“…TiO 2 -covered thin layers can reduce microbial contamination on the surface of food products. [11] Mihaly Cozmuta et al [12] studied the ability of the packaging of a silver (Ag)/ TiO 2 nanocomposite prepared by the solvent method to increase the durability of bread. Ahari et al [13] examined the microbiological properties of TiO 2 and Ag (1%, 3%, and 5%) nanocomposite coatings on dry sausages.…”

Sol-gel and melt-mixing processes, which are used for the synthesis of lowdensity polyethylene/silver/titanium dioxide nanocomposites, can inactivate pathogens. In the sol-gel method, the nanocomposites were used to treat four selected microorganisms using the disk-diffusion method. In the melt-mixing method, fish coverage films were used to examine the shelf life of fish. TiO 2 along with different concentrations of Ag (0%, 1%, 3%, and 5%) generated the nanocomposites. The maximum inhibition zone diameters (mm) for Staphylococcus aureus, Escherichia coli, Candida albicans, and Aspergillus niger in 3% Ag were measured. It was concluded that applying the LDPE/Ag/TiO 2 nanocomposites produced could be beneficial for inactivation of pathogens. ARTICLE HISTORY

“…AgNPs absorb and decompose ethylene, which may contribute to their effects on extending shelf life of fruits and vegetables [357]. Senescence of the Chinese fruit jujube was retarded by nanocomposite polyethylene film with AgNPs [358], and a coating of Ag nanomaterial prolonged the shelf life of asparagus samples by decreasing microbial growth [359], while TiO 2 powder-coated food packaging film was found to be suitable for use with freshly cut produce due to its ability to inactivate E. coli [360].…”

Nanoagrochemicals, such as nanopesticides, nanofertilizers or plant growth stimulating nanosystems, were primarily designed to increase solubility, enhance bioavailability, targeted delivery, controlled release and/or protection against degradation resulting in the reduced amount of applied active ingredients and finally in a decrease of dose-dependent toxicity/burden. This paper is a comprehensive up-to-date review related to the preparation and the biological activity of nanoformulations enabling gradual release of active ingredient into weeds and the body of pests and controlled release of nutrients to plants. The attention is also devoted to the decrease of direct environmental burden and economic benefits due to application of nanoformulations, where less amount of active ingredient is needed to achieve the same biological effect in comparison with bulk. The application of nanotechnology in the areas such as food packaging, food security, encapsulation of nutrients and development of new functional products is analysed. The use of nanoparticles in biosensors for detection of pathogens and contaminants as well as in DNA and gene delivery is discussed as well. Benefits and health risks of nanoagrochemicals are highlighted, and special attention is given to nanoecotoxicology and guidelines and regulatory documents related to the use of nanoformulations in agriculture and food industry.

“…As nanopartículas de TiO 2 são eficazes contra patógenos de origem alimentar, como, S. choleraesuis, V. parahaemolyticus, e L. Monocytogenes sob radiação UV, mas não no escuro [9] . Chawengkijwanich [35] , demonstrou que embalagens de alimentos com filmes de PP revestidos com nanopartículas de TiO 2 inibiram o crescimento de E. coli em alface fresca.…”

AesumoA nanotecnologia tem grande potencial de aplicação na indústria de alimentos. No desenvolvimento de embalagens, pode proporcionar diferentes alternativas, tais como o desenvolvimento de nanopartículas, nanodispersões, nanolaminados, e nanotubos, que, associados aos polímeros, podem fornecer diversas funções. Por exemplo, pela incorporação de nanopartículas com propriedades antimicrobianas; nanosensores capazes de detectar produtos químicos, agentes patogênicos e toxinas em alimentos; nanopartículas bioativas capazes de manter os compostos em condições ideais, até a sua migração para o produto alimentício e nanocompósitos, que melhorem as propriedades de flexibilidade, barreira a gases e umidade e quanto à absorção de irradiação UV dos materiais aos quais são incorporados, assim como a estabilidade frente à temperatura. Este artigo relata algumas aplicações da nanotecnologia em embalagens de alimentos, bem como questões sobre toxicidade e regulamentação relacionadas à possibilidade de migração das nanopartículas para os alimentos; razão pela qual o setor alimentício tem sido cauteloso com a utilização desses materiais. Palavras-chave: toxicidade, regulamentação, nanopartículas, embalagem ativa, embalagem inteligente. AbstractNanotechnology has great application potential in the food industry.

For example, by embedding nanoparticles with antimicrobial properties; nanosensors capable of detecting chemicals products, pathogens and toxins in food; bioactive nanoparticles capable of maintaining compounds at optimal conditions until its migration to the food product and nanocomposites, which improve the properties of flexibility, gas and humidity barrier and UV irradiation absorption of the materials to which are incorporated, as well as stability against temperature. This article reports some applications of nanotechnology in food packaging, as well as questions regarding toxicity and regulations related to the migration of nanoparticles to the food products; reason why the food industry has been cautious with the utilization of these materials.Keywords: toxicity, regulation, nanoparticles, active packaging, intelligent packaging. IntroduçãoAtualmente, grande parte das embalagens utilizadas no setor alimentício é de plástico, produzidas com base em polímeros oriundos do petróleo. Em geral, na comparação com outros materiais como papel, madeira, metais, vidros e cerâmicas, as embalagens plásticas destacam-se pelas vantagens que apresentam quanto às características físico-mecânicas como peso, flexibilidade, resistência mecânica, bem como outras características físico-químicas e biológicas, vinculada à qualidade, saúde e segurança, algumas das quais serão abordadas mais adiante. Em conjunto, essas características além de proporcionarem vantagens significativas no processamento de embalagens e adição de valo...
