Bioactive compounds in food, known for their positive health effects, can be lost during handling after harvest, processing and storage. While most foods are exposed to processing to increase shelf life and edibility and to ensure microbial safety, conventional processing methods may have disadvantages, such as decreasing the nutritional quality of foods, long processing times, high temperature and high energy uses. For these reasons, novel non-thermal food processing technologies (including HPP, ultrasound) and novel thermal food processing technologies (including microwave/Ohmic heating) have become widespread.
This book provides a critical evaluation of the effects of conventional, novel non-thermal, and thermal food processing techniques on the retention and bioaccessibility of bioactive compounds in food materials. Within these three categories, many different processing methods are included: fermentation/germination, drying, extrusion, and modified atmosphere packaging, as well as novel technologies, such as microwave heating, ultrasound, high pressure processing, ozonation, and membrane separation processes.
Prof. Seid Mahdi Jafari received his PhD in Food Process Engineering from the University of Queensland (Australia), in 2006. Now, he is a full-time Prof. of GUASNR (Iran), part-time Prof. in UVigo (Spain), and adjunct Prof. in SINANO (China). He has published > 350 papers in International Journals (h-index=64 in Scopus) and 80 book chapters/36 books with Elsevier, Springer, and Taylor & Francis. Selected achievements:
- one of the top 1% world scientists by Thomson Reuters (2015)
- one of the top national researchers by the Iranian Ministry of Science, Research, and Technology (2017)
- one of the world's highly cited researchers by Clarivate Analytics (Web of Science), in 2018, 2019 and 2020
- a top reviewer in the field of agricultural and biological sciences by Publons (2018 and 2019).

Dateiformat: PDFKopierschutz: Wasserzeichen-DRM (Digital Rights Management)
Systemvoraussetzungen:
Das Dateiformat PDF zeigt auf jeder Hardware eine Buchseite stets identisch an. Daher ist eine PDF auch für ein komplexes Layout geeignet, wie es bei Lehr- und Fachbüchern verwendet wird (Bilder, Tabellen, Spalten, Fußnoten). Bei kleinen Displays von E-Readern oder Smartphones sind PDF leider eher nervig, weil zu viel Scrollen notwendig ist. Mit Wasserzeichen-DRM wird hier ein „weicher” Kopierschutz verwendet. Daher ist technisch zwar alles möglich – sogar eine unzulässige Weitergabe. Aber an sichtbaren und unsichtbaren Stellen wird der Käufer des E-Books als Wasserzeichen hinterlegt, sodass im Falle eines Missbrauchs die Spur zurückverfolgt werden kann.
