How do you use glycerin in industrial production of cakes?

In industrial cake production, glycerin is used primarily as a humectant, which helps retain moisture in the cakes, ensuring they remain soft and fresh for longer periods. Additionally, glycerin can enhance the texture and stability of the batter, contributing to a more uniform crumb structure. It also acts as a sweetener, providing a subtle sweetness without the crystallization issues associated with sugar. Overall, glycerin improves the shelf life and quality of the final product.
