Abstract
Abstract A process for producing a konjak (a substance made from the starch of the corms of the plant Amophorphallus Rivievi) jelly which may be added to various kinds of food is disclosed. The konjak jelly is produced by adding water to konjak flour to cause the latter to swell and dissolve in the former, and mixing the resulting paste with a basic amino acid, a basic salt, or a mixture thereof; or adding to konjak flour water which has been mixed with a basic amino acid, a basic salt, or a mixture thereof in advance; or mixing konjak flour with a basic amino acid, a basic salt, or a mixture thereof in advance, and adding water to the resulting mixture to cause the latter to swell and dissolve in the former; and heating the resulting konjak paste under alkaline conditions and then cooling it. The konjak jelly thus produced may be added to various kinds of food to improve the flavor or the like or may be added to diet food. Thus, it is possible to diversify the use of konjak.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
137 words
A process for producing a thermally irreversible thickened gel which is blendable with other food products, said process comprising the steps of: (a) forming a konjak past by mixing components consisting essentially of konjak flour, an amount sufficient of water to cause the konjak flour to swell and dissolve, and a basic amino acid, a basic salt, or mixture thereof; (b) heating said konjak paste under weak alkaline conditions at a temperature and time sufficient to begin the setting of said konjak paste, said temperature being about 60° C. or more, to thereby begin setting of said konjak paste; and (c) then, prior to completion of setting of said heated konjak paste, rapidly cooling the heated paste and thus stopping said setting prior to essential completion of said setting of said konjak paste into a firm gel.
Claim 2
Dependent Claim
137 words
A process for producing a thermally irreversible thickened gel which is blendable with other food products, said process comprising the steps of: (a) forming a konjak past by mixing components consisting essentially of konjak flour, an amount sufficient of water to cause the konjak flour to swell and dissolve, and a basic amino acid, a basic salt, or mixture thereof; (b) heating said konjak paste under weak alkaline conditions at a temperature and time sufficient to begin the setting of said konjak paste, said temperature being about 60° C. or more, to thereby begin setting of said konjak paste; and (c) then, prior to completion of setting of said heated konjak paste, rapidly cooling the heated paste and thus stopping said setting prior to essential completion of said setting of said konjak paste into a firm gel.
