Abstract

PURPOSE:To obtain the title composition which, when added as e.g. a stabilizer to food, a medicine, etc., can give thereto an edibility fit for swallowing by mixing finely divided cellulose with a hydrophilic substance to form a mixture which, when redispersed in water, can give a dispersion in which the proportion of particles of a specified size or larger is a specified % or smaller, and the proportion of a colloid fraction is a specified % or above. CONSTITUTION:The composition is dry one which comprises 50-95wt.% finely divided cellulose and 5-50wt.% hydrophilic substance and which, when redispersed in water, can give a dispersion in which the proportion of particles having a size of 10mum or above is 40% or below, and the proportion of a colloid fraction is 50% or above. This composition, when agitated in water, can disperse in the form of the initial finely divided cellulose particles and therefore does not give any feeling of coarseness, which, when dispersed in water, can give an edibility fit for swallowing and functions as a stabilizer owing to the colloidal properties of the finely divided cellulose. This composition is effective as a suspension stabilizer, an emulsion stabilizer, a thickening stabilizer or the like used in fields wherein uniform dispersibility and long-term stability of this property are necessary, such as fields of food, medicines, cosmetics and coating materials.

[0001]

FIELD OF THE INVENTION The present invention relates to a dry composition capable of forming a cellulose colloid, which is used for foods, pharmaceuticals, cosmetics,
In a wide range of fields such as paints, ceramics, resins, catalysts, and other industrial products, suspension stabilizers, emulsion stabilizers, thickening stabilizers, and other stabilizers, texture imparting agents, cloudy agents, abrasives, dietary fibers, oils and fats.

2. Description of the Prior Art As water-dispersible composites mainly composed of cellulose, which have been used for the above-mentioned purposes, for example, Japanese Patent Publication Nos. 56-31094 and 57-14771.
Describes a water-dispersible composite in which microcrystalline cellulose is combined with a dispersant and a disintegrant. However, the commercial product Avicel <registered trademark> RC (Asahi Kasei Kogyo Co., Ltd.), which is said to have been created based on these technologies, contains a considerable amount of non-colloid parts, and is measured by a laser diffraction particle size distribution analyzer. It is known that the average particle size is about 10 μm. Therefore, it has been a problem that some kinds of foods and cosmetics give a feeling of roughness and the function as a stabilizer is not always sufficient.

To solve this problem, finely divided cellulose may be used to form a composite. However, cellulose forms strong hydrogen bonds between the surfaces of the cellulose during drying, and forms a dense and extremely strong structure that is difficult to redisperse in water, and this tendency is remarkable especially in the case of finer particles. In Japanese Patent Application No. 4-259396, water-soluble gums are blended to redisperse the fine cellulose, and the mixture is completely dispersed in the presence of 75% by weight or more of the total weight of water and then dried to obtain a composite. However, when water-soluble gums are blended, there are problems such as an increase in viscosity and deterioration of throat and texture.

[0004]

INDUSTRIAL APPLICABILITY The present invention can be used in a wide range of foods, pharmaceuticals, and industrial products by redispersing a dry composition containing fine cellulose in water without causing an increase in viscosity. It is designed to fully exhibit its function as a stabilizer for high-level suspension, dispersion and emulsification.

That is, according to the present invention, when a dry composition containing fine cellulose as a main component is redispersed in water, the dispersion mainly comprises a colloidal portion, has a high dispersion stability, and is rough. A fine cellulose composition redispersible in water, which does not feel and gives a good mouth-feeling texture, which can be used as a shape-retaining agent, a texture-imparting agent, a cloudy agent, an oil and fat substitute, etc. Is provided.

[0006]

The present invention relates to a dry composition for redispersion in water, which comprises 50 to 95% by weight of fine cellulose and 5 to 50% by weight of a hydrophilic substance. When redispersed in, the proportion of particles of 10 μm or more is 40
%, And the colloid fraction is 50% or more, which is a water-dispersible composition.

