  • Does industrial refining of soybean oil reduce tocopherol content?
  • In fact, industrial refining of soybean oil reduced the tocopherol content of the soybean oil from 132.92 to 119.09, while the content of tocopherols in the refined oil using the electrostatic field did not change significantly (Table 4 ).
  • How much tocopherol is in soybean oil?
  • Soybean contains1328 mg/kg tocopherol, which is highestamong plant oils. Total tocopherol contents gradually decreased until the end of the re?ning processes in all oil types. The content of α-, β-,γ- andδ-tocopherols also decreased during re?ning. These signi?cant losses occurred especially after the deodorizing stage.
  • Are and -tocopherols found in soybean oil?
  • According to the NP-HPLC analysis, results show that α- and γ-tocopherols were found in higher concentrations in soybean crude oil and smaller concentration in deodorized oil. In the present study, we have determined four types of tocopherols such as α-, β-, γ-, and δ-tocopherols in each processing samples.
  • Does refining process affect tocopherol content of vegetable oils?
  • In this study, the effect of different steps in both chemical and physical re?ning process on tocopherol contents of several vegetable oils(sun?ower oil, corn oil, rapeseed oil, soybean oil, olive oil and re?ned-bleached-deodorized (RBD) palm oil) was investigated. The mostcommonly tocopherols found in vegetable oils wereα- and γ-tocopherols.
