Processes for producing virgin coconut oil. coconut cooking oil and raw material for coconut biodiesel

摘要

Virgin coconut oil, cooking oil and coconut oil for biodiesel are obtained by irradiating fresh coconut milk with microwave. Depending on the desired end-product, the optimum set up of microwave power, time and temperature are electronically controlled accordingly. Virgin oil requires a microwave power setting of 50 to 1500 Watt at a frequency of 300 MHz to 20 GHz and a temperature range of 40 to 60 °C for a period of 10 to 60 minutes, while cooking oil requires a temperature range of 60 to 80° C and coconut oil for biodiesel, between 80 and 100 °C, The oil is separated from the irradiated milk by gravitational or centrifugal means.
