HP Caps
Pullulan is a natural, water-soluble polysaccharide produced by the fermentation of starch by the fungus Aureobasidium pullulans. It belongs to the class of linear polysaccharides known as glucans.
Characteristics of pullulan capsules:
-
Vegetarian and Vegan-Friendly: Pullulan is derived from a natural fermentation process, making it suitable for vegetarian and vegan consumers.
-
Transparent and Odorless: Pullulan capsules are transparent, allowing for a clear view of the encapsulated material. They are also odorless, which can be advantageous for certain applications where the odor of the capsule material could be a concern.
-
Low Moisture Permeability: Pullulan has low moisture permeability, which helps protect sensitive ingredients from environmental conditions such as humidity, preserving the stability and efficacy of the encapsulated material.
-
High Chemical Stability: Pullulan is chemically stable, which means it does not react with the encapsulated substances. This can be important for maintaining the integrity of pharmaceuticals or sensitive compounds.
-
Ease of Production: Pullulan capsules can be manufactured using standard capsule-filling equipment, making them a practical choice for pharmaceutical and supplement manufacturers.
-
Bioavailability: Pullulan is considered biocompatible and is generally recognized as safe (GRAS) by regulatory authorities, which contributes to its use in encapsulating various substances.
