The food is packaged and packed with the aim of being transported and stored. That is, not only is it a container, but “the container must protect what it sells and sell what it protects. From the business perspective, the appearance of packaging is particularly important because it identifies the product in the distribution chain and differentiates it when it reaches the consumer. Next, the most used materials in the food industry are detailed: plastics, glass, metals and wood and its derivatives. Technological advances, such as the incorporation of antioxidants in food packaging, increase the shelf life of food. This system is based on the addition of particles to the packaging materials to prevent the oxidation of nutrients. Citations are important for a journal to get impact factor. Impact factor is a measure reflecting the average number of citations to recent articles published in the journal. The impact of the journal is influenced by impact factor, the journals with high impact factor are considered more important than those with lower ones. To increase the visibility and ease of use of open access scientific and scholarly journals PrimeOA Publications top online publishing journals are indexed in different indexing and archiving services.Reproductive toxicity associated with the use of nanoparticles (NPs) in imaging probes and drug delivery has become a concern, although detailed information on reproductive toxicity of NPs is still limited. At present, most research within reproductive and developmental toxicity of ENP must be categorized as hypothesis generating rather than directed towards risk assessment. Future research ought to address more systematically reproductive and developmental toxicity of nanomaterials. Essential goals of research in reproductive and developmental toxicity of ENP must be to: (1) identify most sensitive end-points; and (2) to deduce general rules as to the relative role of, for example, particle size and surface area, surface chemistry, core material, and route of exposure.
