ABSTRACT :
Bruising is a common problem in harvest and postharvest handling when crops are transferred from one operation to the next. Cushioning and velocity control devices are used to avoid bruising in handling systems. A cushioning material must provide effective energy absorption and dissipation and not create the critical stress/strain level in the produce tissue that will initiate bruising. Inadequate cushioning can cause larger bruises than a hard surface. ASTM (American Society for Testing Materials) stiffness values which indicate that a cushioning material provides 25% deflection are inappropriate for selecting materials to protect sensitive produce from bruising during impacts. Comparison of the dynamic stiffness response and the ASTM stiffness values of several cushioning materials with regard to fruits and vegetables are presented.
