Microbial loads, rapid tissue browning, and loss of texture and flavour limit their customers' acceptability. Therefore, postharvest storage in sugar-syrup or suitable fruit juice solutions are common practices to extend shelf life. However, knowledge on the effects of these applications on the produce are sketchy. Nevertheless, adequate and gentle sanitation is essential, and short-term hot-water treatment (sHWT) may be an effective method to reduce microbial contaminations. For fruit salad production, however, sHWT needs to be optimised. Objective of this thesis was the evaluation of the effects of complete immersion of fresh-cut apple slices in sugar solution or orange juice on quality attributes and physiology. This thesis analysed the potential synergistic interactive effects caused by sugar syrup immersion of apple slices and reduced O2 availability on the emissions of volatile organic compounds. In addition, the potential implications of sHWT in the temperature range of 55-65 °C on quality attributes, fruit aroma and product physiology of immersed fresh-cut apple slices were investigated.

Frisch geschnittene Äpfel haben eine kurze Haltbarkeit. Mikrobielles Wachstum, schnelle Gewebebräunung und der Verlust von Textur und Geschmack schränken die Akzeptanz des Kunden ein. Daher ist die Lagerung nach der Ernte in Zuckersirup oder geeigneten Fruchtsaftlösungen eine gängige Praxis, um die Haltbarkeit zu verlängern. Die Kenntnisse über die Auswirkungen dieser Anwendungen auf die Erzeugnisse sind jedoch lückenhaft. Zudem kann eine Kurzzeit-Heißwasserbehandlung (sHWT) eine wirksame Methode zur Verringerung mikrobieller Kontaminationen sein. Für die Obstsalatherstellung muss die sHWT jedoch optimiert werden. Ziel dieser Arbeit war die Bewertung des vollständigen Eintauchens von frisch geschnittenen Apfelscheiben in Zuckerlösung oder Orangensaft in Bezug auf Produktqualität und -physiologie. Es wurden die potenziellen synergistischen Wechselwirkungen zwischen dem Eintauchen der Apfelscheiben in Zuckersirup und der reduzierten Sauerstoffverfügbarkeit auf die Emission flüchtiger organischer Verbindungen untersucht. Darüber hinaus wurden die potenziellen Auswirkungen einer sHWT im Temperaturbereich von 55-65 °C auf die Qualitätsmerkmale, das Fruchtaroma und die Produktphysiologie von eingetauchten, frisch geschnittenen Apfelscheiben untersucht.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This Brief reviews the effects of increasing and reducing atmospheric pressure on the postharvest life of fruit and vegetables. The text covers the common methods and technologies used and evaluates the history and benefits of hypobaric and hyperbaric storage. Both of these techniques have the potential to address quantitative and qualitative challenges in the postharvest sector of the fresh fruit and vegetables industry. Hypobaric and Hyperbaric Storage of Fruit and Vegetables reports on the effects of storage on over 45 types of fruit and vegetables, as well as on whole plants and cut flowers. As consumer demand for high quality product increases, proper postharvest storage will continue to gain in importance. The environmental conditions used in storage have a vital influence on the quality, safety and health benefits of fruit and vegetables.

Available in PDF, EPUB and Kindle. Book excerpt: The processing of fruits continues to undergo rapid change. In the Handbook of Fruits and Fruit Processing, Dr. Y.H. Hui and his editorial team have assembled over forty respected academicians and industry professionals to create an indispensable resource on the scientific principles and technological methods for processing fruits of all types. The book describes the processing of fruits from four perspectives: a scientific basis, manufacturing and engineering principles, production techniques, and processing of individual fruits. A scientific knowledge of the horticulture, biology, chemistry, and nutrition of fruits forms the foundation. A presentation of technological and engineering principles involved in processing fruits is a prelude to their commercial production. As examples, the manufacture of several categories of fruit products is discussed. The final part of the book discusses individual fruits, covering their harvest to a finished product in a retail market. As a professional reference book replete with the latest research or as a practical textbook filled with example after example of commodity applications, the Handbook of Fruits and Fruit Processing is the current, comprehensive, yet compact resource ideal for the fruit industry.

This book was released on 2016-02-24 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volume presents existing and novel management approaches that are in use or have a great potential to be used to maintain the postharvest quality of fresh produce in terms of microbiological safety, nutrition, and sensory quality. In comparison to traditional synthetic chemicals, these eco-friendly molecules are equally effective with respect to slowing the physiological and biochemical changes in harvested produce. Application of terpenic compounds, phenolic compounds, salicylic acid, methyl jasmonates, hydrogen peroxide, ethanol, sulphur compounds, polyamines, plant growth regulators, active carbohydrates, ozone, hexanal and nitric oxide have been proven effective in minimizing storage disorders like chilling injury, scald, fungal diseases like stem-end rot, blue mould rot, green mould rot, anthracnose, regulation of ripening and senescence, etc. This book will be a standard reference work for the management of shelf life in the fresh produce industry.
