Major supermarket unveils tech that will tell you whether your avocado is ripe

It can tell whether the fruit is ready for smashing or better used sliced

Shoppers will soon be able to access a new way to check if their store-bought avocados are ripe as Tesco trials a new high-tech system.

Available in five stores from this week, the machines can read the fruit's internal state.

Holding an avocado in the machine’s scanner, it will tell customers either if their avocado is overipe, and ready to be smashed, or if it is less ripe and instead better for slicing or waiting to ripen.

Named the One Third Avocado Scanner after the Dutch company that invented it, the technology measures ripeness in a few seconds, aiming to help consumers pick the perfect fruit.

The company explains that the technology works by scanning through the avocado using light.

The aim of the service is to avoid customers needing to pinch or squeeze the avocado, potentially ruining its flesh and leading to food waste.

Tesco avocado buyer Lisa Lawrence said: “The scanner will enable shoppers to choose the avocado that is right for them and which therefore can help them plan their usage and desired shelf life, thereby cutting down on waste.

“Smashed avocado on sourdough continues to be one of the trendiest snacks at the moment, garnering millions of views on social media sites for recipe ideas, so we think, for that reason, the scanner will be really popular with shoppers.”

The Tesco stores trialling the scanner will be:

• Cheshunt Extra in Hertfordshire
• Colchester Superstore in Essex
• Stratford-upon-Avon Superstore in Warwickshire
• Wokingham Superstore in Berkshire
• Salisbury Extra in Wiltshire.

Tesco said avocados have never been more popular and in the last year it sold nearly 15 million more avocados than it did in the previous 52 weeks.

The supermarket giant has worked with global avocado supplier Westfalia Fruit, based in Spalding, Lincolnshire, on the project.

Westfalia Fruit’s commercial manager Emma Howes said the scanner is “just one of many initiatives we’ve worked on over the past year”.

She said other initiatives included trialling lasered avocados which removes the plastic label from Tesco’s loose avocado lines, and rolling out cardboard and paper packaging across all Tesco’s avocado pre-packed lines.

She said this helped in “saving 20 million pieces of plastic a year”.
