Physical and Chemical Properties of Four Strawberry Cultivars

Physical and chemical properties were measured to study quality of 4 strawberry cultivars, which were fruit weight, firmness, crude protein, juice yield, total anthocyanin, total phenols, total sugar, titratable acid, total soluble solid, pH, water content, electrical conductivity, surface color (L, a, b). The result showed that 15 properties had significantly difference between 4 strawberry cultivars, the variance of these 15 properties ranged from 0.36% to 29.68%. The correlation analysis showed that 15 properties had 5 couple properties significantly correlation (p<0.05), fruit weight and crude protein, juice yield and titratable acid, total anthocyanin and total phenols, titratable acid and surface color a, electrical conductivity and surface color b. The correlation of other properties were not significantly in this study.