Japanese Unexamined Patent Publication (Kokai) No. 4-108347 discloses a food composition consisting of micronized cellulose and starch. This food composition is dried in a form in which cellulose particles enclose a part of starch, and hydrogen bonds between celluloses. It is described that, by fixing this wrapping structure, the elution of starch into water is suppressed. It is considered that the food composition is improved in water retention and oil retention due to the structure being fixed (not dispersed). The water-dispersible composition of the present application is a composition that can be dispersed in water by drying in a film as described below,
It is different from the food composition of JP-A-4-108347.

The present invention will be described in more detail below. According to our research, the main cause of graininess of cellulose fine particles is the amount of coarse particles. It is particles with a size of 10 μm or more that cause a particularly strong graininess, and this ratio is 40%.
Beyond the point, you will feel a foreign object on your tongue. The ratio of the particles of 10 μm or more to 40% or less corresponds to the average particle size of about 8 μm or less. It was also found that the smoothness felt by the tongue is consistent with the colloid fraction, which is a practical property for measuring colloidal cellulose.

That is, in order to obtain a smooth texture in an aqueous dispersion of a water-dispersible composition, it is necessary that the colloid fraction is 50% or more as an index when the dried composite is dispersed in water. is there. It is preferably at least 65%.
In order to eliminate graininess, 1 in the particle size distribution
It is necessary that the proportion of particles of 0 μm or more is 40% or less. The average particle size at this time is about 8 μm or less. Particularly preferably, it is necessary that the proportion of particles of 10 μm or more is 5% or less. The average particle size at this time is about 4 μm or less.

Here, the colloidal fraction means that when an aqueous dispersion of the composition is subjected to a constant centrifugal force, it floats without settling,
It is the weight ratio (%) of the solid content of the dispersed phase that is dispersed.
That is, it is the ratio of the colloidal portion that can be stably dispersed in the aqueous dispersion without settling, and shows the practical ability of dispersibility and stability. Further, the average particle diameter is a particle diameter of 50% of the cumulative volume measured by the laser method, and the ratio of particles having a particle size of 10 μm or more indicates the ratio (%) in the volume distribution. These measuring methods will be described in detail in Examples.

[0011] Also, the goodness of throat is related to the viscosity of the dispersion, and the lower the viscosity is, the better the texture of throat is. The water-dispersible composition of the present invention, fine cellulose,
Since it is composed of a hydrophilic substance that hardly causes viscosity, it is characterized in that it has a lower viscosity and better throat than Japanese Patent Application No. 4-259396. When the aqueous dispersion composition of the present invention is dispersed at a concentration of 2%, the viscosity is 200 centipoise (hereinafter referred to as cP
It is preferable that it is the following. Particularly preferably 5
It is 0 cP or less.

The water-dispersible composition of the present invention can be obtained by mixing and dispersing a finely divided cellulose dispersion and a hydrophilic substance to form a homogeneous slurry, and drying the slurry. The fine cellulose used in the present invention is required to have a proportion of particles of 10 μm or more of 40% or less and a colloid fraction of 50% or more. The average particle size at this time is about 8 μm
It is the following.

This fine cellulose dispersion is a wood pulp,
Cellulosic materials such as refined linters are depolymerized by acid hydrolysis, alkaline oxidative decomposition, enzymatic decomposition, steam explosion decomposition, etc. to give cellulose with an average degree of polymerization of 30 to 375, and then mechanically sheared and wet milled. Can be obtained by doing. Alternatively, the wet-milled product can be obtained by subjecting the colloidal portion to fractionation treatment by centrifugal sedimentation. Wet grinding machines suitable for the present invention include media mills such as wet vibration mills, wet planetary vibration mills,
Wet ball mill, wet roll mill, wet coball mill,
In addition to wet bead mills and wet paint shakers, there are high-pressure homogenizers and the like. As a high-pressure homogenizer, it is effective to use a high-pressure homogenizer having a high pressure of about 500 Kg / cm ² or more and introducing the slurry into a fine orifice to cause face-to-face collision at a high flow rate. The optimum milling concentration using these mills varies depending on the model, but a solid content concentration of 5 to 15% in the medium mill and 5 to 20% in the high pressure homogenizer is generally suitable.
A media mill is suitable for efficiently grinding cellulose. For the purpose of the present invention, these models can be used alone, or two or more models can be used in combination.

