OW1 is versatile and easy to use. OW1 can be adapted for use in any type of washing system. There is no foam or mess and no mixing is required.

It can be used on a wide variety of produce, from unpeeled potatoes, carrots, parsnips, swede and radish to grapes, apples, oranges and tomatoes. It will also perform extremely well on peeled onions and carrots, cabbage and leafy salads. OW1 is a green tinted liquid available in 25Kg drums, 250Kg Barrels or 1250Kg IBCs.

Developed in 1999, OW1 has proven to be a first class product, an effective and safe decontaminate for fresh produce, used by many processors in the UK and Europe, including supermarket suppliers.

Does OW1 have to be declared on packaging?
There is no labelling requirement for OW1 on packaging. OW1 is HYGROSCOPIC which means it works immediately on contact with the product and then naturally dissipates soon after. OW1 is not an ingredient or a preservative, it is a processing aid and presents no technological effect on the produce after the initial contact. There is no residue left on the treated produce (Independent laboratory tests are available to show this).

Recommended concentration of OW1 and how to measure the concentration of the treatment solution.
The concentration is dependant on the type of produce to be treated and includes other variables such as how the produce is washed and the extent the microbe loading is to be reduced by etc., usually between 0.25% - 1.0% concentration is recommended. The concentration can be measured manually with a pH meter or an automatic system can be used, which monitors and doses accordingly.

Is OW1 economical to use?
If used at 0.5%, one 25Kg container would make 5000 litres of highly effective washing solution and because it is not absorbed by organic matter (like chlorine based products) the concentration will not deplete, this means more produce throughput.

How effective is OW1?
OW1 is extremely effective at decontamination. It’s unique formulation will also help enhance the shelf life. Independent laboratory tests show exactly how effective it is against some other products on the market.

What does OW1 do and how does it work?
It radically reduces bacteria, including pathogens, yeasts and moulds on the surface of fresh vegetables, salads and fruits. The finely tuned ingredients form an environment that make it almost impossible for bacteria to survive in. It inhibits reproduction, respiration and absorption of sugars and it also alters cell membranes. This makes OW1 exceptionally efficient at killing both Gram Positive and Gram Negative Bacteria.

What is OW1 and is it safe and legal?
OW1 is a unique blend of organic acids, all of which are passed by The Soil Association, The Food Standards Agency and all other relevant UK and European bodies for use as a decontaminate for fresh produce.

Which produce can be washed with OW1?
OW1 can be used on all produce, particularly ready washed salads and other high risk produce which is not cooked before being consumed. It will offer significant advantages to shelf life if used in barrel washers or hydro-coolers for washing produce such as radish, potatoes, parsnips and carrots.

How is OW1 used?
OW1 should be mixed with fresh cold water and the products to be treated should be submersed and at least lightly agitated. It can be used in small tanks for batch washing or it can be used in mechanical systems such as flume washers, agitation tanks, barrel washers and hydro-coolers.

Does OW1 have any adverse reactions on the treated produce?
OW1 leaves no taste or odour and does not effect the colour or texture in anyway.
