What are Sweeteners?

Sweeteners are carbohydrates are characterized by their sweet taste. The most common ones in baking are mono and disaccharides.

These ingredients are essential components of baked goods. They are added to yeast-leavened products, as well as to chemically-leavened sweet goods like batter cakes and cookies. Although, then they are used in larger quantities.

  • Sucrose
  • Lactose
  • Crystalline glucose
  • Brown sugar
  • Molasses
  • Liquid sugar
  • Invert sugar syrup
  • Honey
  • Maple sugar
  • Glucose or corn syrup
  • High fructose corn syrup
  • High-intensity sweeteners
  • Sugar alcohols or polyols

Origin

Sweeteners are widely found in nature as components of biomass. They can also be produced from plant sources that are rich in starch. They are naturally found in fruits, stevioside leaves, milk, sugar cane, sugar beet, honey, maple tree, and in smaller amounts in cereals and grains.1

Function

Some of the functions of these ingredients are:2,3

  • Sweetening
  • Tenderizing
  • Batter aeration (crystallized sugars)
  • Fermentation control through osmotic pressure
  • Yeast nutrient / food
  • Bulking agents (body)
  • Flavoring agents (molasses, honey, malt, maple sugar)
  • Browning or crust coloring agents
  • Humectants
  • Texture builders
  • Shelf‐life extenders by lowering water activity

They can be classified according to their caloric content as:

  1. Nutritive or caloric sweeteners
  2. Non-nutritive or high-intensity sweeteners

Nutritive options can be either mono or disaccharides, or a mixture of both:

Monosaccharides (simple sugars) Disaccharides (2 simple sugars, bound by glycosidic linkage)
  • Fructose
  • Glucose
  • Galactose
  • Maltose: 2 units of glucose
  • Sucrose: 1 unit of fructose + 1 unit of glucose
  • Lactose: 1 unit of galactose + 1 unit of glucose

Non-nutritive sweeteners are zero or low-calorie sweeteners, however their usage in baking is limited.

Commercial production

The following table summarizes the production processes used to manufacture different ingredients:1,3,4,5

Raw material or source Process Product obtained
Sugarcane, sugar beets Sugar refining
Sucrose
  • Addition of water or dilution
  • Acid hydrolysis and/or enzymatic conversion
Starch from cereals, tubers and/or roots
  • Enzymatic conversion with amylases for liquid forms
  • Additional evaporation, crystallization and centrifugation for dry forms
Milk Separation, concentration and drying Lactose
Nectar of plant blossoms, and honey bees Natural production process Honey
Maple tree (Acer saccharum) Concentration of sugars in the sap produced by maple tree Maple sugar
Sucrose and other sugars Chemical reactions High intensity sweeteners
Monosaccharides and starch sources Enzymatic conversion and further reduction reaction (hydrogenation) Polyols

Application

The type and amount of a given sweetener are selected based on the its contribution to doughs, batters or finished products, namely:

  • Fermentability: Essential for yeasted products
  • Sweetness level or relative sweetness
  • Total solids and moisture content: liquid (pumpable), or dry sweeteners. This is critical for  chemically-leavened batter-based products like cakes.

These criteria must be properly stated in a sweetener’s spec sheet.

Nutrition and health

Consumption of excessive amounts of sugars in the diet may lead to metabolic imbalance. Of special importance is increased risk of chronic diseases such as obesity, diabetes, and cardiovascular disease.6