The water-dispersible composition of the present invention comprises fine cellulose having a colloid fraction of 50% or more and a hydrophilic substance. The purpose of compounding the hydrophilic substance is to prevent the finely divided cellulose particles from firmly binding to each other due to the formation of hydrogen bonds during drying, that is, returning the composition to the original colloidal dispersion when the composition is stirred in water. This is because. The hydrophilic substance referred to here is an organic substance having a solid hydroxyl group in the molecular structure at 25 ° C, which has high solubility in cold water and hardly causes viscosity, and is a starch hydrolyzate, dextrins, pregelatinized starch, glucose. , Fructose, xylose, sucrose,
Lactose, maltose, isomerized sugar, coupling sugar, palatinose, neo sugar, mannitol, reduced starch saccharified candy, maltose, lactulose, polydextrose,
Suitable are monosaccharides such as fructooligosaccharides and galactooligosaccharides, water-soluble sugars containing oligosaccharides, sugar alcohols such as xylitol, maltitol, mannitol and sorbitol, sorbose and the like.

The hydrophilic substance promotes the dispersion of the fine cellulose in the water when the composition is dispersed in the water, and maintains the colloidal fraction of the fine cellulose before drying by rapidly dissolving itself in the water. , The composition exhibits functions such as dispersion stability. In order to disperse the water-dispersible composition in water, it is necessary that the hydrophilic substance is 5 to 50% by weight with respect to 50 to 95% by weight of fine cellulose. When the content of the hydrophilic substance is less than 5% by weight, it is difficult to prevent strong bonding due to hydrogen bond between the fine cellulose particles in the drying step, and therefore the composition is not redispersed in water.
On the other hand, if it exceeds 50% by weight, redispersion of the composition occurs, but the performance as a stabilizer decreases as the fine cellulose content decreases, which is not preferable. Particularly preferably, the hydrophilic substance is 10 to 50% by weight with respect to 50 to 90% by weight of fine cellulose.

Regarding the components other than the fine cellulose and the hydrophilic substance, the components can be freely mixed to the extent that they do not hinder the dispersion of the composition in water. The composition of the present invention is obtained by first subjecting cellulose obtained by depolymerization treatment to fine cellulose by grinding it with a wet medium mill or a high pressure homogenizer so that the colloid fraction is 50% or more.
It is obtained by mixing this with a hydrophilic substance to form a slurry and then drying it. Also, after mixing a hydrophilic substance to the cellulose obtained by depolymerization treatment, this is subjected to a grinding treatment to form a slurry of fine cellulose and hydrophilic substance,
It is then obtained by drying it. In either case,
It should be noted that the hydrophilic substance is sufficiently dissolved and mixed uniformly. For this purpose, it is necessary to sufficiently stir and mix the hydrophilic substances in the presence of 75% or more of the total weight of water.

