<![CDATA[Tiwai onion bulb extract (EBT) contain phenol compounds that be used as an antioxidant ingredients. Utilizalion tiwai onion bulb extract as an antioxidant is expected to increase the value and utilization tiwai onion bulbs. This research was conducted to obtain tiwai onion bulb extrect concentration as antioxidant ingredients of coconut oil. Extraction process is done by adding 96% ethanol solvent /0 onion liwai flour and tnen incorporated into tile glass beaker. allowed to stand for 24 hours and then filtered to obtain a liquid extract. Rendement liwai onion bulb extract solvent 96% ethanol is 10,2%. The average value of total phenol content of onion bulb extract tiwai solvent 96% ethanol is 0,043±0,001ppm. Tile liquid extract was then performed vacuum evaporation and the obtained furter extract tiwai and then put in oven vacuum. Extract obtained is then inserted into tne coconut oil, and then analyzed with the parameters of color, odor. proxide number and acid number, with storage time for 3 months. Based on test result, it is obteined that the concentretstions of tiwai onion bulb extract 100-200 mg/kg was able to maintain storage time of coconut oil until the 3 mont period specified in the study.]]>
