UK shoppers are at their wit's end as 'ripen at home' fruit and vegetables continue to fall short of expectations. The trend has left many questioning the merits of this modern supermarket practice, which prioritises shelf life over natural ripening.
The shift towards controlled atmosphere storage – a system pioneered by countries such as France in the 1970s – has been instrumental in making year-round produce available. Techniques like low temperatures, high carbon dioxide levels and reduced oxygen allow fruits to be picked unripe and stored for months before release, often with the aid of ethylene gas to stimulate ripening.
While these methods have cut waste within the supply chain and boosted availability, critics argue that they come at a cost. Fruits stored this way may lack the depth of flavour and natural ripening qualities found in produce left to mature on the plant. As a result, supermarkets rely heavily on varieties bred for durability rather than optimal taste.
The pressure to maintain 52-week availability has led to long-term deals with international suppliers, squeezing out space for locally sourced, seasonal produce that might offer a more traditional ripening experience and superior flavour.
