Consumo de alimentos funcionales: factores determinantes
2019
El concepto de alimento funcional nació en Japón en 1991, y desde entonces ha sido objeto de estudio debido al gran crecimiento de mercado que ha experimentado esta categoría de producto en las últimas décadas (Arai, Osawa, Ohigashi, Yoshikawa, Kaminogawa, Watanabe, . . . Nishino, 2001). En líneas generales, podemos definir que un alimento se considera funcional si se demuestra que ejerce un efecto beneficioso sobre una o más funciones selectivas del organismo, además de sus efectos nutritivos intrínsecos, de modo que mejore el estado de salud y bienestar, reduzca el riesgo de enfermedad, o ambas cosas (Diplock, Agget,Ashwell, Bornet, Fern y Roberfroid, 1999). Ahora bien, el consumidor s…
Food Packaging. Narrazioni semiotiche e branding alimentare
2022
Analysing food packaging means discovering its narratives, the ways in which a culture thinks about it. To analyze how brands speak to consumers through packaging is to delineate the type of consumers that brand is targeting. Packaging is one of the elements of the branding process and is also one of the texts through which a certain culture thinks about and reflects food, dietetics, health, taste, and nutrition.
Che cos'è il packaging
2014
Racchiudere e proteggere, descrivere e raccontare, coinvolgere e consigliare. Da semplici imballaggi, le confezioni dei prodotti si sono via via trasformate in oggetti di senso complessi, in grado di rispondere a molteplici esigenze comunicative, di marketing, logistiche e igieniche. Entrano nelle nostre case, riempiono gli spazi domestici, diventano molto spesso oggetti d'uso quotidiano. Ma che ne è del prodotto contenuto? Il volume illustra il modo in cui il pack lo racconta, lo valorizza, lo traduce, proponendosi come un'unità semiotica sempre nuova. rivolto a studenti di design e comunicazione, professionisti del branding, designer ed esperti di marketing, il testo offre una visione com…
Ethyl hexanoate transfer in paper and plastic food packaging by sorption and permeation experiments
2008
The barrier properties of one treated paper packaging and one standard plastic film (bi-oriented polypropylene, biOPP) were assessed for ethyl hexanoate. Three methods based either on sorption (gravimetry and micro-atmosphere-derived method) or permeation kinetic determination were used in controlled conditions of aroma vapor concentration (107 Pa), temperature (25 degrees C) and relative humidity (about 0 %). Ethyl hexanoate solubility values were on the same range of magnitude for both packaging films in spite of their different nature and composition. Ethyl hexanoate affinity for both films was well predicted by their respective solubility parameters. Solubility values were different acc…
Toward Sustainable PLA-Based Multilayer Complexes with Improved Barrier Properties
2019
Poly(lactic acid) or PLA is currently considered as one of the most promising substitutes of conventional plastics, with low environmental impact, especially for food packaging applications. Nevertheless, some drawbacks, such as high permeability to oxygen, are still limiting its industrial applications. The objective of this study was to highly increase the oxygen barrier performance of PLA without compromising its sustainable nature and following the principles of circular economy perspective. Coproducts coming from mill industries, such as wheat gluten proteins (WG), were used to produce PLA-WG-PLA multilayer complexes with improved barrier performance. Different technologies of industri…
The role of the matrix-filler affinity on morphology and properties of polyethylene/clay and polyethylene/ compatibilizer/clay nanocomposites drawn f…
2009
In this work the structural variations and mechanical performance of polyethylene/clay nanocomposite drawn fibres, also in the presence ofcompatibilizer, such as a commercial maleic anhydride grafted polyethylene, PEgMA, was studied. In the isotropic state both systems show intercalated morphology.After spinning and cold drawing, by adding the nanoparticles, the tensile strength as a function of the draw ratio increases and this rise is more pronounced for the filled compatibilized system. The reduction of the elongation at break, on the contrary, is about the same for all the examined samples. The orientation of the macromolecules, evaluated by measurements of the birefringence and calorim…
Necrobia rufipes (De geer) infestation in pet food packaging and setup of a monitoring trap
2020
Simple Summary Necrobia rufipes (Coleoptera: Cleridae) is an emerging pest of pet food stores. Information on infestation modalities for this pest is absent and specific monitoring tools are missing. In this paper, the adults’ and larvae’s ability to enter into pet food packaging was evaluated. Furthermore, to set up of a monitoring trap behavioral bioassays were carried out: testing two adhesive surfaces, one generally used in mouse glue trap and the other used in cockroach trap, to evaluate their ability in avoiding insects’ escape; screening different molecules, as candidate food attractants: methyl cyclopentenolone, squalene and stearic acid. The results evidenced that N. rufipes enter …
Effect of different packaging methods on the free amino acid profiles of the deep-water rose shrimp (Parapenaeus longirostris) during frozen storage
2022
The composition of free amino acids (FAAs) in seafood products contributes to characterizing their flavor, as well as freshness and quality during storage. Deep-water rose shrimps (Parapenaues longirostris, Lucas, 1846) (DWRS) are being increasingly harvested in the Mediterranean Sea, and the captured specimens are quickly frozen onboard fishing trawlers to preserve freshness and post-harvest quality. Here, we quantified the FAA profiles of DWRS packaged using five methods: (1) 100% N2; (2) vacuum; (3) 50% N2 + 50% CO2; (4) commercial anhydrous sodium sulfite; and (5) air (control). All samples were quickly frozen at −35°C and stored for 12 months at −18°C. Arginine (661 mg/100 g), proline …

Altri cibi. Il packaging degli alimenti veg
2017
Il tema di questo contributo riguarda il packaging dei prodotti vegani e vegetariani nel mercato italiano della distribuzione organizzata. La scelta degli ambiti del packaging della gdo e del vegetarianismo ha a che fare con le attuali tendenze dietetiche che, come spesso accade con le scelte e le mode alimentari, mentre si diffondono massivamente si intrecciano tra di loro. Se, infatti, in linea di principio l’astensione dal mangiare carne è il passaggio giusto e inevitabile per portare avanti coerentemente gli interessi degli esseri animali, ed è dunque espressione di una presa di posizione etico-politica animalista, è vero che cibi vegani e vegetariani sempre più spesso entrano a far par…
