Description

Detailed Description of the Invention <Field of Industrial Application> The present invention provides a powdered sugar with improved hygroscopicity that can be added as an additive in the fields of foods such as confectionery and bread making, and feed. This relates to a manufacturing method.

<Prior art and its problems> It is known that sugars generally undergo phenomena such as assimilation and deliquescence due to moisture absorption, and powdered sugar, which is obtained by crushing granulated sugar and has a small particle size and a large surface area, is the most obvious example, and these phenomena reduce the value of sugars and products that use sugars. In addition, it is desirable for sugars used as sweeteners to maintain a sweet taste in the mouth for a long time, and when using sugars dispersed in fats and oils, such as in oil-based suspensions, sugars that are easily compatible with fats and oils are required. . Research has been carried out in the past to solve the above problems. For example, as a method of adding cyclodextrin to sugars, there is a method for preventing deliquescence of organic deliquescent substances (Japanese Patent Publication No. 58-44349), r powder. "Method for Preventing Sugar Caking" (Special Publication No. 61-4447), etc.
Examples of the method for adding maltose include "Method for Preventing Sugar Caking" (Japanese Patent Publication No. 56-46760), and other methods include adding dextrin and starch. However, the reality is that none of these methods has an excellent effect of preventing deliquescence and the like.

Furthermore, conventional methods of coating the core material with lipids, etc. require the addition of a large amount of coating agent, which increases costs. This has the disadvantage that a large amount of energy must be consumed and the work, including the maintenance of the equipment, becomes complicated.

Furthermore, powdered saccharides with improved hygroscopicity whose core substance is saccharide powder have not been known at all.

<Objective of the Invention> Therefore, an object of the present invention is to provide a powdered sugar with significantly improved coating performance and improved hygroscopicity, and a method for producing the same.

Another object of the present invention is to provide a powdered sugar that can prevent assimilation and deliquescence due to moisture absorption, and a method for producing the same.

Yet another object of the present invention is to provide a process for producing powdered sugars in which there is no need to dissolve the coating agent, thus avoiding large consumption of energy and in which the equipment used is easy to maintain.

Still another object of the present invention is to provide a powdered saccharide that has a high content of saccharide powder as a core substance, so that a sufficient effect as 1M can be obtained by using a small amount of coated preparation, and therefore the cost can be reduced. and its manufacturing method.

Means for Solving Problems〉 According to the present invention, sugar powder as a core substance and melting point 4
A coated powdered saccharide comprising a lipid powder having a temperature of 0°C or higher,
A powder with improved hygroscopicity, which is obtained by contacting and colliding the lipid powder as a coating agent with the sugar powder as a core material, and adhering and coating the surface of the sugar powder with the lipid powder. Sugars are provided.

Further, according to the present invention, a lipid powder having a melting point of 40° C. or higher is brought into contact with and collided with a saccharide powder as a coating agent, and the surface of the saccharide powder is adhered and coated with the lipid powder. Provided is a method for producing powdered saccharide with improved hygroscopicity, which comprises producing coated saccharide coated with lipid using the saccharide powder as a core material.

In the following, the present invention will be explained in more detail.
Sugar powder is used as a core material, and lipid powder is attached to the surface.
A coated powdered sugar is prepared. Examples of the sugar powder that is the core substance of the coated powdered sugar include monosaccharides such as glucose, mannose, galactose, fructose, sorbose, tagalose, arabinose, xylose, ribose, ribulose, erythrose, and threose;
Trehalose, saccharose, maltose, cellobiose, gentiobiose, lactose, raffinose, gentiano-schemaltotriose.

Dextrin, starch, glycogen, obtained by decomposing oligosaccharides or polysaccharides such as manninotriose,
Inulin, lichenin, cellulose.

Polysaccharides such as chitin, hemicellulose, pectin, vegetable gums, and other natural or synthetic products can be used. Furthermore, it is also possible to use those obtained by subjecting these saccharides to treatments such as decomposition, oxidation, reduction, pregelatinization, esterification, etherification, crosslinking, and grafting. Moreover, two or more types of saccharide powders may be combined as necessary.

