Channel 4 Food Unwrapped viewers say they feel 'physically sick' after finding out what the wax which coats most lemons is made from. Millions of the people who buy lemons every day will be familiar with the wax layer you'll find on top.
As such, Channel 4 presenters Kate Quilton and Matt Tebbutt wanted to find out exactly why our lemons are so waxy. The Food Unwrapped presenting duo headed across the globe in their quest for information.
On their travels, it became apparent to the pair that the wax around lemons contains shellac. This was surprising to beauty-lovers, who best know shellac as a nail polish.

To learn what goes into making shellac, Kate headed out to Thailand, where host Tomas took her out into the jungle for a proper demonstration. Kate was left stunned to learn that the ingredient was found in the trees, after Tomas cut off a branch covered in nests of insects known as lac beetles.
These beetles attach themselves to the tree for the duration of their six-month life cycle, sucking up the sap, absorbing it, and secreting it until they quite literally feast to death. At the same time, each female will lay approximately 1,000 eggs before their short time is up. Explaining the process to an amazed Kate, Tomas said: "The shining product we make is from pee or waste from the beetles".
Viewers were left feeling 'physically sick' by this revelation, particularly given that Kate had already sampled the shellac for herself, remarking upon its distinct taste, reports the Mirror. One person shuddered: "Beetle waste and pee that's what wax lemons we buy... yuck."
Another declared: "I knew that the wax on lemons is not vegetarian! Will never buy waxed again!" As previously reported by Madehow.com: "The sap is chemically altered in the lac bug's body and is then exuded onto the tree branch. On contact with the air, the excretion forms a hard shell-like covering over the entire swarm.
"This covering forms a crust over the twig and insects. As the female lac bug is exuding the ingested sap, she is preparing to die and is providing a fluid in which her eggs will mature under protection.
"The males' role is to fertilise the female, and it is after fertilisation that the females' lac output is vastly increased. The adult males and females become inactive, and the young start to break through the crust and swarm out."
