Abstract
Dehusking to remove the fibrous husk of the macadamia fruit is an essential first step in postharvest handling of macadamia nuts (nut-in-shell). Dehusking is accomplished with mechanical dehuskers with associated trauma for nut-in-shell. Mechanical dehusking of high moisture content fruit causes shoulder damage but it is unknown how dehusking partially dried fruit after slow drying affects kernel quality, or whether dehusking affects roasted kernel quality. Macadamia fruit was dehusked at field moisture content (23%) and at lower moisture content (10-12%) after slow drying. Dehusking at lower moisture content reduced whole kernel, increased shoulder damage, increased weight of pieces and increased after-roast-darkening (dark kernels). Slow drying similar to delayed harvest was more important to reduced quality than the type of dehusker. Improving harvest management by reducing time between harvest rounds is more important to macadamia kernel quality than the type of dehusker used.
