<p>Have you ever wondered what makes your cute, little carrot curl up when shred and left out for a while? Well, science has answered the question. It was not what they intended to answer. They simply quantified the process that makes carrots curl up if left uneaten for too long.</p>

<p>The research paper by Mechanical Engineering student Nguyen Vo-Bui was titled, "Modelling of longitudinally cut carrot curling induced by the vascular cylinder-cortex interference pressure", and was published in Royal Society Open Science.</p>

<p>Working in his kitchen, Nguyen characterised, analytically modelled, and verified the ageing of over 100 Lancashire Nantes carrot halves, and cut lengthways, using finite-element (FE) models normally used in structural engineering.</p>

<h2><strong>Why a carrot curls up?</strong></h2>

<p>The research team concluded that residual stresses and dehydration were the two key factors behind the curling behavior.&nbsp;</p>

<p>The starchy outer layer of the carrot (the cortex) is stiffer than the soft central vein. When cut lengthwise, the two carrot halves curl because the difference in stress becomes unbalanced. Dehydration leads to further loss of stiffness, further driving the curling effect.</p>

<p>The study gives food producers a new mathematical tool that could be applied to the design of packaging and food handling processes, potentially reducing food waste.</p>
