DESCRIPTION
- Refined : Mustard oil shall be obtained by a process of expression of clean and sound mustard seeds of Brassica campestris Linn, (yellow and brown sarson) or Brassica juncea Linn, (Lahi, rai or laha) or Brassica napus (rape or toria), or admixture of these seeds, or by a process of solvent extraction** of good quality of mustard oil cake or sound mustard seeds. The oil shall be refined by neutralization with alkali and/or physical refining/or by miscella refining using permitted food grade solvents followed by bleaching with adsorbent earth and/or activated carbon and deodorization with steam. No other chemical agent shall be used.
- Grad-I : Mustard oil shall be obtained by a process of expression of clean and sound mustard seeds of Brassica campestris linn (yellow and brown sarson) or Brassica Juncea Linn., (Lahi, rai or laha) or Brassica napus (rape or toria) or admixture of these.
- Grade-II : Mustard oil shall be obtained by a process of expression of clean and sound mustard seeds of Brassica campestris Linn., (yellow and brown sarson) or Brassica Juncea Linn, (Laha, rai or laha) or Brassica napus (rape or oria) or admixture of these.
