“…Previous studies have demonstrated the effectiveness of olive oil addition to reduce the water vapor permeability of chitosan-based biofilms [31]. Olive oil was also used as an active natural additive on sodium alginate [32] and chitosan-based biofilms [33,34], mainly due to the action of hydroxytyrosol and tyrosol compounds [35]. Regarding corn starch-based films, some studies have been recently reported in which compounds extracted from olive oil were selected as active additives [36].…”

Active edible films based on corn starch containing glycerol as a plasticizer and an olive extract obtained from Spanish olive fruit (Olea europaea) by-products (olive extract; OE) at different concentrations (0, 0.05, 0.1 and 0.2 wt%) were prepared by using the casting technique and further solvent-evaporation. OE showed high total phenolic and flavonoids contents and antioxidant activity, which was evaluated by using three different methods: free radical scavenging assay by (1, 1-Dipheny l-2-picrylhydrazyl) DPPH, 2, 2-Azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) ABTS radical inhibition and ferric reducing antioxidant power (FRAP). The incorporation of OE into the corn starch/glycerol matrix underlined the antioxidant potential and antimicrobial effect against E. coli and S. aureus of these novel active films, being noticeable for films added with 0.2 wt% OE. The developed active films showed a clear thermo-oxidative stability improvement with OE incorporation, in particular at 0.2 wt% loading with an increase of around 50 °C in the initial degradation temperature (Tini) and oxidation onset temperature (OOT). The functional properties of control films were also improved with OE addition resulting in a decrease in Young’s modulus, elongation at break, shore D hardness and water vapor permeability. The present work suggested the potential of the developed corn starch-based edible films as low-price and sustainable food packaging systems to prevent the oxidative deterioration of packaged foodstuff while reducing also the generation of olive by-products.

“…Commonly, thermal properties of polymers are studied through differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) [ 110 ]. In food packaging it is very important to quantify these properties with the aim of knowing the thermal stability of the materials that will be part of the food packaging system [ 111 ]. For thermal analysis, integrated DSC and TGA equipment or independent equipment can be used.…”

The call to use biodegradable, eco-friendly materials is urgent. The use of biopolymers as a replacement for the classic petroleum-based materials is increasing. Chitosan and starch have been widely studied with this purpose: to be part of this replacement. The importance of proper physical characterization of these biopolymers is essential for the intended application. This review focuses on characterizations of chitosan and starch, approximately from 2017 to date, in one of their most-used applications: food packaging for chitosan and as an adsorbent agent of pollutants in aqueous medium for starch.

“…The scavenging capacity can be evaluated via 2,2-diphenyl-1-picrylhydrazyl radical (DPPH•) scavenging, hydroxyl radical (•OH) and superoxide radical (•O 2 -) assay methods. Hasan et al 46 studied the antioxidant activity of chitosan films incorporated with edible sugar palm starch (SPS) carrying extra virgin olive oil (EVOO) against DPPH free radical scavenging. They reported that the lowest antioxidant activity, that is, 77.47%, was reached by chitosan-SPS films without the addition of EVOO, while this activity reached upto 87.14% when 5.0% w/w EVOO was added to Chitosan-SPS film.…”

They reported that the chitosan control film showed free radical scavenging activity of 3.7% but incorporating LFE significantly enhanced the free radical scavenging activity of the chitosan films.…”

Being credited with the most extensively studied polysaccharide polymer and promising candidate for versatile applications, chitosan has proved to be a standalone material with loads of diversified properties in various structural forms such as blends and composites. Considering the abundance of this biopolymer and its non-toxic nature, exploiting chitosan offers two-folded benefits – environment friendliness and fabrication as per the need. Alkaline deacetylation of chitin produces chitosan as a polymer that can be tuned to a great extent as per the requirement by altering the degree of deacetylation (DDA) and molecular weight (MW). This biopolymer has been widely investigated for potential application in the food and biomedical fields due to its antimicrobial and antibacterial properties. Chitosan based composite films incorporated with different natural extracts have shown significant enhancement in the physical and biological activities as reported by different studies. The current study reviews recent developments and investigations of chitosan based biocomposite films incorporated with different natural extracts emphasizing on the improvement of physical and biological properties and its applications.
