ملخص

Instrumental texture profile analysis (TPA) of nine batches of date flesh with different quality levels was performed and the parameters were related to its physico-chemical properties (i.e., color, mass, length, width of whole date fruit as well as moisture, crude fiber, fructose, glucose, sucrose, and pectin contents). Results of instrumental TPA showed significant linear correlation of hardness with moisture content, crude fiber and pectin content (p<. 0.05), adhesiveness with color a, b values (p<. 0.05) and L value (p<. 0.1), springiness 1 with color b value (p<. 0.1), chewiness 1 with moisture content, length of whole date fruit, crude fiber and pectin content (p<. 0.05), gumminess 1 with pectin (p<. 0.05) and crude fiber (p<. 0.10), elasticity 1 with pectin (p<. 0.05), crude fiber and with color b value (p<. 0.1), and cohesiveness 1 with mass of whole date fruit (p<. 0.10). Principal component analysis (PCA) identified six groups of variables to differentiate the dates and cluster analysis was used to group the products based on the TPA attributes and physico-chemical properties. Dates available in the market can be classified into three different groups namely hard-resilient, soft-springy and firm-adhesive. The results in this study could be used to explore the main instrumental textural attributes important for the classification of dates.
