Oxidative stability of crude and refined kenaf (Hibiscus cannabinus L.) seed oil during accelerated storage

Kenaf seed oil has been suggested to be used as edible oil but there is limited information available about the oxidative stability of refined kenaf seed oil. An oxidative stability test was performed on crude and refined kenaf seed oil under accelerated storage at 65ºC for 24 days. The results show...
