Hydrogenated starch hydrolysates are produced by the partial hydrolysis of starch – most often corn starch, but also potato starch or wheat starch. This creates dextrins (glucose and short glucose chains). The hydrolyzed starch (dextrin) then undergoes hydrogenation to convert the dextrins to sugar alcohols. Hydrogenated starch hydrolysates ...
Glucose syrup on a black surface. Glucose syrup, also known as confectioner's glucose, is a syrup made from the hydrolysis of starch. Glucose is a sugar. Maize (corn) is commonly used as the source of the starch in the US, in which case the syrup is called "corn syrup", but glucose syrup is also made from potatoes and wheat, and less often from barley, rice and cassava.
Lycasin is a trade name given by Roquette for hydrogenated glucose syrup (hydrogenated starch hydrolysates). [1] One of the major components of Lycasin is maltitol , derived from the hydrogenation of maltose .
Maltitol is a disaccharide produced by hydrogenation of maltose obtained from starch. Maltitol syrup, a hydrogenated starch hydrolysate, is produced by hydrogenating corn syrup, a mixture of carbohydrates produced from the hydrolysis of starch. This product contains between 50% and 80% maltitol by weight.
Glucose can be obtained by hydrolysis of carbohydrates such as milk sugar , cane sugar (sucrose), maltose, cellulose, glycogen, etc. Dextrose is commonly commercially manufactured from starches, such as corn starch in the US and Japan, from potato and wheat starch in Europe, and from tapioca starch in tropical areas.

To generate energy, the plant hydrolyzes the starch, releasing the glucose subunits. Humans and other animals that eat plant foods also use amylase, an enzyme that assists in breaking down amylopectin, to initiate the hydrolysis of starch. [3] Starch is made of about 70–80% amylopectin by weight, though it varies depending on the source.
β-amylase catalyses the hydrolysis of starch into maltose by the process of removing successive maltose units from the non-reducing ends of the chains. γ-Amylase will cleave the last α(1–4)glycosidic linkages at the nonreducing end of amylose and amylopectin , yielding glucose.
As in the production of conventional corn syrup, the starch is broken down into glucose by enzymes. To make HFCS, the corn syrup is further processed by D-xylose isomerase to convert some of its glucose into fructose. HFCS was first marketed in the early 1970s by the Clinton Corn Processing Company, together with the Japanese Agency of ...
