<![CDATA[The study on oil extraction of avocado fruit has been conducted on the effect of rwa materials and extraction method on the characteristic of avocado oil.There are two method : soaking treatment and fermentation treatment before pressing to separate the oil from avocado fruits.The solvent were hexane,diethyl ather and alcohol, whereas the fermentation times were 3,5 and 7 days.Based on the study the subtances compositions of avocado fruit were 71.72% pulp 9.51% peel and 18.77% seed.The result indicated that the best treatment for oil extraction were obtained by using the diethyl ether soaking of dried fruit and 3 days fermentation of pulp before pressing.The first treatment have produced the yield 37.76% oil,4.20% free fatty acid 2,07 mg/100 gram vitamin E, 102 IU/100 gram vitamin A and 10.3 mg/gram beta karoten while the second treatment has produced the yield 21,44% oil,7,85% free fatty acid ,1,40 mg/100 gam vitamin e ,0,5 IU/100 gram vitamin a and 18,1 mg/gram b karoten.]]>
