Description

TECHNICAL FIELD The present invention relates to a dehydrating agent and a method for dehydrating a water-containing substance using the same.

More specifically, the present invention relates to a dehydrating agent comprising crystalline α-maltose and a method for dehydrating a hydrous substance, which comprises adding crystalline α-maltose to a hydrous substance and converting the hydrous substance into β-maltose hydrous crystals.

(Prior Art) In general, dried foods such as seasoned seaweed, oysters, rice cakes, and cookies are enclosed in cans, bottles, moisture-proof containers such as aluminum-polyethylene laminated containers, and further, silica gel, Water is removed from the atmosphere using a dehydrating agent such as calcium oxide, and the relative humidity is reduced to maintain quality.

However, there is a risk of accidentally putting these dehydrating agents into the mouth, contacting the skin and mucous membranes, and the development of safer dehydrating agents is desired.

On the other hand, the water content in food has a great influence not only on the physical properties of food but also on the shelf life thereof. In general, water-containing foods are susceptible to microbial contamination and further susceptible to deterioration such as hydrolysis, rancidity and browning.

Usually, in order to extend the storage period of water-containing foods, as a method of reducing the water content in the food, for example, sugar pickled as found in buntan pickles, salt pickled as found in takuan pickles,
Various dehydration methods such as drying as found in powdered miso and powdered fruit juice have been adopted.

However, sugar is too sweet to meet recent tastes, is a main inducer of caries, and has a drawback that it causes an increase in blood cholesterol when taken in large amounts. It has also been pointed out that excessive intake of salt is a major cause of adult diseases such as hypertension and cancer, and instructions have been given to reduce its intake as much as possible.

Further, in the drying method, it is inevitable that aroma is volatilized in the process, and only foods with poor flavor can be obtained.

Further, pharmaceuticals, for example, lymphokines, hormones, vitamins, probiotic agents, enzymes, pharmaceuticals containing physiologically active substances such as antibiotics are unstable in the presence of high water content,
In order to improve its stability, it is commercialized by a drying method such as heat drying and vacuum drying in the presence of a large amount of stabilizer.

What is used as this stabilizer is albumin,
There are water-soluble polymer compounds such as casein, gelatin and hydroxyethyl starch.

However, it is extremely difficult to dry in the presence of a stabilizer such as a water-soluble polymer compound, and not only a great amount of energy is wasted, but also the obtained dried product becomes sparingly water-soluble or the activity of the physiologically active substance is reduced. There is a risk of causing it.

(Problems to be Solved by the Invention) The present inventors have focused on maltose for the purpose of eliminating the drawbacks of conventional dehydration methods such as drying methods.
We have conducted extensive research on its use as a dehydrating agent.

As a result, it was found that crystalline α-maltose acts as a strong dehydrating agent by including it in hydrous foods such as hydrous foods and hydrous pharmaceuticals, and converting it to β-maltose hydrous crystals, and the flavor was found. The present invention has been completed by confirming that good and high-quality dehydrated foods and highly active and stable dehydrated medicines can be easily produced.

The present invention focuses on crystalline α-maltose, which has never been noticed as a dehydrating agent in the past.
-The present invention provides a method for dehydrating a water-containing substance by incorporating maltose as a dehydrating agent.

The dehydration method of the water-containing material in the present invention is preferable as a dehydration method of containing water, in particular, containing free water different from bound water such as crystal water. When reducing the water content contained in the enclosed moisture-proof container, further, for example,
It can be advantageously applied to the case of reducing the water content of various hydrates such as foods, pharmaceuticals, cosmetics, industrial chemicals, raw materials or processing intermediates thereof.

When crystalline α-maltose is added to these hydrous substances, the crystalline α-maltose strongly takes up about 5% of its weight of water as water of crystallization of β-maltose hydrous crystals from the hydrous substance. It was found to substantially reduce water content and dehydrate.

For example, in a moisture-proof container containing dried food such as seasoned seaweed and cookies, a crystalline α filled in a moisture-permeable sachet made of paper or the like.
-By allowing maltose to coexist, or by compounding crystalline α-maltose in a powdered material such as a premix powder, a granular seasoning, a powder intestinal preparation, and a granular digestive agent, and packaging and enclosing the same, Extremely reduces relative humidity,
It has been found that dried foods, powdered products, etc. can be maintained with high quality and stability for a long period of time.

At this time, the crystalline α-maltose traps water to form β-maltose.
There is no stickiness or flow even after conversion to maltose hydrous crystals, there is no risk of contaminating dry foods or moisture-proof containers, and powdery substances adhere or congeal. Can be prevented.

