Claims24
A method of producing an adhesive composition comprising:
- a. admixing sugar, water and a polyfunctional acid to form a mixture, wherein the molar ratio of sugar to water is in the range of 1:20 to 1:60 and the acid is present in the mixture in the range and the acid is present in the mixture at a level of about 5-14% by weight;
- b. heating said mixture to boiling temperature;
- c. maintaining the mixture at boiling temperature until the sugar is substantially cross-linked by the acid to yield said adhesive composition having a Gardner Bubble Viscosity number within the range of 8.3 to 8.7 at 61° C.
An adhesive composition comprising a sugar cross-linked with a polyfunctional acid.
