Antioxidant activity of black cumin (Nigella sativa L.) and black caraway (Buniumpersicum Boiss) extracts, individually and in combination on chemical changes and sensory properties of silver carp (Hypophthalmichthysmolitrix) stored in refrigerator

Abstract

Herbs due to having natural antioxidant compounds are widely used by food, pharmaceutical and cosmetics industries. The purpose of this study was to study the effects of antioxidant activities of black cumin as well as black caraway extracts individually and in the combination form on chemical and sensory properties of silver carp during refrigerator storage. To do this, fish was cut into four parts. Three parts were dipped in 1% solution of black cumin and black caraway extracts, and their combination. The forth part was dipped in distilled water as a control sample. All fish cuts were packed up in polyethylene bags and were stored at refrigerator (4±1°C). Chemical indices (i.e., PV, TBA and FFA) and sensory properties were measured over a period of 15 days (0, 3, 6, 9, 12, and 15 days). According to the results, in all three treatments lipid oxidation was delayed significantly (p
