TiO2 has a very useful photocatalytic ability. In this study TiO2 is used to be a component of nanocomposite as decomposers of organic compounds in active packaging. Another component used is nanoselulose. Nanoselulose is the world's most biopolymer, biodegradable and nontoxic. Nanoselulose has oxygen barrier properties so it is suitable for food packaging applications. The nanocomposite matrix used to combine nanoparticles and nanocellulose is a PMMA polymer. PMMA is chosen because it is one of the thermoplast polymers that have good optical and mechanical properties. <br /> <br /> <br /> <br /> <br /> In this research, TEM observation was done to see morphology and size of nanocellulose, the result was nanocellulose has nano rod shape with size <100 nm. The XRD characterization was also performed to determine the effect of the calcination temperature on the TiO2 phase. The result was the higher temperature given, anatase phase will turn into the rutile phase. UV-Vis was performed to see transparency and absorbance of nanocomposites, the result was nanocomposites with the most nanoselulose have the lowest transparency <br /> <br /> <br /> <br /> <br /> and the highest absorbance, while the nanocomposites with the least nanocellulose have the highest transparency and the lowest absorbance. Fruit <br /> <br /> <br /> <br /> <br /> ripening testing was done to determine the ability of nanocomposite as fruit ripening inhibitor. The results was nanocomposite can inhibit fruit maturation.
