Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sweetener containing an oligosaccharide which has improved hygroscopicity and fluidity and is hard to be solidified, and a method for producing the same.

[0002]

2. Description of the Related Art Powdery or granular products of oligosaccharides are easily solidified, and an airtight aluminum bag or a desiccant is used for storage.

However, even if it is hermetically sealed and a desiccant is used, if it is kept at a high temperature in summer for a long time, it tends to be solidified by a trace amount of water held by the oligosaccharide itself.
If dextrin, starch or the like is added to prevent caking, the sweetness of the oligosaccharide will be reduced accordingly. Again sugar,
It is not preferable to add a sweetener such as glucose because the portion that comes into contact with the oligosaccharide will start to solidify and the whole will solidify.

SUMMARY OF THE INVENTION An object of the present invention is to provide a sweetener which can solve the problem of solidification due to hygroscopicity of oligosaccharides and a method for producing the same.

A further object of the present invention is to provide a sweetener containing an oligosaccharide having excellent fluidity and sweetness, and a method for producing the same.

Means and Actions for Solving the Problems As a result of intensive studies for solving the above problems, the present inventors have found that α-L-aspartyl-L-phenylalanine methyl ester (hereinafter referred to as aspartame) at room temperature. Focusing on its low solubility in water and the difficulty of binding aspartame particles to each other, we have succeeded in developing a sweetener that enhances sweetness and prevents caking.

The present inventors have proposed a method of attaching aspartame to powdery or granular oligosaccharides by attaching aspartame, as a method of preventing solidification while maintaining sufficient sweetness without decreasing the physiological functionality of the oligosaccharides. We have developed a method for forming oligosaccharide particles that have moisture resistance and fluidity and have a high degree of sweetness by forming a film of aspartame on the surface of which is difficult to harden.

That is, the present invention provides a method for producing a sweetener, which comprises spraying a solution of aspartame dissolved or slurried in water or alcohol on powdered or granular oligosaccharides, adhering and drying, and The present invention relates to a sweetener which contains oligosaccharides having aspartame impregnated or coated thereon, and the amount of aspartame with respect to the oligosaccharides is not more than an equal amount.

The present invention will be described in more detail below.

The oligosaccharide in powder or granular form used in the present invention may be any oligosaccharide as long as it can be used for ordinary food and drink. Examples thereof include lactulose, fructooligosaccharides, galactooligosaccharides, raffinoses, isomaltooligosaccharides, xylooligosaccharides, lactosucrose, palatinose oligosaccharides, and gentio-oligosaccharides. In particular, the improvement of the fluidity and hygroscopicity is remarkable.

The particle size of the oligosaccharide used as a raw material is not particularly limited, but it is usually preferable to use one having a size of about 5 mesh to 200 mesh, more preferably 20 mesh to 60 mesh. Further, the finer the particle size of aspartame used as a raw material in the present invention, the better, but 100 mesh pass is preferable. The amount of aspartame with respect to the oligosaccharide may be equal to or less than that, but is preferably about 0.1% to 1%. That is, the object of the present invention can be sufficiently achieved by using a small amount of aspartame.

The concentration of the aspartame solution dissolved or slurried in water or alcohol may be 0.5% to 5% with respect to water or alcohol, but preferably 1.
It is in the range of 5% to 3.5%, and the temperature of the solution is 60 ° C to 8%.
0 ° C is preferred.

The alcohol used is preferably ethyl alcohol, and more preferably a 10% to 25% ethyl alcohol aqueous solution. When preparing these aspartame solutions, in addition to aspartame, α-starch, dextrin, lactose and a natural or synthetic paste may be added in an appropriate amount, for example, about 1 to 2% based on oligosaccharide. Among them, it is preferable to add dextrin.

In the present invention, the spraying and drying of the aspartame solution on the oligosaccharide is carried out, for example, by placing the oligosaccharide powder in a fluidized bed granulation drier and blowing hot air from the bottom of the drier to make the oligosaccharide powder flow. This can be done by spraying and drying the aspartame solution.

The atomizing air pressure is ² Kg / cm ^{2 to 5} Kg / c
The range of m ² is preferable, and it is preferable to use a metering pump for the spray liquid. In addition, the flow condition of oligosaccharides may be adjusted by adjusting the blower and exhaust tumblers so that the flow condition may be kept smooth, and if the spray liquid feed rate becomes excessive, the flow state may deteriorate. Is preferably dropped or stopped and the surface of the oligosaccharide is dried. In addition, it is preferable to spray hot water on the oligosaccharides having aspartame attached thereto before drying, to perform surface treatment of the particles.

The drying conditions are preferably such that the exhaust temperature is in the range of 50 ° C to 60 ° C. Blower temperature is 80
It is preferable to control the temperature between 0 ° C and 100 ° C.
