Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a fine cellulose-containing composite. More specifically, containing specific fine cellulose and low-viscosity water-soluble dietary fiber, the texture, shape retention,
The present invention relates to a fine cellulose-containing composite that is excellent in functions such as fluidity of liquid food, and is also excellent in dietary fiber effect and fat and oil substitute effect.

[0002]

2. Description of the Related Art Conventionally, cellulose is used to impart suspension stability,
It has been blended in foods for various purposes such as emulsification stability imparting, shape retention imparting, cloudy imparting, and dietary fiber intake. However, if cellulose is used alone as a stabilizer or the like,
In some cases, the effect of addition was insufficient, or a slightly grainy texture was felt. Also, the action of dietary fiber in the intestinal tract is different between water-insoluble dietary fiber and water-soluble dietary fiber, and since natural dietary fiber is usually a complex of water-insoluble and water-soluble dietary fiber, It is said that the combination of both is preferable. However, there is no material for dietary fiber that has a low viscosity suitable for incorporation into foods, has a low viscosity, has a good texture and is stable.

Japanese Patent Publication No. 57-14771 discloses a complex containing microcrystalline cellulose, a dispersant (gum) and a disintegrant in a specific ratio. However, depending on the type of gum, the viscosity may be different. Since it is expensive, it may have a heavy texture with a pasty feel. For example, "Avicel" (trade name) RC-591, which is commercially available as a crystalline cellulose preparation.
(Manufactured by Asahi Kasei Co., Ltd.) contains carboxymethylcellulose sodium as a dispersant together with crystalline cellulose, but has a viscosity of 1 when dispersed in water at a concentration of 3%.
It was as high as 200 mPa · s.

Japanese Patent Publication No. 6-75474 describes a composition comprising microcrystalline cellulose and galactomannan gum. However, the galactomannan gum used in this composition is a normal gum that has not been subjected to a decomposition treatment, and because it acts as a binder for microcrystalline cellulose, it only swells even when the composition is stirred in water, The composition particles do not disintegrate and maintain their original state. Therefore, this composition gives a fat-like mouthfeel and is said to be suitable as a fat substitute for foods, while having low suspension stability in water.

JP-A-6-135838 describes an invention relating to an oral tube feeding composition containing crystalline cellulose as a water-insoluble dietary fiber and a guar gum enzymatic degradation product as a water-soluble dietary fiber. However, in this composition, the crystalline cellulose and the enzymatically decomposed product of guar gum do not form a complex, and are merely added separately to form the composition, so that the texture of crystalline cellulose can be suppressed. It was not sufficient, and the flowability of the tube was not sufficient.

Japanese Unexamined Patent Publication Nos. 7-173332 and 7
No. 268129 discloses that particles having a particle size of 10 μm or more are 4
A composite comprising fine cellulose and a hydrophilic substance and / or a water-soluble gum is described, which is 0% or less and has a colloid fraction of 65% or more, which is one measure of the amount of fine particles. The hydrophilic substance is polydextrose, and the water-soluble gum is xanthan gum. However, these have a high colloidal fraction and thus have a high viscosity. When added to foods such as beverages in an amount of 1% or more, the texture becomes heavy, and when they are used for tube liquid foods, they flow down at a sufficient speed. It was difficult to do.

[0007] On the other hand, dextrins are exemplified as hydrophilic substances in the above-mentioned JP-A-7-173332 and JP-A-7-268129. Dextrin refers to a group of intermediate products produced when partial hydrolysis of starch by the action of acid, enzyme, heat, or other action, and in the commercial sense, it is often the roasted dextrin produced by the dry method (Sakurai Yoshiyoshi). Edited by People, "Comprehensive Food Dictionary (6th Edition)" (published by Doshoin, p617-618 (1989)). Since the starch hydrolyzate is described together with the dextrins in this patent specification, the dextrins mean roasted dextrins. By the way, roasted dextrins include white and yellow dextrins that are decomposed by heating with an acid as a catalyst, and British gums that are decomposed only by heat without using an acid, and these are known to have indigestible components. . However, the maximum content of indigestible ingredients is 4
It is about 0%, and more than half is digestible. (K. Oh
kuma et. al. , Denpun Kagak
u, 37 (2), p107-114 (1990)), that is, those generally known as dextrins were digestible. However, since the indigestible dextrin used in the present invention is indigestible as described below, it is a substance different from the dextrins used in the present invention, and the indigestible dextrin of the present invention in the present invention is because it is indigestible. Meaning as a dietary fiber material.

