FAHAD Y. AL-JUHAIMI AND KASHIF GHAFOOR*
Abstract: Juice prepared from lemon (Eureka), mandarin (Kinnow) and orange (Orlando) fruits cultivated in Saudi Arabia were analyzed for different physico-chemical properties, total phenolics, ascorbic acid and antiradical activities. Juices from lemon, mandarin and orange 8.97, 16.1 and 11.78% total soluble solids; 5.73, 1.37 and 1.69% titrable acidity; 79.21, 91.18 and 107.37 mg GAE/100mL total phenolics; 31.24, 53.15 and 53.24 mg/100mL ascorbic acid and 48.3, 59.19 and 61.35% DPPH radical scavenging activities, respectively. The results show that juice from locally grown citrus fruits is of good quality and a valuable source of health promoting constituents.
