Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a fluid granular material containing an oil-soluble substance.

Conventionally, methods for producing powders or granules containing oil-soluble substances include adding oil-soluble substances to excipients such as dextrin, starch, and glucose, and forming them into granules by crushing granulation, spray drying granulation, etc. A method of directly adsorbing an oil-soluble substance to dextrin or a glue: A method of making the glue porous and adsorbing an oil-soluble substance is known.

However, in the method of adding oil-soluble substances to excipients such as dextrin, starch, and glucose and making them into granules by crushing and granulation, the oil-soluble substances may volatilize due to generated heat, etc.
There are drawbacks such as oxidation, and the method of forming granules by spray drying granulation requires high production costs even though the heat applied to the oil-soluble substance is not so great.

In addition, in the method of directly adsorbing oil-soluble substances to dextrin or starch, the adsorbed powder has very poor fluidity and may stick to the vessel wall during secondary processing, making it difficult to measure. This makes it difficult to automate the manufacturing process and save labor.

Furthermore, in the method of adsorbing oil-soluble substances onto porous starch, starch is generally made porous by heating it under pressure and then rapidly lowering the pressure. In reality, this method has not been put to practical use because its original properties have changed and its uses during secondary processing have been limited, and the oil absorption has not been significantly improved.

In addition, as a method for granulating spices, a method is known in which spice oil is adsorbed onto a granulated edible carrier, but in this method, due to the heat generated during the granulation or drying process, This method is hardly used in Japan because the raw material for granulation is denatured by heating or the oil absorption of the granulated product is poor.

Under these circumstances, there has been a desire for a granular material that can occlude a large amount of an oil-soluble substance without impairing the quality of the oil-soluble substance, has fluidity, and can be used in many ways.

Therefore, the present inventor conducted various research in order to obtain a substance that has fluidity even when it absorbs a large amount of oil-soluble substances and can be used in many ways. After adding water to starch or grain flour and granulating it, When oil-soluble substances are occluded in the heat-dried material by irradiation with ~55 μ long wavelength infrared rays, a large amount of oil-soluble substances are occluded, and the granular substances that occlude these oil-soluble substances have good fluidity. They discovered this and completed the present invention.

That is, the present invention provides: (1) starch and/or grain flour; (2) a mixture of starch and/or grain flour and a food leavening agent; (2) a mixture of starch and/or grain flour and a thickening agent; (2) a mixture of starch and/or grain flour and a food leavening agent and a thickening agent. After adding water to a raw material selected from the group consisting of a mixture of
A method for producing a fluid granular material containing an oil-soluble substance, which comprises occluding an oil-soluble substance in a granular substance mainly composed of starch obtained by heating and drying by irradiating with long-wavelength infrared rays of ~55μ. The purpose of this is to create fluid granules containing oil-soluble substances that occlude a large amount of oil-soluble substances and have physical properties suitable for the production of foods, drugs, cosmetics, detergents, etc. The object of the present invention is to provide a method for manufacturing a substance like this at low cost and in large quantities.

The present invention will be explained in detail below.

Examples of the starch used in the present invention include wheat starch, potato starch, corn starch, waxy corn starch,
Starches such as rice starch, tapioca starch, sweet potato starch, and arrowroot starch are mentioned, and these may be unmodified products, modified products, derivatives, or crosslinked products, and one or more of these may be selected as appropriate. It can be used as

Examples of the grain flour include wheat flour, rice flour such as glutinous rice flour, glutinous rice flour, turgium flour, corn flour, buckwheat flour, rye flour, and the like, and one or more of these can be selected and used as appropriate. can.

These starch and flour may be used alone or in a suitable mixture.

In addition, if the raw material is starch and/or grain flour with a food leavening agent added, it is possible to improve the drying efficiency of granular materials mainly composed of starch and improve oil absorption.
Preferably, a food leavening agent is added to the starch and/or flour.

Examples of the food leavening agent include ammonium chloride, d
-1dl -Potassium hydrogen tartrate, ammonium carbonate, potassium carbonate, ammonium hydrogen carbonate, sodium hydrogen carbonate, ammonia-based synthetic expansion agents, etc. may be used, and these can be selected and used as appropriate, but they decompose and volatilize when heated. is desirable.

The amount of the food leavening agent added is preferably 5% or less based on the starch and/or grain flour.

Furthermore, since it is undesirable to apply more heat and pressure than necessary when granulating a hydrated product obtained by adding water to starch and/or grain flour, a sizing agent may be added to the starch and/or grain flour as necessary. It is preferable to granulate it.

Examples of the sizing agent include sodium alginate, propylene glycol alginate, casein, sodium caseinate, calcium cellulose glycolate, sodium cellulose glycolate, sodium starch glycolate, sodium temprate, methylcellulose, and sodium polyacrylate. These can be appropriately selected and used.

These thickeners may be added to starch and/or flour alone, or may be added in combination with a food leavening agent.

Next, water is added to the raw material or raw material mixture as described above, and the resulting hydrate is granulated.

At this time, if the amount of water added is too small, granulation will not be possible, and if the amount of water added is too large, it will become dense granular material and the drying efficiency will be poor. It is preferable to add water so that the moisture content is in the range of 15 to 50%.

