食品包装安全卫生已受到越来越广泛的重视。2005年1至10月,欧盟向我国通报了54起食品包装及接触材料的安全卫生问题。2005年7月1日,欧委会健康和消费者保护总司司长马德林专门就我国出口欧盟与食品接触材料频繁被检出安全卫生问题致函我国驻欧盟大使,提出如果中方不在7月底前采取有效措施,将对中国的此类产品采取进一步措施。食品包装及接触材料已经成为发达国家设立技术壁垒的新领域。近年来,欧盟、美国、日本等对直接与食品接触的包装及包装材料都制定了详细的法规。如FDA长期以来遵循的美国联邦法规,详细规定了各种与食品直接或间接接触的包装材料及其中所使用的各项物质的要求。欧盟在2004年新拟定的草案“食品接触物质超级指令”则进一步综合了过去所有与食品接触物质相关的旧法规,使其成为欧盟对食品包装材料最主要而且最具影响力的新法规。  相似文献

Intelligent food packaging system exhibits enhanced communication function by providing dynamic product information to various stakeholders (e.g., consumers, retailers, distributors) in the supply chain. One example of intelligent packaging involves the use of colorimetric indicators, which when subjected to external stimuli (e.g., moisture, gas/vapor, electromagnetic radiation, temperature), display discernable color changes that can be correlated with real-time changes in product quality. This type of interactive packaging system allows continuous monitoring of product freshness during transportation, distribution, storage, and marketing phases. This review summarizes the colorimetric indicator technologies for intelligent packaging systems, emphasizing on the types of indicator dyes, preparation methods, applications in different food products, and future considerations. Both food and nonfood indicator materials integrated into various carriers (e.g., paper-based substrates, polymer films, electrospun fibers, and nanoparticles) with material properties optimized for specific applications are discussed, targeting perishable products, such as fresh meat and fishery products. Colorimetric indicators can supplement the traditional “Best Before” date label by providing real-time product quality information to the consumers and retailers, thereby not only ensuring product safety, but also promising in reducing food waste. Successful scale-up of these intelligent packaging technologies to the industrial level must consider issues related to regulatory approval, consumer acceptance, cost-effectiveness, and product compatibility.  相似文献

Due to increased demands for greater stringency in relation to hygiene and safety issues associated with fresh food products, coupled with ever-increasing demands by retailers for cost-effective extensions to product shelf-lives and the requirement to meet consumer expectations in relation to convenience and quality, the food packaging industry has rapidly developed to meet and satisfy expectations. One of the areas of research that has shown promise, and had success, is modified atmosphere packaging (MAP). The success of MAP-fresh meat depends on many factors including good initial product quality, good hygiene from the source plants, correct packaging material selection, the appropriate gas mix for the product, reliable packaging equipment, and maintenance of controlled temperatures and humidity levels. Advances in plastic materials and equipment have propelled advances in MAP, but other technological and logistical considerations are needed for successful MAP systems for raw chilled meat. Although several parameters critical for the quality of MA packed meat have been studied and each found to be crucial, understanding of the interactions between the parameters is needed. This review was undertaken to present the most comprehensive and current overview of the widely available, scattered information about the various integrated critical factors responsible for the quality and shelf life of MA packed meat with an interest to stimulate further research to optimize different quality parameters.  相似文献

Antimicrobial food packaging in meat industry   总被引:5,自引:0,他引:5  
Antimicrobial packaging, an active packaging concept, can be considered an extremely challenging technology that could have a significant impact on shelf-life extension and food safety of meat and meat products. Use of antimicrobial substances can control the microbial population and target specific microorganisms to provide higher safety and quality products. Many classes of antimicrobial compounds have been evaluated in film structures, both synthetic polymers and edible films: organic acids and their salts, enzymes, bacteriocins, and miscellaneous compounds such as triclosan, silver zeolites, and fungicides. The characteristics of some antimicrobial packaging systems are reviewed in this article. The regulatory status of antimicrobial packaging in EU is also examined.  相似文献