Furthermore, maltose itself is a non-toxic, non-harmful natural sweetener with no danger.

Also, for example, brandy, vinegar, royal jelly,
In the case of liquid foods such as fresh cream and mayonnaise, and high-moisture food products such as paste, by adding crystalline α-maltose and converting it into β-maltose hydrous crystals, the water content is substantially reduced. Quality dehydrated foods, for example, foods in the form of muskets, powders, etc., can be produced very easily. Since this method does not require harsh conditions such as heating and drying, it does not deteriorate the liquid or pasty high-moisture food product by deterioration, and can be easily converted into a dehydrated food product with good flavor and reduced water content. Have

At this time, crystalline α-maltose was added in an amount corresponding to the amount of water contained in the food raw material or the like, and the crystalline α-maltose was partially converted to β-maltose hydrous crystals, in other words, β- Obtaining dehydrated food containing crystalline α-maltose together with maltose hydrous crystals, and enclosing this in a moisture-proof container, water in the atmosphere in the container is crystallized water of β-maltose hydrous crystals due to crystalline α-maltose. It was found that the relative humidity can be extremely reduced and the inside of the container can be maintained in a highly dry state.

As a result, the dehydrated food obtained by the method of the present invention not only prevents microbial contamination, but also prevents deterioration such as hydrolysis, rancidity, and browning, and maintains a good flavor and high-quality product stably for a long period of time. It has been found.

Also, in the case of aqueous solutions of lymphokines, antibiotics, etc., medicinal ginseng extract, paste medicines such as soft-shelled turtle extract, by adding crystalline α-maltose to these β-
By converting to maltose hydrous crystal, a high-quality dehydrated drug with substantially reduced water content, for example, a drug in the form of a musket or a powder can be extremely easily manufactured.

This method does not require harsh conditions such as heat drying,
Further, since crystalline α-maltose acts not only as a dehydrating agent but also as a stabilizer, a high-quality and stable dehydrated drug can be produced.

Also, since it is not necessary to worry about wasting energy for drying the stabilizer such as water-soluble polymer compound,
By appropriately using it as necessary, it is also possible to advantageously carry out the production of a dehydrated drug of higher quality and stability.

Further, for example, a certain amount of crystalline α-maltose is placed in a vial, and an aqueous solution containing physiologically active substances such as lymphokines and hormones is added to the crystalline α-maltose.
-It is also advantageous to add a smaller amount of water than the amount of water required for converting maltose to a β-maltose hydrous substance, and then seal the product to produce a solid preparation for injection or the like.

In this case, it has been found that crystalline α-maltose can not only dehydrate the aqueous solution containing the physiologically active substance but also dehumidify and dry the atmosphere in the vial.

As a result, the dehydrated pharmaceutical product obtained by the present invention is characterized in that not only its manufacturing process is easy, but also its high quality can be stably maintained for a long period of time, and further, it is rapidly dissolved in water during use. It was also found to have.

As described above, the dehydrating agent using the crystalline α-maltose of the present invention is edible unlike the conventionally known dehydrating agents such as silica gel and calcium carbide, and can be metabolized to provide nutrition. It can be advantageously used not only as a sugar dehydrating agent but also as a stabilizer for various physiologically active substances.

Prior to the present invention, the present inventors have studied a method for producing crystalline α-maltose, particularly crystalline α-maltose powder.

First, as a result of detailed examination of the raw material maltose for producing the crystalline α-maltose powder, it was found that high-purity maltose having a solid content of 85 w / w% or more is suitable.

The high-purity maltose used as the raw material may be a commercially available β-maltose hydrous crystal, or may be prepared by saccharifying starch according to a conventional method.

As a method for preparing high-purity maltose from starch, for example, β-amylase is produced by allowing β-amylase to act on gelatinized or liquefied starch disclosed in JP-B-56-11437 and JP-B-56-17078. A method for separating high-purity maltose by separating maltose from polymer dextrin, or, for example, Japanese Patent Publication No. 47-13089 and Japanese Patent Publication No. 54-3938.
There is a method of collecting high-purity maltose by allowing starch debranching enzymes such as isoamylase and pullulanase and β-amylase to act on gelatinized or liquefied starch disclosed in Japanese Patent Laid-Open Publication No. 2003-242242.

