Localized infrared radiation was applied to gummy candy to observe its behavior during heating.
The irradiated area rapidly reached high temperatures, accompanied by the generation of white smoke and sudden foaming, with gas being released from within the material.
This behavior is attributed to the softening and thermal decomposition of sugars and gelling components contained in the gummy candy, resulting in the generation of volatile components.
This video demonstrates the relationship between the characteristics of localized infrared heating, which delivers high energy density in a short time, and the foaming and thermal decomposition behavior of food materials.
