| Abstract: |
| To provide reference for the low-temperature storage of sesame seed oil, the storage tests of sesame seed oil (aqueous extracted fragrant sesame seed oil, pressed fragrant sesame seed oil, and refined sesame seed oil) were conducted at low temperature (15 ℃), room temperature (25 ℃), and high temperature (45 ℃), and the acid value, peroxide value, and the contents of vitamin E, sterol, and sesame lignan in the sesame seed oil during storage were determined to analyze the effects of different storage temperatures on their quality preservation. The results showed that after 196 d of storage, the peroxide values of the three kinds of sesame seed oils stored at 45 ℃ increased to 0.41-1.80 mmol/kg, and the acid values increased to 0.32-2.23 mgKOH/g. The peroxide values and acid values of the three kinds of sesame seed oils stored at 15 ℃ were reduced by 51.7%-75.6% and 36.9%-56.3%, respectively, compared with those stored at 45 ℃, and the peroxide values and acid values of the three kinds of sesame seed oils did not exceed the national standard limit. The loss of vitamin E in three kinds of sesame oils stored at 15 ℃ was 6.7%-15.8%, compared to 208%-23.0% at 45 ℃. Sterol loss at 15 ℃ was 18.5%-29.8%, compared to 21.2%-31.2% at 45 ℃. The sesame lignan content in sesame seed oil had no change during storage at different temperatures. In summary, the storage of oil at 15 ℃ has obvious effects on inhibiting the increase of peroxide value and acid value of sesame seed oil and reducing the loss of vitamin E and sterol, and low-temperature storage can be used as an environmentally friendly approach to preserve sesame seed oil quality. |
