Glucose Syrup

Glucose syrup is a concentrated, neutral-tasting syrup produced by hydrolyzing starches (commonly corn, wheat, potato, or rice) into shorter-chain sugars dominated by glucose. Compared with sucrose, it is less sweet but excels at controlling crystallization, adding body, and retaining moisture. Its functionality is often described by DE (dextrose equivalent), which correlates with sweetness, fermentability, and viscosity.

In the kitchen, glucose syrup is prized in confectionery, ice cream, pastry, and sauces for preventing graininess, improving chew, and delivering a glossy finish without strong flavor. It differs from high-fructose corn syrup in that it contains predominantly glucose with minimal fructose. Commercial products are typically gluten-free even when wheat-derived, but labeling should be checked if allergens are a concern.
