Impact of a Pitanga Leaf Extract to Prevent Lipid Oxidation Processes during Shelf Life of Packaged Pork Burgers: An Untargeted Metabolomic Approach
2020
In this work, the comprehensive metabolomic changes in pork burgers treated with different antioxidants, namely, (a) a control without antioxidants, (b) 200 mg/kg butylated hydroxytoluene (BHT), and (c) 250 mg/kg pitanga leaf extract (PLE, from Eugenia uniflora L.), each one packaged under modified atmosphere (80% O2 and 20% CO2) for 18 days storage at 2 ±
Application of bacteriocins in vegetable food biopreservation.
2007
Bacteriocins are generally recognized as "natural" compounds able to influence the safety and quality of foods. In the past years, a lot of works have been aimed to the detection, purification and characterisation of bacteriocins, as well as to their use in food preservation strategies. A list of review articles dealing with the application of bacteriocins to the protection of foods of animal origin is also available in literature, but it lacks for a summary on the utilization of bacteriocins in vegetable foods. These biopreservatives can be used in a number of ways in food systems and this paper mainly focuses on the state-of-the-art application of bacteriocins from lactic acid bacteria (L…
The influence of Opuntia ficus-indica mucilage edible coating on the quality of ‘Hayward’ kiwifruit slices
2016
Abstract The aim of this work was to study the effect of mucilage edible coating extracted from Opuntia ficus-indica (OFI) on the quality and shelf life maintenance of packaged kiwifruit slices. OFI mucilage alone or added with TWEEN ® 20 were applied on kiwifruit fresh cut surfaces. After treatments, kiwifruit samples were stored under passive atmosphere at 5 ± 1 °C for 3, 5, 7 and 12 days. At each storage period, visual quality and flavor score, pectin content, ascorbic acid and the microbiological characteristics were measured together with CO 2 and O 2 content in the packages. Kiwifruit slices coated only with mucilage or with mucilage plus Tween 20, showed a significant higher firmness…
Efecto de la formalización y la confianza organizativa sobre la capacidad de ambidestreza. Estudio empírico en la industria agroalimentaria ecológica…
2018
Durante las últimas décadas, la ambidestreza ha despertado gran interés entre las organizaciones y los académicos. Para obtener una perspectiva completa del concepto de ambidestreza, investigaciones recientes han sugerido el estudio en profundidad de sus antecedentes. Estudios previos enfatizan que la ambidestreza necesita mecanismos de integración y factores contextuales para aumentar los flujos de conocimiento a través de las unidades organizativas de explotación y exploración (Gibson & Birkinshaw, 2004; Jansen, Tempelaar, Van den Bosch & Volberda, 2009). Sobre la base de una extensa revisión de la literatura, creemos que la formalización y la confianza se destacan como variables claves p…
Protecting from Oxygen (and from other gases)
2016
As mentioned in previous chapters, the benefits provided by innovation in the paper and board business are connected with the possible chemical modification of fibres, with coupling with other materials (composites), as well as with special surface treatments. Today paper and board can substitute polymers by virtue of their enhanced ability to act as barriers to gases, while displaying an active, antimicrobial, photocatalytic, etc. behaviour. The desired barrier effect is primarily against oxygen. Considerable interest was aroused in the past by substances like artificial or natural antioxidant additives, capable to act as a barrier to oxygen by preventing its action, as well as by solution…
The influence of backslopping on lactic acid bacteria diversity in tarhana fermentation
2020
Tarhana is produced at batch systems in which the microbiota has changed accordingly to the microbial load from ingredients. In order to stabilize the microbiota, the effects of backslopping carried out under different temperature regimes (25 and 30 °C), pH (3.70 and 4.00) and inoculation rates (5, 10 and 15%) on lactic acid bacteria (LAB) diversity were determined in tarhana dough. LAB and Total Aerobic Mesophilic Bacteria (TAMB) numbers increased in all tarhana dough samples subjected to backslopping. Temperature and pH significantly affected the microbiological diversity of tarhana whereas the different inoculation rates did not. Tarhana dough showed complex tarhana microbiota following …
Efectos de la gestión de la Calidad en el desarrollo de la exploración organizativa. Análisis de la industria agroalimentaria ecológica española
2021
La exploración organizativa se ha posicionado como un tema de gran interés, poco estudiado y de gran relevancia en la literatura actual, debido a su importancia como herramienta fundamental para asegurar la sostenibilidad, rentabilidad y supervivencia de las organizaciones (Greco, Charlier & Brown, 2019; Josephson, Johnson & Mariadoss, 2016; Levinthal & March, 1993). En cuanto a su relación con la gestión de la calidad y la formalización, en la literatura especializada no hay acuerdo sobre cuál es el papel que estas desempeñan en su desarrollo, con diferentes posturas a favor y en contra de estas relaciones. Basándonos en una extensa y profunda revisión de la literatura, nosotros analizamos…
Rapid Assessment of Gray Mold (Botrytis cinerea) Infection in Grapes with a Biosensor System
2015
Abstract: Botrytis cinerea is the causative agent of gray mold disease, which causes considerable economic losses to winemakers. The extent of gray mold infection of winegrapes is commonly visually estimated, a method that is prone to assessor bias. Here, we used rapid and simple enzyme-based screening consisting of carbon-electrode, screen-printed amperometric biosensors to estimate gluconic acid and glycerol concentration in winegrapes infected with different degrees of B. cinerea. The lower limits of quantification of the screen-printed amperometric biosensors were 3 mg/L for gluconic acid (corresponding to an infection rate of less than 1%) and 35 mg/L for glycerol; the response times w…
