| Abstract:
Nutritional attributes like antioxidant activity (AA) and total phenolic content and fruit quality attributes including firmness, colour, soluble solids (SS) content and titratable acidity (TA) were determined for strawberry cultivars, selections and seedlings. The TEAC (Trolox Equivalent Antioxidant Analysis) method has been used to assess the AA of cultivars (ranged from 12.12μmol TE/g FW to 20.50 μmol TE/g FW). Correlation between nutritional attributes TEAC and total phenolic content was found (data not shown). Quality attributes such as soluble solid content and the titratable acidity concentration, in particular their ratio (SS/TA), are important to show how a fruit is balanced (ratio = 1). Our results demonstrate a high variability in quality and nutritional attributes among strawberry cultivars and that these characters can be combined. | |
