Abstract: |
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. |
