Recent advances on intelligent packaging as tools to reduce food waste
2018
[EN] Food waste is one of the main issues for international organisms. It is not only an ethical and economic issue but it also depletes the environment of limited natural resources. Among strategies suitable for fighting such challenge, intelligent packaging is an interesting tool to reduce waste derived from households and retailers. A revision of 45 recent advances in the area of optical systems for freshness monitoring is reported herein. The study covers fruits, vegetables, fish products and meat since they are the most representative fields of application. Furthermore, a discussion about the main research challenges and opportunities that will be faced by intelligent packaging in the …

Sorption Equilibria of Ethanol on Cork
2013
International audience; We report here for the first time a thermodynamic study of gaseous ethanol sorption on raw cork powder and plate. Our study aims at a better understanding of the reactivity of this material when used as a stopper under enological conditions, thus in close contact with a hydroethanolic solution, wine. Sorption−desorption isotherms were accurately measured by thermogravimetry at 298 K in a large range of relative pressures. Sorption enthalpies were determined by calorimetry as a function of loading. Sorption−desorption isotherms exhibit a hysteresis loop probably due to the swelling of the material and the absorption of ethanol. Surprisingly, the sorption enthalpy of e…
Food Tray Sealing Fault Detection in Multi-Spectral Images Using Data Fusion and Deep Learning Techniques
2021
A correct food tray sealing is required to preserve food properties and safety for consumers. Traditional food packaging inspections are made by human operators to detect seal defects. Recent advances in the field of food inspection have been related to the use of hyperspectral imaging technology and automated vision-based inspection systems. A deep learning-based approach for food tray sealing fault detection using hyperspectral images is described. Several pixel-based image fusion methods are proposed to obtain 2D images from the 3D hyperspectral image datacube, which feeds the deep learning (DL) algorithms. Instead of considering all spectral bands in region of interest around a contamin…
High throughput electro-hydrodynamic processing in food encapsulation and food packaging applications: Viewpoint
2017
Abstract Looking genuinely at nature, nanofibers often serve as a basic platform where either organic or inorganic components are built upon. The fiber structure exhibits, from a structural point of view, the intrinsic ability to mechanically reinforce materials but also the less well-known property of enhancing the barrier performance of polymer matrices when applied smartly. To reproduce and tailor this extraordinary nature's design, a reliable technology that is able to fabricate fiber nanostructures from a variety of materials with size and size distribution control and composition flexibility is highly desirable. In addition, if this technology could allow nanofiber shortening to achie…
Liquid chromatography‐Orbitrap Tribrid high‐resolution mass spectrometry using data dependent‐tandem mass spectrometry with triple stage fragmentatio…
2021
A new, fast, and automatic approach has been applied for the tentative identification of unknown substances released by food contact epoxy resin after performing a migration test with food simulant. This approach combines intelligent data acquisition with AcquireX linked to liquid chromatography-Orbitrap Tribrid high-resolution mass spectrometry using data dependent-tandem mass spectrometry with triple stage fragmentation coupled to Compound Discoverer™ software for automated data processing and compound identification. The identification of the observed features was performed using a set of identification criteria, including exact mass, isotope pattern, tandem mass spectrometry spectra mat…
Recent European Food Safety Authority toxicological evaluations of major phthalates used in food contact materials
2009
During the 1980s and 1990s, and at the EU level, the Scientific Committee for Food evaluated a number of phthalates that were being used, or were requested for use, as additives in plastics. At this time, peroxisome proliferation was considered as the pivotal effect on which toxicological evaluation of these chemicals was based. At the end of 1990s, a general consensus has been agreed that rodents are highly sensitive to the phenomenon of peroxisome proliferation and that this particular effect should not be used for human risk assessment. Consequently in 2004, it was requested from the newly created European Food Safety Authority to perform a new evaluation of the mainly used phthalates on…
An overview of nanoparticles role in the improvement of barrier properties of bioplastics for food packaging applications
2017
Abstract Plastics are the most demanding materials for the food packaging industry due to economical and practical reasons such as their low cost, lightness, easy to handle in integrated production lines, and their higher resistance than other materials. Besides containment and information, the packaging should protect foodstuffs from not only contamination but also the loss of food quality. Despite the many advantages, their inherent permeability is perhaps the foremost drawback that could lead to the loss of some food components and, also, to the transference of gases or moisture from the surrounding to the food. Thus, the barrier properties and the wettability are of fundamental importan…
Nanomaterials in Food, Which Way Forward?
2012
Abstract Nanotechnology has emerged as one of the most innovative technologies occurred in decades and has the potential to improve food quality and safety. At present, there are also a few studies demonstrating that nanomaterials (NMs) are not inherently benign. This chapter highlights some current applications of NMs in food, food additives and food contact materials and reviews analytical approaches suitable to address food safety-related issues of nanotechnology. As starting point, discussion on the current regulatory situation of nanotechnology in relation to food is addressed, followed by a detailed description of sample preparation aspects, separation methods (e.g. field-flow fractio…
Towards a more sustainable food Supply chain: opening up invisible waste in food service
2016
Future challenges to the global food supply chain are complex. In order to embrace sustainability, companies should change their management practices towards more efficient resource use. Food waste being a misuse of resources, we identify its causes and possible ways of minimising it. To achieve this goal, we conducted explorative research with qualitative and quantitative data through in-depth semi-structured interviews and an open questionnaire with top Spanish food service companies. Results show that most businesses mainly tend to minimise food waste according to economic criteria, without taking into account the social, ethical or environmental factors. As a consequence, just “visible”…
