This chapter provides an overview of the gender aspects that are relevant to Talent Management, acknowledging gender as a social construction of the purportedly adequate behaviors and traits exhibited by males and females as the result of education and socialization processes. It discusses gendered perspectives and the needs of current and future key players, such as work–family balance and dual-career challenges, because they influence the decisions of talent to join, remain with, or leave organizations. The chapter focuses on well-qualified female professionals who are willing to invest in themselves and value their significant involvement in their work. By applying a gender lens, it addresses a gap in the Talent Management discussion and aims to contribute to the development of Talent Management on both the theoretical and practical level. If Talent Mangement systematically includes employees in mid- and late career and enables them to learn throughout their careers, it will expand its target groups.
The effect of pulsed electric field (PEF) and ultrasound (US) on the frying behavior of potato chips was investigated. For this purpose, a special fryer with a window was designed to enable the investigation of water evaporation by the characterization of bubble formation during frying. The number of water vapor bubbles and the bubble volume distribution were analyzed in order to gain an insight into heat and mass transfer affected by PEF and US treatment. Quality parameters of the potato chips such as moisture, fat and acrylamide content were measured. Overall, the results of this study show for the first time impacting effects on the frying process that can be achieved by combining PEF as a volumetric cell disintegration technology and ultrasound as a mean to affect interface phenomena. The obtained results can be used to further optimize frying processes used for the production of chips and other products.
While the Food and Biotechnology industries often use unit operations that have been known for some time, sometimes these processes are not efficient or sustainable. The need to develop more efficient processing lines to obtain higher quality products is of utmost importance. Over the last years, pulsed electric fields (PEF) processing has attracted the interest of numerous researchers and companies due to its ability to reduce processing time, preserve thermolabile compounds, which are responsible for the aroma, nutritional and bioactive properties of food products.
Therefore, in this article, some of the most important studies regarding the application of PEF technology in food and biotechnology processing is discussed.
Chlorophyllfluoreszenz als Werkzeug für die DCA-Lagerung von Äpfeln (Malus x domestica BORKH.)
(2024)
Äpfel besitzen mehrere Allergene, die beim Essen innerhalb von 5–10 min zu Symptomen im Mundbereich führen – und deshalb von Apfelallergikern nicht gegessen werden können. In Deutschland haben rund 7,5 Mio. Menschen spezifische Antikörper gegen das Hauptallergen (Mal d 1) in Äpfeln entwickelt und sind damit sensibilisiert. Mindestens 3,5 Mio. von ihnen entwickeln die teilweise erheblichen allergischen Symptome als Ausdruck eines Oralen Allergie-Syndroms. Es gibt bisher keine medikamentöse Therapie gegen diese Allergie.
Apfelallergiker können daher nur auf Äpfel ganz verzichten, oder vorher erhitzte Äpfel essen oder Sorten suchen, die wenig Allergene enthalten und deshalb als allergikerfreundliche Apfelsorten bezeichnet werden können.
Alleinige Bestimmungen von Allergenen im Labor können nicht voraussagen, ob ein Apfel ohne allergische Symptome von Apfelallergikern gegessen werden kann; dazu bedarf es klinischer Prüfungen.
Wir beschreiben eine standardisierte klinische, orale Provokationstestung, die zur Charakterisierung eines allergenarmen, allergikerfreundlichen Apfels bzw. Apfelsorte benutzt werden kann.. Die Ergebnisse solcher mindestens dreijährigen Tests können zur Verleihung des ECARF-Siegels für allergikerfreundliche Produkte genutzt werden.
Currently, only non-imaging chlorophyll fluorescence measurements are used to identify the Lower Oxygen Limit (LOL) in Dynamic Controlled Atmosphere - Chlorophyll Fluorescence (DCA-CF) storage. The disadvantage of non-imaging fluorescence is that no statement can be made about the spatial heterogeneity of the sample. In contrast, chlorophyll fluorescence imaging can detect spatial heterogeneity of photosynthetic activity and has been established in research for some decades because the information benefit is higher. In this study, the chlorophyll fluorescence (Fo, Fm, Fv, Fv/Fm) of apples (Malus x domestica, BORKH.) was measured with a fluorescence imaging system in situ during storage. Intact apples of ‘Braeburn’ and ‘Golden Delicious’ were stored under low-oxygen stress conditions (< 1 kPa). The metabolic shift from aerobic to fermentative metabolism was made visible with the chlorophyll fluorescence imaging and was spatially localized on the sample. Furthermore, a method was developed to identify the LOL based on the chlorophyll fluorescence imaging combined with the histogram division method. This method considers the heterogeneity of the fluorescence and bundles the measured Fo data as histograms. Our results showed that the fluorescence imaging combined with the histogram division method can be a powerful tool for identifying the LOL.