In Japanese Patent Application Laid-Open No. 7-70365, a particle size of 10
There is a description of a complex of fine cellulose and polydextrose, in which particles having a size of μm or more are 40% or less and a colloid fraction is 50% or more. Although this composite has a low viscosity, it lacked long-term suspension stability. In addition, since the cellulose particles are fine, they easily interact with milk proteins and the like, and polydextrose has a poor effect of suppressing them, so that the system tends to aggregate. Further, although the invention also describes the use of dextrins, it was a substance different from the indigestible dextrin of the present invention for the same reason as described above.

[0009]

DISCLOSURE OF THE INVENTION The present invention not only has a low viscosity when dispersed in water and is excellent in suspension stability, but also has a texture, suspension stability, shape-retaining property, and tube-fed liquid food. It is an object of the present invention to provide a fine cellulose-containing complex having excellent functions such as fluidity and the like, and having the effects of both water-insoluble and water-soluble dietary fiber, and a food containing the same.

[0010]

Means for Solving the Problems The present inventors have found that a complex containing specific fine cellulose and indigestible dextrin has a low viscosity when dispersed in water, and the average particle size of fine cellulose is small.

The present invention will be described in detail below.

The fine cellulose-containing composite of the present invention is
It is not simply a mixture of fine cellulose powder and indigestible dextrin powder, but one particle contains one or more fine cellulose particles, indigestible dextrin and other components, and fine cellulose particles It means a dry powder consisting of particles having a structure in which the indigestible dextrin is present around, and a group of the particles.

When the fine cellulose-containing composite of the present invention is stirred in water, it does not disperse in water in the form of the composite, but the composite disintegrates and disperses in the form of individual fine cellulose particles. It is a feature.

The average particle size of the fine cellulose when the fine cellulose-containing composite is agitated and dispersed in water at a concentration of 1% is required to be 30 μm or less. The ratio of particles having a particle size of 10 μm or more in the particle size distribution at this time is 8
It is preferably 0% or less. More preferably, the average particle size is 20 μm or less, and the ratio of particles having a particle size of 10 μm or more is 70% or less. More preferably, the average particle size is 3 to 10 μm, and the ratio of particles having a particle size of 10 μm or more is 50% or less. If the average particle size exceeds 30 μm,
When eating, a rough feeling is felt in the mouth, and functions such as stability are deteriorated. If the average particle size is smaller, the graininess tends to be improved, but if it is less than 3 μm, the colloid fraction increases and the viscosity may increase, which is not preferable.

Further, the fine cellulose-containing composite of the present invention has a low viscosity, and it has a low viscosity when measured in water at a concentration of 3%, preferably 300 mPa.
It means s or less. Viscosity is 300 mPa · s
If it exceeds, the texture tends to be heavy. In particular, when blended into a tube liquid food, at a flow rate above a certain value,
Specifically, when a liquid food containing about 1.5% of the composite is flowed down in a tube with an inner diameter of 1 mmφ or less, 200 g
It becomes difficult to make it flow down at a flow velocity of / hr or more,
In addition, the clamp is squeezed to keep the flow velocity constant, for example, 1
When adjusted to 70 g / hr, the liquid food tends to be clogged in the clamp part. The viscosity is preferably 100 mPa ·
s or less, and more preferably 50 mPa · s or less.

The indigestible dextrin means, for example, after heating starch in the presence of an acid to obtain roasted dextrin,
It is obtained by enzymatically decomposing or further fractionating with an ion exchange resin, and has an average molecular weight of about 500 to 3000 and glucose residues of α-1,
4, α-1,6, β-1,2, β-1,3, β-1,6
It is an indigestible substance with a branched structure, which is linked by a glucosidic bond and a part of the reducing end is levoglucosan (1,6-anhydroglucose). Examples of commercially available products "Pine Fiber" (trade name), such as "Fiber Sol 2" (trade name) (manufactured by Matsutani Chemical Industry Co., Ltd.) can be used. These are characterized by low water-soluble viscosity and being indigestible unlike ordinary starches.
Indigestible dextrin used in the present invention is characterized by showing a low viscosity when dissolved in water. When the indigestible dextrin is dissolved in 10% concentration, the viscosity of the aqueous solution is 300 mPa · s or less, preferably 100 mPa · s.
Or less, particularly preferably 10 mPa · s or less. Starch hydrolysates (HCS), dextrins, and maltodextrins are generally used as starches that give low-viscosity aqueous solutions, but they are digestible and different from the indigestible dextrins used in the present invention. . As the indigestible dextrin used in the present invention, a fiber containing a dietary fiber component, that is, an indigestible component of 50% or more is used, and more preferably 70% or more.

