Quality changes in macadamia kernel between harvest and farm-gate.

BACKGROUND: Macadamia integrifolia; Macadamia tetraphylla and their hybrids are cultivated for their edible kernels. After harvest; nuts-in-shell are partially dried on-farm and sorted to eliminate poor-quality kernels before consignment to a processor. During these operations; kernel quality may be lost. In this study; macadamia nuts-in-shell were sampled at five points of an on-farm postharvest handling […]

Dropping macadamia nuts-in-shell reduces kernel roasting quality

BACKGROUND: Macadamia nuts ('nuts-in-shell') are subjected to many impacts from dropping during postharvest handling; resulting in damage to the raw kernel. The effect of dropping on roasted kernel quality is unknown. Macadamia nuts-in-shell were dropped in various combinations of moisture content; number of drops and receiving surface in three experiments. After dropping; samples from each […]

The lipid messenger OEA links dietary fat intake to satiety

The association between fat consumption and obesity underscores the need to identify physiological signals that control fat intake. Previous studies have shown that feeding stimulates small-intestinal mucosal cells to produce the lipid messenger oleoylethanolamide (OEA) which; when administered as a drug; decreases meal frequency by engaging peroxisome proliferator-activated receptors-alpha (PPAR-alpha). Here; we report that duodenal […]