Further, contaminating sugars such as maltotriose contained in the high-purity maltose obtained by these methods include, for example, Japanese Patent Publication
56-28153 publication, JP-B 57-3356 publication, JP-B 56-2
The maltose is produced by reacting the enzyme disclosed in Japanese Patent No. 8154 or the like, and further, for example, JP-A-58-23.
It is also convenient to further increase the maltose purity by a method such as removing contaminating sugars by a column fractionation method using a salt-type strongly acidic cation exchange resin disclosed in Japanese Patent Publication No. 799, etc. The fractionation method may be a fixed bed method, a moving bed method, or a pseudo moving bed method.

In order to produce crystalline α-maltose powder from high-purity maltose having a solid content of 85 w / w% or more thus obtained, for example, these high-purity maltose have a water content of about 10 w / w.
%, Preferably 2.0 w / w% or more and less than 9.5 w / w% of high-concentration syrup, and the syrup is mixed with seed crystals at 50 ° C. or higher.
It may be produced by crystallizing crystalline α-maltose while maintaining the temperature range of 130 ° C.

Crystalline α-maltose does not substantially crystallize at a water content of 10 w / w% or more, and particularly at a water content of 12 w / w% or more and less than 25 w / w%,
Rather, it was found that not only the crystalline α-maltose of the seed crystal is likely to dissolve and disappear, but also the β-maltose hydrous crystal is more likely to crystallize. It was also found that crystallization of crystalline α-maltose from a high-concentration syrup having a water content of less than 2.0 w / w% was relatively slow.

The temperature during crystallization is preferably in the range of 50 ° C to 130 ° C, particularly preferably 60 ° C to 120 ° C. 50
It was found that at a temperature of less than 0 ° C, crystallization of crystalline α-maltose was extremely slow, which was unsuitable for industrial practice.

Further, it was found that at a temperature above 130 ° C., not only the crystallization is slow, but also the coloring during the crystallization is remarkable, which is unsuitable as a method for producing crystalline α-maltose powder.

Therefore, in order to crystallize crystalline α-maltose, high-purity syrup having a water content of high-purity maltose of less than 10 w / w% is used.
It is important to crystallize in the presence of seed crystals while maintaining the temperature range of 50 ° C to 130 ° C. At this time, a method of making high-purity maltose a high-concentration syrup having a water content of less than 10 w / w% is, for example, heating a small amount of water with a commercial β-maltose hydrous crystal having a maltose content of 85 w / w% or more per solid matter. It may be dissolved to form a high-concentration syrup having a water content of less than 10 w / w%, or a high-purity maltose aqueous solution having a maltose content of 85 w / w% or more per solid matter obtained by saccharifying starch is concentrated under reduced pressure to obtain a water content. High-concentration syrup of less than 10w / w% may be used, and the water content in these high-purity maltose is 10w / w.
A high-concentration syrup droplet having a water content of less than 10 w / w% may be prepared by spray-drying an aqueous solution of w% or more and less than 35 w / w%.

In addition, to crystallize crystalline α-maltose in the presence of seed crystals, with respect to a high-concentration syrup solid of high-purity maltose, usually 0.001 w / w% or more and less than 100 w / w, preferably 0.1 It is sufficient if crystalline α-maltose can be crystallized by coexisting w / w% or more and less than 20 w / w% of crystalline α-maltose seed crystals, and as a method thereof, for example, water of high-purity maltose 10 w / w% Or crystallize by kneading seed crystals in a high-concentration syrup of less than 10 or high-purity maltose water content 10
Seed crystals are mixed with syrup of w / w% or more and less than 20 w / w%, and water content is applied by spray drying while the seed crystals do not dissolve or disappear.
Crystallize in high-concentration syrup drops of less than 10w / w%, or
Furthermore, high-purity maltose having a water content of 10 w / w% or more and 35 w / w% or less of syrup into a syrup droplet having a water content of less than 10 w / w% by a spray-drying method, etc. Can be appropriately selected.

In addition to the above method, it is also advantageous to promote crystallization under pressure. In particular, it is convenient to apply a pressure of about 5 kg / cm ² or more when crystallizing α-maltose and during eutectic. Therefore, a method for producing crystalline α-maltose powder, which requires pressure and compression, for example, by an extrusion granulator can be advantageously carried out.

It was also found that it is possible to advantageously carry out crystallization while promoting the crystallization of the musket during crystallization. The drying method can be appropriately selected under normal pressure, reduced pressure, or increased pressure, and a stationary state or a fluidized state.

The method for promoting the crystallization of these crystalline α-maltose has a content of the optical isomer α-maltose of the present invention of 55 w / w%.
The time to reach the above can be shortened to about 4/5 to 2/5, not only increasing the production efficiency of the crystalline α-maltose powder, but also extremely increasing the coloring degree of the crystalline α-maltose powder. It is advantageous as a method for mass production of reduced and high quality crystalline α-maltose powder.

