From Lab to Shelf: How IFF Designs Stability into Probiotics

Probiotics are living microorganisms, and their ability to deliver health benefits depends on their survival. From production to consumption, probiotics are exposed to numerous environmental stressors that can compromise viability. Probiotics only work if they remain alive—and in sufficient numbers—until they reach the gut.

While probiotic ingestion often receives the most attention, the real challenge begins much earlier. Stability must be engineered throughout the entire probiotic manufacturing process, from fermentation through storage and final use. From the moment a probiotic is consumed, it faces multiple threats: heat, moisture, oxygen, stomach acid, and bile salts. Without protection, cells can be damaged or destroyed before they ever reach the intestines.

Why microencapsulation is critical for probiotic stability and performance

To overcome these challenges, microencapsulation plays a critical role in ensuring probiotic stability. Matrix microencapsulation creates a microscale protective environment by surrounding probiotic cells with a protective formulation matrix. This matrix helps probiotics remain stable in the bottle over shelf life, survive the harsh acidic environment of the stomach, and reach the intestines alive.

By protecting cells through digestion, microencapsulation allows probiotics to colonize, interact with the gut microbiota, and deliver their intended health benefits. At IFF Health Sciences, probiotic stability is engineered from fermentation onward, supporting reliable CFU delivery and consistent performance when consumers use the finished product.

Value-chain benefits of IFF Health Sciences matrix-encapsulated probiotics

IFF Health Sciences’ matrix-encapsulated probiotics deliver benefits across the entire value chain for probiotic manufacturers and suppliers. During production, this approach supports optimized probiotic formulation, enabling high yields while maintaining cell health and potency. It also allows manufacturers to optimize cost-in-use by adding the right overage to ensure CFU counts at the end of shelf life.

Enhanced stability improves storage performance in finished applications and consumer-ready products, helping maintain potency throughout shelf life. Ultimately, optimized delivery ensures consumers receive the intended CFU dose and the full benefits of their probiotic supplements.

The probiotic manufacturing process: from fermentation to freeze-drying

There is no universal probiotic manufacturing process. Think of probiotic strains as individuals, requiring a customized approach supported by microbial expertise and formulation know-how.

• Step one: Fermentation
  • Growing the Probiotics
• Step two: Downstream processing & Stabilization
  • Time to concentrate and stabilize the cells
• Step three: Freeze-Drying
  • Creating powders with live probiotic cells.

Because each probiotic strain behaves differently, optimization across fermentation, stabilization, and drying is essential. IFF Health Sciences has dedicated expert teams focused on each stage of probiotic manufacturing, enabling tailored solutions for every strain.

Microencapsulation technology for superior probiotic stability

At IFF Health Sciences we have decades of experience in probiotics – we have built strong expertise in formulation development combining probiotics with other ingredients to make unique custom products for targeted consumer benefits. Probiotic microencapsulation further enables our probiotics to remain stable at room temperature and keep their characteristics until the end of shelf life in these finished products.

Our global Creation & Application teams apply strain-specific stability data to design innovative probiotic formulations for our customers. Lean into our experts to make your development work easier!
