Physicochemical Properties Of African Breadfruit (Treculia Africana) Seed Oil Extracted With Azeotropic Mixtures:- Nedolisa Chizoba V
ABSTRACT
The
chemical and physical indices ofAfrican breadfruit seed oil extracted with
absolute solvents (hexane, ethanol, and acetone) and azeotropic mixtures (ethyl
acetate +water, ethanol + water, and petroleum ether + water) were
investigated. The melting points had no significant (p< 0-05) difference
with values in oils extracted from absolute solvent ranging from 17.20 -
30.85°C and values in oils extracted from azeotropic mixtures ranging from
40.27 - 45.30°C. Iodine value ranged from 14.37-24.27 (absolute solvent
extracted) and 16.21-20.60 (azeotropic mixtures). Oils extracted with the
absolute solvents had high saponification and free fatty acid values compared
to the values obtained in oils from azeotropic mixtures. The absolute solvent
extracted oil and azeotropic mixture extracted oil had good vitamin E content.
The absolute solvent extracted oil had a higher smoke points compared to those
of azeotropic mixture extracted oil. Test showed the oil samples obtained, to
be non-drying oil. The presence of water in the azeotropic mixture lead to an
increase in the peroxide value of the oil, making the oil prone to HYDROLYTIC
RANCIDITY.
