Food Postbiotics
Postbiotics are complex preparations obtained from complete liquid-state fermentation with food-grade probiotics followed by a controlled inactivation process. They consist of inactivated microbial cells, cell structural components, and bioactive fermentative metabolites.
Free of viable microorganisms, postbiotics retain beneficial bioactive factors that can support human health and wellness. They overcome many of the formulation limitations associated with live probiotics and can be incorporated into a wide range of conventional foods and functional food products.
Key Product Advantages
1. Excellent Processing Stability
Subjected to controlled inactivation treatment, postbiotics demonstrate strong stability against high temperatures, oxygen exposure, and pH fluctuations. They are compatible with many common food-manufacturing processes, including:
- Sterilization
- Pasteurization
- Baking
- Extrusion
- Spray-drying
Their bioactive components can remain functional during production without requiring major modifications to existing manufacturing lines. Standard food-processing equipment is generally sufficient for incorporation, helping address the viability loss commonly associated with live probiotics during food processing.
2. Simple Storage & Transportation with Long Shelf Life
Postbiotics do not require refrigeration or cold-chain logistics and can typically be stored at room temperature.
Because product stability is not dependent on maintaining viable microbial cells, shelf-life management for both raw materials and finished products becomes easier. This can help reduce warehousing and logistics costs and makes postbiotics suitable for mass-produced commercial food products intended for broad distribution.
3. Enhanced Safety Profile for Broader Population Coverage
As non-viable microbial preparations, postbiotics avoid concerns associated with microbial proliferation and may offer broader formulation flexibility for products intended for different consumer populations.
Their non-living nature makes them particularly attractive for food and nutritional applications where the stability and safety of live microorganisms may present formulation challenges.
4. Direct Mode of Action Without Intestinal Colonization
Postbiotics do not depend on live microorganisms colonizing the gastrointestinal tract. Instead, their microbial structural components and fermentation-derived bioactive compounds can interact directly with the intestinal environment.
Their non-viable nature also provides greater resistance to conditions that would otherwise reduce microbial viability during gastrointestinal transit, such as gastric acid and bile salts.
5. Synergistic Full-Fraction Fermentation Components
Postbiotics combine microbial cell-derived components with fermentation metabolites, providing multiple complementary bioactive fractions in a single preparation.
Potential functional benefits include:
- Supports intestinal barrier integrity
- Helps maintain a balanced gut microbiota environment
- Supports local immune responses
- Helps inhibit the growth or adhesion of certain undesirable microorganisms
- Supports digestive comfort and gastrointestinal wellness
6. Superior Formulation Compatibility
Postbiotics are compatible with a wide variety of commonly used food and nutritional ingredients, including:
- Prebiotics
- Vitamins
- Plant extracts
- Proteins
- Milk powders
They generally have minimal impact on the original flavor profile of the finished product and can be supplied in multiple physical forms, including:
- Powder
- Liquid
- Paste