Further, a method in which two or more of these methods are combined, for example, a eutectic by a method such as the above method from a high-concentration syrup having a water content of high-purity maltose of less than 10 w / w% to give an optical isomer α-
A maltose with a maltose content of more than 48w / w% is formed, and then it is molded into various shapes such as powder, strands, blocks, etc., and is aged while being crystallized and dried while being maintained in the temperature range of 50 ° C to 130 ° C. A method for producing a crystalline α-maltose powder having an isomer α-maltose content of 55 w / w% or more can also be carried out very advantageously.

As the aging condition, usually, in the temperature range of 50 ° C to 100 ° C, about 0.1 to 24 hours, in the temperature range of more than 100 ° C and 130 ° C, about 0.5 to 18 hours, preferably higher temperature,
It has been found that under severe conditions for a long time, the degree of coloring of the crystalline α-maltose powder obtained increases and the commercial value is impaired. During aging, crystallization under pressure and / or while drying promotes crystallization of crystalline α-maltose, and the aging time can be significantly shortened.
It is convenient as a method for mass producing crystalline α-maltose powder.

Further, as a method for producing a crystalline α-maltose powder having an optical isomer α-maltose content of 55 w / w% or more, for example, an extrusion granulation method, a block pulverization method, a spray drying method, a fluidized granulation method, etc. is there.

In the case of the extrusion granulation method, for example, while maintaining a high-concentration syrup having a water content of high-purity maltose of less than 10 w / w% in a temperature range of 50 ° C to 130 ° C, a seed crystal of crystalline α-maltose is added thereto. The mixture is kneaded and assisted to give a mass kit having a content of the optical isomer α-maltose of more than 48 w / w%, and the granulated mass kit or granular powder obtained by subjecting this to an extrusion granulator is heated at a temperature of 50 ° C to 130 ° C. Crystallized and aged while drying while maintaining the range, and the optical isomer α-maltose content was 55 w /
Collect w% or more crystalline α-maltose powder.

Further, high-concentration maltose water content of less than 10w / w% high-concentration syrup, extruded without coexisting seed crystals, granulated, contact the resulting high-concentration syrup droplets crystalline α-maltose seed crystals, While maintaining the temperature range of 50 ℃ ~ 130 ℃, while crystallizing and aging while drying, the optical isomer α-
A crystalline α-maltose powder having a maltose content of 55 w / w% or more can also be collected.

In the case of the block pulverization method, for example, a high-concentration maltose with a high-concentration syrup having a water content of less than 10 w / w% is taken in an auxiliary crystallizer, and while maintaining the temperature range of 50 ° C. to 130 ° C., crystalline α-maltose is added thereto. Seed crystals of (1) are mixed with each other to form a mass kit having a content of the optical isomer α-maltose of more than 48 w / w%.
C. to 130.degree. C. while crystallizing and solidifying while maintaining the temperature range, the resulting block is crushed with a cutting machine, a hammer mill, etc., dried and sieved to obtain the optical isomer α-maltose content.
55 w / w% or more of crystalline α-maltose powder is collected.

In the case of the spray drying method, for example, the water content of high-purity maltose is about 10 w / w% or more and less than 20 w / w% and the crystalline α-
Seed crystals of maltose are mixed and spray dried by a high-pressure nozzle method or a rotating disk method as quickly as possible so that the seed crystals do not dissolve and disappear to form syrup droplets with a water content of less than 10 w / w%. Crystallization aged while crystallizing and aging while keeping the temperature in the range of ℃ to 130 ℃, and collecting crystalline α-maltose powder having optical isomer α-maltose content of 55 w / w% or more.

Further, in the case of the fluidized granulation method, for example, a syrup having a water content of high-purity maltose of 15 w / w% or more and less than 35 w / w% is directed toward the seed crystals of crystalline α-maltose which is fluidized in advance. , Water content less than 10w / w% by spray-drying to form a high-concentration syrup droplet, and aging while crystallization while drying while maintaining this in the temperature range of 50 ° C to 130 ° C, the optical isomer α-maltose content is 55 w / w% or more of crystalline α-maltose powder is collected.

It is also advantageous to carry out continuous production of crystalline α-maltose by continuously turning a part of the crystalline α-maltose obtained as described above into a seed crystal.

The crystalline α-maltose powder having an optical isomer α-maltose content of 55 w / w% or more of the present invention produced in this manner is a white powder having an elegant and low sweetness, its water content is low, and substantially Anhydrous, usually by Karl Fischer
It is less than 3w / w%, preferably less than 2w / w%, and its fluidity is slightly different depending on the shape and size of powder particles, the difference in optical isomer α-maltose content, etc. Is.

