Characteristics of Wild Pear ( Pyrus glabra Boiss) Seed Oil and Its Oil‐in‐Water Emulsions: A Novel Source of Edible Oil
2017
The observed high consumer demand for edible oils with high oxidative stability resulted in notable efforts to investigate wild plants as new sources of oils and fats. In this context, the fatty acid profile, total tocopherols, tocotrienols and phenolic compounds, as well as oxidative stability parameters such as peroxide value (PV), conjugated dienes (CD), conjugated trienes (CT), anisidine value (AnV), and kinetic parameters of wild pear (Pyrus glabra Boiss.) seed oil as a novel source of edible oil were investigated. In addition, the oil-in-water emulsion was prepared from wild pear seed oil. Considering the fatty acid profile, linoleic (56.8±1.4g/100 g oil) and oleic acid (27.4±0.6 g/10…
Review: the Use of Electromyography on Food Texture Assessment
2001
Sensory evaluation (SE) involves evoking, measuring and interpreting human responses to the properties of foods. Among these properties texture is an important one for food acceptability. Texture is mainly perceived through mastication, a process that changes food characteristics throughout time by comminuting and salivation. Electromyography (EMG) has emerged as a new tool in sensory evaluation mainly for assessing texture characteristics. Thus, it is interesting to analyze the knowledge so far generated and the procedures employed. Bipolar surface electrodes are placed on the four main masticatory muscles (masseter right-left and temporalis right-left) and their electric activity recorded…
The Burden of Respiratory Syncytial Virus Disease in Pre-Term Infants
2015
This mini-review summarises the risk factors for acquiring Respiratory Syncitial Virus (RSV) infection, and describes the harmful effects of the infection in pre-term infants. Moreover, theoretical considerations are discussed for the prevention of RSV infection in high-risk infant categories, such as pre-term infants. Background: Neonates positive for RSV are more prone to severe infection than neonates infected with other common respiratory viruses. Despite RSV infection being more common in late neonates than in early ones, pre-term infants ≤ 35 wk gestational age (GA) are at high risk for developing severe RSV disease. Efforts to prevent infection include case management, vaccination an…
Stability of vacuolar betaxanthin pigments in juices from Moroccan yellow Opuntia ficus indica fruits
2008
Pigment stability of yellow juices prepared from Moroccan cactus pear (Opuntia ficus indica) was determined as a function of temperature and pH. The experiments were carried out at temperatures ranging from 80 to 100 °C with juices at pH 3.5, 5 and 6.5. The degree of pigment retention decreased when the temperature increased. The degradation constant rates were determined for thermal degradation rates of pseudo-first order. The Arrhenius plot obtained for the degradation of betaxanthin from the yellow fruits was not linear. Regardless of the temperature treatment, the lowest degradation was obtained for pH 5. Where some stabilizers were tested for the protection of pigments, the results sho…
Quality and volatile compounds in red wine at different degrees of dealcoholization by membrane process
2019
This study investigated the effect of different degrees of dealcoholization on volatile compounds, phenols and sensory characteristics of red wine (cv. Montepulciano d’Abruzzo). The wine with an initial alcohol content of 13.2% v/v was partially dealcoholized by membrane process with a decrease of alcohol degree as follows: − 4.9; − 6.3; − 7.8, − 9.2 and − 10.5% v/v. Osmotic distillation has proved effective in preserving a satisfactory odorous profile, as samples with an alcohol residue of 8.3% v/v (− 4.9%) and 6.9% v/v (− 6.3%) showed good esters retention: more than 84% and 82%, respectively. Similarly, colour and taste, evaluated by flavonoids and phenolic compounds, remained almost unc…
Role of biological control agents and physical treatments in maintaining the quality of fresh and minimally-processed fruit and vegetables
2019
International audience; Fruit and vegetables are an important part of human diets and provide multiple health benefits. However, due to the short shelf-life of fresh and minimally-processed fruit and vegetables, significant losses occur throughout the food distribution chain. Shelf-life extension requires preserving both the quality and safety of food products. The quality of fruit and vegetables, either fresh or fresh-cut, depends on many factors and can be determined by analytical or sensory evaluation methods. Among the various technologies used to maintain the quality and increase shelf-life of fresh and minimally-processed fruit and vegetables, biological control is a promising approac…
Groupthink and Project Performance: The Influence of Personal Traits and Interpersonal Ties
2015
Contains fulltext : 166103.pdf (Publisher’s version ) (Closed access) This study explores whether the negative impact of “groupthink concurrence-seeking behavior” (GTB) on business process reengineering (BPR) projects is affected by group members personal traits and interpersonal ties within the group. To this purpose we conduct and present the results of a longitudinal controlled field experiment over 18 BPR projects lasting 3 months and involving 18 teams comprising 71 first-year MBA students. The main contribution of this study is twofold. First, we explicitly consider and measure the core construct of groupthink phenomenon: that is, GTB. Existing organizational behavior literature has, …
Learners’ attitudes to first, second and third languages pronunciation in structuring multilingual identity
2022
Abstract This paper investigates multilingual learners’ attitudes to native (L1 – Ukrainian), second (L2 – Polish) and foreign (L3 – English) languages’ pronunciation, and discusses them from the perspective of structuring multilingual identity. In the study, the choice of the sample has been controlled in terms of the participants’ nationality and the context in which they acquire their second and foreign languages – variables that are interwoven in shaping identities. More specifically, the 40 Ukrainian individuals, taking part in the study, are in the process of a foreign language acquisition, English, embedded in the context of their second language, Polish. The attitudes to L1, L2 and …
The Case for Contingent Convertible Debt for Sovereigns
2015
We make the case for sovereigns to issue contingent convertible bonds as a means to forestall debt crises. These instruments contractually stipulate payment standstill, contingent on a sovereign’s credit default swap spread breaching a distress threshold. This is a financial innovation solution to the lack of sovereign debt restructuring mechanisms, limiting ex ante the likelihood of debt crises and imposing ex post risk sharing between creditors and the debtor. The new instruments are contingent contracts addressing neglected risks in sovereign debt. Building on literature for contingent convertible debt for banks we address the design of sovereign contingent debt, including market discipl…
Automated Valuation Methods in Atypical Real Estate Markets Using the Mono-parametric Approach
2017
The appraisal objectivity depends on the possibility to quickly and easily access to reliable real estate data in order to apply appropriate appraisal approaches. In order to ensure the objectivity of the real estate appraisals, in recent years Automated Valuation Methods (AVM) have been developed, integrating computerized real estate databases and programming languages. The Automated Valuation Methods proposed at international level usually recur to regression models, aimed to return appraisal equations based on reliable real estate databases. This approach is not applicable in some markets where lack of data does not allow the implementation of regression models. This paper proposes to im…
