Malvern, PA (January 18, 2005) - US consumers are becoming more aware of the health benefits of probiotics, creating an eager market for new food products that contain them. Unfortunately, preserving the activity of live cultures during processing, storage and digestion is difficult due to their high susceptibilities to oxygen, shear, heat, and acids. Fortunately, new research shows that adding Beneo™, a prebiotic food ingredient, protects the probiotics during processing and during transit through the digestive tract.
Studies previously conducted have shown that Beneo™ oligofructose has a positive effect on the survival of probiotic cultures in fermented dairy products during processing and shelf-life. While this research shows that the probiotic bacteria are still viable at the time of consumption, it does not indicate whether the bacteria are vital enough to survive the severe stress of digestive conditions. ORAFTI has conducted a new study to determine if Beneo™ also promotes the survival of probiotic bacteria during digestion in the body.
The study tested yogurts containing the probiotics Lactobacillus rhamnosus or Lactobacillus casei, with 3% Beneo™ P95 or Beneo™ Synergy 1. Samples of the yogurt were pulled at intervals up to 10 weeks to test the viability of the probiotic cultures over shelf life and to get an indication of the vitality of the probiotics after consumption by using a model in vitro digestive system.
The results indicated:
• At 10 weeks, both types of Beneo™ (added at 3%) were shown to protect probiotic bacteria over shelf life with no change in viability
• The yogurt processed through the in-vitro stomach/intestine with Beneo™ showed no significant difference in L. Rhamnosus cell counts versus a 36% decrease in counts for the control yogurt with no added Raftilose.
• The yogurt with L. casei cultures showed a 5% decrease in culture vitality with Beneo™, while the control yogurt without added Beneo™ suffered a 19% decrease in cell counts after simulated digestion.
The results indicate that Beneo™ protects the probiotics through both storage and digestion. The clean flavor and formulating flexibility of Beneo™ appears ideal for use in synergy with probiotics in processed food applications.
