Preparation of konjac glucomannan based films reinforced with nanoparticles and its effect on cherry tomatoes preservation

• NZ promoted the entanglement of KGM chains in film-forming solution. The nanoparticles changed molecular network structure based films. KNZ film showed best properties due to good compatibility between and KGM. packaging extended shelf life cherry tomatoes. Present study aims investigate effect (zein nanoparticles, nanocellulose, nano-TiO 2 , nano-SiO ) incorporation on rheological solutions physicochemical konjac glucomannan (KGM) films, evaluate KGM/nanoparticles blend tomatoes preservation. results that exhibited shear-thinning behavior, KGM/zein nanoparticle solution lowest crossover frequency value storage (G?) loss (G") moduli enhanced interaction entanglement. were dispersed homogeneously continuous matrix had with KGM, thereby improving (KNZ) properties, such as smoother surface denser cross-section, highest glass transition temperature elongation at break, well moisture oxygen barrier. In comparison control polyethylene packaging, lower weight firmness reduction, relatively stable content total soluble solids, vitamin C pH during up 10 days 26 °C. suggested high potential for application