Although it is desirable to add water by spraying, a normal method for adding water may be used.

Any granulation method can be used as long as it can be granulated using heat and pressure that does not change the original properties of starch and flour, such as screw type, roll type, flade type, and ram type. Examples include extrusion granulation methods using molds, self-molding molds, etc.; wet crushing granulation methods using screen separation or screenless methods; transfer granulation methods using drum or dish molds; and other agitation granulation methods. These can be appropriately selected depending on the type of raw material and the particle size or shape of the granular material.

When heating or pressurizing is required in these granulation methods, care must be taken to maintain the temperature of the granulated product so as not to change the original properties of the starch and flour.

For example, if the raw material is normal starch or grain flour, it is preferable to set the heat and pressure conditions so that the product temperature does not exceed 70°C, but if the main ingredient is alpha starch, the temperature of the granulated product is Temperatures above 70°C are acceptable.

In addition, the granular material mainly composed of starch in the present invention refers to 3.
It is a combination of powder and granules of 0 to 700μ, but the particle size or shape is determined by selecting the appropriate granulator depending on the application during secondary processing, and adjusting the screen, pores, and rotation of each granulator. number,
A desired result can be obtained by adjusting the granulation time and the like.

Next, the above-mentioned granules are heated and dried by irradiating them with long wavelength infrared rays of 3 to 55 microns.

As a device that generates long wavelength infrared rays of 3 to 5511,
It is possible to use a device that uses a solid material such as tungsten, nichrome wire, silicon carbide, or ceramic as a heating element and emits mainly long-wavelength infrared rays of 3 to 55 microns.

The wavelength characteristics of long-wavelength infrared rays are determined by the type of heating element or its surface temperature, and it generally has a mountain-shaped wavelength distribution. Long-wavelength infrared rays with such wavelength characteristics are effectively used, but special nichrome An infrared drying device that emits intense long-wavelength infrared rays over a range of 3 to 55 microns with a surface temperature in the range of 400 to 12,000 degrees Celsius is desirable.

Furthermore, the heating temperature for granules mainly composed of starch,
Temperature rise, irradiation time, irradiance, etc. may be adjusted as appropriate depending on the moisture content before drying of the granular material mainly composed of starch, particle size, finishing conditions, etc., but the irradiation distance is 80~
The range is preferably about 400 mm.

In addition, during the drying process, in order to improve drying efficiency, it is possible to use two or more infrared drying devices with different irradiances in series. For example, when adding a swelling agent, the irradiance is first If the expanding agent is volatilized by strong and short-time long-wavelength infrared rays, a good granular material mainly composed of starch can be obtained.

Furthermore, during the drying process, the drying efficiency can be further improved by rolling the granules.

In this way, when long-wavelength infrared rays of 3 to 55 μm are irradiated to granules mainly composed of starch, the long-wavelength infrared rays heat the granules mainly composed of starch in the form of electromagnetic waves without placing any transmission medium in between. is immediately converted into thermal energy, and water strongly absorbs especially long-wavelength infrared rays of 3 μ, 6 μ, and 12.5 to 19 μ, so it does not change the original properties of starch and flour and generates char. It can be heated and dried extremely efficiently without any problems, and can also be sterilized.

Next, an oil-soluble substance is occluded into the granular material mainly composed of starch obtained by heating and drying as described above.

Examples of the oil-soluble substances include lard, lanolin, squalane, sesame oil, mustard oil, lemon oil, orange oil,
Animal and vegetable oils and fats such as paprika oleoresin and olive oil; Emulsification stabilizers and emulsifiers such as soybean lecithin, glycerin fatty acid ester, sucrose fatty acid ester, sorbitan fatty acid ester, propylene glycol fatty acid ester; Spice flavor, meat flavor, strawberry flavor, melon flavor, strawberry Flavor Oil-soluble flavors such as vanilla flavor; Food flavoring agents such as menthol, linalool, fatty acids, and esters; Higher alcohols such as oleyl alcohol; Fatty acid esters such as isopropyl myristate; Higher alcohol esters such as methacrylic acid urirate; lactic acid , gluconic acid, butyric acid, and other organic acids; and 1 selected from these.
One species or two or more species can be used depending on the purpose of the secondary processed product.

When these oil-soluble substances are occluded in granular substances mainly composed of starch, they may be occluded directly, or they may be occluded after being dissolved in a solvent such as alcohol, acetone, glycerin, propylene glycol, or the like.

Any method may be used as long as it can uniformly occlude oil-soluble substances into granular materials mainly composed of starch, such as using a ribbon mixer, continuous jet mixer, etc. It can be occluded.

Granular substances mainly composed of starch can occlude the same or double the amount of oil-soluble substances, but in order to maintain good fluidity, 20 to 40% of the granular substances mainly composed of starch should be occluded. is preferable.

The fluid granular material containing an oil-soluble substance obtained by the method of the present invention is a granular material that occludes a large amount of an oil-soluble substance without being heated except for the purpose of melting the oil-soluble substance. Since it has excellent physical properties such as fluidity, it is very convenient to handle and can be manufactured with stable quality in the production of foods, medicines, cosmetics, detergents, etc.
