What are the sugars produced by the Starch Industry?
Sugars are carbohydrates that can be classified into monosaccharides and disaccharides.:
- The main monosaccharides that are consumed are glucose and fructose.
- Examples of disaccharides include sucrose (or table sugar composed of glucose-fructose) and maltose (glucose+glucose).
According to the EU Regulation on Food Information to Consumers, ‘sugars’ means all monosaccharides and disaccharides present in food but excludes polyols (sugar alcohols).
The starch industry produces a number of different sugars. These include:
- Glucose - a monosaccharide found naturally in many foods or linked together in long chains as starch. Glucose is also known as dextrose.
- Fructose - a monosaccharide found naturally in many foods. It is the sweetest of all naturally occurring sugars. High levels of fructose are typically found in honey, in fruits - notably tree fruits (oranges, apples, etc.), berries, and melons - and in some root vegetables (such as sweet potatoes, parsnips and onions)[1]. The starch industry manufactures fructose by enzymatic conversion of glycose syrups or dextrose.
- Glucose syrups - are liquid sweeteners made from the hydrolysis of starch. They are widely used as an ingredient in confectionery. Some may contain up to 5% fructose. They are also available in dried form.
- Glucose-Fructose syrups[2] - are liquid sweeteners composed of glucose and fructose, with varying ratios of both sugars and fructose content ranging from 5 to 50%. If the fructose content exceeds 50%, the product is called fructose-glucose syrup[3].
The starch industry also produces a wide range of ingredients with sweetening properties, and which are not sugars, such as polyols Click here to find out more about Polyols.
