Sugar produced from cornstarch; comprised of glucose (dextrose), maltose and higher sugars; 70 percent to 80 percent solids Sugar based sweeteners are those such as that developed from corn starch. The development of the various types of corn syrups, maltodextrins, and high-fructose corn syrup from corn starch sources could be called one of the greatest changes in the sugar and sweetener industry over several centuries. In the late 1800s it was found that corn starch could be hydrolyzed and a sugar formed. It was not until the 1970s that it became commercially a major product bringing about changes in the food industry. Over-reliance in the food industry and over-indulgence by consumers of these processed sugars, particularly high fructose corn syrup, has most likely contributed to obesity in many western countries. These sweeteners are processed and refined using a series of separation, and grinding processes. Finally, the products are converted and fermented. From this processing a five classes of corn sweeteners are formed. This does not include the corn syrup conversion into high-fructose corn syrup.
