I dont think that nowdays amul milk is maitining its quality. The taste of milk is changing day by day. I think they are mixing some adulteratives in their milk so that their milk can retain for longer period of time. I think they are not supplying fresh milk everyday but is one or two days old milk. It is not only with milk but also with other products. Earlier I used to be a great fan of amul milk and its other products. But I think amul has lost that trust of mine. Every now and then we read complaints about milk.
