Description

Propionibacteriumfreudenreichii-Cultureddextrose is a specialized fermentation-derived ingredient, produced by culturing dextrose with the bacterium *Propionibacterium freudenreichii*. This process is critical for generating key metabolites and bioactive compounds used in advanced food and nutraceutical applications. It is essential for manufacturers in the dairy, probiotic, and functional food industries seeking natural and effective fermentation agents.

Application

• Probiotic Culture Production: As a primary substrate for the growth and propagation of *Propionibacterium freudenreichii* and other beneficial bacteria.
• Dairy Fermentation: Used in the production of Swiss-type cheeses (e.g., Emmental, Gruyère) to develop characteristic flavor compounds and "eyes" (holes).
• Nutraceutical & Functional Food Ingredient: A source of bioactive compounds like propionic acid and vitamin B12 for dietary supplements and fortified foods.
• Starter Culture Media: A key component in fermentation media and growth promoters for industrial starter cultures.
• Animal Feed Additive: Utilized in feed formulations to promote gut health and improve nutrient absorption in livestock.
• Biotechnological Research: Serves as a defined medium component for microbiological studies and metabolic pathway research.

Quality Control

Our Propionibacteriumfreudenreichii-Cultureddextrose is produced under controlled conditions to ensure batch-to-batch consistency and microbial purity. Quality is assured through rigorous testing protocols, including microbial enumeration, absence of pathogens, and analysis of key metabolites. Certificates of Analysis (COA) documenting purity, activity, and safety are available upon request to support your quality management systems.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at temperatures between 2°C and 8°C (refrigerated) to maintain microbial viability and product stability. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption.
