Due to being rich in healthy fats, how should Amaranth flour or whole seeds ideally be stored to prevent rancidity?

Answer

In a cool, dark place, refrigerated, or frozen

Amaranth seeds and their derived flour contain a significant proportion of healthy fats. Similar to nuts or whole-wheat germ, these unsaturated oils are susceptible to oxidation when exposed to warmth, light, or air, leading to the development of rancidity, which negatively affects both flavor and nutritional quality. To preserve the delicate flavor profile and maintain the nutritional integrity of these fats for extended periods, proper storage dictates keeping the product cool, shielded from light, or preferably stored in a refrigerator or freezer.
