Half a Century of Research on Membrane-Containing Bacteriophages: Bringing New Concepts to Modern Virology
2019
Half a century of research on membrane-containing phages has had a major impact on virology, providing new insights into virus diversity, evolution and ecological importance. The recent revolutionary technical advances in imaging, sequencing and lipid analysis have significantly boosted the depth and volume of knowledge on these viruses. This has resulted in new concepts of virus assembly, understanding of virion stability and dynamics, and the description of novel processes for viral genome packaging and membrane-driven genome delivery to the host. The detailed analyses of such processes have given novel insights into DNA transport across the protein-rich lipid bilayer and the transformati…
Designing food packaging for the Spanish market: Do motivations differ between involved and non-involved adolescents?
2018
Abstract This paper investigates the relationships among food choice motivations and the relevance of packaging elements (visual and informative elements) in the adolescent market. In addition, these relationships are re-tested in two different frameworks: high-involved consumers and low-involved consumers. 590 young consumers between 13 and 17 years were interviewed at the door of their public or private schools. Structural Modelling was used to test our hypotheses. The first analysis was done considering the global sample. The second one split off the sample into two groups: 351 high-involved adolescents and 239 low-involved adolescents. Our results showed, on one side, that weight contro…
Impact of packaging on the microbiological, physicochemical and sensory characteristics of a “pasta filata” cheese
2018
Abstract The present study evaluated the effects of four packaging technologies (vacuum, 2 types of modified atmosphere packaging [MAP1 = 70% N2/30% CO2; MAP2 = 100% N2] and paraffin) on the microbiological, chemical, physical and volatile organic composition, and the sensory characteristics of typical Sicilian stretched raw milk PDO (Protected Destination of Origin) Vastedda della Valle del Belice (VdB) cheese. The packaging applied did not affect the microbiological profiles of the cheeses. Of the chemical and physical parameters, only pH and water activity (aw) were statistically different among the trials. In particular, the cheeses wrapped in paraffin showed the highest pH value while …
Toward shrimp consumption without chemicals: Combined effects of freezing and modified atmosphere packaging (MAP) on some quality characteristics of …
2015
The combined effects of freezing and modified atmosphere packaging (MAP) (100% N2 and 50% N2 + 50% CO2) on some quality characteristics of Giant Red Shrimp (GRS) (Aristaeomorpha foliacea) was studied during 12-month storage. In particular, the quality characteristics determined proximal and gas compositions, melanosis scores, pH, total volatile basic-nitrogen (TVB-N), thiobarbituric acid (TBA) as well as free amino acid (FAA). In addition, the emergent data were compared to those subject to vacuum packaging as well as conventional preservative method of sulphite treatment (SUL). Most determined qualities exhibited quantitative differences with storage. By comparisons, while pH and TVB-N sta…
Effects of innovative and conventional sanitizing treatments on the reduction of Saccharomycopsis fibuligera defects on industrial durum wheat bread
2016
Wickerhamomyces anomalus, Hyphopichia burtonii and Saccharomycopsis fibuligera are spoilage yeasts causing chalk mold defects on sliced bread packaged under modified atmosphere. The first objective of this study, carried out in a bread-making company for two consecutive years, was to genetically identify yeasts isolated from spoiled sliced bread in Modified Atmosphere Packaging (MAP) and to determine the dominant species among identified strains. The second objective was to evaluate the effects of hydrogen peroxide and silver solution 12% (HPS) treatment in the leavening cells and cooling chambers, in comparison with the conventional Ortho-Phenylphenol (OPP) fumigating treatment, on the inc…
Edible films/coating with tailored properties for active packaging of meat, fish and derived products
2020
Abstract Background Meat, fish and derived products are perishable food items with quick deterioration under improper storage. Edible films and/or coatings present an interesting approach to preserve and package these foods. These are composed of biopolymers generated from food industry wastes or underutilized sources of proteins, lipids, or polysaccharides that are biodegradable, edible and can act as carriers with active agents from natural sources. Scope and approach The protective effect of active films and coatings in meat, fish and derived products against quality decay during storage is described. This review reinforces the benefits of active films and coatings incorporated with natu…
Risk assessment of exposure to phthalates in breastfeeding women using human biomonitoring
2020
In this study, we assessed the presence of 14 phthalate metabolites in the urine of 104 lactating mothers from Valencia (Spain) who took part in the human biomonitoring project BETTERMILK. Nine of the metabolites studied showed detection frequencies >80%, whereas the rest of the metabolites presented low detection frequencies (<5%). The concentrations ranged from <LoQ to 1291 ng/mL with monoethyl phthalate showing the highest concentration, with a geometric mean of 34.90 ng/mL. In general, the phthalate metabolite levels quantified in the present study were lower than the urinary levels found in previous studies that involved lactating mothers. The consumption of packaged juices and the fre…
Food packaging cues as vehicles of healthy information: Visions of millennials (early adults and adolescents)
2018
Abstract Because packaging has become an important marketing tool, firms must know what type of packaging can affect consumers' packaging cues. Also, still today there is little attention paid to the relevance of educating millennials about the importance of a healthier lifestyle and eating. The aim is to analyse the effects of young consumers with varying degrees of healthy lifestyles and food involvement on packaging cues. Also, the paper analyses differences between early adults and adolescents millennials. Using a sample of 890 millennials (300 early adults and 590 adolescents) and SEM methodology, interesting results are reached. Some healthy habits affect food involvement, and this is…
Impact of bioactive packaging systems based on EVOH films and essential oils in the control of aflatoxigenic fungi and aflatoxin production in maize.
2017
Aspergillus flavus and A. parasiticus are the most common fungal species associated with aflatoxin (AF) contamination of cereals, especially maize, and other agricultural commodities. AFB1, the most frequent and toxic metabolite, is a powerful hepatotoxic, teratogenic and mutagenic compound. Effective strategies to control these fungal species and AFs in food and feed are required. Active packaging film containing essential oils (EO) is one of the most innovative food packaging concepts. In this study, ethylene-vinyl alcohol (EVOH) copolymer films incorporating EO from Origanum vulgare (ORE), Cinnamomum zeylanicum (CIN) or their major active constituents, carvacrol (CAR) and cinnamaldehyde …
Influence of the antimicrobial compound allyl isothiocyanate against the Aspergillus parasiticus growth and its aflatoxins production in pizza crust.
2015
Abstract Aflatoxins (AFs) are secondary metabolites produced by different species of Aspergillus, such as Aspergillus flavus and Aspergillus parasiticus, which possess mutagenic, teratogenic and carcinogenic activities in humans. In this study, active packaging devices containing allyl isothiocyanate (AITC) or oriental mustard flour (OMF) + water were tested to inhibit the growth of A. parasiticus and AFs production in fresh pizza crust after 30 d. The antimicrobial and anti-aflatoxin activities were compared to a control group (no antimicrobial treatment) and to a group added with commercial preservatives (sorbic acid + sodium propionate). A. parasiticus growth was only inhibited after 30 d…
