2. Vitamin E kontni
Konpozisyon nan vitamin E nan de lwil tounsòl yo te menm bagay la tou, men kontni an nan vitamin E endividyèl yo te diferan. Kontni alpha-vitamin E nanlwil oliv grenn tounsòl segondè oleikse siyifikativman pi ba pase sa yo ki nan lwil oliv tounsòl oleik òdinè. Beta-vitamin E, gamma-vitamin E, ak delta-vitamin E, ak ti diferans.
Kontni an nan -vitamin E nan lwil oliv tounsòl segondè oleik te siyifikativman redwi, ak rezon ki posib pou diferans sa a se diferans lan nan materyèl etid la tèt li, se sa ki, diferans lan nan jenotip.
3. Estabilite oksidatif
Compared with ordinary oleic sunflower oil, the oxidative stability of high oleic sunflower oil improved by fatty acid is significantly improved. The main reason for this change is the change in fatty acid content. Containing lower linoleic acid and linolenic acid is beneficial to improving oil's oxidative stability. The linoleic acid content of high oleic sunflower oil was 11.06 percent , which was significantly lower than the 63.42 percent of ordinary sunflower oil. The oleic acid content of high oleic sunflower oil is 81.23 percent , which is much higher than that of ordinary sunflower oil, which is 24.94 percent . According to the research results, the oxidation rate of linoleic acid is about 10 times that of oleic acid. Therefore, the oxidative stability of high oleic sunflower oil was significantly improved due to the increased oleic acid content and the decreased linoleic acid content in the high oleic sunflower oil.
Rezime
Pi wo a analiz konparatif nan peryòd yo diferan nan de lwil la tounsòl. Rezilta yo te montre ke, konpare ak lwil oliv tounsòl oleik òdinè, kontni an asid oleik nanlwil oliv grenn tounsòl segondè oleikte 56.29 pousan pi wo pase sa yo ki nan lwil oliv tounsòl òdinè. Kontni - vitamin E a te pi ba pase lwil tounsòl òdinè, epi peryòd endiksyon oksidasyon an te ogmante pa 9.58 èdtan.
Asid oleik se yon eleman enpòtan nan lwil legim, ki estab, ki pa -oksidatif epi ki benefisye sante. Lwil tounsòl segondè oleik konsidere kòm yon lwil manjab ki an sante, ki estab, -wo kalite.
