Optimization of extraction time, temperature, pH and stability on light of dragon fruit (hylocereus polyrhizus) peel / Norfateha Yunos
Dragon fruit (Hylocereus polyrhizus) or known as “buah naga” or “buah mata naga” is one of tropical fruit in Malaysia comes from family Cactaceae. The peel of dragon fruit is often considered as a waste. Therefore, this study was focused at exploring the possibility of using the peel of dragon fruit...
