Glucose Syrup DE42 in gelato
Glucose syrup DE42 is a regular-conversion, acid- or acid-enzyme hydrolysed starch syrup (typically corn) with a dextrose equivalent of about 42 and roughly 80% dry solids. In gelato it is a bulking, body-building sugar that adds solids and anti-crystallization power with only moderate sweetness.

Used to replace part of the sucrose, glucose syrup DE42 raises total solids and gives body, chew and a slower, more controlled melt without over-sweetening. Because its dry-basis POD (~50) and PAC (~80) are well below sucrose, swapping sucrose for DE42 lowers both the sweetness and the freezing-point depression of a mix, firming the gelato and improving scoopability. It also fights ice-crystal growth and improves shelf life. Reach for it when a recipe needs more solids and structure but is already sweet enough, or to keep sorbets from becoming too soft.
Origin & background
Starch-to-glucose conversion dates to 1811, when Russian chemist Gottlieb Kirchhoff hydrolysed potato starch with acid to make glucose. The 42 DE grade became the industry-standard "regular conversion" syrup; the Codex Alimentarius standard for glucose syrup requires a dextrose equivalent of at least 20 and total solids of at least 70%.
