Abstract
Objective: The present study was conducted to evaluate the antioxidant potential of paneer, a soft cheese supplemented with various water soluble date extracts during storage. Further, the whey obtained from all the paneer samples was also investigated for its antioxidant potential.

Methods

The date cultivars were evaluated for their physico-chemical characteristics and date extracts were assessed for their antioxidant potential. Physico-chemical evaluation, microbiological quality and further antioxidant potential of the prepared paneer were carried out during storage period (0-8 days, 5°C).

Results

All the date extracts were found to have considerable antioxidant activity due to presence of total phenolics and flavonoids. Owing to the presence of phenolics and flavoinds in date extracts, supplemented paneer showed higher trolox equivalent antioxidant capacity, reducing power and DPPH radical scavenging activity than control paneer. Paneer supplemented with Rabi extracts had the highest total phenolics (190.7 µg gallic acid equivalent/g paneer), DPPH radical scavenging activity (928.1 µmol equivalent of Trolx/g paneer) and trolox equivalent antioxidant capacity (9.2 µmol equivalent of Trolx/g paneer). The whey obtained from control paneer showed lower values of total phenolics, total flavonoids, DPPH, trolox equivalent antioxidant capacity and reducing power as compared to the values of whey obtained from paneer supplemented with date extracts.
Conclusion
Paneer supplemented with date extracts and its whey may offer potent antioxidant activity.
