India does not have a 'large vegan populatiion', it has a large 'vegetarian' population with milk, yoghurt (we call it curd/ dahi), paneer (cottage cheese), and ghee a part of the daily diet. Vegetable fat/ oils used in cooking instead of ghee are usually either raw or filtered or refined. Interestified vegetable oil/ fat is a relatively new product and is used by FMCG co.s as a replacement for palm oil in their products. Interestified vegetable oil also tastes nothing like ghee. Don't take my word for it, try it out yourself.
Any Indian touting vegan ghee will get laughed out of their home and get told to use the real thing.
