Biophenols from agro-industrial wastes

Large quantities of agro-based liquid wastes are produced every year and their disposal is often a problem for industries. In light of that, in this study prudent effort was done to screen the agro-industrial wastes - pineapple waste (PAW) and palm oil mill effluent (POME) for valuable biophenols product. Three different solvents; ethanol, acetone and distilled water were screened in order to enhance the process. All experiments were performed using fixed process conditions of solid to solvent ratio, temperatures, time and agitation speed. Effectiveness of extraction process to produce biophenol was based on high amount with more activity. POME was selected as potential source with biophenol content of 125.42 mg/L GAE.
