The health benefits of probiotics rely on their ability to remain viable in sufficient numbers in food products. According to FAO/WHO (2002), probiotic foods must contain at least 10⁶ CFU/g of live microorganisms to confer health benefits (12–14 ). However, maintaining the stability and viability of probiotics throughout their journey—from production to consumption—remains a significant challenge.

Ensuring Probiotic Viability: Strategies for Stability and Efficacy in Food Products

Introduction

The health benefits of probiotics rely on their ability to remain viable in sufficient numbers in food products. According to FAO/WHO (2002), probiotic foods must contain at least 10⁶ CFU/g of live microorganisms to confer health benefits (1214 ). However, maintaining the stability and viability of probiotics throughout their journey—from production to consumption—remains a significant challenge.

The Importance of Probiotic Viability

To ensure health benefits, probiotics must survive gastrointestinal (GI) transit and reach the colon in an active state. This viability is threatened by various stress factors encountered during:

Factors Influencing Probiotic Stability

Probiotic strains exhibit variations in functional properties, stability, and efficacy. These differences are influenced by:

Strategies to Improve Probiotic Stability

Several innovative methods have been explored to enhance probiotic viability and stability:

  1. Stress Adaptation: Pre-treatment techniques that prepare probiotics to withstand environmental stresses.
  2. Selective Pressure Treatment: Exposing probiotics to controlled stress conditions to enhance resilience.
  3. Mutagenesis and Genetic Modification: Altering probiotic DNA to improve stability and efficacy, although genetically modified strains are not widely accepted in food applications (1 5).
  4. Encapsulation Technology:

Encapsulation: The Gold Standard for Probiotic Protection

Encapsulation involves enclosing probiotics within a protective matrix, shielding them from adverse conditions while maintaining their functionality. Benefits include:

Challenges and Considerations

While encapsulation offers significant advantages, the overall process must balance cost-effectiveness and scalability. Additionally, regulatory acceptance and consumer preferences play a crucial role, especially when genetically modified strains are involved (16, 17 ).
