Many fruits and vegetables shrink when dried, their shape also changes. But a mechanical engineer was attracted by the special behavior of carrots. It is seen that carrots do not remain straight after drying. But why does this happen? If you find this question very trivial, then you will have to read this complete news.
If you have left long carrots for too long, they automatically become crooked when they dry. The answer to this simple question has been given by mechanical engineering student Nguye No Biu in his research paper titled “Modelling of longitudinally cut carrot curling induced by the vascular cylinder- cortex interference pressure” published in Royal Society Open Science.
Working in the kitchen, Nguyen cut 100 Lancashire Nantes carrots lengthwise and analyzed their aging process using finite element models. These models are especially used in structural engineering.

Researchers found that residual stresses and dehydration or lack of water are the two main causes of carrot curling. The outer part of the carrot, called the cortex, is harder than the central vein in the middle. Dividing the carrot directly into two parts creates an imbalance in the internal pressures.
Apart from this, lack of water further reduces the hardness of carrots. This makes the turning effect more effective. This seemingly useless research has given food producers a new mathematical tool. It can be used in the design of food storage and packaging. This can also help prevent food from spoiling and becoming waste.
Dr Else Pegg, senior lecturer in mechanical engineering at the University of Bath and one of the authors of the paper, said in a statement that they had mathematically demonstrated the bending of carrots over time after being cut, and also described which Factors that contribute to hair loss.

Researchers say that they were looking for ways to improve the processing of carrots, so that carrots can be preserved for a long time. He also claimed that he has found a way by which food producers can stop it from spoiling by changing their methods.
