Description
Effects of 6'0Co γ-rays irradiation on main nutrient components and sensory index of the walnut powder were studied. The results showed that the contents of total sugar, crude protein and crude fat in walnut powder treated by the dose of 2.0-8.0 kGy aren't significantly affected. The content of crude fiber in irradiated walnut powder samples increased, but not significantly. The irradiation changed the contents of the lauric acid and myristic acid, and no significant effects on the contents of palmitic acid, palmitoleic acid, stearic acid, leinoleic acid, arachidic acid and linolenic acid. However, the irradiation made the content of oleic acid increased with the irradiation dose. When irradiation dose reached 8.0 kGy, the content of oleic acid had an increase of 4.3%. Irradiation would not change the sensory index of walnut powder much when irradiation dose is lower than 8.0 kGy.It is concluded that irradiation at the dose lower than 8 kGy could not affect its nutrient and sensory qualities.
