Abstract
The present invention provides a product containing glucomannan mixed with encapsulated acidic material having a wall made of hydrophobic substance which melts at a temperature higher than the coagulating temperature of the glucomannan. Because this acidic material is covered with a wall, when alkali is added to the mixture which is then heated, the glucomannan is coagulated. Then, the wall of the encapsulated material is melted by heating to liberate acid, neutralizing the alkaline substance, and producing a slightly alkaline, neutral or acidic glucomannan coagulated product. Further, although the glucomannan coagulated product has a water- releasing property, this can be reduced by adding other natural polysaccharides. Also, a decrease of elasticity caused by neutralization can be eliminated by adding food cellulose.
