Fruits, vegetables and flowers naturally produce ethylene (a gas and plant hormone) as it helps them to ripen – but unless it is removed at the right time it builds up in storage and transport and forces them to overripen, wilt and decay.

EMCO’s ethylene scavenger sachets can be used in packaged or bulk environments to prevent this build-up, which substantially extends shelf life. The sachets have disinfecting properties which actively reduce spore (bacterial and fungal) reduction in air.

The sachets help to eliminate decay, mould, discoloration, wilting, softening, scald, loss of crunch and other negative effects. They can be used both during postharvest handling where they slow down the ripening process and also during domestic and international shipments travelling via ocean, truck, rail or air. This is additionally important as ethylene is actually also produced by both mechanical damage and in the exhaust fumes of internal combustion engines.

EMCO’s scavenging sachets also improve the texture and nutritional quality of produce while reducing unpleasant odours emitted from over-ripening, keeping things fresh, succulent and appealing for far longer.

Ethylene levels of just 0.1 ppm are commonly considered as the threshold for ethylene action on plants, but some plants are especially sensitive including apples, pears, avocados, kiwifruit, persimmons and carnations.

Whereas bananas remain “green” when ethylene concentrations are below 0.1-0.2 ppm, exposures of just 0.01-0.08 ppm can trigger carnation blooms.

EMCO has nearly 25 years’ experience in active packaging systems and positions itself at the cutting technological edge in this area.
