Ultrasonic extraction of antioxidant compound from red pitaya
The health benefit of antioxidant’s activities from the betacyanin contents in red Pitaya, attract a lot of interest from the public, food as well as pharmaceutical industries. This natural antioxidant from red Pitaya can replace the dangerous synthetic antioxidant at the market. The works done in t...
