If we have a function f that has a minimum at a point say x. Does f preserve the min if we convolve it with a mollifier?

No, consider a function $f$ with a graph something like the above for example. (Pardon the rough sketch:) When you mollify it the minimum at the origin will rise and become greater that the value of the mollified function away from the origin.
