2.2. Evaluation of oil stability
Storage stability was monitored by acidity, peroxide and iodine
values and fatty acids' profile. BO viscosity was also compared to
other edible oils.
2.2.1. Peroxide value
The BO peroxide values were determined by AOCS Official
Method Cd 8-53 (AOCS, 1987).
2.2.2. Iodine value
The BO iodine value was determined by the Wijs method AOCS
Cd 1d-1992 (AOCS, 1997a).
2.2.3. Acidity
The BO acidity was assessed according to the method AOCS Cd
8d-63 (1973).
2.2.4. BO fatty acid profile
This analysis was performed according to Christie (1989).
2.2.4.1. Esterification of the samples. Twenty mg of BO samples
were esterified with 14 mL/100 mL of boron trifluoride in methanol
