As per the FSSAI regulations, blending of two edible oils is permitted, provided the proportion by weight of any edible vegetable oil used in the blending process is not less than 20 per cent.
Edible Oil industry body COOIT said the move will benefit mustard growers as well as consumers.
Suresh Nagpal, Chairman of COOIT, said mustard growers will get encouragement to increase the sowing area under mustard crop. Higher domestic production of mustard oil will lead to a fall in edible oil imports to some extent, he added.
''Now since there will not be mixing of any other oil, the demand of pure mustard oil will increase,'' Nagpal said.
