Preparation of Oil Palm Empty Fruit Bunch Hydrolysate

Malaysia is the second largest palm oil producer and exporter globally. When crude produced in both plantations processing mills, a large amount of empty fruit bunch (OPEFB) simultaneously as waste product. Here, we describe preparation hydrolysate from OPEFB. After OPEFB was hydrothermally treated at 180–200 °C, resultant liquid phase subjected to high-performance chromatography analysis, while solid used for acidic enzymatic hydrolysis. Hemicellulose yield acid-treated decreased 153 mg/g-OPEFB 27.5 by increasing hydrothermal treatment temperature 180 200 °C. Glucose enzyme-treated obtained after °C highest (234 ± 1.90 mg/g-OPEFB, 61.7% production efficiency). In contrast, xylose, mannose, galactose, arabinose yields prepared were lowest. Thus, concluded that optimum pretreatment which caused low hemicellulose yield. Based on these results, have established an effective method preparing hydrolysates with high glucose content.
