You realize yall made me study!
Manufactured from corn, dextrose is a form of glucose, a monosaccharide, or "simple" sugar.
So Sucrose (we call refined sugar) is made up of fruitcose 50% and glucose 50% although the percentage can variy. Of the fruitcose and glucose, the glucose is the good stuff while the fruitcose is frowned upon. The glucose raises the blood sugar levels and super charges the absorption into the muscles to feed them lean energy. Brown rice syrup being the best known source. Its why rice goes bad so fast, because the starch breaks down into glucose which is the most easily digestible simple sugar. Many recipes replace sucrose (sugar) with dextrose which is pure glucose powder.
Its been a long time since school!
I am thinking I may just not sub, and I have no time to find any. I would use honey but I am not sure of how it will change the consistancy.
