Description
Sunflower seed oil shall be obtained either by a process of expressing sound and clean mature sunflower seeds of the plant Helian- thus annus Linn. Fam. Composite or by a process of solvent extraction** of good quality Sunflower seed oil-cake or from sound and clean mature seeds of Sunflower (Helianthus annus). The oil shall be deacidified with alkali and refining by physical refining and/or by miscella process followed by bleaching with bleaching earth and or activated carbon and deodorization by steam. No other chemical agent shall be used. Sunflower seed oil shall be obtained by a process of expression of sound clean and mature sunflower, seeds (Helianthus annus Linn fam. Composite)
