Today's factoid: Fructose melts at 104°C (219°F). Dextrose and glucose melt at 146°C (295°F). Sucrose melts at 186°C (367°F).

The reason I'm interested in this is because I'm trying to figure out if the slow-cooking process I use for beef ribs will, in fact, allow me to use add barbecue sauce during the cooking phase. The sweetener in most bottled barbecue sauces is high-fructose corn syrup (a mixture of fructose and glucose). So presumably, if the cooking temperature reaches the melting point of fructose, you'll start to get carmelization in the sauce, and that will destroy the flavor.

Cooking at 200°F should be low enough to avoid that. But I think I may have to experiment with it before trying it out on my rib-loving friends.
