Selecting, storing & prepping soybeans
- Selecting
- Dried soybeans should be uniformly pale yellow with smooth, unwrinkled skins; edamame is the same plant harvested young and green, while dried soybeans are left to mature and dry on the vine.
- Storing
- Dried soybeans keep up to a year in a sealed container in a cool, dry pantry. Cooked soybeans keep 3-4 days refrigerated or up to 6 months frozen.
- Prepping
- Soaking dried soybeans for at least 8 hours before cooking is important, since they're notably harder and slower-cooking than most other dried beans.

Key metrics
Nutrient density
Per 100 kcal, soybeans delivers about 1% of a Daily Value on average across 22 beneficial nutrients. The score is its percentile for that measure among the 177 foods in our database — higher means more nutrition per calorie. How this is calculated.
Density counts protein, fiber, and vitamins and minerals (not fat, sodium, or sugar), each capped so a single nutrient can’t dominate, with a calorie floor so very-low-calorie foods aren’t overstated. It measures nutrition per calorie within our database — a useful guide, not a complete verdict on how “healthy” a food is.
