Abstract
Using synthesized trilinolein, the relations between the foaming tendency after heated and the chemical characteristics were studied. Trilinolein after heated for 5 and 9hr. at 200°C, showed slight and severe foaming tendencies respectively. From trilinolein heated for 5 and 9hrs., monomeric, dimeric and secondary product fractions of fatty acids were separated, and chemical, infrared and thin-layer chromatographic analyses were carried out there of. The number of functional groups in their mean molecular weight were also calcurated.
From these results, it was concluded that the substances formed by heating are different in both quantity and nature by the lapse of heating time.
