Summary A method is presented for the determining of trace amounts of ethylene oxide in raw copra, copra meal, and coconut oil. The lower limit of detection is 0.3 p.p.m. with an average deviation of 0.2 p.p.m. in the range 0 to 5 p.p.m. The recoveries of added known quantities of ethylene oxide were greater than 90% in nearly all cases. Fumigated raw copra was found to contain small residues of ethylene oxide, but in no instance did the level exceed 4.5 p.p.m. Only half of the coconut oil samples from fumigated copra showed detectable quantities, and all were below 1.5 p.p.m. Nearly all of the meal samples were “none found”. The method should be applicable to all types of edible products.
