The present work aimed to identify the constituents of the dried whole peel (WP) and albedo layer (AL) of citrus medica (Etrog), as well as their antioxidant activity. The GC-MS analysis of the hexane extract revealed that limonene was the most abundant component (93.9% and 38.09% in WP and AL, respectively), followed by l (+)-Ascorbic acid 2, 6-dihexadecanoate (1.7% and 21.67% in WP and AL, respectively). The antioxidant activity of WP was 91.98% and 93.14% in AL. The appearance, crispiness, flavour, taste, texture, and overall acceptability of biscuits fortified with WP and AL at 3% or 5% were evaluated using 27 panellists. The statistical analysis of sensory evaluation revealed no significant difference in the appearance and flavour characteristics of fortified biscuits with 3% and 5% AL or 3% WP compared to the control. The current findings suggested that fortifying the biscuit with dried Etrog (WP) peel could be done without affecting the taste or sensory acceptance of the product.
