Eight samples of alginate were extracted per procedure. Nuclear magnetic resonance spectroscopy (NMR) was used to determine the mannuronic acid/guluronic acid (M/G) ratios of alginates of produced alginates, and gel permeation chromatography (GPC) was used to identify their molecular weights. Infrared spectroscopy (IR) was used to determine the purity of produced alginates and to determine the presence of unwanted polysaccharide impurities. Based on the properties of produced alginate and the sustainability of the extraction processes, one was selected to be used in further kelp alginate characterization. Understanding the properties of alginate produced by local kelp allows bioplastic manufacturers to tailor the plastics they produce based on kelp species and growth environment.enBioplasticalginatekelpsustainabilitygreen chemistryindustrial chemistryprocess chemistryPoster
