摘要: 采用TA-XT Plus质构仪对15个品种的西瓜果皮和果实进行穿刺质地测试,并对获得的力学特性参数与外观物理性状和感官品质进行了相关性分析。结果表明,西瓜果皮的表皮硬度、表皮厚度、表皮破裂做功、外果皮硬度、外果皮穿刺做功、外果皮穿刺最大力和果肉硬度间存在显著的相关性;表皮韧性与果实成熟度负相关,并受到果实形状的影响;果肉质地参数间有一定关联,在感官评价指标中与紧实度关系最为密切,其次是脆度;与水分和纤维的相关性有待进一步研究。

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
