Dear Bionetters:
I have the following question:  
In the USA, boiled potatoes usually change from yellowish to grayish or 
brownish colors.  In Germany, most of the potatoes retain their nice 
yellow color even until the next day.  What is the reason for this?  Does 
this depend on the potato variety, cultivation (i.e., fertilization, kind 
of soil), and/or climate?
Thanks in advance,
Dietmar Tietz
