unbleached 面粉就不白，我一直买这种面粉，不爱买漂白面粉

Unbleached flour is flour that ages naturally after milling, resulting in a denser grain and an off-white color that dulls with age. It's often preferred by professional bakers for its richer flavor and higher nutritional value. Production: Unbleached flour is naturally aged, while bleached flour uses chemical treatments to speed up the whitening process.
