Book Description
Food-scanners are novel, portable and miniaturized devices, which operate on the principle of near-infrared spectroscopy (NIRS). According to the manufacturers, these devices are suitable for measuring a wide range of important quality parameters on fresh produce. This research evaluated the suitability of food-scanners for determining fruit quality along the supply chain of fruit and vegetables. Using the qualitative research approach, the first step of this research comprised interviews of experts at different positions along the fresh produce value chain in Germany. Thereby, preferences and concerns regarding the utilization and implementation of this technology for fresh produce were investigated. Based on these findings, non-destructive prediction models for various important quality characteristics and secondary plant constituents were developed using the model fruit tomato. In addition, food-scanner predictions of relevant quality traits on a wide range of produce from the fruit and vegetable assortment were examined. The evaluations showed a high degree of conformity between the results of non-destructive food-scanner predictions and conventional destructive measurement methods. The results illustrate the great potential of these novel devices for the application in everyday practice of fruit quality control along the fresh produce supply chain.

Book Description
This thesis presents the major viruses affecting three cultivars in Colombia and how experimental approaches in serology, molecular biology, and bioinformatics can be adapted to create a protocol that could be applied for physalis, passionfruit, ornamental rose, and eventually other crops. Selection of farms was carried out based on size and economic importance. Initial visual plant symptom appraisal led collection of 370 samples from 20 farms. Literature review guided the selection of antibodies of known viruses for initial ELISA testing. Thereafter NGS was carried out to discover further known and novel viruses in the cultivars. Various experiments were carried out on different samples including biotest inoculation, ELISA, RT-PCR, and NGS. Reliable and practical diagnostic tools like these could be developed for the most important viruses leading to a national agricultural certification program that could be established in a common project between German and Colombian universities, the Colombian Agricultural Institute (ICA), the Colombian Corporation of Agricultural Investigation (AGROSAVIA), and the International Center for Tropical Agriculture (CIAT). In dieser Arbeit werden die wichtigsten Viren vorgestellt, die drei Sorten in Kolumbien betreffen, und wie experimentelle Ansätze in den Bereichen Serologie, Molekularbiologie und Bioinformatik angepasst werden können, um ein Protokoll zu erstellen, das für Physalis, Passionsfrucht, Zierrose und eventuell andere Kulturen angewendet werden kann. Die Auswahl der Betriebe erfolgte nach Größe und wirtschaftlicher Bedeutung. Die erste visuelle Beurteilung der Pflanzensymptome führte zur Entnahme von 370 Proben aus 20 Betrieben. Die Literaturrecherche leitete die Auswahl von Antikörpern bekannter Viren für erste ELISA-Tests. Danach wurde NGS durchgeführt, um weitere bekannte und neuartige Viren in den Sorten zu entdecken. Verschiedene Experimente wurden an verschiedenen Proben durchgeführt, einschließlich Biotest-Inokulation, ELISA, RT-PCR und NGS. Solche zuverlässigen und praktischen Diagnosewerkzeuge könnten für die wichtigsten Viren entwickelt werden, die zu einem nationalen Agrarzertifizierungsprogramm führen, das in einem gemeinsamen Projekt zwischen deutschen und kolumbianischen Universitäten, dem Colombian Agricultural Institute (ICA) und der Colombian Corporation of Agricultural Investigation (AGROSAVIA), und das Internationale Zentrum für tropische Landwirtschaft (CIAT) eingerichtet werden könnte.

Book Description
Hyperspectral imaging or imaging spectroscopy is a novel technology for acquiring and analysing an image of a real scene by computers and other devices in order to obtain quantitative information for quality evaluation and process control. Image processing and analysis is the core technique in computer vision. With the continuous development in hardware and software for image processing and analysis, the application of hyperspectral imaging has been extended to the safety and quality evaluation of meat and produce. Especially in recent years, hyperspectral imaging has attracted much research and development attention, as a result rapid scientific and technological advances have increasingly taken place in food and agriculture, especially on safety and quality inspection, classification and evaluation of a wide range of food products, illustrating the great advantages of using the technology for objective, rapid, non-destructive and automated safety inspection as well as quality control. Therefore, as the first reference book in the area, Hyperspectral Imaging Technology in Food and Agriculture focuses on these recent advances. The book is divided into three parts, which begins with an outline of the fundamentals of the technology, followed by full covering of the application in the most researched areas of meats, fruits, vegetables, grains and other foods, which mostly covers food safety and quality as well as remote sensing applicable for crop production. Hyperspectral Imaging Technology in Food and Agriculture is written by international peers who have both academic and professional credentials, with each chapter addressing in detail one aspect of the relevant technology, thus highlighting the truly international nature of the work. Therefore the book should provide the engineer and technologist working in research, development, and operations in the food and agricultural industry with critical, comprehensive and readily accessible information on the art and science of hyperspectral imaging technology. It should also serve as an essential reference source to undergraduate and postgraduate students and researchers in universities and research institutions.

Book Description
In the last few decades, near-infrared (NIR) spectroscopy has distinguished itself as one of the most rapidly advancing spectroscopic techniques. Mainly known as an analytical tool useful for sample characterization and content quantification, NIR spectroscopy is essential in various other fields, e.g. NIR imaging techniques in biophotonics, medical applications or used for characterization of food products. Its contribution in basic science and physical chemistry should be noted as well, e.g. in exploration of the nature of molecular vibrations or intermolecular interactions. One of the current development trends involves the miniaturization and simplification of instrumentation, creating prospects for the spread of NIR spectrometers at a consumer level in the form of smartphone attachments—a breakthrough not yet accomplished by any other analytical technique. A growing diversity in the related methods and applications has led to a dispersion of these contributions among disparate scientific communities. The aim of this Special Issue was to bring together the communities that may perceive NIR spectroscopy from different perspectives. It resulted in 30 contributions presenting the latest advances in the methodologies essential in near-infrared spectroscopy in a variety of applications.
