1. Introduction

In our increasingly aging society, the prevention of cardiovascular diseases, Alzheimer’s disease and other chronic diseases has become a significant issue for physicians worldwide. Voluminous research indicates that lipid nutrition has a significant impact on the development of cardiovascular diseases. Excessive fat intake is considered an important risk factor for cardiovascular diseases. In contrast, the dietary intake of edible oils with suitable structure and function could delay the onset of cardiovascular and other chronic diseases. Fatty acids from different sources have different carbon chain lengths, numbers of double bonds, and double-bond positions, and therefore exhibit different chemical and physical properties. Due to the high content of fatty acids (about 95%) in oils, the composition, saturation, chain length, and double-bond location of the fatty acids in triacylglycerides (TAGs) have been thought to be associated with the nutrition of edible oils for some time [1]. Moreover, because of variable stereospecific distributions, fatty acids sharing the same structure and composition may exhibit different effects on the absorption and metabolism of the TAG [2,3]. With the development of techniques to measure the acylated position of different fatty acids (i.e., the stereospecific number, SN), the position of fatty acids on the glycerol backbone can now be effectively determined [4,5]. Measuring the distribution of acylated fatty acids in a TAG is important for improving the TAG structure, optimizing its physicochemical properties, and enhancing the nutritional value of an edible oil in order to develop more healthy oils for human consumption. Modifying the fatty-acid composition of rapeseed oil is an important goal of rapeseed breeding [6]. With previous success in breeding low-erucic-acid and low-glucosinolate rapeseed cultivars, current research focuses on breeding high-oleic cultivars because high-oleic oil can reduce low-density lipoprotein (LDL) and lower cholesterol levels in the blood—effectively reducing the risk of developing cardiovascular diseases, and in some cases, cancer. In addition, vegetable oils with high-oleic-acid content are highly desirable with respect to thermal stability, easy oxidation, and longer shelf life. Our group has successfully developed a rapeseed strain by means of γ-60 ionizing radiation that can be used to produce high-oleic oil (more than 80% oleic acid content) [7–10]. After continuous self-breeding and the selection of agronomic traits, several inbred cultivars with stable characteristics were established. However, the molecular structures of the TAGs and the nutritional quality of these strains have not been studied until now.
