Freezing, yes but not the fridge.

According to food scientists, the major reason that bread stales is not moisture loss, but rather a process called retrogradation, in which the starch molecules in the bread crystallize. Retrogradation occurs about six times faster at refrigerator temperatures (36 - 40 degrees) than at room temperature, thereby making the refrigerator the worst choice for bread storage. However, the retrogradation process does slow down significantly when bread is stored below freezing temperatures. The water molecules in the bread freeze, which immobilizes the starch molecules and prevents them from forming crystalline structures.
Because retrogradation is accelerated by cold temperatures, it’s logical that it would be reversed by heat. Anyone who has ever softened stale bread in an oven or microwave has witnessed retrogradation reversal. Ovens don’t add moisture, but when stale bread (bread with crystallized starch) is heated to temperatures above 140 degrees, the crystals break down, softening the bread, (140 degrees is the gelation temperature of wheat starch—that is, the temperature at which the molecules form a gel).
