Instrumental Measurements and Texture Evaluation on Fruits from Three Varieties of Zizyphus mauritiana

Three Zizyphus mauritiana cultivars' (Cuimi, Gaolang No.1 and Taomi) fruit texture at different maturity have be determined using texture analyser, and the differences in fruit texture among three cultivars and different maturity have been analyzed to reveal the changing rules of the fruit texture of Zizyphus mauritiana. The results showed that:pericarp break force was significant positive correlation with pericarp brittleness and pericarp toughness, positive correlation with flesh firmness, Flesh firmness was significant negative correlation with fruit adhesiveness and resilience. From 70% to fully maturity period, pericarp break force, pericarp brittleness and flesh firmness gradually decreased, fruit adhesiveness and resilience of three cultivars have different trends. In fully maturity period, Taomi has the highest pericarp break force and pericarp brittleness, Gaolang No.1 has the highest flesh firmness, Cuimi has the highest fruit adhesiveness and resilience. There was no significant difference of the pericarp brittleness among three cultivars.
