Starch bioplastic film as an alternative food-packaging material
Journal Title: Journal of Achievements in Materials and Manufacturing Engineering - Year 2016, Vol 75, Issue 2
Abstract
Purpose: To synthesize bioplastics on a small scale from starch available in potato and tostudy the characteristics of the same when pectin is blended with it.Design/methodology/approach: The bioplastics are fabricated manually using starchextracted from potato and glycerol. Pectin was blended to this combination to synthesizeanother set of bioplastic films. The characterization of the obtained films were done by FTIRspectroscopy, SEM analysis, water solubility test, water absorption test and biodegradabilitytest.Findings: The synthesized films were found to be physically similar to the commerciallyavailable films. However on further study, it was found that the former could not provideadequate strength as compared to the latter though the former could still be used for lightduty purposes. The advantage of the former over the latter was that it was found to bedegradable.Research limitations/implications: Environment-friendly manufacture of the films on alarge scale is yet to be studied upon. Economic and eco-friendly methods to improve thetensile strength of the bioplastics to bring it at par with the commercial plastic films are tobe found out.Practical implications: The starch and starch-pectin blend films were found to bewater soluble. However, they were also found to absorb water which could be implied as adisadvantage. The main objective of biodegradability was achieved.Originality/value: Though researches are going on in the field of biodegradable films, theaddition of pectin to starch to improve the characteristics of degradable films is an areawhere more research has to be done. This paper inculcates the study of adding pectin tostarch and the resulting changes in the characteristics of the starch film.
