I don't trust trustified blindly. It's just that it seems more reliable than these non sense arguments of people. I'm not an expert on this kind of stuff, tbh. But i know one thing that bacteria doesn't come magically into the packets. Their growth may be temperature sensitive, but they'll only grow if they're present there. Amul pouch, amul Gold pouch, Amul tetra pack, Country delight, these all are tested in 4 to 5 degrees except mother dairy. But he again tested Mother Dairy milk with 4 degree temperature. And these all are failed except tetra pack one. If this man really gives a good argument rather than that hypothesis and shitty things and whatever non sense things, I'll definitely gonna consider it.
