Process for liquid food preservation using pulsed electrical field treatment
The present invention relates to a process for fast and homogeneously heating a liquid product to a predetermined temperature by means of resistive heating. Sufficient and effective microbial inactivation is achieved upon applying an electrical field strength of between 0.1-5.0 kV/cm for a prolonged period of time, thus by selecting a relatively low electrical field strength and a pulse duration of at least 10 microseconds while the maximum temperature of the liquid product autonomously remains below 92 C. during the resistive heating. The present invention further relates to said process wherein the liquid product is pre-heated prior to subjecting the liquid product to the process. The present invention also relates to the liquid product obtainable by the process according to the invention.
Process for fast and homogeneously heating a liquid product and apparatus for such process
The invention relates to an apparatus for fast and homogeneously heating a liquid product to a heating temperature by means of resistive heating, the apparatus comprising at least two vertically mounted, longitudinal, heating chambers that are arranged in series. The invention further relates to a process for fast and homogeneously heating a liquid product to a heating temperature by means of resistive heating in such apparatus comprising (a) continuously supplying the liquid product to the first heating chamber in series and flowing the liquid product continuously through the at least two heating chambers; (b) continuously generating an electrical current through the liquid product flowing through the heating chambers by continuously applying an electrical potential over each heating chamber, wherein the direction of the current is continuously alternated with a frequency of at least 500 Hz, to obtain heated liquid product; and (c) continuously discharging heated liquid product from the last heating chamber in series, wherein the liquid product has an electrical conductivity of at least 0.03 S/m.
