Over time, starch molecules shrink and recrystallize, or retrograde, compressing and releasing moisture. That loss of moisture causes soft crumb to turn dry and hard. Temperature abuses during distribution and storage can accelerate the staling process. When it comes to gluten-free flours, the challenge is even harder. Read more
