الملخص EN

The aim of this study was to investigate the physiochemical properties of strawberry tree fruits, and to determine the antioxidant characteristics for fresh fruit and some of its prepared products (dried fruits, jam, and canned fruits in syrup).

The average of fruit' s weight and diameter according to the results of the study were 1.12g and 0.98cm respectively, also the percentage of the fruit's moisture was %63.99, total soluble solids %34.07, the ash %0.77, pH 3.77, tetrable acidity %0.88, and reducing suger %14.47.

The results showed that the processing treatment caused a significiant decrease (p>0.05) in ascorbic acid, anthocynin, total phenolics, and antioxidant activity using by the DPPH method in prepared products in comparision with fresh fruits.