Interest in the use of active and intelligent packaging systems for meat and meat products has increased in recent years. Active packaging refers to the incorporation of additives into packaging systems with the aim of maintaining or extending meat product quality and shelf-life. Active packaging systems discussed include oxygen scavengers, carbon dioxide scavengers and emitters, moisture control agents and anti-microbial packaging technologies. Intelligent packaging systems are those that monitor the condition of packaged foods to give information regarding the quality of the packaged food during transport and storage. The potential of sensor technologies, indicators (including integrity, freshness and time-temperature (TTI) indicators) and radio frequency identification (RFID) are evaluated for potential use in meat and meat products. Recognition of the benefits of active and intelligent packaging technologies by the food industry, development of economically viable packaging systems and increased consumer acceptance is necessary for commercial realisation of these packaging technologies.  相似文献

Extension of the shelf-life of meat and poultry products is one of the technology needs to meet the demands of consumers. In this respect, increasing attention is put on packaging techniques. Modified atmosphere packaging (MAP) and vacuum packaging (VP) are recent innovations that have been gaining importance as preservation techniques to improve the shelf-life of meat and poultry. MAP provides alterations of atmospheric gas concentrations in the pack. Controlled atmosphere (CA) packaging is also MAP, wherein the selected atmospheric concentration of gas is actively maintained throughout the storage period. In VP, air is completely removed. The three principal gases used in MAP are carbon dioxide (to inhibit bacteria and moulds), nitrogen (to avoid oxidation of fats and pack collapse), and oxygen (to prevent anaerobic growth). Retention of meat color is better in MAP than in VP. However, color is regained when meat is removed from VP packets and exposed to air. Microbial profiles of MAP- and VP-meat do not differ significantly. MAP offers several unique advantages for retaining the desirable market quality of products. The safety of MAP meat is still a concern under temperature abuse conditions but it can be improved by coupling with hurdle technology and proper preservation systems. Active packaging is a significant area of advancement of MAP technology to further improve the safety of meat and poultry products. This contribution critically reviews the existing knowledge on MAP and VP of meat and poultry in order to broaden our understanding of the subject and to suggest further areas of research to effectively use these technologies for marketing safe meat and poultry products.  相似文献

Although ω‐3 intake has been associated with numerous health benefits, its addition to certain food matrices, and in particular meat products, may involve various technological barriers influencing the final quality of the products. Lipid oxidation must be highlighted due to the modification of both the sensory characteristics and the shelf‐life of meat products. In order to reduce the impact of chemical changes and promote oxidative stability, the use of natural antioxidants has gained ground owing to the health and safety advantages linked to its effectiveness at reducing lipid oxidation. Many natural compounds have also been successfully tested in animal feed, in order to protect the raw meat materials and reduce the risk of lipid oxidation in processed products. This review aims to address the challenges and advantages of the incorporation of ω‐3 fatty acids in raw meat materials and processed meat products, and to describe the use of different compounds to enhance lipid oxidative stability. © 2015 Society of Chemical Industry  相似文献

BackgroundIn recent years, there has been growing consumer demand for the minimally processed and chemical additives free Ready-To-Eat (RTE) healthier meat products. On the other hand processed and RTE meat products have been notified as the primary cause for food borne outbreaks in different countries that commonly associated with emerging pathogens such as Salmonella, Listeria monocytogenes and Escherichia coli species.Scope and approachHigh pressure processing (HPP) has been renewed as a best non-thermal intervention for extending the shelf-life and safety of RTE meat products without altering the sensory and nutritional properties. Meat products are complex medium with different physical and chemical compositions that influence the lethality of the microorganisms during HPP. Using high pressure levels (above 600 MPa) for complete sterility of meat products may not be economically feasible more over it may negatively affect the product quality characteristics. The present review aimed to explore the recent research investigations addressed the multi hurdle approaches to increase the effectiveness of HPP at lower processing levels in order to reduce the processing costs and to improve the safety and quality of processed meat products.Key findings and conclusionsThe combination of natural antimicrobials (plant bioactive compounds and bacteriocins) and antioxidants (plant phenolic compounds) as additional hurdles through different mechanisms (active and intelligent packaging) during HPP can definitely be an effective and innovative intervention in ensuring the complete safety of processed meat products. Moreover, the development of low salt meat products with optimum quality attributes can be highly possible through HPP technology.  相似文献
