High fructose corn syrup, the commercial version of corn syrup is used in sweetening common items of food such as cookies, yogurt, cola and canned fruit. In short, it is a man-made caloric food sweetener. Corn syrup is being produced using enzymes and acids sometimes to break down corn starch into fructose, glucose and simple sugars.
The chemical composition of corn syrup resembles closely to that of table sugar, sucrose. It is composed of 50 percent glucose and 50 percent fructose. High fructose corn syrup commercially used comes in two rations, 45 percent glucose to 55 percent fructose used in soft drinks, 58 percent glucose to 42 percent fructose used in sweetening ice cream, desserts and baked goods. They share the same caloric value as well.
The process of manufacturing corn syrup started in 1960s. To begin with, corn kernels are drenched in warm water that contained sulfur dioxide. Through this warm solution, the kernels are hydrated which made it easier to break down the hull, starch, protein and oil components. Once soaking is done, the kernels are the wet milled to eliminate the oil that contained germ. Then the remaining corn starch will be washed.
Three enzyme types are added to the resulting mixture of water and starch to break down the starch into fructose and glucose and create the desired or required balance of the two. The syrup that is produced in the process is then placed through evaporation process to produce the desired consistency before it will be produced for shipping.
High fructose corn syrup came under close scrutiny in the recent years. It is found in most of the pre-packaged foods. The Department of Agriculture of America found that about 39% of the nutritive sweeteners that are being consumed in the country are actually in the form of commercial version of corn syrup. But it was blamed for the cause of the ever-increasing waist lines of people. However, it was proven that high fructose corn syrup is not likely to cause any negative or adverse effects to obesity for those individuals who have consumed foods that contained this type of sugar.
