茶叶籽油耐贮，但尚未有学者深入探究其原因。依据前人研究及课题组工作基础，极性油脂伴随物被确定为最主要抗氧化因素之一。本项目以茶叶籽油极性伴随物为研究对象，针对其于茶叶籽油自动氧化时的抗氧化贡献及组分间的作用类型与机制等关键问题，通过建立自动氧化模型，确定判定组分间作用类型的方法，并将极性油脂伴随物单体分类：互作组（增效、协同、拮抗）、非互作组（加和）。针对互作组依次探寻双组分、三组分直至全互作组分在不同氧化时期的抗氧化作用，逐步研明互作组分间的作用类型；非互作组，于自动氧化的不同时期分别建立INFCIM模型。结合脂肪酸及其一级、二级氧化产物、自由基等的动力学方程，阐明互作和非互作机制。综合互作和非互作结果，全面研明极性油脂伴随物抑制茶叶籽油自动氧化的作用机制。本项目的研究思路在油脂抗氧化相互作用基础研究领域鲜有报道。如取预期成果，将为揭示多组分混合物影响油脂自动氧化的作用机制提供借鉴。

Tea seed oil is storable, yet no one has explored the reason deeply and systematically. Based on related literature and our previous work foundation, polar components of tea seed oil are identified as one of the major factors. This project plans to select polar components of tea seed oil as the research object. To study their antioxidant contribution, interaction and interaction mechanism among different contents during automatic oxidation of tea seed oil, we intend to determine the method which can judge action type on a model of the auto-oxidation of tea seed oil. Then the monomer would be classified into interaction groups (enhancement, synergism, antagonism) or non-interaction group (additive). On this basis, the interaction type of two components, three components until the whole components from interaction groups in the different periods of the auto-oxidation would be explored. In non-interaction group, we would establish the INFCIM model in the model induction period and oxidation period respectively .What’s more, we want to combine interaction type with the kinetic changes of the fatty acid, free radical etc to illuminate the mechanism of interaction and non-interaction. Finally, combining with the results of the interaction and the non-interaction, we plan to expound the regulating mechanism of tea seed oil polar components when the tea seed oil oxidation automatically. The research train of thought proposed in this project is rarely reported in the antioxidant interaction basic research. The expected results are to provide new research though for making the antioxidant mechanism of the multicomponent mixtures in the oil clear.
