What is the cultural significance of an edible defect?

I’m not sure how to phrase this. When you get a burnt cheez-it or an extra chicken nugget. An oreo with the design of one half pressed into the cream, a dorito totally loaded with msg powder. These edible defects in factory produced junk foods and errors in the fast food industry. I want to write about this for a class. Is the moment of discovery when finding one of these tragic or triumphant? Could this moment be used to define the human condition, or? Help me out please.
