Where we sit in the chain

From the seed a farmer buys to the jar on somebody's shelf there are seven links. We are the fourth — the one that decides whether everything upstream was worth it.
  1. 01

    Farm supplier

    Seed, fertiliser and inputs reach the grower. The quality of what comes out of the ground is set here, long before anything is treated.

  2. 02

    Farmer

    The crop is grown and brought to maturity. Temong works with growers to make sure the harvest arrives in a condition worth protecting.

  3. 03

    Harvest and transport

    Product is lifted and moved to the plant. Time and handling in this window drive most of the microbial load we later remove.

  4. 04

    SterilisationThis is our step

    Our step. Saturated steam removes bacteria, moulds and pathogens while flavour, colour and texture are held intact. No chemicals, no radiation.

  5. 05

    Primary aggregator

    Treated product moves to the wholesaler or retailer, consolidated and ready to enter the formal supply chain.

  6. 06

    Distributor

    Product is distributed onward to the businesses and outlets that will put it in front of a buyer.

  7. 07

    Consumer

    The crop reaches the table with its character intact and its microbial risk removed. That is what the whole chain is for.

What we treat

Herbs and spices, for suppliers, distributors and food manufacturers. Send us the details of your product and we will tell you whether the process fits it.
  • Herbs

    Treated without chemicals or radiation, so the flavour, colour and texture of the leaf come through the cycle intact.

  • Spices

    Bacteria, moulds and pathogens eliminated while the true taste, aroma and appearance are maintained.

The things people ask first

If yours is not here, ask it directly — we would rather answer than have you guess.
  • Saturated steam is applied to the product under controlled conditions. The heat and moisture destroy bacteria, moulds and pathogens on the surface of the crop. The cycle is tuned so that the product is treated and then dried back without cooking it — which is what separates sterilisation from roasting.
