Cucumber and green pepper. Cucumbers and green peppers that have been stored in the refrigerator for a long time will cause frostbite "injury" - blackening, softness, and flavor change. Cucumbers also grow sticky hair.

Bread Bread During the baking process, the starch straight chain part of the flour has aged, which is why the bread develops an elastic and soft structure. As the bread is left for a longer period of time, the amylopectin in the bread slowly associates, and the soft bread gradually hardens, a phenomenon called "aging". The speed at which it "ages" is temperature-dependent.

It ages faster at low temperatures (above the freezing point), while bread hardens faster when it is stored in the refrigerator.