The melting point is 121 to 125 of β-maltose hydrous crystal.
Much higher than ℃, 130 ℃ or more, especially in the case of crystalline α-maltose powder with an optical isomer α-maltose content of 60 w / w% or more, there is a risk of sticking or solidification at about 140 ℃ or more. No crystalline powder with sufficient fluidity.

The crystalline α-maltose powder thus obtained is
When this is contained in a water-containing material such as food, pharmaceuticals, cosmetics, industrial chemicals, etc., the water content contained therein is β-.
It was found that the maltose hydrated crystals were captured and fixed as water of crystallization and acted as a strong dehydrating agent for the hydrated substance.

Crystalline α-maltose is not only water-containing crystals (Hayashibara Co., Ltd., registered trademark Sanmalto) that are commercially available in the past, but not only water but also an organic acid aqueous solution, a salt aqueous solution, a protein aqueous solution, an emulsion, and an alcohol. It was found that it can be rapidly dissolved in a high concentration in various aqueous solutions such as an aqueous solution. This property is convenient for using crystalline α-maltose as a dehydrating agent to produce various dehydrated articles with reduced water content from various hydrates.

As the dehydrating agent of the present invention can be advantageously applied, when dehumidifying and drying the atmosphere in the moisture-proof container, further, heat-drying, water-containing substances that easily accompany deterioration in the process such as vacuum drying or water-containing difficult to dry From things etc. to high quality mask kit,
There are cases where a dehydrated article such as powder is manufactured.

When dehumidifying and drying, for example, not only can it be used to prevent moisture absorption of seasoned seaweed, cookies, etc.,
A powdery material that easily absorbs moisture and solidifies, for example, premixed powder such as pudding mix powder, hot cake mix powder, salt, sugar, powdered soy sauce, powdered miso, powdered sushi vinegar, powdered dashi stock, powdered composite seasoning, etc. Powder seasoning, powdered paprika, powdered garlic, powdered cinnamon, powdered nutmeg, powdered pepper, powdered sage and other powdered spices, powdered yeast extract, powdered milk, powdered yogurt, powdered cheese, powdered juice, powdered herbs, powdered vitamins, granules By mixing crystalline α-maltose with powdered material such as soup, granule broth, fish meal, blood meal, bone meal, powdered lactic acid bacteria agent, powdered enzyme preparation, and granule digestive agent, the relative humidity inside the packaging container can be controlled. Since it can be reduced and the adhesion and solidification of powdery substances can be prevented, it can also be used for the purpose of maintaining high quality with good fluidity immediately after production for a long period of time. It is possible.

When dehydrating a water-containing material, for example, an animal,
It can be advantageously used for dehydrating various hydrates such as plants, organs derived from microorganisms, tissues, cells, grinds, extracts, components, or preparations thereof.

For example, in the case of food, its raw materials or processed intermediates, raw fruits, juice, soy milk, sesame paste, nut paste, raw bean paste, gelatinized starch paste, flour dough and other agricultural products, sea urchin paste, oyster extract, sardine paste.

When the dried product is an enzyme, it can be advantageously used as a catalyst for processing foods, pharmaceuticals, industrial raw materials, etc., as a therapeutic agent, a digestive agent, etc., and also as an enzyme detergent.

As a method for containing crystalline α-maltose in a water-containing material, a known method such as kneading, kneading, dissolving, permeating, spraying, coating, spraying or pouring is appropriately used until the intended dehydrated article is completed. To be chosen.

The amount of crystalline α-maltose contained in the hydrate varies depending on the amount of water contained in the hydrate and the properties of the intended dehydrated article. If necessary, the hydrate is partially dehydrated by other known methods. Alternatively, crystalline α-maltose may be added after concentration, and it is usually 0.01 to 500 parts by weight, preferably 0.1 to 100 parts by weight with respect to 1 part by weight of the hydrate. At this time, in order to further improve the quality of the obtained dehydrated article, for example, food, pharmaceuticals, cosmetics, it is also advantageous to use an appropriate flavoring agent, coloring agent, flavoring agent, stabilizer, extender, etc. in combination. it can.

In particular, regarding the stabilizer, since the present invention is a strong dehydration method using crystalline α-maltose, it is not necessary to limit it to a low molecular weight compound such as an antioxidant, and it is conventionally difficult to dry it. High molecular compounds, for example, soluble starch, dextrin, cyclodextrin, pullulan, erucinan, dextran, xanthan gum, gum arabic, locust bean gum, guar gum, tragacanth gum, tamarind gum, galboxymethyl cellulose, hydroxyethyl cellulose, hydroxyethyl starch, pectin, agar. Substances such as, gelatin, albumin, and casein can also be advantageously used as stabilizers.

