Spices for food manufacturers are bought on specification: microbiology, consistency from lot to lot and particle size matter more than the headline grade. Dehydrated onion for seasoning and onion powder for snack seasoning have to flow, blend and dissolve predictably. Garlic powder for the food industry and spices for meat processing add the need for low microbial counts and a steady flavour strength.
Restaurants, ethnic grocery stores and spice grinders in Europe buy differently, and the sections below cover each.
Food manufacturers: what to put in the spec
An industrial buyer wants the same product in every lot. Write down these points, and test each lot against them:
- Particle size or mesh, with a tolerance, because it controls blending, dusting and caking. A template is in how to write a specification for dehydrated onion powder.
- Moisture, because it drives caking and shelf life.
- Microbiology: total plate count, yeast and mould, coliforms and Salmonella, as described in the microbiological limits that apply to spice powders in the EU and US.
- Colour and flavour strength, so the seasoning looks and tastes the same each time.
- Foreign matter, metal detection and allergen statements.
Seasoning, snacks and meat processing
Snack seasoning needs fine, free-flowing onion and garlic powder that sticks to the product and does not clump in the drum. Ask about anti-caking agents, since they will appear on your label.
Meat processors use spice in cures, rubs and sausage blends. They care about microbial load, because spice goes into a product that may not get a kill step, and about steady pungency. Steam-sterilised spice is the usual specification, which is explained in whether spice powders need steam sterilisation. Tell the supplier the end use up front, because a lot made for a cooked sauce is not always right for a raw rub.
Particle size deserves a separate check for seasoning. A powder that is too fine dusts and absorbs moisture, and one that is too coarse separates from the other ingredients in a blend. Agree a mesh range with the supplier and test it on each lot.
Restaurants, grocers and European grinders
Restaurant suppliers and ethnic grocery stores buy smaller volumes across many lines. Their problem is usually quantity, not grade. Container sizes are large for a single spice, so mixing lines is the practical answer. Read whether you can buy less than a full container and whether you can mix several spice powders in one container.
A European spice grinder buys whole spice and grinds locally. Their concerns are cleaning level, residue limits, volatile oil and the sterilisation step they carry out themselves. They should ask for whole spice with a certificate for each lot.
Why plant standards matter more than price
A manufacturer's lowest risk is a supplier that controls its own process. Look for documented HACCP, a metal detector, sieving and traceable lot codes, and verify them on site. A factory audit tells you what really happens, as set out in what a factory audit report should contain.
Cost differences between suppliers come from the raw material grade, the treatment, the testing and the packaging. A quote only means something against a written specification.
