Onion Powder

What Is Onion Powder?

Onion powder (Allium cepa) is a spice obtained by finely grinding sliced, dried onion. It has a sweeter, more balanced, and less sharp aroma than fresh onion.

Due to its long shelf life and easy measurability, it is especially preferred in dry spice blends and soup and sauce powders.

Nutritional Value of Onion Powder

Onion powder contains approximately 341 kcal of energy, 10.1 g protein, and 79.1 g carbohydrate per 100 g; it is also notable for its potassium content. Since the amount used in a recipe (tsp scale) is small, its practical contribution to daily nutrition is limited.

Onion, fresh or powdered, is traditionally considered part of a balanced diet; research is ongoing into its sulfur compounds and flavonoids.

This information is general; onion powder is a spice and is not a substitute for medical treatment.

How Is Onion Powder Selected?

Quality onion powder should be free-flowing, a homogeneous cream color, and have a distinct scent; clumped, darkened, or scentless onion powder should be avoided.

• The color should be cream-beige; darkening indicates staleness.
• Releasing a distinct onion scent when opened is a sign of freshness.

How Is Onion Powder Stored?

Onion powder can be kept for 2–3 years in a closed jar in a cool, dry place. Moisture causes both clumping and a rapid decline in aroma.