Xanthan gum has a glucose residue β-
A trisaccharide having a main chain having a molecular structure equivalent to that of cellulose, which is linearly linked by a 1,4-glucoside bond and to which α-D-mannose, β-D-glucuronic acid, and β-D-mannose are bonded, As a side chain, it has a structure in which every other glucose residue in the main chain is bonded. An acetyl group and a pyruvate group are bound to this trisaccharide. The molecular weight is about 1 million or more.

Gellan gum comprises 1,3-bonded β-D-glucose, 1,4-bonded β-D-glucuronic acid, 1,
4-bonded β-D-glucose, 1,4-bonded α-L
-A linear polymer having four molecules of rhamnose as a structural unit, a native glyceryl group having 1 residue and an acetyl group having an average of 1/2 residue bonded to the 1,3-bonded glucose residue. It is called a type gellan gum.
The molecular weight is about 600,000 to 700,000. As a commercially available product, "Kelcogel" (trade name) LT-100 (San-ei Gen FFI Corporation) or the like can be used.

The fine cellulose-containing composite of the present invention contains 20 to 99% by weight of fine cellulose and 1 to 80% by weight of indigestible dextrin. If the fine cellulose is less than 20% by weight, the effect as a stabilizer such as imparting shape retention during baking of baked confectionery is not sufficient. When the content of fine cellulose exceeds 99% by weight, it is not preferable in terms of texture because it gives a rough feel or a harsh feel. When the indigestible dextrin is less than 1% by weight, it is difficult to disperse the composite in individual fine cellulose particles even if the composite is stirred in water. When the content of indigestible dextrin exceeds 80% by weight, not only the effect as a stabilizer is not sufficient, but also a sticky texture is obtained, which is not preferable.

The fine cellulose-containing composite of the present invention preferably contains 40 to 90% by weight of fine cellulose and 10 to 60% by weight of indigestible dextrin, and particularly preferably 50 to 85% by weight of fine cellulose. 15 to 50% by weight of digestible dextrin.

The fine cellulose-containing composite of the present invention comprises:
In addition to fine cellulose and indigestible dextrin, monosaccharides, oligosaccharides, sugar alcohols, starches, soluble starch, starch hydrolysates, oils and fats, proteins, salt, salts of various phosphates, emulsifiers, It is free to appropriately mix ingredients that can be used in foods, such as a viscosity stabilizer, an acidulant, a flavor and a dye. In particular, in order to adjust the dispersion state of the complex, xanthan gum, carrageenan, sodium carboxymethyl cellulose, gellan gum, etc., thickening stabilizers used in food, sugars, soluble starch,
It is also effective to blend starches such as starch hydrolysates, galactomannan degradation products, pectin degradation products, and water-soluble dietary fibers such as polydextrose alone or in combination. Note that these components may be added at the time of manufacturing the composite or may be added after manufacturing the composite. The amount to be blended should be appropriately determined depending on the balance between functions such as stability and viscosity. For example, when xanthan gum is blended as a stabilizer, 0.1 to 3% or less and gellan gum of 1% or less can provide preferable results. In particular, the compounding amount thereof is preferably 0.1 to 2.5% by weight based on the composite.

The fine cellulose-containing composite of the present invention preferably has a low colloid fraction. The higher the colloid fraction, the higher the viscosity. Preferably 85% or less,
More preferably less than 65%, particularly preferably 5-50%
Is.

