  • How to extract sesame oil in Iran?
  • In Iran, despite from the cold press method to extract the sesame oil, the traditional extraction method had been performed from ancient times. In the traditional method, the sesame hulls remove by soaking the sesame seed in solution of water and salt.‌
  • How is sesame oil extracted?
  • The sesame seeds were put into a cold presser (temperature less than 40–45°C), and the oil was extracted under low pressure. Extracted oil was stored in storage tanks, and subsequently, oil filtration was conducted to isolate the waste. A sample of crude oil (virgin sesame oil) was prepared from sesame oil without further treatment.‌
  • How do you make a sesame oil?
  • In the traditional method, the sesame hulls remove by soaking the sesame seed in solution of water and salt. The dehulled seeds would be roasted and grinded to produced Ardeh (Tahineh) which in combination with water and further squeezing produce the Ardeh oil (sesame paste oil) (Shahidi, 2005 ).‌
  • How to make Ardeh oil?
  • The oil samples were produced according to Figure 1. In order to prepare Ardeh oil (sesame paste oil), the sesame seeds were soaked in the mixture of water and salt to remove the hull. The dehulled sesame seeds were roasted at temperature less than 200°C, followed by grounding the sesame seed to produce sesame paste.‌
  • Is oil extracted from whole sesame seed stable in oxidation?
  • It was shown that oil extracted from whole sesame seed without dehulling could be stable in oxidation which is in agreement with results of Kamal-Eldin (Kamal-Eldin & Appelqvist, 1995) and Konsoula (Konsoula & Liakopoulou-Kyriakides, 2010 ), although it was not in agreement with Tenyang results (Tenyang et al., 2017 ).‌
  • Why do sesame seeds have a high peroxide value?
  • The hull of sesame seed is rich in antioxidant compounds, and during oil extraction, antioxidants would transfer into oil and increase the oxidative stability (Abou-Gharbia et al., 1997 ). Thus, the high peroxide value in Ardeh oil could be attributed to dehulling process of sesame seeds and heating during extraction.
