Abstract:The quality of two varieties of prune in Jiashi County，Kashi，Xinjiang were studied.The quality differences of two kinds of plum peel and pulp were analyzed by solid content，texture characteristics，sugar acid components，antioxidant ability and color gamut as indexes.The results showed that there were significant differences in fruit quality among different varieties of prune.The quality of the plum peel and pulp of the same variety were also significantly different.“Empress”variety had higher solid content，sugar acid components and total flavonoids than“France”cultivar.The free radical scavenging capacity of polyphenols from prune“Empress”were stronger than that of prune“France”.The IC50values of DPPH free radical，·OH and O2-·scavenging rates of polyphenols from prune“Empress”were 0.65，0.71 and 1.31 mg/mL，respectively.The IC50values of DPPH free radical，·OH and O2-·scavenging rates of polyphenols from prune “France”were 0.71，0.84 and 1.62 mg/mL，respectively.In the texture characteristics，“Empress”variety was more suitable for deep processing or for people with high chewing requirements.However，“France”variety had low hardness and soft texture.Sweet and sour taste of that was more suitable for fresh food.
