Abstract
Macadamia (Macadamia integrifolia, M. tetraphylla and hybrids) is a high quality nut with a nutritious, edible kernel. Macadamia is an important horticultural crop in Australia and other countries and Australia is now a world leader in production of macadamia. Research priorities for macadamia have recently shifted from cultural issues to improving quality. Examples of quality issues are insect damage, immature kernels, whole kernel, shoulder damage, weight of pieces, oily and dusty kernels and whether kernels display after-roast-darkening (ARD). The aim of this study was to investigate how kernel ultrastructure, differences in site and season, mechanical dehuskers, delaying harvest, dropping macadamia nut-in-shell (NIS) and the on-farm postharvest handling chain affect kernel quality. The principal quality parameters assessed were roasting quality, oily and dusty kernels, whole kernel, shoulder damage and pieces. Roasting quality was measured by ARD, patchiness of colour and surface damage.
