Onion powder
Onion powder is a versatile base ingredient made by drying and fine-milling onion, spreading sweetness and umami evenly into soup powders, seasonings, processed meats, and dressings. The onion-derived sweetness and glutamate-family umami are finished to a size that disperses easily into liquids and powders. At Agriture,Dried onion, we powder it by adding a fine-powdering step.
while raw-material-form onion suits "soups and simmered ingredients where you want to keep texture and the sense of the ingredient," onion powder suits uses where you want to "spread it evenly as a sweetness and umami base." In soup powders, seasonings, and processed-meat products such as hamburg steak and sausage, onion powder has long been adopted as a standard base ingredient.

Three points of care in Agriture's onion powder
Because onion powder is used often as a base ingredient, a clean finish free of scorched or pungent notes decides its quality. At Agriture, we manage everything from pretreatment through milling and packaging at our own processing facility, aiming for a finish with little lot-to-lot variation.
1. Low-temperature drying that produces no scorched notes
Onion is high in sugars, and if the temperature is too high the Maillard reaction advances, producing scorched notes and bitterness. Our top priority is to draw out the moisture slowly at low temperature and preserve the onion's natural sweetness. The benchmark is a state where, the moment you taste the powder, you sense an honest sweetness rather than a scorched note.
2. A finish with controlled pungent components
The way the allyl-sulfide-family pungent components in raw onion remain changes with the drying conditions. We can adjust to the use: a sharp finish that keeps the pungency for seasonings and processed meats, and a mild finish with subdued pungency for soups and dressings. It is a versatile base ingredient that works as the foundation for soup powders, sauces, and seasonings.
A standard ingredient in processed meats
In hamburg steak, sausage, and ham, onion powder is a standard ingredient long in use. It makes moisture control easier than using raw onion and suits mass-production lines.
Dispersibility in liquids and powders
Even dissolved in soups or sauces, the graininess is hard to notice, and it disperses evenly in powder mixes. It can be used as is, with no reconstitution needed.
Pungency can be adjusted up or down
You can choose from a sharp type (for seasonings and processed meats) or a mild type (for soups and dressings). We adjust the drying conditions to the use.
Pre-blending supported
Premixes combining it with salt, pepper, spices, and other vegetable powders are possible. It suits one-stop OEM for seasonings and soup powders.
Use together with the ingredient-shape version
Using it together with dried onion lets you have both sweetness and umami (powder) and the sense of the ingredient (raw-material form).

For uses where you want to keep texture and a sense of ingredient presence, the raw-material form is recommended
For uses where you want to keep the onion's texture, such as ingredients in soups, curries, and simmered dishes,uses where you want to keep the onion's textureare suited to dried onion (raw-material form). Its strength is that it can be rehydrated and used directly as an ingredient.
Commitments to variety, grower, and growing region
Onion is a representative vegetable of the lily family (Amaryllidaceae), grown year-round across the country. As a powder raw material, you can select varieties to match the use, such as sweetness-forward Hokkaido autumn-winter onions, early-harvest onions with strong pungency, and yellow onions with excellent storability.
Main growing region
| Growing region | Features |
|---|---|
| Hokkaido | Top onion producer nationwide. Strong sweetness, suited to heated uses |
| Saga Prefecture | Main production area for new onions. Mild pungency, early-harvest varieties |
| Hyogo Prefecture (Awaji Island) | A brand production area for high-sugar onions. The sweetness stands out even in powder |
| Aichi Prefecture | Main production area for storage onions. Stable year-round supply is possible |
Using varieties and lineages differently
Hokkaido autumn-winter onions (Super Kitamomiji, etc.) grow sweeter when heated and are ideal for soups and sauces. Awaji Island brand onions have high sugar content and suit the base of premium products. Pungent varieties are used for seasonings and processed meats with a finish that keeps the pungency.
Powdering technology and quality control
Onion powder is high in sugars, and the way scorched notes appear changes greatly with the drying conditions. At Agriture, we manage everything from prep through packaging consistently, holding down lot-to-lot variation.
Suppressing scorched notes with low-temperature drying
As the temperature rises, sugars and amino acids react to produce scorched notes and bitterness. Drawing out the moisture slowly at low temperature keeps the onion's natural, clean sweetness in the powder.
Adjusting pungent components
The residual amount of allyl-sulfide-family pungent components changes with the drying conditions. We set the conditions by use: keep them for processed-meat and seasoning uses, and suppress them for soup and dressing uses.
Moisture-resistant packaging
Because onion powder is high in sugars and absorbs moisture easily, the finished powder is moved promptly into moisture-proof packaging. Commercial bulk uses moisture-proof bags, and large bags for processed-meat factories use an oxygen absorber alongside to preserve quality.
TIP: Formulation design in processed meats
In hamburg-steak mixtures, kneading in 1 to 2% onion powder relative to the ground meat sets up a sweetness and umami base even if you skip the step of sauteing raw onion. In sausage and ham, 0.5 to 1% gives an onion-derived richness; in chicken meatballs and paste products, 1 to 3% gives a solid onion presence. Moisture control is easier than with raw onion, and the stable yield on mass-production lines is valued on the vendor side.

How to use the powder and design blends
The raw-material form requires a reconstitution step, but the powder's advantage is that it can be formulated directly into powdered goods. We organize the operational points specific to powders.
Basics of use
- Soup: dissolve 1 to 3 g per 200 ml
- Processed meat: knead in 1 to 2 g per 100 g of ground meat
- Dressing: add 1 to 2 g per 100 g of oil plus vinegar
- Seasoning: blend with salt and pepper at 1:1 to 3:1
- Curry roux: blend in 3 to 5 g per 100 g of roux
Example blend formulas
- Onion soup mix: onion 40% + powder 15% + skim milk 25% + salt and dextrin 20%

Frequently asked questions
How do I use dried onion (raw-material form) and onion powder differently?
The raw-material form suits uses where you want to keep texture and the sense of the ingredient -- as an ingredient in soups, curries, simmered dishes, and stir-fries. The powder suits uses where you want to spread a sweetness and umami base evenly -- soup powders, seasonings, processed meats, and dressings. In some cases both are used together in the same recipe to have both depth of sweetness and the sense of the ingredient.
Which type is good for processed meats?
Is a finish without scorched notes possible?
Yes. By finishing with low-temperature drying, we can produce a powder with a clean sweetness free of scorched notes and bitterness. Raising the temperature to shorten drying time tends to produce scorched notes, so we design for a slow finish that prioritizes quality. Aroma can be checked at the prototype stage. After hearing the specifications, formulation, lot, and schedule of the intended finished product, we propose a quote and lead time on an individual basis. You can consult us end to end, through to finished products such as soup powders, seasonings, processed meats, and dressings.
Please tell me the best-before date and how to store it.
The best-before period is about six months from the shipping date. Before opening, store at room temperature in a cool, dark place away from high heat, humidity, and direct sunlight. Because onion powder is high in sugars and absorbs moisture easily, after opening transfer it to a zip bag or airtight container and use it up within one to two months as a guide. Using an oxygen absorber alongside is also effective.
Can you handle premixes (pre-blending)?
Yes. You can also consult us about an operation where we blend salt, pepper, spices, other vegetable powders, and dashi powder to your specified formulation and deliver a powder close to the finished product. In seasoning, all-spice, and soup-powder OEM, delivery as a premix simplifies the user's production line.
