the starch based films have some disadvantages such as weak mechanical and poor water barrier properties that restrict their applications in food packaging. in the present research, the polyvinyl alcohol (povh), as a compatible polymer, and montmorillonite (mmt) nanoclay, as a nanofiller, were added to plasticized starch film (ps) to improve its properties and also to produce ps-mmt-pvoh nanoco...

The effects of zinc oxide nanorod on the barrier, sorption isotherm and antibacterial properties of tapioca starch/bovine gelatin Bionanocomposite films were investigated. The nanorod-rich ZnO (ZnO-N) was homogenized by sonication and incorporated into tapioca starch/bovine gelatin solutions at different concentrations (e.g. 0.5, 2, and 3.5% w/w dried solid). Incorporation of 3.5% of nanopartic...

Essential oils (EOs) derived from plants are rich sources of volatile terpenoids and phenolic compounds. Such compounds have the potential to inactivate pathogenic bacteria on contact and in the vapor phase. Edible films made from fruits or vegetables containing EOs can be used commercially to protect food against contamination by pathogenic bacteria. EOs from cinnamon, allspice, and clove bud ...

Photocuring is a crosslinking process, widely employed to produce polymers in the form of film. As it an environmentally friendly particularly interesting for preparation sustainable materials and composites. In this work, composite self-standing films were obtained combining microfibrillated cellulose (MFC) photocured matrices. To understand influence polarity surface tension matrix on propert...

Films based on polysaccharides and proteins have been widely studied as possible substitutes for food packaging from fossil sources. However, its notorious sensitivity to water is still one of the primary drawbacks. In this study, sodium alginate (SA) hydrolyzed collagen (HC) blend films containing SiO 2 nanoparticles were prepared reduce sensitivity. The behavior these regarding vapor sorption...
