E915 – Pentaerithrytol esters of colophane
Glazing agentDescription
Mixture of pentaerythritol esters of wood rosin or gum rosin
Notes
This additive is made by combining glycerol (also known as glycerin, a sweet, syrupy liquid) with rosin, which comes from pine trees. Wood rosin or gum rosin is the sticky, resinous substance that's extracted from pine tree sap and then refined. When glycerol is chemically combined with this rosin through a process called esterification, it creates compounds that have useful properties for food applications while being much less sticky than the original tree resin. Glycerol esters of wood rosin work as a glazing agent, primarily used in chewing gum to create that smooth, glossy surface you see on many gum products. This coating helps prevent the gum from sticking to packaging, gives it an attractive appearance, and can help preserve the gum's texture and flavor. You might also find it in some other confectionery products where a similar protective coating is needed. This additive is derived from plant sources (pine trees and glycerol, which can be plant-based), making it generally suitable for vegetarians and vegans, though you'd want to verify the glycerol source with manufacturers if this is a concern. It's been approved for food use and is considered safe for consumption. The additive has been used in food products for many years without significant safety concerns when used within approved limits.
