Abstract

Abstract: In order to compare the quality of jujube sold on Tianjin market from different variety, the study selectcd three varieties of Dongzao: Huanghua jujube, Zhanhua jujube and the second generation of Zhanhua jujube and compared the differences of the external quality（single fruit weight, fruit shape index, hardness）and internal quality（water content, soluble solids, soluble sugar, titratable acid, vitamin c）. The results showed that the single fruit weight（28.44 g）, hardness（20.92 kg/cm²）, soluble solid content（16.73%）, soluble sugar content（28.47%）, titratable acid content（0.64%）and Vc content（429.57 mg/100g）of the second generation of Zhanhua jujube were the highest. The fruit shape index（1.04）, water content（83.05%）and sugar-acid ratio （89.69）of Zhanhua jujube were the highest. The fruit quality of jujube was in the order of the second generation of Zhanhua jujube, Zhanhua jujube, and Huanghua jujube according to a membership function analysis.

Key words: Dongzao, quality, variety, fruit
