NP Rank:
Apples Beat Pears Due to Better Circulation
Thanks to science, we now know why apples stay fresh longer than pears.
It is all to do with how oxygen is able to find its way to the centre of the fruit after it has been picked.
Belgian researchers used one of the world's most powerful X-ray machines to image the tiny pores and channels that carry air through the two foods.
Pieter Verboven's team was able to show how the structures in pears meant they got "out of breath" quicker than apples - key information for growers.
The results of the study will improve the models used to determine optimal storage conditions.
There is a clear economic driver to minimise wastage in the fruit industry; and supermarket shoppers certainly do not want to cut into the flesh to find a brown, mushy mess.
Year on year, very practical experiments are run to see how different crop varieties cope under a range of shelf conditions; but science is also trying to improve its understanding of the biochemical and physical mechanisms that underpin decay.
Vasculature of oxygen. That's why your picnic basket is full of wasp-friendly mush.

Interesting...I'm going to impress people with this (or weird them out, probably) the next time I enjoy a social piece of fruit.

jordan, I like this story. It's good stuff.
We could mess this up with some GMO treatment! No I rather not though!

I am famous in my household for making apple and pear pie, it never lasts for more than one meal so it is a bit hard to determine which stays freshest the longest!!

surrender, you pear! you are surrounded by apples!

Unfortunately is to early for Polish apples and pears - fruits from photo are imported from somewhere in Europe.

I set up the picture with two random pieces of fruit from my fruit bowl. I was trying to set them up to look like the pieces of fruit were portraying an emotion or action. This picture is titled "Cower" because it looks like the apple is cowering from the huge claw of the pear.

This is a beautifully presented fruit plate from a Japanese/Korean restaurant in Kostanai, Kazakhstan. All this for about $18.00 if you convert to US dollars.

Interesting research. I hope this won't encourage even further delays between picking and eating commercially grown fruit! I remember the wonderful taste of freshly picked golden delicious apples from our garden, brimming with vitality! This picture you have chosen of mine, was taken while we were on holiday in Wellington, New Zealand and staying in accommodation which had wonderful fruit growing in their relatively small garden. They had chosen to grow their fruit espalier style and used small tree varieties to suit their small garden area. There are some lovely shots of pears also on my flickr site, which were also growing in this garden.

This comment is related to my photograph posted at the top of this page.
The fact that i was sick with influenza the day i took this photograph, sparked the thought in my head about an apple a day keeps the doctor away. Just another reason Apples beat pears ;)

I like apples a lot better than pears for the taste and you can make many more recipes from apples!!
Thank you for selecting my photo !!
Great story, Jordon!!

The fruit in South East Asia is quite something, so is the way they display it. I would have to say that Asian Apple Pears are pretty wonderful, but only if you have them in Asia. The imported ones are quite tasteless. I wonder what science would have to say about Apple Pears. The best of both worlds perhaps? Also in my picture are custard apples...now those are a fruit of their own standard, something I had never quite experienced. Again, you have to try it in Asia, not imported varieties.

While apples may win the beauty contest, and are available year-round due to cold storage, pears are much tastier and appealing perhaps because they are so fragile and transitory.

Photo taken in the best island of Greece, Santorini. There is a fruit stand in Fira that has all types of fruits including Pears and Apples.

Pears are great, but they can be messy to eat, it is interesting to hear there is a scientific reason for their optimum eating time being about 3 hours! My photo was taken in my kitchen using a chopping board as a backdrop. The pears were just about to 'go over' so the apple reigned supreme.

i think the points are valide, but at the end of the day apples are easier to eat, as to pears - these are some of the main reasons why they are so popular and may last longer... I eat lots of apples and pears, but thats due to weight watchers points system, and they are easy to eat. however, they are in my list of least favorite fruit. i would have melon, banana or peach any day.

Someone thought my photo will complement the story on apple and pear. Plums are also good for you.

We grow a number of varieties of pears and apples in our family orchards here in Hood River, Oregon, which is the nation's leading producer of winter pears!
We combine the two fruits with a variety of other gourmet delicacies and ship them throughout the nation in handcrafted baskets and watercolor-adorned boxes.
However, despite scientific research on apples versus pears, we will always side with the pear! Especially the succulent and ridiculously juicy Webster Comice. :)
