Title: These Genius Fruit Labels Tell Us Why 'Chemical-Free' Is a Useless Term

Sci-Alert...

The idea that there is a difference between "natural" chemicals - like those in fruits and vegetables - and the synthetic version of those chemicals produced in a laboratory is a common misconception.

Marketers often feed off consumer concerns that "human-made" chemicals are bad. But the fact is that all foods, and everything around us, are made up of chemicals, whether they occur in nature or are made in a lab.

Australian chemistry teacher James Kennedy wanted to dispel the myth that chemicals are bad for us. He created an ingredient list for natural products, like the banana above, to show that there are many chemicals in our food's natural flavours and colours.

And some of them have long, scary-sounding names, too.

"There's a tendency for advertisers to use the words 'pure' and 'simple' to describe 'natural' products when they couldn't be more wrong," Kennedy writes on his blog.

"As a Chemistry teacher, I want to erode the fear that many people have of 'chemicals' and demonstrate that nature evolves compounds, mechanisms and structures far more complicated and unpredictable than anything we can produce in the lab."

You can see more "all-natural" posters below, and head over to Kennedy's blog to check out all of his great infographics, like a table of esters and their smells.

'Chemical-Free' Is a Useless Term

Ethylene gas is used commercially to ripen tomatoes, bananas, pears, and a few other fruits postharvest. Ethylene can be explosive if it reaches high concentrations, so it has to be used cautiously. Several commercial liquid products release ethylene (ethephon, trade name Ethrel). These are only used preharvest.

One time we had 4 pallets of green tomatoes. They were so green the receiver didn't want them. So we called the shipper. They said, "Just tell them to give the tomatoes a little more gas."

That turns them pink, but they are still hard as a rock. ROTFLOL

In the case of vine-ripe tomatoes, something else used to preserve them?

Re: aluminum recycling, are Al pie plates and the bake-chicken-in-a-dish containers suitable for recycling or would they tend to vaporize when smelted into ingots?
