The science of wash and seal

An oxidative wash that breaks down surface pesticide residues, followed by a thin, food-grade edible coating that slows moisture loss — run as six steps on a single line.

The process

Six steps, one continuous line

Steps 1–3 clean the surface. Steps 4–6 protect it.

Step 1

Receiving & pre-rinse

Produce is received, sorted and pre-rinsed to remove soil, field dust and loose debris before treatment.

Step 2

Oxidative wash

Vegetables pass through an aqueous oxidative wash that degrades pesticide residues on the surface and reduces the microbial load.

Step 3

Potable rinse

A potable-water rinse carries away the oxidant and the breakdown products, leaving a clean surface.

Step 4

Edible coating dip

Cleaned vegetables are dipped in a four-component, food-grade edible coating that forms a thin protective film.

Step 5

Forced-air drying

Forced air sets the film evenly across the surface so the coating performs consistently.

Step 6

Pack & store

Treated produce is packed in ventilated containers for cool storage and distribution.

Stage 1 · The cleaning engine

Oxidative wash

OZOVEG uses oxidants of the kind already used worldwide for water treatment. Dissolved in water, they attack the chemical bonds that hold many pesticide molecules together — for example, the sulphur–phosphorus bonds of organophosphates and the double bonds found in many other pesticide classes.

Breaking these bonds converts the parent compound into smaller, more polar and generally less toxic products that rinse away more easily.

  • Degrades surface pesticide residues
  • Reduces spoilage and pathogenic microbes on the surface
  • Keeps the wash water itself from becoming a source of cross-contamination
  • Ozone decays back to oxygen and leaves no persistent residue

Bond-breaking chemistry

Oxidants target unstable bonds in pesticide molecules, turning them into simpler, water-soluble fragments.

Controlled wash water

Oxidative wash water stays sanitary across the batch instead of spreading spoilage from one vegetable to the next.

Stage 2 · The preservation technology

A four-component edible coating

Once the surface is clean and dry, a thin layer is applied that the consumer can eat without noticing. Each food-grade component has a defined role — together they preserve texture, colour and taste without synthetic preservatives.

Film former

A natural polysaccharide from the cluster bean forms a semi-permeable barrier that slows water loss and moderates gas exchange, so the vegetable respires more slowly.

Firmness keeper

An organic lactate strengthens plant cell walls and helps hold firmness and crunch.

Surface guard

An organic acid lowers surface pH, discourages microbial growth and slows enzymatic browning.

Moisture holder

A natural osmolyte found in beetroot helps tissues retain water and tolerate stress during storage.

Why the sequence matters

Never seal in what should be washed out

Coating a vegetable that still carries residue or a high microbial load would simply seal those in. By placing the oxidative wash and potable rinse first, OZOVEG ensures that the protective layer is laid over a surface that has already been cleaned.

Validated under defined conditions. Product performance and pesticide reduction are validated under defined processing conditions for each crop and line.