The composite of fine cellulose and indigestible dextrin in the present invention is not a mixture of fine cellulose and indigestible dextrin in a powder state, but contains fine cellulose and indigestible dextrin in water. It is obtained by mixing in a state, that is, slurry, paste, gel or cake, and then drying. It is essential that the surface of the fine cellulose particles is well blended with the indigestible dextrin by mixing in the presence of water. After this, a drying step probably causes an interaction between the fine cellulose particles and the indigestible dextrin, and the surface of the fine cellulose particles individually dispersed when stirred in water has the indigestible dextrin. It is presumed that some of the
As a result, the aqueous dispersion of the composite has a reduced viscosity as compared to a mixture of them, and the clogging at the clamp portion when the tube is flowed down is reduced. The water content of the mixture before drying is preferably about 30% by weight or more of the total weight of the mixture. When the water content is low, it takes time to sufficiently mix the fine cellulose and the indigestible dextrin, which is not preferable. A more preferable water content is about 50% by weight or more.

The method for producing the fine cellulose-containing composite of the present invention will be specifically described.

The fine cellulose-containing composite of the present invention is, for example, acid-hydrolyzed, alkali-oxidized, enzyme-degraded or steam-exploded of a cellulosic material such as wood pulp, refined linter, regenerated cellulose, grain or fruit-derived plant fiber. Depolymerization treatment by John decomposition, hydrolysis by subcritical water or supercritical water, or a combination thereof to obtain an average degree of polymerization of 30 to 375, and then mechanical shear (shearing force) is applied to grind, It can be obtained by making fine cellulose, adding indigestible dextrin, mixing and drying. After the indigestible dextrin is added to the depolymerized cellulose, mechanical shearing is performed to simultaneously perform grinding and mixing, that is, so-called wet co-grinding, followed by drying to obtain a composite containing fine cellulose. Particularly preferred. Further, the fine cellulose-containing composite of the present invention, without subjecting the cellulosic material to chemical treatment,
Alternatively, after subjected to a weak chemical treatment, wet shearing by applying mechanical shear, or can be obtained by crushing, fine fibrous cellulose made from wood pulp or bacterial cellulose, or The powdery cellulose may be obtained by mixing and / or grinding powdery cellulose with indigestible dextrin in the presence of water and then drying to obtain a complex containing fine cellulose.

The wet grinding machine is freely selected depending on the amount of water present in the system and the degree of fineness of cellulose.

For example, when sufficient mechanical shear is applied to obtain fine cellulose having an average particle size of 8 μm or less,
In addition to medium agitation mills such as a wet vibration mill, a wet planetary vibration mill, a wet ball mill, a wet roll mill, a wet coball mill, a wet bead mill, a wet paint shaker, and the like, a high pressure homogenizer and the like are used. As the high-pressure homogenizer, a type in which the slurry is introduced into a fine orifice and face-to-face collision at a high flow rate at a high pressure of about 500 kgf / cm ² or more is effective. The optimum grinding concentration when using these mills varies depending on the model, but is generally 3 to 2
A solid content concentration of about 5% by weight is suitable.

When mechanical shear is applied to obtain fine cellulose having an average particle size of 5 to 30 μm, a slurry-like system having a solid content of about 3 to 30% by weight is ground. As the colloid mill, a continuous ball mill, a homogenizer, a homomixer, a grinder such as a propeller stirrer, or a mixer can be used. Further, a kneader, a liquor machine, an extruder or the like can be used to grind a cake-like material having a solid content concentration higher than that of about 20 to 60% by weight. The microfibrous cellulose is obtained by passing the cellulosic material suspension several times with a high pressure homogenizer at a pressure of 50 kgf / cm ² or more to disaggregate the fiber diameter to about 0.01 to 1 μm, or It can be obtained by treating a suspension of a cellulosic material with a medium stirring mill several times. For the purpose of the present invention, these models can be used alone, or two or more models can be used in combination.

A known method may be used for drying the mixture of fine cellulose and indigestible dextrin, but in practice, the optimum method should be selected depending on the water content and the condition of the object to be dried. For example, in the case of a slurry, a spray drying method, a drum drying method, an alcohol precipitation method and the like can be used. Examples of the mud-like material and rice cake-like material include a tray drying method, a belt drying method, a fluidized bed drying method, a freeze drying method, and a microwave drying method. From the viewpoint of improving the solubility and redispersibility of the complex in water, the method of forming a slurry and spray-drying is preferable. From the viewpoint of reducing the drying cost, the alcohol precipitation method, the pressing method, the tray drying method capable of drying in a state where the solid content is high, and the fluidized bed drying method are preferable. The upper limit of the water content after drying is preferably 15% by weight or less in consideration of handleability and stability over time. It is particularly preferably 10% by weight or less. It is more preferably 6% by weight or less.

