[edit] long-lasting apple?
Why do Granny Smith apples take longer to brown than other types of apples?
- The browning of apples (once exposed to air) is the result of enzymatic oxidation (enzyme mediated oxidation). The distinctly sour flavour associated with the granny smith variety results from its innate acidity, presumably caused by an higher concentration (in reference to other varieties) of ascorbic acid (vitamin C). Much like any other enzymes those responsible for mediating the browning of apples are denatured in environments of high acidity, thus the high acidity (approx. pH. 3.25) of the granny smith variety is what affords them their longevity (at least in terms of oxidation reactions) by denaturing the enzyme (a chemical mediator) and thus hindering/slowing the oxidation reaction. 84.92.185.112 07:08, 23 March 2007 (UTC)Anubeon

[edit] green apples?
I'm a little confused. Are Granny Smith apples the only type of green apple? The fact that "green apple" redirects here suggests that, but then the statement "Granny Smith apples tend to have a harder texture than other green apples" doesn't make much sense. -VJ 21:15, 19 September 2006 (UTC)
- Rhode Island Greening is a fairly common pie and sauce apple in the US, but I think it would be every bit as hard as a Granny Smith. I've never had two equally ripe ones together, though, to compare. Pollinator 23:50, 19 September 2006 (UTC)

- So there are other types of green apples, besides Granny Smith apples? -VJ 03:31, 21 September 2006 (UTC)
- Fairly common is relative. R.I. Greening account for less than one percent of U.S. apple production (and have fallen out of the top 15 varieties produced in the U.S.) In 1978, before Granny Smith became popular, R.I. Greening was as high as 8th with 2.3% of the total harvest. Granny Smith by comparision has been as high as third most popular (now 4th) and about 7% of the total crop.

[edit] Second picture
I noticed the second picture is a .png file & thus much bigger than a .jpg (for that sort of picture anyway); I'm new to this sort of thing - should I chat to the picture poster, reformat it myself or do something else entirely? Rockcake 07:58, 7 December 2006 (UTC)
