The level and type of additives can affect the stability of an amorphous sugar matrix. The addition of corn syrup to sugar confections both inhibits sucrose nucleation and increases the induction time before onset of nuclei formation. In hard candies, corn syrup prevents unwanted crystallization, or graining. The effect of corn syrup on sucrose nucleation may either be through its effect on Tg or by some specific interaction. Gabarra and Hartel (1998) found that the amount of sucrose that crystallized in a sucrose–corn syrup mixture decreased with increasing percentage of corn syrup added. Tjuradi and Hartel (1995) found that higher dextrose equivalent (DE) corn syrups inhibited the rate of crystallization most, whereas Bamberger, Segall, and Lee (1980) showed that lower DE corn syrups inhibited crystallization most. This discrepancy may be explained by the different experimental conditions between studies, but further work is needed to understand the mechanisms of corn syrup inhibition of sucrose crystallization.
