The use of edible film from kitosan with CMC as a plasticizer as packaging fish burger

Abstract

The aim of this research was to study the capability of CMC in improving the characteristics of edible film made from kitosan, as well as to see the ability of edible film in maintaining the shelf life of fish burger product at room temperature. Three various concentration of CMC was used, namely 0.1%, 0.3% and 0.5%. The results of kitosan edible film characterization from the three concentrations of CMC showed that the concentration of 0.1% was the best concentration as a plasticizer, with thickness 0.19 mm, water vapor transmission rate 50.8 ml/m2/day, the tensile strength 24.2 kgf/cm2 and percentage elongation 18.1%. The shelf life of fish burger wrapped with kitosan edible film with 0,1% CMC was longer (two days) than burger without edible film at room temperature, indicated by the some parameters such as water content, protein content, fat content, ash content, water activity and TPC (total plate count) and organoleptic value.
