Model w1/o/w2 emulsions with possible uses as functional foods were therefore prepared. These w1/o/w2 emulsions contained colostrum as the internal water phase w1; howeveralthough colostrum has high nutritional value 1 more it is a very sensitive material. Emulsions were therefore prepared using a sensitive two-step emulsification process. Model w1/o/w2 emulsions were characterized after preparation and then over a 4 wk (week) period.

Impact of formulation, processing technology and storage on anthocyanins, proteins and their interactions in complex systems AuthorAnna-Sophie Stübler Year2022 SourceDIssertation LanguageEnglish Pages1-150 2684LSLUMiSizerZiel der vorliegenden Doktorarbeit war die Untersuchung der Auswirkungen der Formulierung und der alternativen und traditionellen Verarbeitungstechnologien auf komplexe Lebensmittelsysteme mit einem Schwerpunkt auf der Stabilität und Bioverfügbarkeit von Anthocyanen und Proteinen. Gezielt formulierte Lebensmittelsysteme 11 more bestehend aus einer anthocyanreichen Matrix (Erdbeere) und einer relativ proteinreichen Matrix (Grünkohl) und deren Behandlung mit den verschiedenen Verarbeitungstechnologien (thermischPEF und HPP) können zu einem unterschiedlichen Ausmaß an Anthocyan-Protein Interaktionen führen und die Stabilität und Bioverfügbarkeit von Anthocyanen und Proteinen nach der Behandlung und während der gekühlten Lagerung beeinflussen. Um den Mechanismus hinter den beobachteten Ergebnissen besser zu verstehenwurde zusätzlich eine Studie in einem Modellsystem mit Anthocyanen und einem gereinigten Protein durchgeführt. Die hier genannte Bioverfügbarkeit ist definiert als die von der Lebensmittelmatrix freigesetzte Fraktion eines Inhaltsstoffeswelcher für die Absorption im Verdauungstrakt verfügbar ist.This doctoral thesis aimed to understand the effects of formulation and alternative (PEFHPP) compared to traditional thermal processing on complex food systemsfocusing on the stability and bioaccessibility of anthocyanins and proteins. It was hypothesized that targeted formulation of food systems consisting of an anthocyanin-rich matrix (strawberry)and a relatively protein-rich matrix (kale)treated with selected processing technologies (thermalPEFHPP) resulting in a minimum 5-log microbial reduction can lead to a different extent of interactions between the polyphenols and proteins and can affect the stability and bioaccessibility of anthocyanins and proteins after the treatment and during refrigerated storage. For an enhanced mechanistic understanding of the results in the complex systema concise study on a model system containing anthocyanins and a purified protein treated with the processing technologies was conducted.In vitro digestion · Antioxidant capacity · Pulsed electric fields (PEF) · High-pressure processing (HPP) · Protein More details LocationFakultät III - Prozesswissenschaften der Technischen Universität Berlin, Germany Internal reference2684 Open publication →
