I have a packet of cottage cheese ( paneer ) and it advises me not to deep freeze it? I can't understand why. Any help? I had it deep frozen right from the time I bought it. It is also 3 days past its 'best before' date. Can I still use it? 
I have seen frozen paneer before. It is certainly not a good Idea to Freeze it. It turns yellow(off-whitish, due to the acids used in separation of cheese from milk) and loses texture ( as mentioned by @tsturzl ). When you thaw it if you find a lot of difference in taste and smell than that would be because it's past best before date. Paneer normally has very mild sour-milky odor with firm white texture and tastes bit like tofu bit milder.
