The present invention is a process for creating a konjac glucomannan based food product. More specifically, the method for transforming konjac glucomannan solutions into heat-stable gels requires the use of heat and a high pH to deacetylate the konjac glucomannan molecule. A minimum concentration of 1.5-2% konjac glucomannan is necessary to adjust the system to a pH of approximately 9.0. When the solution is heated to 85° C. with a mild alkali condition (pH 9-10) it forms a gel which is unaffected by heat. Thus, the gel remains stable when additional heat is applied and remains unchanged under repeated heating at 100° C. or even at 200° C. Alternatively, the addition of an alkali, like Ca(OH)₂ in a konjac glucomannan solution removes its acetyl group forming a stable network structure to form the gel structure. By mixing the konjac glucomannan soluble fiber, with any kind of insoluble fibers and alkalis together, a pure fiber konjac gel food can be made by simply pouring the complex powder into water applying heat. The traditional konjac gel foods texture is hard, chewy and rubbery, the new gel foods in which the insoluble fiber is added improves the texture of the gel foods.

The texture of a starchy food (for example, biscuits, cookies, cakes, breads, cream puffs, coated and fried foods, snack foods, wheat noodles, Chinese noodles, etc.) is highly improved by using soybean protein in a smaller amount than in the conventional methods. The effect of improving the food texture somewhat varies depending on the water activity of a food. In the case of a food having a high to moderate water content, it is intended to achieve a soft texture, a favorable feeling on the tongue and a high meltability in the mouth. In the case of a food having a low water activity such as baked goods or toast, on the other hand, it is intended to achieve a crispy and light texture. In the case of wheat noodles and Chinese noodles, it is intended to achieve a flexible texture with an adequate elasticity. By using soybean protein in a smaller amount than in the conventional methods, it is intended to sufficiently relieve troubles (loss in the product volume and worsening in appearance) and poor handling properties (lowering in workability) accompanying the use thereof in a large amount. A starchy food material or a starchy food is obtained by adding acid-soluble soybean protein to a starch material such as wheat flour or starch. The acid-soluble soybean protein can be used in an amount of from 0.05 to 7% by weight based on the starchy material.
