Two novel synthetic antioxidants for deep frying oils

Lauryl tert-butylated hydroquinone (LTBHQ) and its oxidized compound, lauryl tert-butylated quinone (LTBQ) were synthesized from tert-butylated hydroquinone (TBHQ) and lauryl alcohol. Their antioxidant activities were investigated. At temperatures higher than 140 °C, the antioxidant activity of LTBHQ and LTBQ was higher than TBHQ. In emulsions, these two compounds had stronger antioxidant activity than TBHQ, butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA).
