Description:

Empty vegetarian capsules made from water - soluble natural polysaccharides: Pullullan (see below) Other information gives detail and comparison with HPMC. GMP manufacturing standard and quality control. Certified vegetarian.

High oxygen impermeability, this is particularly advantageous because this means encapsulation of product that is sensitive to oxidation is protected.

Can be used with any of the capsule machines from FETON.

Packaged in a convenient resealable stand up Daklapack for easy use.

AVAILABLE NOW

1: Bright-Poly is the best oxygen barrier:

Pullulan based capsules are:
- 250 time more better oxygen barrier than HPMC based capsules
- 9 time more better than gelatin based capsules

That means:
- Better protected nutrients
- Longer shelf life
- Improved stability

2: Environment friendly and health conscious:

Pullulan is water extracted from fungi grown on starch substrate, much like the mushroom growing on fertile ground. There are no toxic chemicals involved in growing, harvest and extract pullulan. So it is very natural and environment friendly.

HPMC is manufactured from pure cellulose (from tree) using a lots of chemicals, some of the Petro- chemicals used are noted by EPA as toxic and environmentally damaging.

3: Other reasons to use Bright-Polys:

- Bright-polys are the only non-brittle pullulan capsules available.
- Bright-polys retain moisture as well as gelatin capsules.
- Bright-polys run perfectly on all high speed automatics capsule machines, reduce down-time and improve efficiency.

Pullulan or HPMC?

1: What is pullulan:

Pullulan is naturally occurring, as a cell wall component for fungus Aureobasidium pullulans.
Pullulan is produced from starch by the fungus Aureobasidium pullulans.
As an edible, bland and tasteless polymer, the chief commercial use of pullulan is in the manufacture of edible films that are used in various breath freshener or oral hygiene products such as Listerine Cool Mint PocketPaks. As a food additive, it is known by the E number E1204.
Chemistry: CAS number [9057-02-7]; Molecular formula (C6H12O5)n
Pullulan is a polysaccharide polymer consisting of maltotriose units, also known as α-1,4- ;α-1,6-glucan. Three glucose units in maltotriose are connected by an α-1,4 glycosidic bond, whereas consecutive maltotriose units are connected to each other by an α-1,6 glycosidic bond.


2: Why pullulan:

We choose pullulan over HPMC, because of following factors:
1): Pullulan is more natural, involving no toxic chemicals, much less environment polluting in its production process
2): Pullulan possess more potential for price reduction when produced in mass, because the fermentation technology used is widely used and very mature.
3): Pullulan film is 250 times stronger oxygen barrier than HPMC film, 9 time stronger than gelatin film
4): Pullulan is much more inert than gelatin or HPMC, so there is no interaction with products it intended to deliver


3: How pullulan is made

Commercially, Pullulan is from fermentation process. Aureobasidium pullulans grow on the carbohydrate substrate (sugar or starch). Then Aureobasidium pullulans is harvested. Followed by rupture the cell with either enzyme or physical force. Pullulan then is extracted using simple water extraction process. There are no environment damaging waste, or carcinogenic material used.


4: What is HPMC (Chemical names: Propylene glycol ether of methylcellulose)

Hydroxypropyl methylcellulose is a methylcellulose modified with a small amount of propylene glycol ether groups attached to the anhydroglucose of the cellulose. The dry product contains 19 to 30 per cent of methoxyl (-OCH3) groups and 3 to 12 per cent. of hydroxypropyl (-OCH2CHOHCH3) groups.


5: How HPMC is made:

The cellulose ethers are manufactured by a reaction of purified cellulose with alkylating reagents (methyl chloride) in presence of a base, typically sodium hydroxide and an inert diluent. The addition of the base in combination with water activates the cellulose matrix by disrupting the crystalline structure and increasing the access for the alkylating agent and promotes the etherification reaction. This activated matrix is called alkali cellulose (Kirk-Othmer, 1993). During the manufacture of HPMC alkali cellulose reacts with methyl chloride to produce methyl cellulose and sodium chloride. Side reactions of the methyl chloride and sodium hydroxide produce methanol and dimethyl ether by-products. The methylcellulose is then further reacted with the staged addition of an alkylene oxide, which in the case of HPMC is propylene oxide (Kirk Othmer, 1993; Dow, 2002).
After this reaction, MC and HPMC are purified in hot water, where they are insoluble. Drying and grinding completes the process.

6: Chemicals involved in manufacturing HPMC

RcellOH:NaOH + CH3Cl + NaCl +RcellOCH3 + x C H3CH ââ?¬â??O CH2 + Rcel ââ?¬â?? OCH3 +O (OCH2 CHCH3)xOH.
Dangerous chemicals involved:
Methyl chloride (CH3Cl) is colorless gas with a faint, sweet odor that is not noticeable at dangerous concentrations.
Synthetic forms are a chlorinated hydrocarbon derived from petroleum, and a suspected carcinogen. (Lewis, 1992; NJ 1998).
Propylene oxide is also a petroleum derivative.
EPA ââ?¬â?? Clean Air Act Amendments ââ?¬â?? final rule for National emission standards for hazardous air pollution (NESHAP) includes cellulose ethers production source category as including major sources of emissions of hazardous air pollutants.
