Two level half factorial design for the extraction of phenolics, flavonoids and antioxidants recovery from palm kernel by-product

Every year palm oil industry in Malaysia produces enormous quantity of by-products and has great potential to be reutilized as good source of antioxidants. In this study, a two level half factorial design was employed to recover phenolics, flavonoids and antioxidants from palm kernel by-product. The...
