A practical and efficient oil modification index (OMI) was proposed for classification of oil in terms of its effect on the binder performance grade.
The last major goal in edible oil modification, production of a temperate crop sufficiently rich in saturated fatty acids for use without hydrogenation and its associated trans‐fatty acid production, remains elusive.
The monocarboxylic acids are related to the oil modification and suberic and azealic acid are common oxidation products of a siccative oil [11, 15].
The presence rosin may indicate that oil modification was performed with tall oil fatty acids (TOFA), a by-product from the paper industry which finds major use in alkyds [2, 15].
The mass spectrum showed the characteristic homologous series of ions for a long chain carbon back bone (Δm/z = 14), but whether this compound originates from the oil modification or a paint additive is unknown.
This process, generally named as direct modification of substrate through fermentation (DIMOSFER), was applied for the first time in oil modification.
To the best of our knowledge, the feasibility of this method in any oil modification and fatty acid production has never been reported.
However, no lipolytic activity was detected in the cell filtrate after cell disruption using homogenization, sonication, and normal solvent extraction methods, and only cell-bound associated lipolytic activity was responsible for in situ coconut oil modification.
The results of the present study showed that LipM is unusually highly thermostable, indicating great potential use in various industries including fat and oil modification, cosmetics, pharmaceuticals, organic synthesis, oleo-chemicals and biodiesel production [ 6].
