“…Qin and Zhang [186] produced chitosan and montmorillonite (MMT) active films enriched with pomegranate-rind ethanol extract presenting DPPH radical scavenging activity that was not affected by the addition of MMT. Other recent works have reported the developments of films with antioxidant activities, such as films made of arrowroot starch and blackberry particles [177]; fish gelatin or soy protein isolate with mango kernel ethanolic extract [176]; chitosan and Herba Lophatheri extract [178]; and chitosan or starch, containing aqueous thyme extract [175].…”

Antioxidants of Natural Plant Origins: From Sources to Food Industry Applications

In recent years, great interest has been focused on using natural antioxidants in food products, due to studies indicating possible adverse effects that may be related to the consumption of synthetic antioxidants. A variety of plant materials are known to be natural sources of antioxidants, such as herbs, spices, seeds, fruits and vegetables. The interest in these natural components is not only due to their biological value, but also to their economic impact, as most of them may be extracted from food by-products and under-exploited plant species. This article provides an overview of current knowledge on natural antioxidants: their sources, extraction methods and stabilization processes. In addition, recent studies on their applications in the food industry are also addressed; namely, as preservatives in different food products and in active films for packaging purposes and edible coatings.

“…However, color difference was only significant (p < 0.05) for films obtained from commercial high molecular weight chitosan, and the *∆E value obtained is considered as a perceptible color change. These color variations may be attributed to the concentration and type of components used, such as added plasticizer, chitosan molecular weight, deacetylation degree and films storage conditions [32][33][34]. In the practical sense, it can be indicated that CFMl, CFMm and CFMh film presented a light-yellow coloration and that the CFBM films were colorless (Figure 1).…”

High molecular weight chitosan (≈322 kDa) was obtained from chitin isolated from Brachystola magna (Girard) to produced biodegradable films. Their physicochemical, mechanical and water vapor permeability (WVP) properties were compared against commercial chitosan films with different molecular weights. Brachystola magna chitosan films (CFBM) exhibited similar physicochemical and mechanical characteristics to those of commercial chitosans. The CFBM films presented lower WVP values (10.01 × 10−11 g/m s Pa) than commercial chitosans films (from 16.06 × 10−11 to 64.30 × 10−11 g/m s Pa). Frankfurt-type sausages were covered with chitosan films and stored in refrigerated conditions (4 °C). Their quality attributes (color, weight loss, pH, moisture, texture and lipid oxidation) were evaluated at 0, 5, 10, 15 and 20 days. Sausages covered with CFMB films presented the lowest weight loss (from 1.24 to 2.38%). A higher increase in hardness (from 22.32 to 30.63 N) was observed in sausages covered with CFMB films. Compared with other films and the control (uncovered sausages), CFMB films delay pH reduction. Moreover, this film presents the lower lipid oxidation level (0.10 malonaldehyde mg/sample kg). Thus, chitosan of B. magna could be a good alternative as packaging material for meat products with high-fat content.

“…Extensive work has been done using chitosan films, [110][111][112][113][114] which exist in partially crystalline to amorphous states. Chitosan films formed from acetic acid solutions exhibit higher tensile strengths than those prepared with lactic acid, and the mechanical properties of the polymer improve with time and are greater for higher molecular weight chitosan.…”

Extensive research has been conducted on a variety of processes for abating the increasing CO 2 emissions which have been causing adverse effects on the environment. Among these, gas separation membranes have the potential to overcome a number of limitations of existing technologies by reducing the cost of operations and providing an efficient, compact module which can be employed for separating CO 2 from natural gas and post-combustion flue gas streams. Recently, chitosan and its derivatives have proven their ability to form CO 2 -selective facilitated transport membranes through the utilization of the amino group fixed site carriers present in the polymer. Later, the performance of chitosan membrane can be substantially improved by carrier enrichment. This review aims to cover the structure-property relations of chitosan and its film-forming derivatives, with a brief discussion of the advantages and challenges in using these polymers.
