1. Applications of Microwave Heating of Foods
Abstract : AbstractMicrowave heating of foods offers rapid and flexible heating both for consumer and industrial applications, with several advantages, such as reduced processing time (due to volumetric heating and reduced coming-up times (heating time required to reach the desired target temperature), selective heating, increased process flexibility and efficient heating (volumetric heating of the food does not require heating of a surrounding medium or package). However, successful installations requireknowledge in process design. READ MORE

4. Microwave-Assisted Air-Dehydration of Fruits and Vegetables Processing Conditions and Product Quality
Abstract : This thesis is focused on aspects of microwave-assisted hot-air drying of fruits and vegetables. The two material coefficients, the relative permittivity (ε) and the loss factor (ε), determine the interaction of microwave energy with foods. READ MORE

5. Synthesis and asymmetric transformations of diols by enzyme- and ruthenium catalysis
Abstract : The major part of this thesis describes the synthesis of aliphatic secondary diols and the development of lipase- and ruthenium-catalyzed asymmetric transformations of these diols. Several acyclic 1,4-diols and 1,5-diols were synthesized, and by combining a lipase-catalyzed asymmetric transformation with a ruthenium-catalyzed epimerization, enantiomerically- and diastereomerically enriched diacetates were obtained.
