Also known as "fruit sugar", Fructose is a simple sugar commonly found in honey, melons, berries, tree fruits, vegetables, and other natural sources. Crystalline Fructose, produced from corn, should not be confused with high fructose corn syrup (HFCS), which is highly processed with varying amounts of glucose and fructose. NOW Real Food Crystalline Fructose is a pure form of this natural sugar that's ideal for a variety of cooking applications. Since Fructose doesn't recrystallize easily once it's incorporated into foods, it's ideal as a sugar substitute in recipes intended to yield soft, chewy foods, such as cookies. Fructose is the sweetest of all nutritive sweeteners, ranging from 1.2 to 1.75 times sweeter than table sugar.
