The preparation of cellulose nanocomposite film from isolated cellulose of corncobs as food packaging

Abstract

The cellulose nanocomposite as food packaging has been prepared from the isolated cellulose of corncobs waste. The cellulose in corncob powder was isolated through a standard isolation method with various acid and bases by the heating process. As many as 17.4% of cellulose was successfully isolated and characterized via FTIR spectroscopy, TGA and TEM. Furthermore, the isolated cellulose was partially dissolved in DMAC/LiCl 8% and compressed at high temperature to produce the cellulose nanocomposite film. The isolated cellulose showed a similar functional group with the commercial cellulose, indicating the success of the isolation process. SEM analysis was conducted to several all-cellulose nanocomposites with various time of soaking. The best soaking time to perform was 60 min. showing a good result in morphological surface analysis. Moreover, the cellulose nanocomposite film exhibited as a good food packaging material to negate the microbes growth in food.
