摘要
为了解番茄果实在绿色、转折期和红熟期的破裂力，测定了番茄果实的压缩力-变形特性。随后进行了模拟运输研究，采用部分析因实验设计，研究了振动、压缩载荷和容器类型对机械损伤的影响。力变形研究表明，成熟导致番茄生物屈服点，韧性和硬度显着下降，并增加了顺应性。在模拟运输试验中，番茄成熟度、容器类型、振动和压缩载荷对机械损伤有显著影响。结果表明，在运输过程中对产品施加均匀的中等压力，可以减少冲击损伤的发生。这些研究结果的影响，在设计和一般的改进包装容器用于运输易腐农产品在发展中国家进行了讨论。
Summary.
The compressive force-deformation characteristics of tomatoes in the green, turning and red stages were determined with a view to obtaining information on the rupture force for these fruits. This was followed by a simulated transit study which investigated the effects of vibration, compressive load and type of container on mechanically induced damage, using a fractional factorial experimental design. The force-deformation studies showed that ripening leads to a significant decrease in tomato bioyield point, toughness and firmness and an increase in compliance. In the simulated transit study, mechanical damage was significantly affected by the stage of tomato maturity, container type, vibration and compressive load. It was found that the appli-cation of uniform moderate pressure on the produce during transportation would reduce the incidence of impact damage. The implications of these findings in the design and general improvement of packaging containers used for conveying perishable agri-cultural produce in developing countries are discussed.
