“…MC brings high deformability to the blend due to its elongation at break value of 12.7%, vs. 3.9% for CH. The addition of CH has been seen to increase the solubility of the films in water (Mura et al 2011) and decrease the WVP of the composite (García et al 2009a;Khan et al 2011). In some studies, the WVP of pure MC and CH have been essentially the same; 7.55  0.60·10 -11 g·m/m 2 ·s·Pa and 7.24  0.81·10 -11 g·m/m 2 ·s·Pa, respectively (Pinotti et al 2007).…”

“…MC is soluble in cold water when the degree of substitution is within the range 1.4 to 2.0 (Sjöström 1993). It is non-toxic and forms continuous, flexible, transparent, tasteless films that have good oxygen barrier properties (Mura et al 2011), but it is a poor barrier against water vapor. MC can be used as an edible film or coating, and as a component to modify the mechanical and barrier properties of layered or blended composites for packaging.…”

Cellulose derivatives, i.e. cellulose functionalized in a solvent state with various side groups, are an important source of biomaterials for food packaging. This review considers the following materials: i) cellophane, ii) cellulose acetate, iii) methylcellulose, and iv) carboxymethylcellulose. Mechanical and barrier properties are important for freestanding packaging films as well as for coatings. The potential of the selected cellulose derivatives and cellophane is thus examined from the viewpoint of their tensile properties as well as their moisture and oxygen barrier properties. The capacity of microcrystalline cellulose and nano-sized celluloses to reinforce the films and to help impede gas diffusion is examined for microfibrillar celluloses, nanocrystalline celluloses, and whiskers. Very good oxygen barrier properties have been reported for cellophane. Nanocellulose fillers have regularly been shown to enhance the tensile properties of several cellulose derivatives, but the effects on the water vapor permeability (WVP) have been studied less often.

“…As an alternative to plastic materials, Mura et al reported the excellent improvement in the mechanical properties of a nanostructured film composed of chitosan, methylcellulose and silica nanoparticles which may replace plastic for packaging foods thereby reducing the environmental pollution by plastics [110]. Another interesting work done by de Moura et al show the application of chitosan nanoparticles-carboxymethylcellulose films [111].…”

The environmental sustainability and use of environmentally acceptable biomaterials are major areas of scientific and industrial research. In recent times, identification and application of suitable biopolymers instead of petroleum derived conventional polymers are gaining more attention. Chitosan and chitosan derived nanoparticles and nanocomposites are very promising due to their versatile properties and have found applications in various areas such as biomedical, foods, food packaging and personal care. Many studies suggest that chitosan nanoparticles and their derivatives are one of the best barrier and film coating materials for preserving the quality of foods and for delivering skin care products, mainly due to their biodegradability and anti-microbial properties. The present review gives insight on the progress made in the application of chitosan nanoparticles specifically in foods and food packaging, personal care products and in biomedical industry. Future studies shall address establishment of industrial scale up of chitosan nanoparticles, safety and quality aspects of these chitosan derived products for human use.

“…For example, the possible role of chitosan NPs (Corradini et al, 2010;Mura et al, 2011a) and of kaolinbased nanolayers was assessed for slow release of NPK fertiliser, but further investigation is still needed (Ghormade et al, 2010).…”

With the increase in the world population and the demand for food, new agricultural practices have been developed to improve food production through the use of more effective pesticides and fertilisers. These technologies can lead to an uncontrolled release of undesired substances into the environment, with the potential to contaminate soil and groundwater. Today, nanotechnology represents a promising approach to improve agricultural production and remediate polluted sites. This paper reviews the recent applications of nanotechnologies in agro-environmental studies with particular attention to the fate of nanomaterials once introduced in water and soil, to the advantages of their use and their possible toxicology. Findings show that the use of nanomaterials can improve the quality of the environment and help detect and remediate polluted sites. Only a small number of nanomaterials demonstrated potential toxic effects. These are discussed in detail.
