The main research objectives of the group are the design and optimization of food processing conditions. Most of the work already developed is on the use of mathematical modeling of transport phenomena and quantification of degradation kinetics as two tools to optimize the final quality of thermally processed food products. Recently, we initiated a project with the main goal of studying the effects of freezing and frozen storage on orange and melon juice pectinesterase activity and quality. The main criterion to adequately pasteurize orange juice is a two decimal reduction of the activity of the enzyme. Preliminary experiments with orange and melon juices and pr...