When using these water-soluble polymer compounds, for example,
In a liquid or paste-like hydrate, a water-soluble polymer compound is uniformly dissolved in advance, and then crystalline α-maltose is mixed therein, and the resulting mixture is uniformly mixed by a method such as kneading to give a fine β- A dehydrated article obtained by precipitating maltose hydrous crystals is obtained. In this product, the fragrance component derived from a hydrate, the active ingredient, etc. are coated with a film of a water-soluble polymer compound, or encapsulated together with fine β-maltose hydrated crystals in microcapsules surrounded by the film. In addition, when cyclodextrin is used, it forms an inclusion compound, etc., and its volatilization and quality deterioration are prevented, so that it is extremely excellent in the stable retention of the aroma component derived from the hydrate and the active component. As cyclodextrin,
It is not limited to high-purity ones, and low-purity cyclodextrins that are difficult to dry and difficult to powder, for example, starch syrup partial hydrolyzate containing various cyclodextrins together with a large amount of maltodextrin is also advantageously used. it can.

Various methods can be adopted as the method for producing the dehydrated article of the present invention, especially the powdered article. For example, crystalline α-maltose is added to a water-containing substance having a relatively high water content such as food, pharmaceuticals, cosmetics, raw materials or processed intermediates thereof to reduce the water content.
30 w / w% or less, preferably about 5 to 25 w / w%, after uniformly containing it in a bat for about 1 to 10 days, about 10
It is allowed to stand at -50 ° C, for example, room temperature, to be converted into β-maltose hydrous crystal, to be solidified into, for example, a block, and this may be manufactured by a method such as cutting and crushing. If necessary, a drying step, a classification step, etc. can be added after the powdering step such as cutting and crushing.

Alternatively, the powder product can be directly produced by a spraying method or the like. For example, while flowing the crystalline α-maltose powder, a predetermined amount of a liquid or pasty water-containing substance is sprayed and brought into contact with the powder to granulate it, and then aged at about 30 to 60 ° C. for about 1 to 24 hours. Or to convert it into β-maltose hydrous crystals, or by mixing crystalline α-maltose with a liquid or pasty hydrous material, kneading, etc., immediately or by starting conversion to β-maltose hydrous crystals. A method of producing a powdered product by aging the powdered product obtained by spraying in the same manner and converting it to β-maltose hydrous crystals is suitable as a mass production method.

In the case of this spraying method, in order to promote the conversion of crystalline α-maltose into β-maltose hydrous crystals, crystalline α-maltose is used.
It is also advantageous to coexist with a seed crystal of β-maltose hydrous crystal of about 0.01 to 10 w / w% with respect to maltose to shorten the aging period. If necessary, it is optional to use a known drying method together with the use of a dehydrating agent. The powdered dehydrated article thus obtained may be used as it is or, if necessary, as a filler, an excipient, a binder,
It is also possible to freely use it in combination with a stabilizer and the like, and further to form it into an appropriate shape such as granules, tablets, capsules, rods, plates and cubes.

In addition, foods such as peanuts, almonds, hard candy, and molded products such as granules and pharmaceutical intermediates such as plain tablets are used as cores, and crystalline α-maltose of about 70 to 95 w / w is added to the core.
% Aqueous solution, preferably an aqueous solution in which an appropriate amount of a binder such as a water-soluble polymer is allowed to coexist, and then converted into β-maltose hydrous crystals and crystallized to produce a sugar-coated article can be advantageously carried out.

Further, crystalline α-maltose is mixed with a high-moisture hydrate, which is contained by a method such as kneading, when crystalline α-maltose is converted into β-maltose hydrous crystals and dehydrated, β
Expands its volume as it transforms into maltose hydrous crystals. When the expansion is remarkable, it reaches about 1.5 to 4.0 times. In this way, when expanded and solidified, the hardness is lower than that with less expansion, it is easier to pulverize, the abrasion of the cutting machine, crusher, etc. is less, and the power consumption for power consumption is also low. It has features that can save a lot of money.

