- Melatonin addition should be evaluated for heat exposure and uniform distribution.
| - Temperature, time, solids content, viscosity, and batch homogeneity.
- Control of foaming, scorching, and excessive moisture loss.
- In-process sampling for active distribution where appropriate.
| Request validated process parameters rather than relying only on nominal temperature settings; active stability is formulation-dependent. | Batch manufacturing record, temperature charts, in-process test results, deviation reports. |
| Depositing and Molding | - Gummy mass is deposited into starch molds or deposited directly into suitable molds.
- Shape, target fill weight, and cavity design determine the final dose uniformity.
- Deposit temperature and equipment speed are adjusted to maintain accurate weight and appearance.
| - Average weight and individual weight variation.
- Shape integrity, surface defects, air pockets, and sticking.
- Correct mold identification and line clearance.
| Approve a physical sample or golden sample covering shape, color, size, weight, and chew texture before commercial production. | Start-up approval, weight checks, mold-cleaning records, equipment setup verification. |
| Setting, Drying, and Conditioning | - Setting and conditioning time depends on the gelling agent, solids content, humidity, and gummy size.
- Controlled temperature and relative humidity help reduce stickiness and batch-to-batch variation.
- Final moisture and water activity must be established through product-specific stability work.
| - Water activity, moisture, texture, and dimensional stability.
- Microbiological testing according to the product category and market requirements.
