Therefore, corn syrup containing fructose can be considered as a natural sweetener with a high preservative effect.

Corn syrups contain different amounts of fructose and glucose monosaccharides, which are introduced based on the amount of fructose. Two common types of fructose syrup include 42% and 55% fructose syrup, which are introduced as HFCS42 and HFCS55. Each of these compounds show different properties based on the amount of fructose. In order to achieve some technological properties, amounts of glucose and fructose monosaccharides are mixed with each other in order to have better and more applicability. Among these mixtures, corn syrups containing different percentages of fructose can be mentioned.
