Integrated approach on heat transfer and inactivation kinetics of microorganism...
Gil, Maria M.; Pereira, Pedro M.; Brandão, Teresa R.S.; Silva, Cristina L.M.; Kondjoyan, Alain; Valdramidis, Vassilis P.; Geeraerd, Annemie H.The objective of this work was to create a software application (Bugdeath 1.0) for the simulation of inactivation kinetics of microorganisms on the surface of foods, during dry and wet pasteurisation treatments. The program was developed under the Real Basic 5.2 application, and it is a user-friendly tool. It integrates heat transfer phenomena and microbial inactivation under constant and time-varying temperat...
Measurement of glass transition in native wheat flour by dynamic mechanical the...
Pereira, Pedro M.; Oliveira, Jorge C.This work describes a method to study glass transition on native starch powders, based on dynamical mechanical thermal analysis using compression tests, and was applied to wheat flour (13.5% water content). This method will allow the determination of Tg in native (unprocessed) starchy materials, with minimal disturbance of the natural structures. The influence of the test conditions (heating rate, frequency and...
