than 14%, and (e) is achieved by collecting β-maltose hydrous crystal-containing powder having a crystallinity of 62% or more and less than 72%.

  Hereafter, each said process is demonstrated in detail. In the step (a), the maltose-containing solution is concentrated, desirably a concentrated solution having a water content of 15 to 30%, and an appropriate amount of β-maltose hydrous crystal as a seed crystal, usually about 0.1 to 5%. A mass kit is produced while gradually cooling and stirring together. At this time, the crystallization rate of β-maltose hydrous crystals (hereinafter, unless otherwise specified, the crystallization rate means that the mass kit is divided into crystals and nectar, and (crystal anhydride weight / mass kit). The weight of the anhydride)) x 100.) The higher the value of), the higher the viscosity of the mass kit.

  In the step (b), the present inventors reduced the viscosity by heating and raising the temperature of the high-viscosity mass kit containing β-maltose hydrous crystals within a range that does not substantially reduce the crystallization rate. As a result, it was found that a β-maltose hydrous crystal-containing powder can be easily produced by a spray method. That is, the inventors of the present invention, when the mass kit is heated and heated, the viscosity immediately decreases as the temperature increases, but the generated crystals do not dissolve in a short time even if the temperature rises somewhat, and the crystallization rate The viscosity of the mass kit is desirably increased by raising the temperature of the mass kit without substantially reducing the crystallization rate, and desirably the viscosity of the mass kit is 50,000 cp (hereinafter referred to as “special” in the present specification). Unless otherwise indicated, the viscosity cp means a value measured by rotating at 4 rpm using a No. 7 rotor using a BH rotational viscometer. It has become clear that the drying efficiency can be improved.

  The method for raising the temperature is not particularly limited. For example, known methods such as flowing warm water through a jacket of a crystallizer containing a mass kit, adding steam directly into the crystallizer, and heating using a heat exchanger between the crystallizer and the liquid feed pump are appropriately used. Can be adopted. The degree of temperature rise is such that the viscosity of the mass kit can be sprayed, specifically, 50,000 cp or less, preferably 40,000 cp or less, usually 2 to 15 ° C., preferably 2 to 10 ° C. It is preferable to carry out in as short a time as possible without causing a decrease in the crystallization rate.

  In the step (c), it is also possible to advantageously employ a method in which the powder is brought into contact with a small amount of anhydrous α-maltose crystals to promote isomerization to α-anomer in maltose. As maltose isomers, there are α-anomer and β-anomer. Known crystal forms include anhydrous α-maltose crystals, hydrous β-maltose crystals, anhydrous β-maltose crystals, and α and β complex crystals in which α-maltose and β-maltose coexist at a certain ratio.

  The content of α-anomer in maltose of 7% or more and less than 14% means the content of α-anomer in maltose, regardless of whether the form is amorphous or crystalline. In general, when the content of α-anomer in maltose is 14% or more, it means that there is a lot of amorphous maltose or α-maltose anhydrous crystals, and conversely, maltose. When the content of α-anomer is less than 7%, the rest is β-maltose, which means that the content of water containing β-maltose or anhydrous crystals is high.

  Further, in the step (d), after the α-anomer content in the maltose is reduced to 7% or more and less than 14% by keeping it for about 5 to 10 hours, it is advantageous to add a drying step if necessary. Can be implemented.

  In the step (e), the obtained β-maltose hydrous crystal-containing powder is subjected to a particle size distribution test (starch sugar related industrial analysis method, published in 1991, released by Food Chemical Newspaper Co., Ltd. on page 118). According to the measurement method, a sample of 50 g was measured for 15 minutes using a JIS / Z8801 sieve) and contained a large amount of powder having a relatively large particle size, and usually more than 60% of the powder exceeding 106 μm In many cases, it contains 40% or more of powders exceeding 150 μm and not more than 300 μm. In addition, the powder of more than 150 μm and less than 300 μm often contains agglomerates produced by adhering and agglomerating a plurality of particles in the course of dropping in the spray dryer or in the process from aging to completion of drying.

  The β-maltose hydrous crystal-containing powder of the present invention thus obtained is a powder that is excellent in solubility in an aqueous medium, has good storage stability and fluidity, and is easy to handle.

  The aqueous medium referred to in the present invention means a liquid, paste, semi-solid or solid containing a large amount of water or water that can dissolve and contain the β-maltose hydrous crystal-containing powder. In particular, the aqueous medium having viscosity includes, for example, sugars, starches, fats, proteins, polyphenols, emulsifiers, and the like.

In addition, it has good quality and elegant sweetness and has an action of inhibiting the production of dextran, which is one of the causes of dental caries, and is also suitably used as a sweetener that hardly causes caries.

<Experiment: Effect of raw sugar composition on physical properties of various β-maltose crystal-containing powders>
The influence of the raw material sugar composition on the physical properties of various β-maltose crystal-containing powders by the spray method was investigated. As the test powder, various raw material maltose-containing solutions having different sugar compositions were prepared and used as a powder containing β-maltose hydrous crystals by a spray method. Maltose-containing solutions are commercially available purified maltose (registered trademark “Sanmalto S”, sold by Hayashibara Shoji Co., Ltd.), or glucose (reagent grade sold by Wako Pure Chemical Industries, Ltd.), maltotriose, maltotetraose. And / or maltopentaose (all are reagents manufactured by Hayashibara Biochemical Laboratories Co., Ltd.) to prepare maltose-containing solutions of various compositions.

