9057-02-7 Usage
Description
Pullulan is a linear homopolysaccharide of glucose, which is produced as a water-soluble, extracellular polysaccharide by certain strains of the polymorphic fungus Aureobasidium pullulans (De Bary) Arnaud.
Pullulan has adhesive properties and can be used to form fibers, compression moldings, and strong, oxygen-impermeable films. In food industry, pullulan films can be employed as coating or packaging materials of dried foods, as a binder for tobacco, seed coatings and plant fertilizers, as low viscosity filler in beverages and sauces, as binder and stabilizer in food pastes, to inhibit fungal growth in foods. In pharmaceutical industry, pullulan can be used as a denture adhesive, in the sugar coated pharmaceutical compositions to prevent brownish color change of the composition. Pullulan can also be used in cosmetics, lotions, and shampoos.
Uses
Different sources of media describe the Uses of 9057-02-7 differently. You can refer to the following data:
1. serum amylase substrate
2. pullulan is used as a binder and film former in a variety of formulation categories (skin, make-up and hair), it is a polysaccharide derived from the Aureobasidium pullulans yeast.Pullulan is a polysaccharide polymer consisting of D-Maltotriose (M159000) units; a trisaccharide resulting from the digestion of Amalose by α-Amalase. Pullulan has been used in a study to assess bone tissue engineering. Addition of pullulan has improved the elongation at break of gelatin based edible film when the amount was 50% (wt. %).
3. Pullulan has been used in a study to assess bone tissue engineering. It has also been used in a study that investigated anti-fog applications.
Definition
Different sources of media describe the Definition of 9057-02-7 differently. You can refer to the following data:
1. A biodegradable polysaccharide made
by yeast fermentation, originally developed in
Japan. Its adhesive and oxygen impermeable prop-
erties enable it to be used to coat pharmaceutical
products. It is water soluble, odorless, and edi-
ble; these properties
2. pullulan: A water-soluble polysaccharidecomposed of glucose unitsthat are polymerized in such a wayas to make it viscous and impermeableto oxygen. Pullulan is used in adhesives, food packaging, andmoulded articles. It is derived fromthe fungus Aureobasidium pullulans.
General Description
Pullulan Standards are mostly used to obtain molecular mass distribution of cellulosic samples. It mainly consists of polymaltotriose units linked together by α-(1→6) linkages.

Check Digit Verification of cas no
The CAS Registry Mumber 9057-02-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,5 and 7 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 9057-02:
(6*9)+(5*0)+(4*5)+(3*7)+(2*0)+(1*2)=97
97 % 10 = 7
So 9057-02-7 is a valid CAS Registry Number.
