Alcohol sugars are alcohol forms of glucose, fructose, and another single sugar, xylose. The alcohol form of glucose is called SORBITOL or GLUCITOL, the alcohol form of fructose is MANNITOL, and the alcohol form of mannitol is called XYLITOL. Sorbitol (glucitol) is changed into fructose when it reaches the liver.
maltose = 40% as sweet as glucose
lactose = 20% as sweet as glucose
glucose = 70% as sweet as glucose
fructose = 110-170 as sweet as glucose
sorbitol = 70% as sweet as glucose
mannitol = 70% as sweet as glucose
xylitol = 90% as sweet as glucose
glucose syrup = 30-60% as sweet as glucose high-fructose corn syrup = 100-150% as sweet as glucose By the way, you should know that "high fructose corn syrup" is mostly glucose, up to 75-80% glucose.
One more is Maltitol.
Maltitol is a member of a family of bulk sweeteners known as polyols or sugar alcohols. It has a pleasant sweet taste--remarkably similar to sucrose. Maltitol is about 90% as sweet as sugar, non-cariogenic, and significantly reduced in calories. Maltitol is especially useful in the production of sweets, including sugarless hard candies, chewing gum, chocolates,* baked goods and ice cream."
Maltitol has a nasty side effect, if you get too much at one time, it will cause severe diarrhea. I made the mistake of buying some 'Sugar Free' chocolate which was made with Maltitol. I ate 4 pieces and was in the bathroom for 2 days. Be careful with this particular alcohol sugar.
