Abstract Bitter orange (Citrus aurantium L.) is an ancient therapeutic plant. Normally, peels of bitter orange fruit are used as a food ingredient in Thailand, leaving the pulp as waste. This research aimed to develop pasteurized bitter orange juice by studying the effect of dilution and pH on phytochemical contents and antioxidant activity. The bitter orange juice concentrations were prepared at 50, 75, and 100% w/v by DI water and adjusting pH at 2.5, 3.0, and 3.5 by using potassium chloride. The bitter orange juices were pasteurized at 70°C for 5 min. The result showed that 100% w/v pasteurized bitter orange had the highest contents of titratable acidity, ascorbic acid, and total phenolic, approximately 41.60 to 48.67 g/L, 31.26 to 32.26 mg/100 mL, and 54.80 to 57.08 mg GAE/100 mL of juice, respectively when compared to other concentrations. Likewise, antioxidant activity results (DPPH, ABTS, and FRAP) of 100% w/v pasteurized bitter orange juice gave the highest values about 390.58 to 458.15 GAE/100 mL of sample 546.20 to 503.33 µg Trolox/100 mL of sample, and 525.55 to 422.48 µg Trolox/100 mL of sample.
