“…In group D, precipitated and bedding nanosilver layer was visible under D3. The reason for this is that the structure of chitin itself has been changed by the composite reaction, so that the nanosilver is effectively attached to it, which is consistent with the structure observed by Gopi and Sahraee using scanning electron microscopy [11,12].the average contact angle (θ) of Control is 75.8±11.3°,A is 79.3 ±11.9°,D is 85.6±12.5°, the difference was not statistically significant (P>0.05). all of them are hydrophilic, indicating that the Preparation has not changed the characteristics of the material itself.…”

Abstract. This study aims to prepare an eco-friendly dressing using Chitin derived membrane with Nanosilver included for anti-bacterial purpose,and also divided into five groups.Group Control was Chitin and Group A was Chitin+dopamine gule (methods for mussel-inspired adhesion of Nanosilver) , respectively, at 0.5mmol/L, 1mmol/L, 2mmol/L (Namely group B, C and D). We found Nanosilver spherical particles formed on chitin dressing. The contact angle test shows that the material was still hydrophilic after processing. Cell staining showed no obvious toxicity in each group.On day 7, the healing rates are 35.2 %, 45.8 %, 56.7 %, 67.9 % and 73.8% in Group Control, A, B, C and D, respectively.The wound healing rate is higher in the C and D groups than these in the other three groups (P <0.05). Similarly, the lengths of the new epithelialm were 618.5 μm, 703.7 μm, 810.2 μm, 879.4 μm and 951.0 μm. in the five groups, respectively. These in group C and D were higher than those in the other three groups (P <0.05).

“…Therefore, net gelatin films did not possess proper moisture barrier property for food packaging. Also, former studies have shown that net gelatin films did not have a high water vapor barrier property (Sahraee et al, ). Comparison of gelatin films containing N‐chitin and N‐ZnO with net gelatin films as a packaging film showed that GN had preserved MC of cakes better than net gelatin films.…”

“…Recently, researchers have studied effect of different nanoparticles on biodegradable films properties (Marvizadeh et al, ; Nafchi, Nassiri, Sheibani, Ariffin, & Karim, ). In this case, nano chitin (N‐chitin) is one of the compatible nanoparticles with carbohydrate and protein‐based polymers that not only can improve physical properties of films, but also can add antimicrobial properties to biopolymer (Sahraee, Milani, Ghanbarzadeh, & Hamishehkar, ). On the other hand, metal oxide nanoparticles such as nano ZnO (N‐ZnO), TiO 2 , MgO, and CaO are interested in their high stability to temperature of process, diffusivity from packaging to food, being safe for animals and human and antimicrobial properties (Nafchi, Moradpour, Saeidi, & Alias, ; Shankar, Teng, Li, & Rhim, ).…”

This research extends the effect of packaging with bovine gelatin, gelatin nanocomposite (GN), gelatin emulsion (GE), two layers gelatin nanocomposite and gelatin emulsion (GNE), and polyethylene (PE) films on sponge cake properties during storage at 25°C and 55 ± 2% RH. In this regard, water vapor permeability (WVP) and oxygen permeability (OP) of films were compared. Then, moisture content, acidity, peroxide value, texture profile, organoleptic properties, and fungal growth of packed cakes were determined. Results showed that the addition of nanoparticles could reduce the water vapor permeability from 9.680 ± 0.460 × 10–10 (g m/sm‐2Pa‐1) for net gelatin film to 6.067 ± 0.337 × 10–10 (g m/sm−2 Pa−1) for gelatin nanocomposite film and oxygen permeability from 39.262 (cm3μm/ m2dkPa) for net gelatin film to 29.645 (cm3μm m−2 dkPa) for nanocomposite film. However, GNE films had the highest barrier properties. Results of acidity and peroxide values of cakes admitted the sufficiency of GNE films for sponge cakes packaging. In addition, antifungal properties of nanoparticles led to less fungal growth on cakes packed in GNE films. The cakes packed in GNE films own more organoleptic and texture acceptability than the ones packed in other films. Generally, according to the results GNE films are acceptable for packaging of sponge cakes which contain no preservative because this packaging can prevent fungal growth for a longer time and even more can maintain the cake chemical and organoleptic quality.

“…Meanwhile, the tomatoes coated with quinoa protein/ chitosan edible film showed a significant decrease in B. cinerea growth after 7 days at 5 °C (Robledo et al, 2018). Besides chitosan, increasing the concentration of chitin nanoparticles from 0 to 5% also significantly enhanced the anti-fungal properties of the gelatin-based nanocomposite films against Aspergillus niger (Sahraee et al, 2017). Meanwhile the nanocomposite films with added chitin nano-whiskers/chitin nanofibrils exhibited strong antimicrobial activity against gram-positive Listeria monocytogenes and but not against gram-negative Escherichia coli (Qin et al, 2016;Shankar et al, 2015).…”

The world fisheries resources have exceeded 160 million tons in recent years. However, every year a considerable amount of total catch is discarded as by-catch or as processing leftovers, and that includes trimmings, fins, frames, heads, skin, viscera and among others. In addition, a large quantity of processing by-products is accumulated as shells of crustaceans and shellfish from marine bioprocessing plants. Recognition of the limited marine resources and the increasing environmental pollution has emphasized the need for better utilization of the by-products. Marine by-products contain valuable protein and lipid fractions, minerals, enzymes as well as many other components. The major fraction of by-products are used for feed production-in making fish meal/oil, but this has low profitability. However, there are many ways in which the fish and shellfish waste could be better utilized, including the production of novel food ingredients, nutraceuticals, pharmaceuticals, biomedical materials, fine chemicals, and other value-added products. In recent times, much research is conducted in order to explore the possible uses of different by-products. This contribution primarily covers the characteristics and utilization of the main ingredients such as protein, lipid, chitin and its derivatives, enzymes, carotenoids, and minerals originating from marine by-products.
