Abstract: The texture of 15 watermelon cultivars was analyzed using a TA-XT plus texture analyzer through puncture test. The results of analysis and comparison of instrumental mechanical property with physical property and sensory evaluation showed that epidermis hardness, epidermis thickness, epidermis rupture work, exocarp hardness, exocarp puncture work, exocarp maximum force and flesh firmness was significantly positive correlated with each other. The values of epidermis toughness was related to fruit maturity and affected by fruit shape as well. On the other hand, some relationship exhibited among instrumental mechanical properties of watermelon flesh. Instrumental mechanical property showed the closest correlation with firmness, and crispness also showed closer correlation following firmness. Otherwise, the correlation with the juiciness and fibrousness needs further investigation.

Key words: watermelon, mechanical property, texture, quality
