Analysis of the Tensile Strength and Rate of Biodegradability of PVA-Chitosan Blended Plastic Films Using White Shrimp (Litopenaeus setiferus) as Chitosan Source| Chapter 7 | Chemical and Materials Sciences: Research Findings Vol. 3

Chitin was extracted from white shrimps (Litopenaeus setiferus) and was processed to chitosan by the standard procedures for deproteinisation, demineralisation and multideacetylation. The chitosan product was tested with FTIR for the percentage degree of deacetylation.  Chitosan was blended with polyvinyl alcohol in different concentrations (2%, 3% and 4%) to produce biodegradable plastics. The resulting plastics were tested for variation of the blend concentrations in the tensile elongation, which is one of the characteristics needed for their use in food packaging applications. The plastic films' biodegradability with respect to time was also determined by measuring the weight loss with time during soil burrowing at four different time intervals within a month period (7.5, 7, 7, 7 days). The tensile test results showed that as the chitosan concentration is increased, the plastics showed increasing tensile strength values. Similarly, there was an observed increase in the degree of biodegradability when the film comprises of pure chitosan component.

Colon Drug Targeting: Overview on Formulation Excipient Aspects | Book Publisher International

 Colon mean delivery methods incorporating polymers that were loaded accompanying active drug(s) are with current trends for the treatment of any of local colonic diseases. The incident of prodrugs, coating of pH-delicate polymers, the use of biodegradable polymers particular to the colon are among few of bureaucracy for colon targeting policies. These biodegradable polymers that were exploited particularly by colonic bacteria offers huge promise among the many plans to accomplish address drug release to the colon. In the production of nanoparticles promoted in colon-targeted drug delivery structures, polysaccharide biomaterials have enhance more important. These procedures are spoken non-invasive medicine used to treat a variety of ailments. The chemical, enzymatic, and mucoadhesive obstacles inside the gastrointestinal (GI) tract must be checked in order to successfully transport a drug through the colon. The nanoparticles will within financial means get past these barriers and enter the colon as a result. For colon-particular drug release, many polysaccharides have been intentional as drug carrier or excipients. Among those polymers few were establish with biodegradable and non referring to practices or policies that do not negatively affect the environment types, while others are classification under water soluble or water mysterious types having particular physico-chemical traits suitable for colon targeting accompanying loaded alive drug moieties. The fact that these materials are granted to be secondhand as pharmaceutical excipients is their best property.
