          Abstract

          This paper reports the incorporation of SiO 2–ZnO nanoparticles (NPs) into semi-refined iota carrageenan-based (SRIC) film as active food packaging. The dispersion of the nanoparticles was performed using a bead milling method and the films were prepared using the solution casting method. The incorporation of SiO 2–ZnO NPs into SRIC films aims to provide multifunctional food packaging with enhanced water vapor barrier properties, UV-screening, and antimicrobial activity. The effect of the incorporation of SiO 2 NPs, ZnO NPs, and the mixtures of SiO 2–ZnO NPs varied in SiO 2/ZnO ratios (SiO 2–ZnO 1:1, 1:2, and 1:3) were investigated. The results showed that the tensile strength, water vapor barrier performance, UV-screening, and antimicrobial activity of the SRIC film were increased by the addition of either SiO 2 or ZnO NPs alone. Interestingly, when the mixtures of SiO 2–ZnO were incorporated, more significant improvement was observed. Also, the bio-degradability and solubility of all the SRIC films were confirmed. It was concluded that the SiO 2–ZnO NPs incorporated into SRIC film provided multifunctional activities and acted as a promising active food packaging material.

            Zinc Oxide—From Synthesis to Application: A Review

            Agnieszka Kołodziejczak-Radzimska, Teofil Jesionowski (2014)
            Zinc oxide can be called a multifunctional material thanks to its unique physical and chemical properties. The first part of this paper presents the most important methods of preparation of ZnO divided into metallurgical and chemical methods. The mechanochemical process, controlled precipitation, sol-gel method, solvothermal and hydrothermal method, method using emulsion and microemulsion enviroment and other methods of obtaining zinc oxide were classified as chemical methods. In the next part of this review, the modification methods of ZnO were characterized. The modification with organic (carboxylic acid, silanes) and inroganic (metal oxides) compounds, and polymer matrices were mainly described. Finally, we present possible applications in various branches of industry: rubber, pharmaceutical, cosmetics, textile, electronic and electrotechnology, photocatalysis were introduced. This review provides useful information for specialist dealings with zinc oxide.

              Bionanocomposites materials for food packaging applications: Concepts and future outlook

              Samah M El-Sayed, Ahmed Youssef (2018)
              Bionanocomposites materials open a chance for the usage of novel, high performance, lightweight, and ecofriendly composite materials making them take place the traditional non-biodegradable plastic packaging materials. Biopolymers like polysaccharides such as chitosan (CS), carboxymethyl cellulose (CMC), starch and cellophane could be used to resolve environmental hazards owing to their biodegradability and non-toxicity. In addition these advantages, polysaccharides have some disadvantages for example poor mechanical properties and low resistance to water. Therefore, nanomaterials are used to improve the thermal, mechanical and gas barrier properties without hindering their biodegradable and non-toxic characters. Furthermore, the most favorable nanomaterials are layered silicate nanoclays for example montmorillonite (MMT) and kaolinite, zinc oxide (ZnO-NPs), titanium dioxide (TiO2-NPs), and silver nanoparticles (Ag-NPs). In packaging application, the improvement of barrier properties of prepared films against oxygen, carbon dioxide, flavor compounds diffusion through the packaging films. Wide varieties of nanomaterials are suitable to offer smart and/or intelligent properties for food packaging materials, as demonstrated by oxygen scavenging capability, antimicrobial activity, and sign of the level of exposure to various harmful features for instance oxygen levels or insufficient temperatures. The compatibility between nanomaterials and polymers matrix consider the most challenge for the preparation of bionanocomposites as well as getting whole distribution of nanoparticles into the polymer matrix. We keen in this review the development of packaging materials performance and their mechanical, degradability and thermal stability as well as antibacterial activity for utilization of bionanocomposites in different packaging application is considered.
