摘要：Tomato (Solanum lycopersicum L.) seeds and skins, which are the wastes of the tomato processing industry, are
often regarded as animal feed in everyday life. In this study, tomato seed oil was obtained by Soxhlet
extractor. The oil yield of tomato seeds was approximately 20.8%. The oils in the transparent, amber and
opaque glass bottles were exposed to sunlight from June to September. The sample intake was made every
20 days and this procedure was repeated 4 times. Each sample was analyzed for fatty acid composition in
gas chromatography. The minimum and maximum rates of the major fatty acids in all of the oil samples
were 54.12-55.72%, 21.68-22.35%, 11.92-12.55%, 6.18-6.63% and 2.39-2.62% for linoleic (C18:2n6c), oleic
(C18:1n9c), palmitic (C16:0), stearic (C18:0) and α-linolenic acids (C18:3n3), respectively. The results showed
that there was no highly variation between the fatty acid rates in all samples.
