Green beans temperature was monitored inserting a thin
thermocouple probe (103m in diameter)under the external surface
of green bean samples. Measurements showed that, when the
temperature of the sample before treatment was about 20 C, the
temperature of the sample after the most intense treatment
(1.2
105 J/m2 foreach sideof the greenbeans)neverexceeded 30 C.
Samples were then stored in the same sterile pouches used for
HHP treatment, with an open end, and stored at 4 C, in analogous
conditions to HHP-treated samples.
