Effects of Different Media on the Characteristics of Ginkgo Starch Gelatinization

Abstract:

The infections of different media such as concentration, salt, sucrose, citric acid, shearing force on the starch gelatinization characteristics of Ginkgo nut was studied through Rapid Visco Analyser (RVA) SuperIII. The results showed that the best speed for the determination of starch paste viscosity curves was160 r/min; along with the increased in the concentration of starch milk, starch paste viscosity increased and thermal stability declined; salt and citric acid could reduce the starch paste viscosity and enhance the anti-aging capability and sucrose could also improve viscosity and prolong the gelatinization time. The result on the Gingko nut deep processing of starchy foods has great significance.
