Patent number: 5387425Abstract: There is disclosed a method and composition for enhancing the foam properties of a fermented malt beverage. Briefly stated, the method comprises adding to the beverage an isohumulone extract in the amount of between about 0.1 ppm and about 20 ppm by weight of the beverage and foaming proteins in the amount of between about 2 ppm and about 250 ppm by weight of the beverage. The fermented malt beverage foam-enhancing composition comprises a mixture of isohumulone extract and foaming proteins, wherein the ratio of isohumulone extract to foaming proteins is between about 1 to about 1 and about 1 to about 2500. Further disclosed is a beverage composition with enhanced foam properties which comprises (a) a fermented malt beverage, (b) an isohumulone extract, the extract comprising between about 0.1 ppm and about 20 ppm by weight of the fermented malt beverage; and (c) foaming proteins, the proteins comprising between about 2 ppm and about 250 ppm by weight of the fermented malt beverage.Type: GrantFiled: August 13, 1993Date of Patent: February 7, 1995Assignee: Rhone-Poulenc Specialty Chemicals Co.Inventors: Wen P.

Patent number: 5380542Abstract: A cereal or grain hydrolysate-containing composition which is derived from the enzymatic, e.g., amylase, hydrolysis of cereal or grain in combination with a hydrocolloid, preferably carrageenan or a blend of xanthan gum and locust bean gum, can be effectively used as a fat mimic in preparing low fat comminuted meat products. Thermo-irreversible gels useful for providing non-fat fat mimics can also be prepared in accordance with the invention. In addition to amylase, the enzyme used for the hydrolysis of the cereal/grain substrate can be selected from the group consisting of amyloglucosidases (.alpha. -1,4-glucan glucohydrolase), cellulases (.beta. -1,4-glucanohydrolase), pullulanases (pullulane 6-glucanohydrolase), cyclodextrine glycosyltransferase (.alpha. -1,4-glucan-4-glycosyltransferase), proteases and mixtures thereof.Type: GrantFiled: June 11, 1993Date of Patent: January 10, 1995Assignee: Rhone-Poulenc Specialties Chemical Co.Inventors: Ronald K. Jenkins, James L. Wild