Since the dried product obtained by the drum drying method, the tray drying method, the belt drying method, etc. is obtained in the form of flakes or lumps, it can be prepared by an appropriate method such as an impact crusher or a jet mill crusher. It is preferable to pulverize and pulverize so as to pass through a sieve having an opening of 425 μm almost completely.

The fine cellulose-containing composite of the present invention can be used in various foods. Examples include coffee, black tea, matcha tea, cocoa, soup powder, juice and other favorite beverages, raw milk, processed milk, lactic acid bacteria beverages, dairy beverages such as soy milk, calcium-fortified beverages and other nutrient-enriched beverages, and dietary fiber-containing beverages. Beverages including, ice cream, ice milk,
Ice cream such as soft cream, milk shake, sorbet, butter, cheese, yogurt, coffee whitener, whipped cream, custard cream, pudding and other dairy products, mayonnaise, margarine, spread, shortening and other oil-processed foods, etc. Soups, stews, sauces, sauces, dressings and other seasonings, various spices typified by kneading, jams, various fillings typified by flower paste, gel-paste foods containing various kinds of anions and jellies , Bread, noodles, pasta, pizza, cereal foods including various premixes, candy, cookies, biscuits, hot cakes, chocolate, Japanese and Western confectionery including mochi, kamaboko, fish paste products represented by Hanpen, etc., For ham, sausage, hamburger, etc. Represented by livestock products, cream croquette, Chinese for Anne, gratin, various prepared foods such as dumplings, salted, delicacies such scum 漬等 a liquid food acids and pet foods, and the like, such as intubation liquid diet.

The fine cellulose-containing composite of the present invention has a suspension stabilizer, an emulsion stabilizer, a thickening stabilizer, a foam stabilizer, a cloudy agent, a texture-imparting agent, a fluidity-improving agent and a retention agent in these applications. It acts as a low calorie base such as a shaping agent, a water separating agent, a dough modifier, a powdering base, a dietary fiber base, and a fat / oil substitute. Further, the effects of the present invention are exhibited even when the above-mentioned foods have different forms or processing methods for preparation at the time of use, such as retort foods, powdered foods, frozen foods, and microwave foods.

When the fine cellulose-containing composite of the present invention is used in foods, it exhibits a low viscosity and the fine cellulose particles are small, so that it is refreshing and easy to pass through the throat at the time of eating, and the rough feeling is reduced. It has an excellent feature that it has a good texture.

In particular, the fine cellulose-containing composite of the present invention is suitable as a dietary fiber material for tube-fed liquid foods. At present, there is an attempt to mix water-soluble and water-insoluble dietary fibers in tube-fed liquid foods, and some of them are actually commercialized, but they do not always have sufficient physical properties as described below. . In other words, the tube-fed liquid food is to be administered to the human body through a tube, and it is necessary to have a property of flowing down at a constant flow rate at a considerably low speed for a long time.
In some cases, the water-insoluble component is clogged in the clamp that controls the flow rate. At present, the clamp is sometimes opened to administer the drug while clearing the blockage. The fine cellulose-containing composite of the present invention has a low viscosity and has a property that fine cellulose particles are hard to aggregate. Therefore, when it is added to a tube liquid food, the clamp portion is hardly clogged. In addition, since it contains water-soluble and water-insoluble dietary fiber, it has extremely excellent properties as a dietary fiber material for tube-fed liquid foods.

When the fine cellulose-containing composite of the present invention is used in foods, the same equipment as that generally used in the production of each food is used to prepare the main ingredients of the food and, if necessary, the same. , A fragrance, a pH adjuster, a thickening stabilizer, salts, saccharides, oils and fats, proteins, an emulsifier, an acidulant, a pigment, and the like, and the operation such as mixing, kneading, stirring, emulsifying, and heating may be performed. .

The content of the fine cellulose-containing composite of the present invention in the food varies depending on the kind of the food and the like, but is preferably about 0.01 to 15% by weight based on the whole food. When mainly considering the function as a stabilizer, about 0.02 to 3% by weight is preferable. Further, when considering mainly the use as a dietary fiber material (including a tube liquid food application) and an oil and fat substitute material, about 0.5 to 15% by weight is preferable.
