For most food manufacturing, white dehydrated onion is the right choice. It has a neutral colour, the widest range of forms and the most reliable supply.
Red or pink onion makes sense when the customer can see the onion and the colour adds something, such as on a salad topping or in a visible seasoning. In blends and sauces where the onion disappears, red usually adds cost without adding value.
Matching colour to use
- Soups, sauces and gravies: white. Pale colour keeps the product looking as intended.
- Snack seasoning and spice blends: white powder or granules are standard. Colour grade matters less once blended.
- Processed meat, sausages and burgers: usually white powder, granules or minced.
- Ready meals and meal kits: white flakes or chopped, with a tighter colour grade where pieces are visible.
- Salad toppings, dips and dressings: red or pink can add visual appeal. White is also common.
- Retail onion flakes in jars: often white, where colour grade and uniformity matter a lot.
Colour grade matters as much as colour
Within white onion, plants sell several colour grades. A visible product needs a better grade with few dark or brown pieces. A powder for a dark sauce can use a lower grade. Our guide to Grade A versus Grade B dehydrated onion explains the difference.
Choosing a better grade than you need costs money. Choosing a worse one shows up as specks in your product and complaints from your customer. The cheapest grade that passes your own test is usually the right one.
Questions to answer before you choose
- Will the onion be visible in the finished product?
- Is the product cooked, and for how long? Long cooking can darken any onion.
- What other colours are in the product? Dark sauces hide more than white sauces.
- Will it be stored in clear packs under light? Coloured onion can fade.
- How much will you need each year? Red and pink supply is smaller and more seasonal.
- Does your customer have a colour specification of their own? If so, work back from it to the grade you buy.
Test in the finished product
A sample that looks good in a bag can behave differently in a recipe. Rehydrate it, cook it the way your process does, and look at it next to your current material. Do this with at least two colour grades so you know the lowest one that passes.
Once you choose, keep a reference sample on both sides. Colour is hard to describe in words, so the reference is what future shipments are checked against. Pre-shipment and approval samples explains how to manage them.
How we help
We gather white, red and pink samples in the grades that fit your use, then help you set the approved reference and colour limits in the spec. During loading we compare the goods against that reference. Begin with a free sourcing review.
