Determination of Trace Element Nutrition and Risk Assessment of Heavy Metals in Se-Enriched Camellia oleifera by ICP-MS

Camellia (Camellia oleifera A Bel), regarded as tea seed tree, is an important woody oil tree species originated in China.Camellia seed oil from tea seed oil is a kind of high-quality natural-health edible oil, which be loved by the vast number of consumers.Camellia oil is mainly distributed in 18 provinces in South China, Hunan, Jiangxi, Guangxi, Guizhou (area), whose cultivation area is ca.3.67 hm × 106 hm with an annual output of ca.200,000t of camellia oil.Camellia oleifera seed contains high nutrition, so it is extremely vital significant to its in-depth study 1 .With the development of modern living standard, people's demand for edible oil nutrition and health care are also more and more high.Selenium is important in scavenging free radicals, antiaging, anticancer element, so the Camellia oleifera after enriching selenium should improve the quality of Camellia oleifera oil 2 .However, selenium-enriched tea has not been done, it is very important for the evaluation of changes of nutritional components and harmful components in Camellia oleifera after selenium enriching.This paper studies the changes of trace elements and heavy metals contents of Camellia oleifera seed after selenium enriching, provide technical support to production and application of Se-enriched Camellia oleifera.Select cultivars Cen soft No. 3 (Guangxi cultivars) with a certain number of fruit for experiment in Nanning of Guangxi
