Why does fresh bread become dry, firm, and stale after just a few days, even when it hasn't gone bad? In this video, we explore the fascinating science behind bread staling and the chemical changes that occur after baking. Many people assume bread becomes stale simply because it loses moisture, but the real process is far more interesting. As bread cools and ages, the starch molecules inside begin to reorganize and crystallize, changing the texture and making the loaf feel firmer and less fresh over time.
