Amul is a famous milk and dairy products company in India( Gujrat) . It was the most famous company for its dairy products but nowadays the products are not good as expected.
In our family we all used to drink Amul Gold milk ( Cow) and use all dairy products . One day when my mom had boiled the milk and then kept in the fridge for cooling , we get a thin layer of ice cote on the milk cream .this indicates that there is addition of water on milk.
I think they are trying to increase their funds by spilling the product. Also some time the milk is not fresh.
This is the reason why I dont drink amul milk nowadays.
