Controlling moisture in gummy supplements isn't just a technical detail—it's the difference between a chewy, stable product and a sticky mess or a brittle rock. At KorNutra, we've dialed in a multi-stage drying and curing process that delivers consistent results batch after batch.
Why Moisture Matters
Too much water and you get microbial growth, ingredient breakdown, and a sticky disaster. Too little and your gummy turns hard. Our target: that perfect equilibrium that gives a pleasing chew while protecting the active ingredients.
Our Drying and Curing Process
Once the gummies are molded, they enter a carefully controlled environment designed to remove excess water—both on the surface and inside—in a controlled way.
1. Drying
This phase targets free surface moisture. Gummies move through temperature- and humidity-controlled drying tunnels. We keep tight control over three variables:
- Airflow: Consistent, laminar air means even drying across the whole batch.
- Temperature: Gentle, specific temperatures drive off water without damaging heat-sensitive ingredients or melting the gummies.
- Humidity: We dial in the relative humidity of the drying air to optimize the rate of moisture removal and avoid case-hardening (where the outside dries too fast, trapping water inside).
2. Curing
Curing is drying, but slower. It lets moisture equalize inside the gummy, which is key for final texture and stability.
- Conditioned Environment: Gummies rest in a room with tightly controlled temperature and humidity for a set period.
- Moisture Migration: This pause allows internal water to move to the surface and evaporate, giving you a uniform texture throughout.
- Starch or No Starch: Depending on the manufacturing method, gummies cure in a dusting of specialized starch or on trays without it. Both approaches absorb moisture in a controlled way.
Quality Checks and Precision Measurement
We don't fly blind. Moisture analyzers take precise readings at multiple stages, and every batch must hit our specs before it moves to packaging. This scientific approach ensures every gummy leaving our facility has the right moisture content for maximum quality and shelf life.
With precise environmental controls, staged processing, and rigorous testing, KorNutra delivers exceptional consistency in texture and stability—from the first gummy to the last.
