Deodorized kapokseed oil foams vigorously when used for deep fat frying around 180°C. This foaming tendency is due to the presence of cyclopropenoid in the oil. It is also known that the concentration of cyclopropenoid in the cottonseed oil is reduced by treatment with carboxylic acid.
In this paper, kapokseed oil was treated with carboxylic acid to improve foaming tendency.
It was found that this foaming tendency could be reduced by treatment with carboxylic acid provided that the cyclopropene ring is not cleaved by bleaching and deodorization prior to treatment with carboxylic acids. Acetic acid and safflower fatty acid were used as carboxylic acids.
Infrared spectra of the acetic acid-treated kapokseed oil showed absorption at 1020 cm-1 which may be associated with the formation of the cyclopropane ring.
