JPH06277159A - Dried product of konjak sponge and manufacture thereof - Google Patents

Abstract

PURPOSE:To improve a commodity value of konjak sponge for washing one's face and babies by drying a sponge made of konjak and mixed with a plasticizer before the drying and reducing a contraction property and deformability of the sponge. CONSTITUTION:50 grams of konjak powder is dissolved in 2.4 Ls of water. Separately 72 grams of carageenan is dissolved in 2.4 L of water, cooled and gelatinized to be cut to a cube having a certain dimension. Next, the carageenan gel cube and lime water are added to the konjak power solution and poured into a mold to be molded and gelatinized. Further, the carageenan gel cube in the obtained gel molding is dissolved and removed with hot water. The gel molding free from the carageenan gel cube is freezed, then thawed and dehydrated to make a konjak sponge. Thus, goods having small contraction and deformation by drying, rich in the flexibility, easy to transport and used for cleaning one's face and babies are manufactured.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dried product of konjak sponge having a high commercial value and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, konjak sponges have been obtained by freezing konjak containing glucomannan, which is a natural polysaccharide, as its main component. It is often used for face washing and washing of infants.

Since the above-mentioned konjak sponge is a natural polysaccharide, if it is left in the environment while containing water,
As mold and bacteria propagate and deteriorate due to it, they are transported and sold in a dry state. However, when hot air drying, which is a general drying method, is applied, there is a problem that the dried product shrinks and deforms, which lowers the product value. As a countermeasure, there is a method of performing freeze-drying, but there is another problem that the equipment cost and running cost are high, and it is not suitable for manufacturing on an industrial scale.

[0004]

The problem to be solved is that the above-mentioned conventional hot air drying uses large shrinkage / deformation and has low product value, and the freeze-drying uses equipment. The cost and running cost are high, and it is not suitable for manufacturing on an industrial scale.

[0005]

The first invention is a dried product of konjak sponge containing a plasticizer.

The second invention is a method for producing a dried konjak sponge product, which comprises impregnating a konjak sponge with a plasticizer prior to drying the konjak sponge.

[0007]

EXAMPLE A method for producing konjak sponge will be described. First, 50 g of konjak powder is dissolved in 2.4 liters of water. Separately 72 grams of carrageenan 2.4
Dissolve in 1 liter, cool to gel, and cut the resulting gel into cubes of constant size to make carrageenan gel cubes. Next, a carrageenan gel cube and lime water are added to the konjac flour solution, and the mixture is poured into a mold to be molded and then gelled. Further, the carrageenan gel cube in the obtained gel molded product is dissolved and removed in hot water. After removing the carrageenan gel cubes, the konjak sponge is obtained by thawing and dehydrating after freezing.

This konjak sponge is immersed in a plasticizer, for example, a 20% by weight glycerin solution, dehydrated, and then dried at 75 ° C.
When dried for 1 hour, the obtained konjak sponge dried product had a shrinkage rate of 18% based on the size standard before immersion in the glycerin solution, showed no deformation, and was highly flexible. The glycerin content of the dried product was about 50%. As the plasticizer, a polyhydric alcohol having a moisture-retaining property can be used, but in consideration of completeness, propylene glycol, polyethylene glycol and the like are suitable in addition to glycerin.

Further, the same konjak sponge was dipped in a 60 wt% glycerin solution, dehydrated and dried at 95 ° C. for 1 hour. 20%
However, no deformation was observed and it was rich in flexibility. The glycerin content of the dried product was about 75%.

When the same konjak sponge was not immersed in the glycerin solution and dried at 75 ° C. and 95 ° C. for 1 hour, the obtained konjak sponge had a shrinkage rate of 25% and was hard. It was transformed.

To explain the operation, the dried konjak sponge containing a plasticizer has little shrinkage / deformation due to drying, is highly flexible, is less likely to be damaged during transportation, and has a shape when immersed in water. It is quickly restored and has high commercial value.

[0012]

Since the present invention is constructed as described above,
The obtained dried product was smaller than the conventional blow-dried product in terms of both shrinkage rate and deformation degree, and the commercial value was significantly improved. When the dried product of the present invention was immersed in water, it returned to the state before drying and no change in physical properties was observed.
