Abstract
Nori is an edible seaweed product and is known to form a sheet. This study involves the production of nori, from a mixture of Gracilaria and Ulva Lactuca seaweeds, at a ratio of 1:1. Besides, glycerol was adopted as a plasticizing biopolymer for food packaging materials. This study, therefore, aims to evaluate the characteristics of nori, following the addition of glycerol concentration (0.4; 0.6; 0.8; 1.0 percent) as a plasticizer on the nori/edible seaweed. The parameters evaluated include elongation percentage, tensile strength, WVTR, thickness, and water content. Moreover, treatments with 0.8 percent glycerol concentration generated edible seaweed films with the following characteristics: elongation percentage of 12.15%, while the tensile strength, WVTR, thickness, and water content were 2,67 M.Pa, 2268 gr/m2 day, 328.93 μm, and 12,75 %, respectively.
