Description
Five date palm (Phoenix dactylifera L.) varieties, commonly grown in the UAE, were studied for their chemical composition, physical, mechanical and rheological properties. All measurements were made at the 'tamr' stage, the final stage of fruit ripeness. Samples were analysed for sugar, moisture, protein, ash and mineral element contents. Physical measurements as well as mechanical and rheological measurements of the fruit including pitting pressure, shear pressure, and modulus of elasticity were also carried out. Significant differences were observed in the characteristics that were studied, allowing for distinguishable grades among the five varieties. Chemical and physical characteristics of the fruits influenced their mechanical and rheological properties, which in turn can be indicators of firmness and ultimately of quality. Results from this work revealed new and essential information for better understanding of the date fruit that helps to enhance industrialisation and propagation of the best date varieties that satisfy producers' as well as consumers' demands. © 2006 Institute of Food Science and Technology Trust Fund.
