Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to brown sugar-containing powder and a method for producing the same. More specifically, the present invention relates to brown sugar-containing powder obtained by dissolving brown sugar and indigestible dextrin and spray-drying the powder, and a method for producing the powder. The brown sugar referred to here is a molasses sugar made by boiling sugar cane juice.

[0002]

BACKGROUND OF THE INVENTION Brown sugar, also called brown sugar, is obtained by neutralizing sugar cane juice, heating and concentrating it to solidify it into bricks or crushed powder, which is derived from sugar cane. It is a food that contains all the nutrients that are not made. It contains a lot of minerals, but it is said that it has a lot of potassium and also has a blood pressure lowering effect. It is thought that Okinawa has many long-lived people because it has been using brown sugar for a long time, and it has become a hot topic as a health food these days. Further, it has a unique taste and aroma and is deeply tasted, and is widely used industrially as a raw material for foods such as Japanese sweets, Western sweets and bread.

However, most of the brown sugars used at present are solid and coarse-grained ones, and the coarse-grained ones tend to solidify to form large lumps. Even when such brown sugar is dissolved in water and used, it is inconvenient to measure and it takes time to dissolve. Difficult to mix,
Limited use. In addition, sometimes a large amount of foreign matter is often a problem. Therefore, there is a demand for a uniform brown sugar powder that eliminates these drawbacks.

To uniformly powder brown sugar, the spray drying method is effective because the particle size can be adjusted to some extent and the other raw materials can be easily mixed. However, when brown sugar is once dissolved and normally spray-dried, the powder obtained is non-crystalline and very likely to absorb moisture, and solidification occurs in the spray dryer main body and cyclone. Also, at high temperatures, brown sugar is in a state where it does not release water and cannot be pulverized.

Therefore, even if a powder carrier such as dextrin or lactose is mixed and spray-dried when dissolving brown sugar as a conventional means, the above-mentioned drawbacks are still exposed when the content of brown sugar is high. The more powder carriers are used, the more their drawbacks are ameliorated, but the content of brown sugar is relatively small and the value of the product is lost.

[0006]

DISCLOSURE OF THE INVENTION The present invention makes it easy to handle brown sugar, which is difficult to spray-dry as described above, and makes it an economical spray-dried powder that has few foreign substances and is easy to handle. The purpose is to enable easy addition and mixing.

[0007]

Means for Solving the Problems As a result of earnest studies on a powdering method by spray-drying brown sugar, the inventors of the present invention described above by mixing and dissolving indigestible dextrin in brown sugar, and then forming the powder by spray-drying method. It was found that the above problem can be solved, and in addition, the function as dietary fiber such as intestinal regulating action of indigestible dextrin can be added, and the present invention was completed.

That is, the present invention is a brown sugar-containing powder obtained by mixing and dissolving indigestible dextrin in brown sugar, and powderizing the mixture by spray drying, and a method for producing the same.

The brown sugar of the present invention is obtained by neutralizing sugar cane juice and then heating and concentrating it, and is not particularly limited to a production method, a production area, or the like, and may be a mixture of a plurality of types of brown sugar.

The indigestible dextrin of the present invention means that the enzyme acts on the roasted dextrin made from cornstarch, and glucose is α-1,4 bond, and α-1,3 bond, and α-1,6. A dextrin in the form of a polymer formed by binding is prepared, further purified by an ion exchange resin or the like, and powdered.

In addition to brown sugar and indigestible dextrin,
Other powder carriers may be added. Examples of the powder carrier include commonly used dextrin, starch syrup, starch, modified starch, lactose, sugar, glucose, fructose, maltose, vegetable protein, animal protein, and cellulose, but are not particularly limited. In addition, vitamins, minerals and the like may be added for the purpose of nutritional enhancement, and Na glutamate, 5'-mononucleotide, organic acid, salt and the like may be added as seasonings.

In the present invention, in the step of dissolving and dissolving indigestible dextrin in brown sugar, the blending ratio of brown sugar is 50% or more and 85% or less, preferably 65% or more 75% in terms of solid content.
% Or less is desirable. Below the lower limit, the content of brown sugar is small and the commercial value is low, so the present invention is meaningless. Above the upper limit, it becomes difficult for brown sugar to separate water, and good powder cannot be obtained by spray drying.

The proportion of the indigestible dextrin in terms of solid content is 5% or more and 50% or less, preferably 8% or more and 35%.
The following is desirable. Below the lower limit, the effect of indigestible dextrin does not appear, and above the upper limit, the proportion of brown sugar is relatively decreased and the commercial value is diminished.

As the conditions for spray-drying the brown sugar-containing solution obtained by the above method, a hot air inlet temperature of 100 to 160 ° C. and an exhaust air temperature of 70 to 100 ° C. are desirable in order to obtain a good powder. If the hot air inlet temperature exceeds 160 ° C, brown sugar is difficult to separate water and good powder cannot be obtained. Further, the spraying method may be any of a high pressure nozzle, a two-fluid nozzle, a pressurized two-fluid nozzle, or a disc method.

The brown sugar-containing powder of the present invention is obtained by a smooth drop from the spray dryer main body and a smooth recovery from the cyclone without solidification. If it is hermetically sealed, solidification due to moisture absorption or natural solidification does not occur, and the powder is good and easy to handle.

Moreover, even if the brown sugar-containing powder obtained according to the present invention and wheat flour are premixed and sealed in a plastic bag or a kraft bag, no solidification or the like occurs. Can be used without any problems.

(Comparative Example 2) The same procedure as in Example 1 was carried out except that 3.5 kg of brown sugar produced in Thailand and 1.5 kg of dextrin (Matsutani Chemical Co., Ltd., trade name Paindex # 3) were dissolved in 5 kg of hot water at 50 ° C. Spray dried. As a result, there was a lot of adhesion from the spray dryer itself but it also dropped, and 2 kg of brown sugar-containing powder was obtained, but rock-like solidification occurred in the cyclone, and recovery from the cyclone became impossible, and spray drying continued. It became impossible.
