Tesco has started selling green lemons after relaxing its quality specifications in an attempt to avoid shortages in its UK stores and reduce food waste.
Although the skins are slightly green, the fruit is as zesty and robust as lemons that have turned completely yellow, while the flesh inside is ripe and edible.
The UK’s largest retailer has lifted its colour requirements for lemons partly to help offset domestic food waste by adding up to an extra two days’ shelf life to the fruit as it ripens.
There has also been a shortage of yellow lemons caused by poor growing conditions in Spain, which supplies the UK with the bulk of the fruit until the end of spring.
South Africa’s lemon season traditionally begins in late June and it takes over as the UK’s main supplier. However, Tesco will take the greener South African lemons earlier than usual to avoid gaps in its supply.
“These greener lemons that we now have on sale are already mature and perfect tasting inside but need longer for the skin to turn yellow,” said Tesco’s citrus fruit buyer Savia Weidinger-Reich.
“With the South African crop, that happens towards the end of June as evenings cool, which helps the fruit to colour. The move not only means that shoppers will again be easily able to buy a fruit that is growing in popularity, but they will gain extra freshness.”
Tesco said lemon sales had risen by nearly 10% over the last year as more people used them in recipes and juicing.
The greener lemons – the same price as regular yellow ones – are unlikely to be confused with limes as they have the more distinctive, elongated shape of lemons. Last year, Tesco started selling green satsumas and clementines to reduce food waste.
The retailer says it is committed to reducing food waste throughout its supply chain and works with farmers and suppliers to adjust crop specifications.
