antistaling agent

Antistaling agents are chemical additives used in baked goods to prevent or slow down the staling process. Staling involves undesirable changes in texture, flavor, and appearance, most notably the firming of the crumb in products like bread. This firming is primarily due to changes in the molecular structure of starch, where sections of long-chain molecules aggregate, making them more rigid.1

Antistaling agents, such as monoglycerides of fatty acids or glyceryl monostearate, are often starch-complexing agents. They are thought to work by preventing water loss from starches, thereby maintaining the softness and moisture of baked goods. While heating can temporarily soften stale bread, it doesn't fully restore its original texture.12
