High-fructose corn syrup.
Although HFCS is not a GMO product per se, so much HFCS is made using GM corn, we think its inclusion into these pages is justified. HFCS is widely suspected of being one of the culprits behind the obesity explosion in the United States and elsewhere during the last twenty or so years. HFCS is extensively processed and does, in fact, fundamentally alter the raw product (corn starch) used to make HFCS. The process involves changing the corn starch to glucose, and then changing the glucose to fructose. These changes cannot be made unless three separate enzymes are added to the process at three seperate points. Then, there are two more steps involved. First is a liquid chromatography step that takes the mixture to 90 percent fructose. Finally, this is back-blended with the original mixture to yield a final concentration of about 55 percent fructose—what the industry calls high fructose corn syrup. Like ordinary corn syrup, the high fructose variety is made from corn starch using enzymes.

The production process of HFCS was developed by Japanese researchers in the 1970s. HFCS was rapidly introduced in many processed foods and soda drinks in the US over the period of about 1975–1985, and usage continues to increase as sugar use decreases at a nearly one to one level. By increasing fructose content of corn syrup (glucose), the syrup is more comparable to table sugar (sucrose). This makes it useful to manufacturers as a possible substitute for sugar in soft drinks and other processed foods. Unlike sucrose, HFCS consists of a mixture of glucose and fructose, which doesn't require an enzymatic step to break it down before absorption in the intestine. Through enzymatic processing, the fructose content of corn syrup can be increased to yield a product with similar properties to table sugar. Common commercial grades of high fructose corn syrup include fructose contents of 42%, 55%, or 90%. The 55% grade is most commonly used in soft drinks and equivalent to caster sugar.

Production of HFCS.
First, cornstarch is treated with alpha-amylase to produce shorter chains of sugars called polysaccharides. Next, an enzyme called glucoamylase breaks the sugar chains down even further to yield the simple sugar glucose. The third enzyme, glucose-isomerase, converts glucose to a mixture of about 42% fructose and 50–52% glucose with some other sugars mixed in. While alpha-amylase and glucoamylase are added directly to the slurry, glucose-isomerase is packed into columns and the sugar mixture is then passed over it. This 42–43% fructose glucose mixture is then subjected to a liquid chromatography step where the fructose is enriched to approximately 90%. The 90% fructose is then back-blended with 42% fructose to achieve a 55% fructose final product. Numerous ion-exchange and evaporation steps are also part of the overall process.
