Paprika in FF culture media?

I've heard some references in posts on this board about adding paprika to FF culture media. I googled up some guy's experiment where he got better longevity in his cultures (if I interpret his experiment right) by supplementing with paprika http://www.cryonet.org/cgi-bin/dsp.cgi?msg=8980.

Has anyone had any experience with this? Also, is the paprika just for the flies, or is it for the frogs?