  Preparation of the β-maltose hydrous crystal-containing powder by a spraying method was performed as follows. That is, after concentrating the raw material maltose-containing solution to a water content of 25%, it was transferred to an auxiliary crystal machine, and 1% of β-maltose water-containing crystal was added as a seed crystal, and the temperature was gradually lowered to 30 ° C. while slowly stirring. Β-maltose hydrous crystals were partially crystallized over a period of 18 hours to obtain a mass kit. The crystallization rate of the mass kit was 36 to 43%. After the auxiliary crystal is finished, if the viscosity of the mass kit exceeds 50,000 cp, heat it before sending it with a high-pressure pump, and increase the viscosity to about 45,000 cp without substantially reducing the crystallization rate. While lowering, spraying was performed using a pressure nozzle. The temperature of the hot air for drying at the time of spraying is 75 ° C, the hot air blowing method is a vertical downward flow in the spray dryer, and the amount of blown air is such that the moisture of the dry powder when taken out from the spray dryer is about 8.5% Adjusted.

  The obtained powder was immediately mixed and contacted with 0.2% anhydrous α-maltose crystals as seed crystals, stored for 2 hours in a constant temperature and humidity machine at a temperature of 90 ° C. and a relative humidity (RH) of 20%, and then 30 It was kept for 5 hours in a constant temperature and humidity machine at 80 ° C. and a relative humidity (RH) and aged to obtain a β-maltose hydrous crystal-containing powder. This powder was subjected to various physical property tests described below.

  In the physical property test, purified maltose (registered trademark “Sanmalto S”, traded by Hayashibara Corporation), hydrated reagent β-maltose crystal (manufactured by Hayashibara Biochemical Laboratories, Inc., trade name “Maltose HHH”) and α were used as controls. -Anhydrous maltose crystal (registered trademark "Fine Tose" sold by Hayashibara Shoji Co., Ltd.) was used.

The physical property test was conducted by the following method.
A. In the sugar composition analysis, liquid chromatography using a KS-801 column (manufactured by Showa Denko) or a CH04SS column (manufactured by MCI) was performed, and the sugar composition was determined from the area ratio of the chromatogram.

  B. In the hygroscopicity test, the sample placed in the aluminum cup is not covered, placed in a desiccator adjusted to 75.2% RH (equilibrated with a saturated sodium chloride aqueous solution), and left at 25 ° C. for 3 days. Measurement was made to determine the rate of weight increase (%) with respect to the original sample, and it was defined as hygroscopicity.

  C. The sticking property was determined to be sticky if the sample in the aluminum cup taken out after being left for 3 days in the hygroscopic test was visually observed and solidified as a result of the sample absorbing moisture compared to before the test.

  D. The solubility test is as follows: (i) As a solubility test in water, 5 ml of deionized water at 25 ° C. is put in a plastic test tube, and 1 g of maltose crystal-containing powder having various sugar compositions is added to the solution at a time. The tube was sealed in a state of being submerged in water, held in a thermostatic bath at 50 ° C., and the dissolved state of the powder was visually observed every 20 minutes. In the evaluation, the time (minutes) required until the powder was completely dissolved and became transparent was determined. As a criterion for evaluation, it was judged that the shorter the time until the powder disappears, the better the solubility.

  (Ii) As a solubility test for a dextrin-containing solution, 5 ml of a dextrin having a viscosity of 17% (manufactured by Matsutani Chemical Industry Co., Ltd., “Paindex # 1”) in an aqueous solution is placed in a plastic test tube. Add 1 g of maltose crystal-containing powder with various sugar compositions in the same manner as in the water solubility test of (i) above, seal the powder completely in water, and hold it in a thermostat at 50 ° C. Then, the state of the powder was visually observed. The standard of evaluation was the same as in the case of the solubility test in water of (i) above.

  E. For analysis of maltose isomers, the sample was dissolved in anhydrous pyridine, TMS-treated, gas chromatography using 2% OV-17 chromosolve W (AW-DMCS) was performed, and α was determined from the area ratio of the chromatogram. , Β-anomeric ratio was determined.

  F. The measurement of the crystallinity of the powder was carried out using the X-ray diffractometer Geiger Flex RDA-IIB (using Cu and Kα rays) (manufactured by Rigaku Denki Co., Ltd.). (Acta Crystallographica: Acta Crystallographica, Vol. 14, page 1180, 1961). Among the measured powders, typical powder X-ray diffraction patterns are shown in FIGS.

  The sugar composition of the raw material maltose-containing solution and the test results on the hygroscopicity, stickiness, solubility, α-anomer content, and crystallinity of each powder obtained are summarized in Table 1 as the physical properties of various maltose crystal-containing powders. It was.

  As is apparent from Table 1, test no.

No storage was observed, it was found that the storage stability was good, the handling was easy, and the solubility in an aqueous medium such as a dextrin-containing solution having water and viscosity was excellent. In contrast, test no. 1 and 2 having a maltose content as low as 82.4% and 84.2%, and β obtained by a spray system in which the α-anomer content in maltose as maltose isomer exceeds 14% and the crystallinity is less than 62%. -The maltose hydrous crystal-containing powder was an unstable powder that was excellent in solubility in an aqueous medium but had high hygroscopicity, high stickiness, and poor storage stability.

  On the other hand, test no.
