Retain Potency When Formulating Botanical Extracts
Stand out with deeper color and fresher aroma than competing products.
Common drying methods
rely on heat and long exposure, reducing phenolics and antioxidant capacity and stripping volatiles, which dulls color and aroma and weakens potency.
Freeze-drying
protects sensitive compounds from heat and oxygen, retaining phenolics and volatiles, delivering brighter color and fresher aroma with scalable tray processing and strong material recovery.
Freeze-Drying Retains More Polyphenols and Flavonoids than Spray-Drying

| Drying Method | Polyphenol retention (TPC) | Flavonoid retention (TFC) |
|---|---|---|
| Spray-drying | ~67% | ~62% |
| Freeze-drying | ~91% | ~93% |
