I see. This is like Ajinomoto (MSG) is banned in India.

I've seen a lot of use of tinned food in USA and Europe, I don't think any traditional Indian would like to eat some meat out of box which has months of expiry on it.

Here in our kitchens, you won't find any items , which are boxed or tinned or readymade that has chemical preservatives.

If anything you find preserved is pickle, but that too is preserved by natural vinegar.
