Soybeans, mature seeds, dry roasted

Legumes and Legume Products

USDA FDC 172441 lists 43.32 g protein and 8.1 g fiber per 100 g of unsalted dry-roasted mature soybeans, along with 449 kcal, 21.62 g fat and 1,364 mg potassium. These nutrients can make soy nuts a protein- and fiber-containing snack, but 100 g is energy-dense and soy is a major allergen. The database portion is 1 cup (93 g); salted or flavored products can differ.

What dry-roasted soybeans mean here

The record is Soybeans, mature seeds, dry roasted, not fresh edamame, tofu or soy flour. It describes mature soybeans after drying and roasting; the database serving is approximately 100 g dry roasted. Roasting removes moisture and makes the seed crunchy, but branded snack recipes may add salt, oil, sugar or seasonings. Use the package label when a product contains added ingredients.

Dry-roasted soybeans protein and nutrition per 100 g

The USDA entry contains 449 kcal, 43.32 g protein, 21.62 g fat, 28.98 g carbohydrate and 8.1 g fiber per 100 g. It lists 2 mg sodium, 0 g total sugar, 140 mg calcium, 3.95 mg iron, 205 mcg folate and 1,364 mg potassium. A 30 g handful is about 135 kcal and 13.0 g protein when scaled from this record, before any seasoning is added.

Portions, preparation and storage

Dry-roasted soybeans are ready to eat when sold as a finished snack. Weigh a portion if you are tracking energy because 100 g is a large serving for a snack. Store them sealed in a cool, dry place and follow the package date; oil-containing roasted seeds can develop a rancid smell over time. Do not transfer the unsalted USDA numbers to a salted or coated product without checking its label.

Allergen and diet context

Soybeans are a major food allergen in the United States. Anyone with a soy allergy should avoid the product and check cross-contact information. For other diets, the useful facts are the high protein and fiber alongside substantial calories and fat; whether it fits depends on the person's total meal and portion, not on a blanket healthy or unhealthy label.
