Biopolymeric materials

Kardam, A., Goyal, R, Arora, J.K., Raj, K.R., and Srivastava, S. 2009. Novel biopolymeric material Synthesis and characterization for decontamination of cadmium metal from waste water. National Academic and Science Letters, 32(5 and 6) 179-81. 

Viscoelastic properties of biopolymeric materials such as carbohydrates and protein can be used to characterize their three-dimensional conflgura-tion in solutions. This configuration affects their functionality in many food products. An understanding of how the molecular structure of polymers affects their rheological properties can make it possible to predict and improve the flow behavior of newly developed food products that have such... 

Biopolymeric materials in contact with a drug product should fulfill a number of requirements besides the typical requirements such as adequate mechanical properties and suitability for mass production. The polymer should be chemically resistant to the excipients of the drug product. Moreover, it should be suitable for sterilization and have good barrier properties toward water, preservatives, and preferably gases. It should comply with the existing regulations regarding the amount and toxicity of leachables. 

The number of commercially available polymer materials that can be used is rather limited. Moreover, the biopolymeric materials are typically hydrophilic, which is known to be a disadvantage owing to water adsorption [37-44]. 

Taking into account the above considerations, one can conclude that the polymeric and biopolymeric materials mentioned above are not related directly to proper cryogels and that they are probably named by such a term rather... 

Over the last 25 years a number of biopolymeric materials entered the market place that are based on renewable resources and are compostable. Especially cellulose, starch, sugar, vegetable oils and their secondary products, as well as some lignins and proteins are renewable resources that have been used as base components for bio-based and biodegradable biopolymers. 

There are many co- and ter-polymers, as well as mixtures, i.e., blends or so-called polymer alloys, combining various raw materials with biopolymeric materials.
