White interior on loaf - is this mould?

White interior on loaf - is this mould?

Greetings everyone, I am no bread expert nor baker, however I thought that this forum would be the best place to get advice on an issue I’ve been having.I buy my sourdough from my local shop. This is the second time that the interior of the loaf is completely white, “bleached”, looking like mould. I bought the bread and left it overnight in the fringe, slicing it the following day. As you can see by the picture, there is only an outer ring close to the crust that looks normal,What is wrong with this loaf? Is this mould? Would it be because I left it in the fridge?
