Book excerpt: Fruits are an important part of a balanced diet because of their high content in vitamins, minerals, dietary fiber, and bioactive compounds. Since the shelf life of fruits is limited due to microbiological, biochemical, and enzymatic reactions, processing and preservation are necessary to ensure food safety and year round availability. The present thesis aimed to investigate the effects of commonly used processing methods for fruit juice and puree production such as thermal pasteurization, alternative pasteurization (HPP, PEF), ultrasonication, and spray drying on the stability of carotenoids in goldenberry (Physalis peruviana L.) and orange (Citrus sinensis (L.) Osbeck). This thesis reveals the potential of ultrasonication as a homogenization technology that could be applied in the fruit juice industry in combination with pasteurization for the improved production of fruit juices and purees rich in potentially bioavailable carotenoids. Moreover, in comparison to commonly used carrier agents for spray drying, cellobiose showed a high potential for the application as innovative carrier material to obtain fruit juice powders with good physicochemical properties while preserving valuable constituents such as carotenoids.