In the present invention, the lipid powder having a melting point of 40°C or higher that coats the surface of the core material includes animal and vegetable oils such as beef tallow, pork fat,
Mention may be made of hydrogenated or fractionated oils such as fish oil, soybean oil, rapeseed oil, palm oil, and others, for example fatty acid monoglycerides.

Fatty acid diglyceride, propylene glycol fatty acid ester, ci:l sugar fatty acid ester, fatty acid.

Select one or more of the following: higher alcohols, waxes, phospholipids containing phosphorus and nitrogen, glycolipids with sugar as constituent components, sulfolipids with sulfonic acid groups, sterols, hydrocarbons, and cured products thereof. be able to. If the melting point of the lipid powder is less than 40°C, there is a risk of melting at room temperature, making it impossible to obtain a good lipid powder.

For coating, sugar powder as a core substance and melting point 4
The lipid powder at a temperature of 0°C or higher is brought into contact with and collided with each other. Specifically, we use known mixers, ball mills, electric mortars, high-efficiency powder mixing devices, devices that mix and contact powders using high-speed air convection, and thereby bring the powders into contact with each other.
At the same time, the lipid powder is caused to contact and collide with the inner wall of the device and the auxiliary tools, so that the lipid powder adheres to the core material, the 1lII type powder.
Cover. If contact and collision are made under extreme conditions, there is a risk that the core material will be crushed and the contents will be scattered, so it is desirable to make contact under as mild conditions as possible, and when making contact with the above device, Coating performance can be improved by powder-mixing the saccharide powder and the lipid powder, which are core substances, in advance.

Furthermore, in the present invention, the sugar powder may be granulated or pre-coated with a water-soluble component, an oily substance, or the like before the sugar powder and lipid powder are mixed and brought into contact and collided with each other. Examples of the water-soluble components include sugars, proteins, amino acids, and inorganic salts. Examples of the oily substance include natural oils and fats, hydrogenated oils, waxes, fatty acid monoglycerides, fatty acid diglycerides, fatty acids, and other lipids. Further examples include natural or synthetic organic and inorganic polymers.

The granulation or pre-coating can be carried out by a known method. For example, there is a method called a fluidized bed method for pre-coating, in which the saccharide powder is fluidized by wind force or stirring blades, and then A method of coating by spraying a water-soluble component or an oily substance for pre-coating is preferred.

The particle size of the lipid powder used in the present invention is preferably 0.1 μm to 1 μm, and preferably the same or smaller than that of the saccharide powder that is the core material.

The mixing ratio of the coated saccharide powder and lipid powder (saccharide powder weight/lipid powder weight) can be used in the range of 0.1 to 1000, but the particle size ratio It is preferable to prepare according to the following relationship. When the particle size ratio is large, it is preferable to increase the mixing ratio, and when the particle size ratio is small, it is preferable to increase the mixing ratio.
It is desirable that the mixing ratio be 4 or less. Simply reducing the mixing ratio does not necessarily improve the coating performance; rather, a larger mixing ratio may actually provide better performance. Furthermore, even if the mixing ratio is the same, coating performance can be improved by dividing the lipid powder into two or more parts and coating them several times.

In any case, it is necessary that the coating agent coats and adheres to the surface of the core substance. If the coating agent is not coated and attached to the surface, the sugar powder that is the core substance inside will dissolve to the outside. This is because

<Effects of the Invention> The powdered sugar with improved hygroscopicity and the method for producing the same of the present invention can reduce contact between sugar and water,
Deliquescence during solidification due to moisture absorption of sugar-containing powder can be prevented. This makes it possible to withstand long-term storage compared to conventional powders, and products that use this powder can be prevented from "disappearing" due to deliquescence, thereby preventing a decline in quality. can. Furthermore, since it has become possible to suppress contact with moisture, when the coated saccharide of the present invention is placed in the mouth, a product with a long-lasting sweetness can be obtained.

Furthermore, when dispersing saccharides in an oily suspension, saccharides with good compatibility and good dispersibility can be obtained.

Furthermore, it is possible to reduce the amount of lipid powder itself added,
Therefore, it is possible to reduce the cost of using lipid powder, and the method for producing powdered sugars with improved hygroscopicity of the present invention is simpler in terms of energy and work compared to conventional production methods. is possible.

As described above, the method for preventing deliquescence of saccharides of the present invention has greater effects than conventional methods and is extremely useful.
