Effect of electron beam irradiation on physicochemical properties of sago starch

The effect of electron beam irradiation on sago starch was determined in terms of physicochemical properties. The irradiation dose employed was in the range of 10 to 30 kGy. Peak viscosity was decreasedwhen the irradiation dose was increased. The gel strength was found to be increased when the sago...

Zusammenfassung:The effect of electron beam irradiation on sago starch was determined in terms of physicochemical properties. The irradiation dose employed was in the range of 10 to 30 kGy. Peak viscosity was decreasedwhen the irradiation dose was increased. The gel strength was found to be increased when the sago starch was irradiated at 10 to 15 kGy, thereafter, the value was decreased. Solubility was increased while swellingpower was decreased. Redness, yellowness and free acidity were increased. Intrinsic viscosity, molecular weight and degree of polymerization were also decreased when the irradiation dose was increased.
