Abstract

Previous studies proved the antioxidant properties of dates. However studies on date byproducts especially date vinegar are still lacking. Hence it is the aim of the present study to compare the physicochemical properties total phenolic content and antioxidant capacity between homemade and commercial date vinegar. Physicochemical properties such as total sugar content pH and total titratable acidity of homemade and commercial date vinegar were studied. Both homemade and commercial date vinegar showed significant difference in physicochemical properties including pH sugar content and total titratable acidity (p0.05). Total phenolic content ranged from 281.17 mg GAE/L to 641.17 mg GAE/L with significant differences (p0.05) noted between homemade and commercial date vinegar. Homemade semisoft date vinegar possessed significantly higher (p0.05) hydrogen peroxide inhibition capacity (310.20 g AAeq/mL) as compared to soft date vinegar (200.06 g AAeq/mL) and commercial date vinegar (190.81 g AAeq/mL). Pearsons correlation statistical test showed no significant correlation (p0.05) between hydrogen peroxide scavenging activity and total phenolic content of date vinegar. Only the homemade date vinegar showed metal chelating property with values of 0.34 0.10 and 2.90 0.03 for semisoft and soft date cultivars respectively. Pearsons correlation statistical test showed significant correlation between metal chelating rate and total phenolic content (r0.50; p0.01) of the two samples. Homemade date vinegar showed generally higher antioxidant activity than commercial date vinegar and both samples were significantly different in terms of their physicochemical properties.
