In eastern Algeria, the predominant strawberry cultivars (Fragaria×ananassa Duch.) include Savana, Sabrina, and Fortuna. The aim of this study is to evaluate the physicochemical and antioxidant properties of three strawberry cultivars, as well as to characterize two types of strawberry jam. The values of compounds such as caliber, titratable acidity, total soluble solids, moisture, ash, protein, fat, carbohydrate, total phenolic and anthocyanin content, DPPH radical scavenging activity, total sugars and sensory analysis of the jam were determined. The titratable acidity and total soluble solids values demonstrated a significant variation (p˂0.05) throughout all strawberry cultivars. The protein and lipid content of the three strawberry cultivars was less than 1%. The strawberry cultivars contain significant levels of phenolic compounds. Strawberry cultivars have a DPPH free radical scavenging activity ranging from 40.84 to 45.25%. The strawberry jam with ginger (J1) had the highest ratings for all sensory qualities, making it the greatest jam in the judges' view. These findings give useful information on the phytochemical and nutritional quality of Algerian strawberries grown in the eastern region of the country and may be utilized to enhance the nutritional content of a functional food in a healthy diet. |
