Science Buddies: "Ask an Expert"

What kinds of apples brown at a quicker rate than others? Can you please give me some websites to go on mary and other people? thank you.

Can you give any reason why one apple would brown faster than another?

Hi pete,

You should take a look at some of the links from the previous reply I posted. One of the articles says - "Granny Smith apples do not brown as quickly as some other cultivars because they generally have a little more acid which will limit the PPO enzyme activity." So maybe you should look up how acidic different types of apples are. Here is a link to a table of apple varieties:

You should be able to determine which varieties are more or less acidic and get an idea of which ones would brown faster or slower.

You could also do a google search yourself using the terms apple and acid. It is important to get all your background information together prior to designing your experiment.

I hope this helps.

Mary
