Scientists consider they could have discovered the reply to why cut carrots curl if left uneaten for too lengthy.

Researchers from the University of Bath have found that when this root veg is cut lengthwise and left uncovered to air for a very long time, it may begin to lose moisture.

This causes the outer layer of the carrot – referred to as the cortex – to dry out sooner than the centre, making it bend outwards.

The staff mentioned that dealing with carrots in a chilly, moist, and hermetic atmosphere can “protect their natural properties and increase their edible life span”.

Dr Elise Pegg, a senior lecturer in the University of Bath’s Department of Mechanical Engineering – who oversaw the research, mentioned: “We have mathematically represented the curl of a cut carrot over time, and showed the factors that contribute to curling.

“Our motivation was to look for ways to improve the sustainability of carrot processing and make them as long-lasting as possible.”

She mentioned the staff’s work, printed in the journal Royal Society Open Science, offers meals producers a brand new device that might probably assist them scale back not simply carrot wastage however different root veg as effectively.

The analysis was carried out throughout lockdown by Nguyen Vo-Bui, a mechanical engineering scholar at the University of Bath.

He used mathematical fashions from structural engineering to analyse greater than 100 Lancashire Nantes carrot halves.

Over the course of every week, the researchers discovered that the carrot halves steadily stored curling outwards – and the common radius of every carrot’s curvature dropped from 1.61m to 1.1m.

The weight of the carrots additionally fell by 22%, they mentioned.

Mr Nguyen added: “This was interesting research – to apply mechanical principles to vegetables was surprising and fun.

“One of the big challenges was to devise an experiment that could be done in a lockdown setting, without access to normal labs and equipment.”

The researchers mentioned that round 25-30 per cent of carrots are sometimes wasted earlier than being processed or packaged due to deformities, mechanical harm or contaminated sections.

Dr Pegg mentioned: “We have produced a methodology that a food producer could use to change their processes, reducing food waste and making packaging and transportation more efficient.”

Mr Nguyen mentioned as soon as the experiments have been completed, the carrots have been then used to make dishes comparable to carrot cake, the Indian carrot dessert Gajar Ka Halwa in addition to carrot pesto.
