Pediococcus pentosaceus Freeze-dried Powder
Overview
Pediococcus pentosaceus Freeze-dried Powder is a lyophilized form of the lactic acid bacterium Pediococcus pentosaceus. This microorganism is widely recognized for its role in food fermentation, probiotic formulations, and animal feed enhancement. Freeze-drying ensures long-term stability and ease of storage, making it a preferred format for industrial applications. The powder is produced under controlled conditions to maintain high viability and functional properties. It is commonly used in the food and beverage industry for fermentation processes, as well as in dietary supplements and animal nutrition for its probiotic benefits.
Physical and Chemical Properties
Pediococcus pentosaceus Freeze-dried Powder typically appears as an off-white to light yellow powder. It is soluble in water, allowing for easy reconstitution. The freeze-drying process removes moisture while preserving the bacterium's viability and metabolic activity. Key properties include high thermal stability in its dried form, resistance to acidic conditions, and the ability to produce lactic acid. These characteristics make it suitable for applications in acidic food matrices and digestive environments.
Main Applications
The primary application of Pediococcus pentosaceus Freeze-dried Powder is in the food industry, where it serves as a starter culture for fermented products like sausages, cheeses, and vegetables. Its ability to produce lactic acid and inhibit pathogenic bacteria makes it valuable for food preservation. In the probiotic sector, it is used in dietary supplements and functional foods to support gut health. Additionally, it is incorporated into animal feed to improve digestion and immune response in livestock and poultry.
Safety and Storage
Pediococcus pentosaceus is generally recognized as safe (GRAS) for use in food and feed. However, standard laboratory handling procedures should be followed to avoid contamination. The powder should be stored in a cool, dry place, preferably at 2-8°C, to maintain viability. Exposure to moisture and high temperatures should be avoided, as these can reduce the product's shelf life. Properly stored, the powder can remain viable for up to two years.
B2B Procurement Guide
When procuring Pediococcus pentosaceus Freeze-dried Powder, B2B buyers should verify the strain's authenticity and viability count, typically measured in colony-forming units (CFU) per gram. Reputable suppliers provide certificates of analysis (CoA) detailing these parameters. Bulk purchases often come with discounts, but buyers should ensure proper storage conditions during transit. It's also advisable to request samples for testing before large-scale procurement to confirm compatibility with the intended application.
