| Abstract: |
| In order to comprehensively evaluate the quality of sunflower seed oil products in China, and provide reference for product development, refining and purchasing, 11 sunflower seed oil products from 7 brands were collected, and their basic physicochemical properties (acid value and peroxide value), nutrient (vitamin E, phytosterol, squalene) content, hazard (trans fatty acid, polycyclic aromatic hydrocarbons, benzo\[a\]pyrene, 3-chloropropanol ester, and glycidyl ester) levels and flavor characteristics were analyzed. The results showed that there were obvious differences in acid value and peroxide value among different products, but they all met the limit requirements of national standard. Vitamin E and phytosterol were the main nutrients of sunflower seed oil. The average contents of vitamin E and phytosterol were 75.45 mg α-TE/100 g and 4 040.00 mg/kg, respectively. The average content of squalene was 127.40 mg/kg. All products had a trans fatty acid content of less than 0.30 g/100 mL, meeting the requirement of zero trans fatty acid claim. The benzo \[a\] pyrene content in the 11 products met the national standard. The contents of polycyclic aromatic hydrocarbons and 3-chloropropanol ester in 11 products were lower than the EU standard limit requirements, but there was a certain risk of excessive glycidyl ester content. In terms of flavor attributes, four products have distinct flavors, mainly characterized by cooked sunflower seed flavor, burnt flavor and salty freshness.In summary, the quality and safety of sunflower seed oil products available on the market are relatively good, but there are differences in the refining levels and hazard control capabilities among various brands′ factories. At the same time, many brands have begun to introduce flavored sunflower seed oil products. |
