Functionality of a mixture of gums from Acacia glomerosa, Enterolobium cyclocarpum and Hymenea courbaril in the low fat ice-cream preparation

Abstract:

Acacia glomerosa, Enterolobium cyclocarpum and Hymenaea courbaril, species widely disseminated in Venezuela, South America, produce gum with good yield. The mixture of these gums was tested as stabilizer in the low fat ice cream preparation. Viscosity, overrun, foam expansion, meltdown, shape factor and sensory properties were determined. These quality characteristics were compared with those exhibited by the product obtained with a mixture of commercial gums. The mixture tested provided the suitable viscosity for the ice cream mix with the corresponding overrun and texture. It gave better foaming properties and air incorporation. On the other hand, it was demonstrated the good sensory attributes by the highest score i.e. appearance (7.78), creaminess (7.62), flavor (8.01) and lowest score of iciness (3.06). This work showed good functionality as stabilizer of the mixture of gums investigated in the low fat ice cream preparation.
