Abstract
The study aimed to synthesize ascorbic acid (AA) loaded carboxymethyl guar gum (CMG) hydrogel based film cross linked by citric acid (CA). Bioactive films (CMG-CA and CMG-CA-AA) were synthesized by solvent casting method. The flexibility and mechanical strength of the bioactive film (CMG-CA-AA) were enhanced by the addition of glycerol and optimized by analyzing tensile strength. The structural, morphological and thermal analysis was done by FTIR, XRD, SEM and TGA. Further, the films were evaluated for its anti-oxidant, anti-microbial property and cytotoxicity. Barrier properties, biodegradability and fruit shelf life-enhancer capability were also assessed. The outcomes of the testings demonstrated favorable results and confirms the potential of CMG-CA-AA film in food packaging.
期刊介绍：
Polymer Science, Series A is a journal published in collaboration with the Russian Academy of Sciences. Series A includes experimental and theoretical papers and reviews devoted to physicochemical studies of the structure and properties of polymers (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed. Online submission via Internet to the Series A, B, and C is available at http://polymsci.ru.
