Glucose Syrup: Nutrition, Pros & Cons
Glucose syrup is a highly refined liquid sweetener produced through the hydrolysis of starch. Composed primarily of glucose and maltose, it is widely used in processed foods as a sweetener, thickener, and humectant. It is classified as a free sugar with a high glycemic index, meaning it provides rapid energy but lacks essential vitamins and minerals, and should be consumed in strict moderation.
