GlukoseFruktose

Glukosefruktose is a syrup composed of free glucose and free fructose obtained by enzymatic processing of starch. It is a form of glucose–fructose syrup (GFS) used as a sweetener in foods and beverages. In many markets, glukosefruktose is marketed as high-fructose corn syrup (HFCS) with varying fructose content. Common formulations include about 42% fructose (HFCS-42) and 55% fructose (HFCS-55).

Production involves breaking down starch from sources such as corn, wheat, or cassava into glucose using amylase enzymes, followed by the isomerization of part of the glucose into fructose using glucose isomerase. The resulting syrup is purified and concentrated to the desired solids and fructose-to-glucose ratio.

Uses span a wide range of processed foods and beverages. Its sweetness and moisture-retaining properties make it suitable for soft drinks, baked goods, confectionery, dairy products, jams, and other packaged foods. It can improve texture, shelf life, browning, and mouthfeel, and is often chosen as a sugar substitute in the beverage industry.

Health and regulation: Like other free sugars, high intake of glucose–fructose syrups is associated with health concerns such as weight gain and metabolic effects when consumed in excess. Regulatory authorities typically require labeling of ingredients and may impose limits on added sugars in certain products. When used within dietary guidelines, glukosefruktose is generally regarded as safe.
