A real dehydrated onion manufacturer in India dries and mills the onion in its own plant. A re-packer buys finished product from other plants and bags it under its own name. Both sell dehydrated garlic powder too, so the first job when you search for a dehydrated garlic powder manufacturer is to find out which kind you are dealing with.
A re-packer can deliver acceptable product, but it cannot control the drying, the sieving or the sanitation, so it cannot fix a quality problem at source.
Signs of a real plant
A real plant can show you the whole line: the washing and peeling area, the slicing, the dryers, the milling and sieving, the metal detector and the packing. It keeps production records by batch and can tell you the day your lot was dried.
Ask for a video walk-through of the line, with the person filming moving from raw onions to finished bags in one shot. Then ask for the plant address, and have it visited.
Signs of a re-packer
No single sign proves a re-packer, but several together should make you cautious. Our guide to telling a trader from a manufacturer has more questions. These are the signs to watch for.
- The supplier cannot name the dryer type or the drying temperature.
- Batch records cover only packing, not drying or milling.
- Several different lots in one week come from unnamed sources.
- The address given is an office, not a plant, and a visit is always postponed.
What a good plant controls
Dehydrated onion and garlic powder can carry bacteria such as salmonella if washing, drying or storage is poor. A good plant controls its water supply, dries at a controlled temperature, cools before packing, and sieves and metal-detects the product. Many also use steam sterilisation, so ask whether that is done and how it affects flavour.
Ask also what the plant does with sweepings and off-grade powder. Product that fails the sieve can be reground and blended back, which changes the particle size and the colour of your lot. A good plant keeps off-grade material apart and can show you where.
Moisture control after drying matters because the powder takes up water from the air within minutes. Packing in a controlled area with liners prevents caking in transit.
Certifications and what they cover
Plants hold food safety certifications such as HACCP, ISO 22000 or FSSC 22000, and sometimes BRCGS. Read which certifications a dehydration plant should have to see what each means and which your customers expect. Check each certificate against the issuing body and confirm that the scope includes dehydrated onion or garlic and the site you are buying from.
A certificate is not a substitute for testing. Have your own lot sample tested, and use our audit checklist for Mahuva dehydration plants when you visit.
Next step
We find and audit dehydration plants, test lots and supervise loading, so you know the product comes from the plant you approved. We do not publish prices, as they depend on form, mesh and crop. To discuss your specification, book a free sourcing review.
