Are we consuming fake vegetable cooking oil or mixed oil in the name of any brand?Recently I have seen in news items that the oil what ever oil (Groundnut oil, Rice bran oil, Til oil, Soyabean oil, Sunflower oil etc.) we are buying should cost many more times what we buy usually in the market. Usually in market we get any of the above oils for about Rs.80 to Rs.130 per liter with brand name. Only few companies they sell their oil at very high cost . For example, at present Groundnut oil is available for Rs.95 to Rs.110. But the cost of Groundnuts per kg is Rs.85. To extract one liter of oil, 3Kg. groundnut needed. So to get one liter of oil the cost should be more than Rs.250. But how we are getting for low price. Is it the low mixed oil what we are getting? At my childhood time my grand parents home they used to get til oil by sending till seeds to Ox ridden mill. The oil is very pure with fine fresh smell. So from this we can infer if the vegetable oil is very costly means it is pure? What is the clue behind selling oils at low cost by companies regardless the cost of raw material from which they are extracted?
