Ultrasonic extraction of antioxidant compound in guava

The antioxidant such as ascorbic acid (AA) in guava juice has attracted a lot of interest from the public and herbal industries because of the antioxidant can inhibit the oxidation of body cells that can lead to health problem. The work done in this research investigates the most suitable operating...
