text: The best extraction conditions of melanin is that, hydrochloric acid soak time 5 h, alkaline solution pH value 14, extracting time 20 min, extraction temperature 70 °C, absorbance value about 0.309 A. Melanin from banana peel is stable at high temperature, different light source irradiation, reducing agent coexist; but at room temperature, metal ions and oxidizing agent coexist, it is unstable.
