At present, the UPV comprises 13 university centers, of which nine are higher technical schools, two are faculties and another two, higher polytechnic schools. In addition, it has a Doctoral School and three affiliated centres (Florida University, Berklee College of Music and EDEM Business School).

Overview of research activities of ASPA group (UPV)

The researchers of Universitat Politècnica de València involved in MEFPROC project are members of the research group ASPA (Analysis and Simulation of Agro-Food Processes), located in the Department of Food Technology. This group began its activities in 1991 and has as a main objective the analysis and optimization of agrofood processes (energy, environment, economics, production..). To this end, processes are characterized, designed and controlled by operation modelling and simulation using computer tools. Not only are conventional processes such as drying or thermal treatments considered, but new technologies like supercritical fluid extraction, high power ultrasonics and PEF and MEF are also investigated. Product assessment involves the classical physico-chemical analysis as well as the use of new techniques based on ultrasonics (non-destructive) or electromyography.

Areas of research focus in MEFPROC project

The participation of UPV in MEFPROC is mainly involved with the design and develop a high performance, flexible and reliable ultrasonic prototype and its integration in a MEF system. The combined (simultaneous or sequential) US and MEF application will be evaluated in volumetric heating or extraction/impregnation processes in terms of kinetics, quality of products and energy consumption. Modifications in the prototype will be considered to improve processing, the security or the feasibility to scale-up.

Technische Universität Berlin (TUB)

The Technische Universität Berlin (TUB) is one of four universities in Berlin. Currently, TUB has 7830 employees and 360 professorships. About 35 000 students are enrolled in more than 120 study programs. Research activities are focusing on the six key application areas Digital Transformation; Energy Systems, Mobility, and Sustainable Resources; Human Health, Humanities, and Educational Science; Urban Systems and Environmental Systems; Photonics and Optical Systems, Materials, Design and Manufacturing

Detail of research activities at TUB University:

The department of food biotechnology and food process engineering of TUB has more than 20 years of experience in innovative food processing including electric fields and high power ultrasound. Activities focus on mass transfer improvement, gentle preservation techniques, and stress induction for enhanced secondary metabolite production as well as process optimization via experimental and numerical approaches. A lot of research is performed within the field of fruit and vegetable processing in regard to product quality and process efficiency. The department has several units for electro- and ultrasound processing up to pilot plant scale as well as extensive equipment for processing and analysis of fruit material. 

Areas of research focus in MEFPROC:

The task of TUB is to evaluate the potential of moderate electric fields (MEF) and high power ultrasound (US) to improve mass transport operations in fruit processing. Therefore, the entire process chain of fruit processing is regarded and the innovative technologies are applied in different stages of the process chain to figure out their optimal application areas. Apples and berries serve as raw materials. Investigations are performed in laboratory and pilot plant scale and results compared to conventional thermal treatments and high intensity electric pulses in regard to product quality and process efficiency.

The first step in the processing chain, in which MEF is applied, is the production of fruit juices. MEF treatment will be used to facilitate solid-liquid separation resulting in less press residue, and to increase the extraction of valuable vitamins and secondary metabolites during pressing to positively affect color and antioxidant properties of the fruit juice.

MEF effects are also used to improve extraction of pigments and secondary metabolites from fruit press cakes. Pectin recovery from by-products of juice manufacturing is usually performed at acid pH-values and high temperatures. Here, the application of MEF may be an effective alternative to indirect heating methods. Both extraction procedures may further be improved by the additional usage of ultrasound for enhanced mass transport.

The residual material remaining after pectin extraction is rich in insoluble dietary fibers which gain more and more interest as nutritional additives and techno-functional compounds in fat and sugar reduced food products. As techno-functionality of fibers exhibits marked shear sensitivity, application of ultrasound in previous processing stages may affect water binding capacity and rheological behavior of the plant fibers. The influence of MEF and US is therefore as well investigated with regard to functional fiber properties.