Drying is a major factor in the performance of water-dispersible compositions. It is preferable that the composition has a large number of network-like fine cracks formed therein upon drying.
The cracks become water-conducting pores, which promotes dissolution of the hydrophilic substance and dispersion of fine cellulose. This crack is a gap of about 0.05 to 0.5 μm, and it is preferable to suppress the distance between the pores to about 3 μm at the maximum.
It is dried in blocks using a band dryer or a rotary dryer described in JP-B-56-31094 and JP-B-57-14771, and this is dried, for example, in JP-A-4-108347.
In a method of crushing with an impact crusher such as SAMPLE-MILL described in Example 1 of Example 1, the structure having the cracks cannot be formed, and the composition is re-formed into the original fine cellulose particles in water. It cannot be dispersed.
As a drying method for giving this structure, freeze drying, spray drying or the like can be adopted, but it is preferable to dry in a film form. The freeze-drying method has poor production efficiency, and the spray-drying method has a drawback in that a large apparatus is required, quality control of the product is difficult, and redispersion performance of the dried product is easily varied. In the case of using a spray dryer, in order to reduce this variation, it is necessary to keep the spray particle size small and make the drying speed as fast as possible.

The method of drying in the form of a film is excellent as a method having the best dispersibility of the dry composition. The method of drying in the form of a film is a method of casting a uniform mixed slurry of fine cellulose and a hydrophilic substance on a substrate such as glass, stainless steel, aluminum or nickel-chromium plated steel plate and drying. The substrate may be preheated, or after casting, infrared,
You may heat with a hot air, a high frequency, etc. Drying temperature is 200
C. or less, and the thickness of casting is preferably 10 mm or less as the thickness of slurry. The slurry concentration is not particularly limited as long as it can be spread in the form of a film, but practically a solid content concentration range of about 5% to 20% is easy to work and a good dried product can be obtained. Further, industrially, a dryer such as a steel belt dryer, a drum dryer or a disk dryer can be adopted. Products dried in this film form are so-called film-like products, foil-like products,
It includes flakes, scales, filaments, and powders.

The dried product obtained by this film-like drying method can be directly used as a product. However, although a bulky film may be pulverized depending on the composition of the composition, the slurry concentration, the drying method, etc., pulverization and gentle pulverization such as sizing are preferable. Although impact mills such as hammer mills, pin mills and jet mills can be used, they tend to deteriorate the redispersion performance. Therefore, a preferable type is a cutter type having a relatively low rotational speed. Further, if the water content is too high, there is a problem of poor handling property, stickiness, and rot, and further, the redispersion performance is deteriorated due to the share in the drying, crushing, and sizing steps, so the water content is preferably 20% or less, Is 15% or less.

The water-dispersible composition obtained as described above is a dry product containing 2 to 20% of water, redispersed in water, and the proportion of particles of 10 μm or more is 40% or less, The colloid fraction has a performance of 50% or more, and forms a stable colloid dispersion having a smooth structure in which cellulose is uniformly dispersed and having no roughness. At this time, the average particle size of the dispersion is about 8 μm or less.

As the method for redispersing the composition of the present invention in water, various kinds of dispersing, emulsifying and grinding machines which are usually used in the food manufacturing process can be used. Typical examples include propeller stirrers, high-speed mixers, homomixers, various mixers such as cutters, ball mills, colloid mills, bead mills, mills such as liquor machines, high-pressure homogenizers, and ultrahigh-pressure homogenizers such as microfluidizers and nanomizers. A kneader, a grinder, etc. represented by a dispersing, emulsifying machine, a planetary mixer, a kneader, an extruder, a turbulator, etc. can be used. However, in order to obtain a suitable redispersion particle size, it takes a long time with a mixer having a low shearing force, and therefore it is practically preferable to use a disperser having a shearing force higher than that of a high speed mixer.

Compared with the composite obtained by blending water-soluble gums with the fine cellulose described in Japanese Patent Application No. 4-259396, 50-95% by weight of the fine cellulose of the present application and 5-50 parts by weight of the hydrophilic substance. The composition (1) has a low viscosity of the dispersion when redispersed in water, has good throat sensation, is free from roughness, and has good stability. Therefore, it should function as a stabilizer, etc., in applications that require uniform dispersibility and long-term stability, such as a suspension stabilizer, emulsion stabilizer, thickening stabilizer, and cloudy agent, which have a good texture.
