Heat-sensitive vitamins and probiotics can survive gummy manufacturing, but only when the manufacturer designs the process around the heat.
The Challenge of Heat-Sensitive Nutrients
Vitamin C breaks down fastest in the 85-95°C range and starts degrading above 70°C. Thiamine, folate, and B12 also degrade under heat. Probiotics begin dying off above 115°F. Pectin bases cook at 220-240°F to set; gelatin, the gentler option, runs at 160-180°F. Both exceed what raw actives can take.
Advanced Manufacturing Solutions
- Low-Temperature Processing: Keep the base at the low end of its range and add actives after the gel cools.
- Post-Production Incorporation: Dust or spray the vitamin onto the cooled gummy so it never meets the hot base.
- Stable Formulations: Use encapsulated or protected forms that tolerate heat and moisture up front.
- Precise Process Control: Hold time, temperature, and pH in tight windows, since degradation depends on all three.
Label Claim Through the End of Shelf Life
For dietary ingredients a manufacturer adds, the product must contain 100% of the amount declared on the label, except for analytical-method deviation, and that holds to the end of the stated shelf life. So formulators build in overage, extra heat-sensitive nutrient sized from stability data, so the product still meets claim at expiry. A 1,000 mg vitamin C gummy might carry about 30% more ascorbic acid to cover two years of loss. Overage cuts both ways: too little mislabels the product, and too much on nutrients with upper limits, such as vitamins A and D, adds its own risk.
Ensuring Quality and Potency
None of this is visible without testing. A manufacturer assays the finished gummies with HPLC or UV methods to confirm the actives meet label claim, then repeats the assay through the shelf life with accelerated and real-time stability studies.