Further, by utilizing this expansion phenomenon, dehydrated articles of various shapes can be manufactured. For example, in a plastic container having various shapes such as flowers, birds, fish, dolls, etc., a high water content substance containing crystalline α-maltose is taken and left at room temperature for about 5 to 90 hours to expand, By solidifying, dehydrated articles of various shapes can be obtained. If necessary, in order to further promote this expansion, a solvent such as an alcohol that easily vaporizes, a foaming agent that generates carbon dioxide gas, etc. may be contained together with the crystalline α-maltose, and slightly heated.
It may also be exposed to a steam atmosphere in order to accelerate the conversion to β-maltose hydrous crystals and reduce the time.

The dehydrated articles of various shapes thus obtained can enjoy the shapes thereof, and can be advantageously used for foods such as confectionery and favorite foods, as well as cosmetics and pharmaceuticals.

In addition, starch generally requires a large amount of water for its swelling and gelatinization. Therefore, gelatinized starch is extremely susceptible to microbial contamination. Crystalline α-maltose can be advantageously used as a dehydrating agent for such gelatinized starch.
For example, gelatinized starch such as fertilizer can contain crystalline α-maltose and convert it into β-maltose hydrous crystals, whereby the water content is substantially reduced and microbial contamination can be prevented.

In addition, crystalline α-maltose mixes easily and uniformly with gelatinized starch and also acts as an anti-aging agent. Therefore, the product life of various processed foods containing gelatinized starch can be significantly extended. You can

Further, crystalline α-maltose is, for example, peeled banana, peeled orange, sliced steamed rice, opened horse mackerel, raw noodles, boiled noodles, rice cake, etc. In some cases, crystalline α on its surface
-Sprinkle maltose powder to convert it to β-maltose hydrous crystals, substantially reduce the water content on the surface, improve the shelf life of these foods, and improve the quality. It can be advantageously used as an improving agent. At this time, if necessary, for example, lactic acid, citric acid,
It is also free to further extend the product life by using ethanol or the like in combination, vacuum packaging, gas filling packaging, refrigeration, or the like.

Further, crystalline α-maltose can be obtained, for example, from Japanese Examined Patent Publication No. 52-48.
Unlike the maltose syrup powder disclosed in Japanese Patent Publication No. 198, it has a high affinity for alcohol. Due to this property, it can be advantageously used as a dehydrating agent for water contained in alcohols such as methanol, ethanol, butanol, propylene glycol, glycerin, polyethylene glycol, or alcohol-soluble substances. For example,
Dehydrated sake such as sake, shochu, wine, brandy, whiskey, vodka, etc. dehydrated with crystalline α-maltose, and β-maltose hydrous crystals produced retain the active ingredient, aroma, etc. Can be advantageously manufactured. The powdered liquor thus produced can be used for confectionery, premixes, etc., and can be reconstituted with water for drinking.

In this case, the crystalline α-maltose can exert not only the effect as a dehydrating agent and a stabilizer but also the effect as a high-quality sweetness, a body, an appropriate viscosity-imparting agent and the like.

Further, an alcohol solution such as iodine is mixed with crystalline α-maltose, and an aqueous solution containing a water-soluble polymer or the like is added to the mixture to convert it into β-maltose hydrous crystals, thereby stabilizing the active ingredients such as iodine. It is also possible to advantageously carry out production of a musket-shaped salve or the like which retains and has an appropriate viscosity, extension and adhesiveness. In addition, crystalline α-
Although maltose is a hydrophilic sugar, it exhibits surprisingly large lipophilicity.

From this property, crystalline α-maltose is an oil-soluble substance,
It can also be advantageously used as a dehydrating agent for water contained in emulsions and latexes.

Oil-soluble substances, for example, soybean oil, rapeseed oil, hot oil, sesame oil, safflower oil, palm oil, cocoa butter, beef tallow, lard, chicken oil, fish oil, fats such as hydrogenated oil, citrus essential oil, flower essential oil, spice Oil-soluble spices such as oil, peppermint oil, spearmint oil, cola nut extract, coffee extract, β-carotene, paprika pigment, anatto pigment, oil-soluble colorants such as chlorophyll, liver oil, vitamin A, vitamin B ₂ butyrate , Vitamin E, Vitamin K, Vitamin D and other oil-soluble vitamins, estrogen, progesterone, androgen, prostaglandin and other oil-soluble hormones, linoleic acid, linolenic acid, arachidonic acid, eicosapentaenoic acid, docosahexaenoic acid and other highly unsaturated compounds Desorption that strongly captures even a small amount of water contained in fatty acids, etc. It can be advantageously used as agents.

The oil-soluble substance dehydrated by crystalline α-maltose is
It is of high quality and has the characteristic of being less susceptible to quality deterioration such as hydrolysis and deterioration.

