Modeling Maillard Reaction and Thermal Transformations During Bread Baking

D. Papasidero[1], F. Manenti[1]
[1]Politecnico di Milano, Dipartimento di Chimica, Materiali e Ingegneria Chimica “Giulio Natta”, Milano, Italy

One big challenge for the food industry is to predict and optimize flavors. The Maillard reaction occurs in food matrices containing carbohydrates and proteins under specific operating conditions. The presented research couples thermal and kinetic modeling to the bread baking process, ... Mehr lesen

Modeling of Fluid Flow and Heat Transfer During a Steam-Thermolysis Process for Recycling Carbon Fiber Reinforced Polymer

A. Oliveira Nunes[1], Y. Soudais[1], R. Barna[1], A. Bounacer[1], Y. Yang[1]
[1]Centre RAPSODEE - Ecole des Mines d'Albi, Albi, France

Different types of technologies to recycle carbon fiber reinforced polymer (CFRP) waste have been studied, for example: pyrolysis, solvolysis and steam-thermolysis. The steam-thermolysis is a process that combines pyrolysis and superheated steam at atmospheric pressure to decompose the ... Mehr lesen

Modeling of Coupled Mass and Heat Transfer and Expansion During Baking of Bread in a Mould

V. Nicolas[1], C. Doursat[2], D. Grenier[1], T. Lucas[1], D. Flick[2]
[1]Institut de recherche en sciences et technologies pour l'environnement et l'agriculture, Rennes, France
[2]AgroParisTech, UMR1145 Ingénierie Procédés Aliments, Massy, France

Bread is a food product which various complex physico-chemical phenomena occur during the cooking process. Thus, phenomena of heat and mass transfer are coupled to the deformation. In addition, bread is a multiphase product (solid, liquid and vapor) and composed of various components ... Mehr lesen

Numerical Simulation of a Rotary Desiccant Wheel

G. Diglio[1], P. Bareschino[1], G. Angrisani[1], M. Sasso[1], F. Pepe[1]
[1]Università degli Studi del Sannio, Benevento, Italy

The core unit of desiccant cooling systems is a dehumidifying device, in most cases a wheel made of inert material coated with an adsorbent (silica gel in the present work). Two sections can be identified: air to be dehumidified was passed through the process section, while in the ... Mehr lesen

Modelling the Response of Microdialysis Probes in Glucose Concentration Measurement

J.M. Gozálvez-Zafrilla[1], A. Santafé-Moros[1], J.L. Díez-Ruano[2], J. Bondia[2]
[1]Institute for Industrial, Radiophysical and Environmental Safety (ISIRYM) - Universitat Politècnica de Valencia, Valencia, Spain
[2]Instituto Universitario de Automática e Informática Industrial (AI2) - Universitat Politècnica de Valencia, Valencia, Spain

Microdialysis is a technique of continuous glucose monitoring in diabetic patients. In microdialysis, a saline serum is perfused into a microdialysis probe. Glucose pass from the plasmatic fluid through the porous membrane. The glucose concentration in the dialysate obtained is measured ... Mehr lesen

Numerical Simulation of Concentration Polarization to Estimate Gypsum and Calcium Carbonate Scaling on Membrane Surfaces

A. Santafé-Moros[1], J.M. Gozálvez-Zafrilla[1]
[1]Institute for Industrial, Radiophysical and Environmental Safety (ISIRYM) - Universitat Politècnica de Valencia, Valencia, Spain

This paper shows a model to estimate the scaling parameters for reverse osmosis membrane processes. The model takes into account the concentration polarization of ionic species in the membrane channel of spiral-wound modules and the effect of the spacers on the flow. The scaling ... Mehr lesen

Modeling and Simulation of Dielectric Barrier Discharge Plasma Reactor for Nitrogen Fixation Reaction

B.S. Patil[1], Q. Wang[2], V. Hessel[2], J. Lang[3]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands
[2]Micro Flow Chemistry and Process Technology, Eindhoven University of Technology, Eindhoven, The Netherlands
[3]Innovation Management, Verfahrenstechnik & Engineering, Evonik Industries AG, Hanau-Wolfgang, Germany

Fixed nitrogen is used in many forms ranging from nitric acid to hydrogen cyanide and is used as such for industrial applications. The reactions to produce these products are highly endothermic and favored by high-temperature processing. The most basic route of chemically fixing nitrogen ... Mehr lesen

Food Cooking Process. Numerical Simulation of the Transport Phenomena

B. Bisceglia[1], A. Brasiello[1], R. Pappacena[1], R. Vietri[1]
[1]University of Salerno, Department of Industrial Engineering, Fisciano (SA), Italy

Aim of the study is to determine the influence of some of the most important operating variables, especially humidity and temperature, of drying air on the performance of cooking process of pork meat. The process is simulated using finite elements software COMSOL Multiphysics®. The ... Mehr lesen
