Stabilization of a nutraceutical omega-3 fatty acid by encapsulation in ultrathin electrosprayed zein prolamine.
2010
Docosahexaenoic acid (DHA) is a long chain polyunsaturated fatty acid of the omega-3 series (omega-3), which exerts strong positive influences on human health. The target of this study was the stabilization by encapsulation of this bioactive ingredient in zein ultrathin capsules produced by electrospraying. The zein ultrathin DHA encapsulation was observed by ATR-FTIR spectroscopy to be more efficient against degradation under both ambient conditions and in a confined space (so-called headspace experiment). In the latter case, that more closely simulates a sealed food packaging situation, the bioactive DHA was considerably more stable. By fitting the degradation data to a specific auto-deco…
The Complex Regulatory Role of Cytomegalovirus Nuclear Egress Protein pUL50 in the Production of Infectious Virus
2021
The regulation of the nucleocytoplasmic release of herpesviral capsids is defined by the process of nuclear egress. Due to their large size, nuclear capsids are unable to traverse via nuclear pores, so that herpesviruses evolved to develop a vesicular transport pathway mediating their transition through both leaflets of the nuclear membrane. This process involves regulatory proteins, which support the local distortion of the nuclear envelope. For human cytomegalovirus (HCMV), the nuclear egress complex (NEC) is determined by the pUL50-pUL53 core that initiates multicomponent assembly with NEC-associated proteins and capsids. Hereby, pUL50 serves as a multi-interacting determinant that recru…
Fresh-cut products from cactus species
2005
Various species of Cactaceae family can serve a source of delicious and healthy fresh foodstuffs. Marketing cacti as ready-to-eat (fresh-cut) products may significantly expand their consumption, on condition that their quality, safety and longevity would answer the market demands. The present work was aimed at studying the storability of fresh-cut products prepared from several edible cactus species and looking for ways to improve their keeping quality. The experiments included fruit of cactus pear Opuntia ficus-indica (L.) Miller, cactus apple (koubo) Cereus peruvianus (L.) Miller, and dragon fruit (pitaya) Hylocereus undatus (Haw.) Britton and Rose, as well as cladodes (pads) of nopal (ve…
Novel Multifunctional Polymeric Photoinitiators and Photo-Coinitiators Derived from Hyperbranched Polyglycerol
2007
A new class of hyperbranched PPIs and PPCs have been prepared. The introduction of compatibilizing groups such as MEEA or trimethylacetate enhanced their solubility in radiation-curable formulations and led to an improved photoactivity compared with the corresponding MPI and MPC. Although the molecular weights of the subject PPIs and PPCs exceeded 800 g mol -1 , the viscosities of the radiation-curable formulations were still suitable for inkjet application. The combination of high photoactivity, low viscosity, and low extract-ability after curing rendered the resulting hyperbranched PPIs and PPCs attractive as components in the inkjet ink for inkjet printing, e.g., in food packaging.
The Unintended Side Effects of Bioplastics: Carbon, Land, and Water Footprints
2020
(One Earth 3, 45–53, July 24, 2020) In the originally published version of this article, the authors inadvertently used global volumes of bioplastics in plastic packaging instead of European volumes for Figure 1C. After noticing this, the authors recalculated European bioplastic packaging consumption, and as such, Figure 1 and its legend have been corrected in the online article (as shown below) to reflect all data sources used for estimating European bioplastic volumes in Figure 1C. In the Experimental Procedures, the Data and Code Availability section has been updated, and the section “Estimation of European Bioplastic Volumes” has been added. Additionally, reference 69 is new, and two in…
Life cycle energy and CO2 emissions analysis of food packaging: an insight into the methodology from an Italian perspective
2016
Packaging is strictly connected to environmental issues as it is a product characterised by high material consumption rate; it is often transported over long distances and has a short life. Providing environmental analysis is, therefore, urgent to identify energy and resources efficient solutions. The paper, taking advantage of a real case study, presents a life cycle-based comparative analysis among three different food packaging systems. The paper compares the life cycle of tin steel, polypropylene and glass-based packaging of an Italian preserves producer. The analysis leads to the conclusion that, for the baseline scenario, polypropylene packaging represents the greenest solution, where…
Commercial versus technical cues to position a new product: Do hedonic and functional/healthy packages differ?
2017
Packaging attributes can be classified into two main blocks: visual/commercial attributes and informational/technical ones. In this framework, our objectives are: (i) to compare if both kinds of attributes lead to equal responses (consumers' attitudes improvement and product trial) and (ii) to compare if they work equally when a hedonic or a healthy new product is launched into the young market. An experimental design was defined to reach both objectives. Two packaging attributes were manipulated orthogonally to introduce greater variation in people's perceptions: a visual cue (the color) and an informative cue (the claim/label). A third variable was introduced: hedonic (candy bars) versus …
Designing a packaging to promote healthy and low-fat foods: Adolescents versus young-adults
2017
Packaging is a relevant tool when adolescents and young adults search for low-fat and healthy foods. However, the power of a packaging is not homogenous. In this framework, two main objectives guide our work: (i) to investigate to what extent visual cues (size, colors, images etc.) are more important than informational cues (label); (ii) to analyze if adolescents and young adults pay equal attention to both packaging cues. 590 adolescents between 12 and 18years of age were interviewed at the door of both public and private schools. Additionally, 300 young adults between 19 and 25years of age were contacted. Their opinions were analyzed twice using structural modelling techniques: (i) withou…
Prenatal exposure to phthalates and its effects upon cognitive and motor functions : a systematic review
2021
Este artículo se encuentra disponible en la página web de la revista en la siguiente URL: https://www.sciencedirect.com/science/article/pii/S0300483X21003024?via%3Dihub Phthalates are chemicals widely used in packaging and consumer products, which have been shown to interfere with normal hormonal function and development in some human and animal studies. In recent decades, pregnant women’s exposure to phthalates has been shown to alter the cognitive outcomes of their babies, and some studies have found delays in motor development. Methods: electronic databases including PubMed/MEDLINE and Scopus were searched from their inception to March 2021, using the keywords "phthalate", "cognitive" an…
Consumers' physiological and verbal responses towards product packages: Could these responses anticipate product choices?
2019
Today, it is a priority to predict what consumers will choose at the point of sale where there are more and more competing brands. But what kind of consumers' information can be used for that purpose? This paper compares the power of physiological responses (unconscious responses) and self-report/verbal responses (conscious responses) towards product packages, as a means of predicting product choices. To this end, six different packaging designs were created by combining three different colors (blue, red and black) and two different messages (simple and reinforced). Eighty-three young consumers were exposed to each of the six designs. In one phase of our investigation, unconscious electrode…
