The curve A in Fig. 1a, representing
the uncontaminated sample of SFO, is found to display two distinct endothermic
transitions at −39.0 and −25.1◦C.The transition at −25.1◦C was associated with a smaller
shoulder peak appearing at −8◦C
It could be very clear that the temperature region from
−5.5 to 50◦C of the heating curve A is found to exist without any significant thermal
transitions
According to previous reports, the DSC melting cure of canola oil (CLO) was
also found to have a similar feature—the temperature region from −5.5 to 50◦C remained
without any thermal transitions
Non existence of a significant proportion of higher melting
TAG molecules in CLO was attributed as a probable reason for this phenomenon
