Pullulan Capsules are made of pullulan, a natural polysaccharide of non-animal origin. They can be used as vegetarian alternative to common gelatine hard capsules. Pullulan is not produced by chemical modification, and is therefore 100% natural, unlike HPMC.
Capsules are available in size 00, 0 and 1. Transparent capsules are always available in stock, minimum order quantity for coloured capsules are 1 million pieces.
Composition of Pullulan Capsules
- Polysaccharides (Poly Maltotriose - Pullulan)
- Purified Water
Features
Pullulan Capsules have the following unique features:
- Excellent oxygen barriere properties of pullulan, so that these capsules protect 250 times better against oxidation than HPMC capsules and 9 times better than gelatine capsules.
- Because of non-hygroscopic properties of pullulan, the likelihood of a potential crosslinking with encapsulated substances is significantly reduced.
Pullulan Capsules are especially suitable to protect sensitive neutraceuticals like plant extracts or anti-oxidants and pharmaceuti- cal active ingredients.
Advantages of Pullulan
Pullulan is:
- not produced by chemical modification, 100% natural
- manufactured by natural fermentation of plant extracts
- neither genetically modified nor pathogenic
- well known in the pharmaceutical and food industry
- non-allergenic
- starch- and gluten-free
Chemical structure of pullulan
What is pullulan?
Pullulan is a biopolymer with unique properties. It is a polysaccharide produced by the fermentation of carbohydrate (starch/sugar) by the ubiquitous fungus Aureobasidium pullulans. Chemically, it consists of repeated unit of maltotriose units where three glucose units in maltotriose are connected by an alpha-1,4 glycosidic bond and consecutive maltotriose units are connected to each other by an alpha-1,6 glycosidic bond. This typical linkage pattern in fact render some distinctive physical traits which are different from many known polysaccharide. One interesting characteristic is its high adhesevity that leads to the formation of strong films with very low oxygen permeability.
Pullulan is a white to off white powder and is flavorless, odorless and extremely stable. It is non toxic and non immunogenic in nature and readily dissolves in water.
