Here's Why Pears Rot Faster than Apples

Pears and apples seem similar enough. Compared to an orange or banana, pears and apples have a similar texture, taste kind of the same, have the same kind of skin and so on.

So why do pears rot so much faster? The biggest difference between the two, at first glance, is the shape. But that has nothing to do with it. It's all about the microscopic structure the fruits use to move oxygen from skin to core,
according to a report at the BBC.

Using a "giant X-ray machine able to resolve features down to and below a thousandth of a millimeter," researchers found pears use a smooth network of channels whereas apples have "irregular cavities" used to pass oxygen around. Apples have "much less water… to slow the penetration of gas," too.

Pound360 Archive

About Me

My photo
I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
