Quality & certificates — Tanbo Food Ingredients

Controlled from seeds to finished goods.

Our commitment to quality is a core business value in the production and delivery of high-quality, low-bacteria, compliant products that are free from any foreign material or added chemicals. Quality control starts straight on the farms, together with our agricultural partner who has more than 30 years' experience exporting to the EU and the UK.

How we protect quality

Safe, consistent, well packed.

Food safety & hygiene

All our staff are trained in HACCP food principles, because food safety and hygiene are our philosophy. Independent certifiers check our farms and factory regularly.

Product consistency

Our newest eco-friendly, closed stainless-steel machinery lets us meet every customer requirement for cut size and homogeneous colour, lot after lot.

Packaging & delivery

Packed in 20–25 kg polyethylene inside paper bags or cartons, with special packaging on request. Every bag carries its lot number for full traceability.

From the farm

Quality starts in the field.

With our agricultural partners we control every step before the onion reaches our factory.

Soil, water & compost analysis

Samples of soil, water and compost are taken and analysed before planting.

Approved fertilizers & pesticides

Each farm receives a specified list of acceptable fertilizers and pesticides, and these are the only products it may use.

Clear farm records

Clear and timely records are kept for all farms.

Random analysis before harvest

Analyses are conducted at random during the growing season and just before harvest.

Independent certifier checks

Our certifiers conduct random checks again to double-check everything and assure the quality.

Technology from the USA, Germany & Japan

Our brand-new facility was developed with experts from the USA, Germany and Japan. A substantial part of the machinery was customised to automate the whole process, so the product stays untouched by hands.
