The extraction of papain from papaya leaves
The use of papaya leaves to extract papain enzyme was evaluated for different extraction technique mainly using grinding method, enzyme-assisted extraction and ultrasonication. Enzyme concentration was then determined by measuring the amount of amino acid released in the reaction of protease assay....
