| 中文摘要: |
| 为了研究我国市售精炼葵花籽油产品品质差异，采集市售9个主流品牌的16种精炼一级葵花籽油，按标准方法分析其理化品质（酸值、过氧化值、色泽）、营养品质（维生素E、植物甾醇、角鲨烯、谷维素、多酚含量）和安全品质（多环芳烃、苯并（a）芘、塑化剂、2-氯丙醇酯、3-氯丙醇酯和缩水甘油酯含量）。结果表明：不同精炼葵花籽油产品的理化指标存在明显差异；精炼葵花籽油的主要营养素为维生素E（以α-维生素E计）和植物甾醇，含量均值分别达到63.81 mg/100 g和3 867.0 mg/kg；精炼葵花籽油中苯并（a）芘和多环芳烃的含量均低于我国标准限量，62.5%的样品中苯并（a）芘的含量低于欧盟限量（2 μg/kg），87.5%的样品中多环芳烃的含量低于欧盟限量（10 μg/kg）；精炼葵花籽油中的塑化剂检出量较低，而3-氯丙醇酯和缩水甘油酯存在一定超标风险。研究结果说明不同精炼葵花籽油产品的精炼程度和品质控制水平存在明显差异。 |

| In order to study the quality difference of refined sunflower seed oil products in China, 16 kinds of first-grade refined sunflower seed oil from 9 major brands in the market were collected, and their physicochemical quality(acid value, peroxide value, color), nutritional quality(vitamin E, phytosterol, squalene, oryzanol and polyphenols content) and safety quality(polycyclic aromatic hydrocarbons, benzo(a)pyrene, plasticizer, 2-chloropropanol ester,3-chloropropanol ester and glycidyl ester content) were analyzed according to the standard methods. The results showed that there were significant differences in the physicochemical indexes of different refined sunflower seed oil products; the main nutrients of refined sunflower seed oil were vitamin E(calculated as α-vitamin E) and phytosterol, with the average values reaching 63.81 mg/100 g and 3 867.0 mg/kg, respectively; the contents of benzo(a)pyrene and polycyclic aromatic hydrocarbons in refined sunflower seed oil were lower than the Chinese national standard limit, the content of benzo(a)pyrene in 62.5% of the samples was lower than the EU limit of 2 μg/kg, and the content of polycyclic aromatic hydrocarbons in 87.5% of the samples was lower than the EU limit of 10 μg/kg; the detection amount of plasticizer in refined sunflower seed oil was low, and 3-chloropropanol ester and glycidyl ester had a certain risk of exceeding the national standard. In conclusion, there are obvious differences in the refining degree and quality control level of different refined sunflower seed oil products. |
