Freeze-Drying Solutions for Plant Extracts
Plant extracts are widely used in a variety of industries, including food and nutrition, functional beverages, health supplements, pharmaceuticals, cosmetics, and natural additives. Their activity, purity, and stability directly impact the quality of the end product. Compared to spray drying and conventional thermal drying, freeze-drying technology maximizes the retention of active ingredients such as polyphenols, saponins, polysaccharides, flavonoids, and volatile oils in plant extracts under low-temperature vacuum conditions, significantly improving powder quality and application flexibility.
Based on diverse extraction processes (such as aqueous, alcoholic, and supercritical extraction) and plant species, Sieno provides comprehensive solutions covering material property evaluation, freeze-drying curve development, powder structure control, and integrated production line design, helping customers efficiently implement high-value-added freeze-dried extract products. Applicable product categories and formats include:
Functional ingredients: ginsenosides, ganoderma lucidum polysaccharides, ginkgo flavonoids, wolfberry polysaccharides, bitter melon saponins, and vine tea flavonoids;
Plant pigments: natural coloring ingredients such as anthocyanins, chlorophyll, monascus, and capsanthin;
Herbal extracts: freeze-dried concentrated extracts of honeysuckle, salvia miltiorrhiza, scutellaria baicalensis, coix seed, aloe vera, and turmeric;
Cosmetic ingredients: freeze-dried extract powders of plant polysaccharides, asiatica glycosides, hyaluronic acid, and plant synergists;
Beverage additives/solid beverage ingredients: Suitable for reconstituted functional drinks Freeze-dried powders or granules for beverages
Core Technology Advantages:
Strong protection of heat-sensitive active ingredients: Prevents degradation and volatilization of active ingredients during high-temperature drying;
Uniform and controllable powder structure: Suitable for industrial applications such as instant solubility, tableting, and mixing stability;
Integrated concentration and drying: Suitable for highly viscous materials, high-solids systems, and fully automated loading and unloading control;
Low microbial risk and long shelf life: Extremely low moisture content makes it suitable for export and ambient temperature storage;
Fully clean process line support: Meets food-grade, health supplement-grade, cosmetic-grade, and pharmaceutical-grade standards.
Commercial Value:
Improves the application efficiency and sensory performance of extracts in industries such as food, beverages, and nutritional supplements;
Reduces the risk of ingredient inactivation and enhances the effectiveness of end-use formulations;
Enriches the functional raw material forms, enhancing brand technology content and premium pricing;
Supports a complete development path from pilot testing to pilot-scale production to mass production.
Sieno is committed to serving the global functional consumer goods market with systematic freeze-drying solutions, delivering each plant-based active ingredient in a more stable, concentrated, and user-friendly form. We not only do drying, but also help customers complete the key transformation from "extraction to commercialization".
