Abstract

Physicochemical properties and fatty acids composition of tea seed oil(camellia sinensis O.Ktze.)and camellia oleifera seed oil(Camellia oleifera Abel.)were studied.The appearance,the kernel yield and oil yield of these two seeds were also determined.The results indicated that physicochemical properties of these two oils were similar but the appearance of two seeds was different.The major fatty acids of tea seed oil and camellia oleifera seed oil were oleic acid,linoleic acid and palmitic acid.The content of monounsaturated fatty acids of tea seed oil and camellia oleifera seed oil was 54.12%,75.78%,respectively.The polyunsaturated fatty acids content of these two oils was 24.55%,11.39%,respectively.The oil content of tea seed was 19.88%.The potential annual yield of tea seed oil would reach 15 million tons.The content of essential fatty acid of tea seed oil was 2.15 times more than camellia oleifera seed oil,while the content of unsaponifiable matter of tea seed oil(0.77%)was 22% more than camellia oleifera seed oil.The fatty acids ratio of tea seed oil was balance so that this oil was beneficial for human health.Therefore,tea seed oil has a considerable potential for production and development.