Further, a crystalline α-maltose is impregnated with a water-containing oil-soluble substance, an emulsion, a latex, etc., and the crystalline α-maltose is converted into β-maltose hydrous crystals by mixing and the like, and powdered oil and fat, spices, flavors, and coloring Food, cosmetics, etc.
It is also possible to advantageously carry out the production of pharmaceuticals such as powdered vitamins and hormones.

In this case, the crystalline α-maltose acts not only as a dehydrating agent but also as a stabilizer, a retaining agent, an excipient, a carrier or the like after being converted into β-maltose hydrous crystals.

Crystalline α-maltose is also advantageously used in the case of foods containing oil-soluble substances such as chocolate and sand cream that dislike moisture. In this case, not only as a dehydrating agent, but also having good processing suitability, melting in the mouth, flavor and the like is utilized. Furthermore, the obtained product has the characteristic that its high quality can be stably maintained for a long period of time.

As described above, the present invention was achieved by finding that crystalline α-maltose strongly dehydrates the water content of various hydrates, and the crystalline α-maltose is used as a dehydrating agent. By doing so, from a liquid or paste-like water-containing substance, its flavor and aroma are not deteriorated, and high-quality food products and cosmetics with reduced water content are decomposed, and their active ingredients and activities are decomposed and reduced. It is possible to advantageously produce high-quality pharmaceuticals, cosmetics, etc. with reduced water content without causing the above.

Further, crystalline α-maltose is not only the special case described above, but also a natural sweetener inherent in maltose, and there is no concern about tooth decay induction, an increase in blood cholesterol, and the like. Since it also has properties such as imparting, imparting luster, viscosity and water retention, it can be advantageously used in the production of foods, pharmaceuticals, cosmetics and the like.

Further, crystalline α-maltose is a nutrient that is originally utilized for metabolism of maltose.

When used parenterally as an injection, etc., it becomes isotonic at twice the concentration compared to glucose, so calorie supplementation can be performed at twice the concentration, and large calories during surgery are required. It is suitable as a nutritional supplement for treatment.

Next, other examples of use will be described.

Moreover, when the X-ray diffraction patterns of the respective samples were examined with time, and compared, there was no change in anhydrous glucose, sugar, and β-maltose hydrous crystals. However, it was found that crystalline α-maltose changes by trapping water, is converted into β-maltose hydrous crystals with about 5% of water, reaches equilibrium water, and is stabilized.

Similarly, the same crystalline α-maltose was placed in an atmosphere of 25 ° C., which was conditioned to a relative humidity of 92%, and its water content (%) was measured with time. It was found that even after conversion to water-containing crystals, water was taken in, and equilibrium was reached and stabilized at about 18% water. Also in this case, the phenomenon of maintaining the powder state and getting wet or flowing was not observed.

From this fact, the prepared sand cream not only reduces the relative humidity of the atmosphere by trapping the moisture in the atmosphere and dehydrating it by storing it in a moisture-proof container by sandwiching it between cookies and biscuits, for example. ,
It was also found that the sand cream itself can be stably maintained for a long period of time without degrading its quality.

Experiment 7 Comparison of sugar with gelatinized starch Dissolve 400 g of glutinous rice flour with 600 ml of water, pour it into a wooden frame covered with leak cloth, and steam this at 105 ° C for 10 minutes to obtain gelatinized starch.

To this, 800 g of crystalline α-maltose prepared in Test No. 5 of Experiment 1 or β-maltose hydrous crystal which is a raw material thereof was mixed with a mixer, and when the mixture became uniform, further starch syrup was added.
200 g was added, and the mixture was thoroughly kneaded to form a fertilizer, which was then lightly dried with warm air at 40 ° C for 2 hours to obtain a fertilizer.

When this product was left open in a room at 25 ° C and left for 12 days, black mold colonies were observed in those that used β-maltose hydrous crystals, but those that used crystalline α-maltose were observed. , No microbial contamination was observed even after 20 days.

Also, after cutting the thing after 20 days, when observing the cross section, the one using crystalline α-maltose, although the surface layer portion is slightly hardened and crystals are precipitated, the inside is the same as immediately after production. It was semi-transparent and had moderate gloss and viscosity.
From the X-ray diffraction pattern, the crystals in the surface layer were found to be crystalline α-maltose converted into β-maltose hydrous crystals.

On the other hand, in the case of using the β-maltose hydrous crystal, not only the mold was generated on the surface but also the cross section was clouded over the whole layer and was not glossy.

As a result, it was found that crystalline α-maltose acts as a dehydrating agent for gelatinized starch, prevents microbial contamination, and further prevents aging of gelatinized starch.
