Glucose isomerase is widely used in the food industry for the production of high-fructose corn syrup (HFCS), a sweetener that is commonly used in beverages, baked goods, and processed foods. The enzyme catalyzes the conversion of glucose to fructose, which is sweeter and more soluble, making it a desirable ingredient in many food products. Additionally, it is employed in the biofuel industry to convert glucose into fructose, which can then be fermented into ethanol. Its application in biotechnology also extends to the production of other sugar derivatives and specialty chemicals. The enzyme’s ability to efficiently isomerize sugars under mild conditions makes it a valuable tool in industrial processes.
