  • Abstract

    Palm oil mill effluent (POME), generated by the oil extraction industry, represents a severe environmental problem due to its highly polluting organic load arising from polyphenol content with low biodegradability. However, with its more than dozens of phenolic compounds, POME is also regarded as a potent source of natural antioxidants. This study describes the improvement in the extraction efficiency of phenolic compounds after pre-treatment with hydrolytic enzymes and microwave irradiated extraction. Enzymatic hydrolysis of POME by various amylolytic enzymes was investigated to reveal the potential coupling mechanism of microwave irradiation-enzyme coupling catalysis (MIECC). It was shown that a 5-6 min extraction time was enough for complete leaching of the phenolic compounds using microwave irradiation. The microwave irradiation extraction (MIE) aided with ragi tapai hydrolysis had 16.3% higher yield of phenolic compounds as compared to microwave irradiation without enzymatic hydrolysis and increase by 34.7% when compared with maceration method
