Ohly Launches Yeast-Derived X-SEED Shield to Limit Probiotic Losses in Freeze-Drying

Ohly, a German yeast specialist based in Hamburg, has introduced X-SEED® Shield, a new yeast-derived ingredient aimed at enhancing the survival of probiotic bacteria during freeze-drying and lyopreservation processes. This product will be showcased at Fi Europe 2026 from November 17 to 19. Traditionally, manufacturers face challenges with viable cell losses when converting probiotic cultures into shelf-stable powders, despite using sugar-based protectants that may not effectively prevent degradation. X-SEED Shield is designed to complement these protectants, enhancing their efficacy without replacing them.

The ingredient functions at two critical stages: providing protection during the freeze-drying process by mitigating cell damage from ice crystals and offering antioxidant support, and supplying essential nutrients upon rehydration to facilitate the resumption of metabolic activity. Created from primary-grown baker's yeast and marketed as a clean-label component, X-SEED Shield operates effectively at low dosages and seamlessly integrates into existing manufacturing processes without altering product appearance. According to Claudia Stoecker, Commercial Director for Bionutrients at Ohly, the launch responds to increasing global demand for high-quality probiotic products while improving manufacturing efficiency and product stability throughout shelf life.
