WHAT IS ETHYLENE?WHAT IS ETHYLENE?The ripening of fruit and vegetables is started by Ethylene which is a natural, odorless,colorless and harmless gas - a plant hormone - that is emitted by fruits and vegetablesduring storage. Ethylene gas initiates and accelerates the ripening process and ultimatelycauses fresh produce to lose shelf life.

Wastage caused by Ethylene contamination during storage and transport is a signi�canteconomic issue for the post-harvest industry, marketers, retailers and commercial distributors. Fresh produce that is notorious for producing Ethylene includes apples, avocados, bananas,melons, peaches, pears, and tomatoes. When stored along with Ethylene sensitive producesuch as kiwifruit, broccoli, cabbage, cauli�ower, leafy greens, lettuce and others (refer to theproduce chart) Ethylene damage is triggered causing deterioration, loss of shelf-life andwastage. In addition to the natural emission of Ethylene gas by certain fresh produce, Ethylene gas canalso be emitted by engines. Propane, diesel, and gasoline powered engines all produceEthylene in amounts large enough to cause damage to Ethylene sensitive produce duringstorage. By removing Ethylene surrounding or in the vicinity of fresh produce and cut-�owers, shelf-life can be greatly extended and spoilage avoided. Everfresh Technologies Ltd. manufactures a range of products designed to absorb Ethylene. Our products utilise Potassium Permanganate (KMnO4) granules to absorb and removeEthylene. Potassium Permanganate media is widely used and proven in the horticultureindustry. It is an e�ective, simple and safe method of removing Ethylene even at very lowlevels. It is important to understand that Ethylene can have a negative e�ect on produce. Therefore,to keep stored produce fresher for longer, contact Everfresh Technologies Ltd, for an e�ective solution to your produce storage needs.

OUR DIFFERENCEOUR DIFFERENCE

THE COOL-CHAIN

We specialise in �ling-the-gaps in the cool-chain where Ethylene threatens the quality offresh produce on its journey to market.

We respond rapidly to every enquiry. We know the problems caused to fresh produce bythe presence of ethylene. We are local and customer service is our priority.

We customise solutions. We do not operate on either a one-size-�ts-all nor on ano�-the-shelf basis. We manufacture our products locally based on the scope, requirementor complexity of the project.

We maximise the e�ciency of Ethylene Control by calculating the likely Ethylene emissionduring the storage period using technical and scienti�c research data.

We employ people who understand the pressures of the horticulture industry.

HOW WE DO ITHOW WE DO ITPotassium Permanganate is the ‘media’ that is used to absorb Ethylene. This media is usedin a range of products that we manufacture for speci�c Ethylene Control situations in orderthat all potential Ethylene contamination gaps in the cool-chain can be controlled.

The media that we use is highly e�ective with a minimum 8% ratio of potassium permanganate.All Potassium Permanganate Active Media used within Everfresh Technologies Ltd �lters comesfrom source with ‘ISO 9001 Certi�ed (2008)’ Status ensuring compliance with its speci�edmanufacturing standard. We manufacture products for use in every possible situation and location where Ethylene mightthreaten the quality of produce. Such locations include:

Coolstores Shipping Containers Road Transporters Chillers Storage Rooms Trays, Cartons or Pallets Supermarket Shelving We can control Ethylene by selecting the most appropriate product in the Everfresh range to�t the Ethylene problem which has been identi�ed.

W E C O N T R O L E T H Y L E N E

The Active Ingredient in the entire Everfresh product range is known as Potassium Permanganate.

The Potassium is impregnated into a suitable carrier substrate with an internal surface areastructure far larger than the external surface would suggest. For example, 1gm of our Active Mediacan support an internal surface area of up to 1500m2!

The Active Media becomes saturated with Ethylene as the molecules pass through the media.As a natural consequence of this chemical reaction, the Active Media begins to turn from brightpurple in colour through to a dark brown when totally saturated. The Active Media is �rstlydiscoloured on the outside surface and becomes further discoloured internally as the outer layersbecome totally saturated with Ethylene.

To ensure continuous protection, it is essential that on a timely basis, a very small sample ofActive Media be taken from the �lters where possible and crushed to expose the inner surfaceto determine the internal colour properties. If the media still shows purple or reddish colours,the media is still active. If the media is pale to dark brown, the media is approaching or is atthe end of its active life.

For our customers that lease our machines, calculations are made using basic informationsupplied by our clients to enable us to project the life of the Active Media within the type andsize of machine in that installation. This enables us to actively service machines in a timelymanner as required or ship required Active Media to the customer as required.

BEST PRACTICE GUIDE TO MINIMISINGWASTAGE AND LOSS OF PROFITS

IN FRUIT & VEGETABLES

Ethylene gas is an odourless and colourless gas that is emitted by many fruits and vegetablesthrough a natural respiration process.

Ethylene gas accelerates the ripening process which causes fruits in storage to decay andvegetables & �owers to yellow and wilt.

Removing ethylene gas prevents loss of shelf-life and wastage.

NEW PRODUCT RELEASENEW PRODUCT RELEASE

Supermarket customers can now be o�ered a product that adds real value to the shoppingexperience.

A signi�cant percentage of the fruit and vegetables your customers purchase are wastedas a result of softening, wilting and decay. Consequently, customers tend to buy theseproducts on a cautious or limited basis rather than in bulk.

All fruits and vegetables give o� ethylene gas as they ripen. Much of the produce in the homerefrigerator is sensitive to the presence of even very low levels of ethylene gas. Many otherproduce types emit signi�cant levels of ethylene. The domestic refrigerator acts as anenclosed ‘trap’ for the ethylene gas given o� by fresh produce thereby quickening theripening process.

W E C O N T R O L E T H Y L E N E

beFresh neutralises ethylene gas in the home refrigerator – more than doubling theshelf life of the stored produce. beFresh keeps fresh produce crisper and fresher for severalweeks longer. It delays wilting and yellowing of leafy green vegetables and decreases decayand wastage in most fruit types.

Consumers can declare their refrigerator an ‘ethylene gas free zone’ by keeping a beFreshpack in the crisper draw of their fridge.

beFresh is designed and developed to compliment the fruit and vegetable section of thesupermarket utilising convenient plastic hook-over dispensers which do not compete withshelf-space nor obstruct pricing.

W E C O N T R O L E T H Y L E N E

beFresh is a simple to use product that e�ciently neutralises ethylene gas.

A small pack designed to be a�xed by suction-pad to the inside wall of the
