Need advice on this
I recently opened a new pack of Amul Unflavoured Whey Protein and noticed this yellowish, thick, paste-like substance stuck to the inside of the lid (attached in the image). The powder itself looks mostly normal, but this residue has me concerned. The pack was sealed when I received it, and I have stored it in a cool, dry place with the lid tightly closed after opening. It doesn't have a very strong or foul smell, but the texture looks unusual and doesn't seem like dry whey powder. I'm not sure if this is just whey protein that absorbed moisture and clumped together, some natural fat separation, or if it indicates spoilage or contamination. Has anyone else experienced something similar with Amul whey, especially the unflavoured version? Is it safe to continue using, or should I stop and contact Amul for a replacement? Any advice or similar experiences would be greatly appreciated. Thank you!
