Abstract: This thesis contains two parts of study. The first part is the investigation of microwave technique in community crude palm oil mill (CCPOM) to replace the heating from steam and hot-air. The steam heating produces a high quality of a crude palm oil (CPO) but has high cost of investment, while the hot-air heating has an inexpensive of investment but provides a poor quality of the CPO. The results from experiment found that the microwave heating had high efficiency of CPO qualities improvement and oil content (OC) increasing. The CPO obtained from microwave heating reduced a free fatty acid content and a moisture content in palm fruit. Microwave heating increased a high OC, carotenoids content, deterioration of bleachability index and vitamin E content in the CPO. The heated palm fruits by microwave kept 2 months, and makes oil properties meet the commercial requirement. The application of the obtained microwave combined with hot-air was applied for the CCPOM. The modified heating produced a high quality of CPO, and reduced the operating time from 15 hrs to 2 hrs and 10 mins. In the second part, the microwave combined with a multi-stage solvent extraction under magnetic stirrer (modified method) were studied to analyze the oil content in fresh palm bunch (OCB) for rapid analysis. This method analysis can reduce the operated time from 72 hrs to 46 mins. The results revealed that the operated time of microwave drying at 850 W was 6 mins. The operated time of oil content analysis spent 30 mins with three times. The analysis was performed under: 1:10 w/v of dried mesocarp to hexane, 55C, 400 rpm of stirring speed and 10 mins of stirring time. Based on validation data of OCB analysis, compared to a standard method was insignificant when using the paired t-test method with high coefficient of determination (0.99 R 2 ). In this study, near infrared (NIR) spectroscopy suitable for palm oil mill was also employed for oil content analysis which implys that the NIR has high possibility to replace the multi-stage solvent extraction and soxhlet extraction.
