How should I evaluate the sample, and do you support stability testing?

Question

Accepted Answer

Evaluate on aroma, pH, solubility in your formula and side-by-side comparison with your reference; for stability we can support temperature, light and time-point testing.

We can also run accelerated aging on sealed samples and report pH, aroma and microbial results at time points.Send your test protocol and we will align our batch records and stability data to it.
