The method is simple to perform and produces an oil which can be employed directly in margarine manufacture. The oil can be a mixture of an oil high in pufa such as natural sunflower and safflower seed oil and an oil high in safa such as fully or partially hardened sunflower or safflower seed oil.Other References
