BIOACTIVE COMPOUNDS, ANTIOXIDANT AND PHYSICO-CHEMICAL PROPERTIES OF JUICE FROM LEMON, MANDARIN AND ORANGE FRUITS CULTIVATED IN SAUDI ARABIA
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.
