Greenvale's new packaging for its Lady Balfour organic potatoes has increased shelf life, decreased wastage and reduced complaints about greening by over 50 per cent, the company has revealed.
Lady Balfour is one of the UK's top-selling organic potato varieties, accounting for almost 10 per cent of all organic potato sales in the UK, and has been encompassed in the company’s new biodegradable modified atmosphere packaging (MAP).
Charlotte Manwaring, key account manager at Greenvale's Market Drayton site, said: "We originally changed over to a biodegradable film for packaging Lady Balfour some years ago. Although it was a successful switch, the one area of customer complaint was greening. We developed the new MAP packaging to overcome this greening issue."
Greening can be caused by exposure to too much light or if the potatoes have a high respiration rate. MAP can reduce the respiration rate by regulating the relative proportions of carbon dioxide and oxygen in the pack and Greenvale achieves this by manipulating the number and size of the perforations in the film.
Having developed the new MAP biodegradable film, Greenvale instigated shelf-life trials to see if it reduced the greening levels in the Lady Balfour potatoes.
Manwaring added: "The trials showed that not only were we significantly reducing greening in the potatoes, with customer complaints cut by over 50 per cent, but that we could also actually increase the shelf life of the product, potentially reducing waste.”
