Normally,oil palm fruit bunches are transported to the oil-extracting plant within 24 h after harvest to reduce the increase in free fatty acid (FFA) content which causes low-quality extracted oil. This experiment investigated the effect of ethylene and 1-methylcyclopropene (1-MCP) on the ripening and changes in FFAs of Tenera oil palm fruits. Oil palm fruit bunches were harvested from 11- year-old trees at commercial plot in Sadao district, Songkhla province. There were 4 treatments including 1) control (no ethylene and no 1-MCP)
2) fumigation with 1,000 mlL-1 ethylene for 24 h 3) fumigation with 1,000 mlL-1 1-MCP for 18 h and
4) fumigation with ethylene and 1-MCP. The results showed that ethylene significantly promoted fruit ripening based on accelerate peel color change from black to reddish orange, while 1-MCP delayed ripening.
Changes in FFAs of the control fruits were increased and their FFA content higher than those of the other treatments. Furthermore, oil palm fruits treated with 1-MCP and ethylene + 1-MCP had higher oil content than the control.
