About 1 year at 40°F (4°C) or below, according to USDA FoodKeeper v128. That window runs from the day you bought it — FoodKeeper publishes no separate after-opening figure for this one.
Mung bean (dry, food-grade bags) is shelf-stable at room temperature: cool, dry pantry, or refrigerate at 40°F (4°C) or below to keep it longer. Refrigerating it mainly preserves quality rather than safety.
Look for: A rancid or musty smell; Insects, webbing, or larvae in the package; Clumping or visible moisture; Mould, or a slimy surface on cooked grains and pasta. Never taste something to test it — when in doubt, throw it out.
Yes — USDA FoodKeeper v128 gives about 1 year in the freezer at 0°F (−18°C). Frozen food stays safe indefinitely; that window is about quality, not safety.
