Facts About Caloric Sweeteners
Sweeteners that contribute calories to the diet are called caloric or nutritive sweeteners. All common caloric sweeteners have the
same composition: they contain fructose and glucose in essentially equal proportions. All caloric sweeteners require processing
to produce a food-grade product.
| Fructose | a simple sugar commonly found in fruits and honey |
| Glucose | a simple sugar that serves as a building block for most carbohydrates |
| High fructose corn syrup (HFCS) | free (unbonded) fructose and glucose in liquid (syrup) form; produced from corn |
| Sucrose | crystalline white table sugar; produced from sugar cane or sugar beets; fructose and glucose
bonded together |
| Invert sugar | free fructose and glucose in liquid (syrup) form; produced from the breakdown of sugar |
| Hydrolyzed cane juice | free fructose and glucose in liquid (syrup) form; produced from the breakdown of cane juice |
| Honey | liquid (syrup) product; principally free fructose and glucose with minor levels of other sugars and
some trace minerals |
| Fruit juice concentrate | concentrated, filtered, clarified fruit juice; fructose-to-glucose ratio varies by fruit source, but generally
equivalent to other nutritive sweeteners (orange juice and grape juice have a fructose to glucose
ratio of 1 to 1, while apple juice has a ratio of 2 to 1) |

Nutritional Characteristics
Common caloric sweeteners share the same general nutritional characteristics:
- each has roughly the same composition-equal proportions of the simple sugars fructose and glucose;
- each offers approximately the same sweetness on a per-gram basis;
- one gram (dry basis) of each adds 4 calories to foods and beverages;
- each is absorbed from the gut at about the same rate;
- similar ratios of fructose and glucose arrive in the bloodstream after a meal, which are indistinguishable in the body.
Since caloric sweeteners also are nutritionally equivalent, they are interchangeable in foods and beverages with no measurable
change in metabolism.
What if caloric sweeteners are removed from foods?
To replace one caloric sweetener with another provides no change in nutritional value. To remove sweeteners entirely from their
commonly used applications and replace them with high intensity sweeteners would drastically alter product flavor and sweetness,
require the use of chemical preservatives to ensure product quality and freshness, result in a reduction in perceived food quality (bran
cereal with the caloric sweeteners removed would have the consistency of sawdust), and would likely require the addition of bulking
agents to provide the expected texture, mouth feel or volume for most baked goods.
Why is HFCS used in specific applications?
If consumers are sometimes surprised to find HFCS in particular foods or beverages, it may be because they do not have a full
appreciation of its versatility and value. HFCS often plays a key role in the integrity of food and beverage products that has little to
do with sweetening. Here are some examples in popular products:
| Baked goods | HFCS gives a pleasing brown crust to breads and cakes; contributes fermentable sugars to yeastraised
products; reduces sugar crystallization during baking for soft-moist textures; enhances flavors
of fruit fillings |
| Yogurt | HFCS provides fermentable sugars; enhances fruit and spice flavors; controls moisture to prevent
separation; regulates tartness |
| Spaghetti sauces, ketchup and condiments | HFCS enhances flavor and balance - replaces the "pinch of table sugar grandma added" to enhance
spice flavors; balances the variable tartness of tomatoes |
| Beverages | HFCS provides greater stability in acidic carbonated sodas than sucrose; flavors remain consistent
and stable over the entire shelf-life of the product |
| Granola, breakfast and energy bars | HFCS enhances moisture control, retards spoilage and extends product freshness; provides soft
texture; enhances spice and fruit flavors |
