There is nothing more demoralizing for an event stylist than opening a 5 lb bulk bag of gummy bears 24 hours before a wedding, only to find the confections have fused into a single, un-scoopable, gelatinous boulder.
Gummy confections are hydroscopic gels operating in a delicate moisture equilibrium (16% to 18% water content by weight).
If ambient relative humidity rises above 50%, gummies absorb water vapor from the air ("sweating"). If relative humidity drops below 35%, gummies expel moisture and become rock-hard rubber.

The Gummy Stability Envelope
| Storage Variable | Safe Operating Envelope | Consequence of Exceeding Limit |
|---|---|---|
| Ambient Temperature | 62°F to 68°F (17°C – 20°C) | Above 78°F: Gelatin protein matrix collapses into liquid syrup |
| Relative Humidity (RH) | 40% to 48% RH | Above 55% RH: Surface dissolves, causing sugar weeping and clumping |
| Sunlight Exposure | Zero direct UV exposure | UV breaks down artificial and natural food colors within 4 hours |
| Air Exchange Rate | Airtight hermetic seal | Unsealed exposure causes rapid oxidation and surface hardening |
How Commercial Confectioners Polish Gummies
Top-tier manufacturers like Albanese and Kervan apply a microscopic surface coating called confectioner's glaze (a precise blend of carnauba wax and vegetable oil) in rotating panning drums.
This wax layer serves two critical functions:
When gummies are exposed to warm temperatures in shipping vans, this micro-wax coating melts. As the gummies cool, the gelatin surfaces touch without the protective oil barrier and permanently cross-link.
