Comprehensive review on application of edible film on meat and meat products: An eco-friendly approach

The functions of packaging materials are to prevent moisture loss, drip, reduce lipid oxidation, improve some of their sensorial properties (color, taste and smell) and provide microbial stability of foods. Edible films can be made from protein, polysaccharides and lipids or by combination of any of these to form a composite film. Nanocomposites are composite films made by incorporation of nanoparticles. Edible packaging and coating of the meat and meat products enhances the self-life by the incorporation of the active compound (such as antimicrobial and antioxidant compound) in to the packaging matrix. Incorporation of the some ingredients in the matrix may also improve the nutritional as well as sensory attributes of the packed products. Edible packaging material also reduces environmental pollution by overcoming the burden degradation as edible films are biodegradable and thus eco-friendly.

Development of Antioxidant Packaging Material by Applying Corn‐Zein to LLDPE Film in Combination with Phenolic Compounds

Abstract: Functional active packaging materials were successfully developed by incorporating antioxidant agents into corn‐zein‐laminated linear low‐density polyethylene (LLDPE) film. The minimum effective concentrations of the active compounds (for example, thymol, carvacrol, eugenol) were determined and these compounds were then laminated into LLDPE films to develop corn‐zein‐laminated films with antioxidant agents. The release rate of antioxidant agents in gas and liquid media were determined along with the mechanical and water barrier properties of the films containing these compounds. Tensile strength and percentage elongation at break were reduced in the corn‐zein‐laminated LLDPE films when compared to typical LLDPE film. Furthermore, the ability of the corn‐zein‐laminated films to repel moisture decreased by approximately 12.2%, but was improved by incorporating hydrophobic antioxidant compounds in the corn‐zein layer. Examination of release kinetics in the gas and liquid phases verified that antioxidants were effectively released from the films and inhibited oxidation during testing. Finally, the films were used for fresh ground beef packaging, and effectively inhibited lipid oxidation and had a positive effect on the color stability of beef patties during storage. These results indicate that the developed antioxidant films are a novel active packaging material that can be effectively implemented by the food industry to improve the quality and safety of foods. Practical Application: Zein protein, a by‐product of corn processing industry, was laminated into plastic films in combination with natural phenolic compounds to develop antioxidant packaging films. The films demonstrated their efficient release patterns of antioxidant compounds, which are suitable for packaging applications and food protection.

超声与光催化作用对大豆蛋白/TiO_2复合膜抗菌特性的影响

采用光催化/超声预处理,结合涂膜法制备大豆蛋白/TiO_2纳米复合膜,分析光催化和超声预处理以及膜中TiO_2含量对复合膜性质的影响。当TiO_2含量低于2%时,扫描电子显微镜观察发现TiO_2纳米颗粒均匀地分散在大豆蛋白基质中,从而有效地改善复合膜的机械性能,降低膜的溶胀变形程度,提高膜的热稳定性,增强复合膜的抗菌活性。荧光光谱分析、红外光谱和X-射线衍射分析证实了大豆蛋白和纳米颗粒间以氢键为主要作用力,且光催化可进一步增强TiO_2颗粒与大豆蛋白链间交联作用,因而光催化复合膜的机械性能、热稳定性和抗菌活性均高于超声复合膜。但当TiO_2含量过高(2%)会加剧TiO_2间的自聚,导致复合膜机械性能下降、溶胀变形程度增大及荧光淬灭。因此光催化大豆蛋白/TiO_2纳米复合膜有望成为新型绿色抗菌包装材料。     

Antimicrobial activity of biodegradable polysaccharide and protein-based films containing active agents

Significant interest has emerged in the introduction of food packaging materials manufactured from biodegradable polymers that have the potential to reduce the environmental impacts associated with conventional packaging materials. Current technologies in active packaging enable effective antimicrobial (AM) packaging films to be prepared from biodegradable materials that have been modified and/or blended with different compatible materials and/or plasticisers. A wide range of AM films prepared from modified biodegradable materials have the potential to be used for packaging of various food products. This review examines biodegradable polymers derived from polysaccharides and protein-based materials for their potential use in packaging systems designed for the protection of food products from microbial contamination. A comprehensive table that systematically analyses and categorizes much of the current literature in this area is included in the review.
