Metal release in a stainless steel pulsed electric field (PEF) system

The Impact of Nonthermal Technologies on the Microbiological Quality of Juices: A Review

“…A significant increase in metal contents, such as Fe, Zn, Mn, and Cr have been observed in beer treated with PEF (Evrendilek, Li, Dantzer, & Zhang, ). Long PEF treatment time triggered metal corrosion (Roodenburg, Morren, Berg, & de Haan, ). The high capital cost is another main concern that has limited interest in this technique.…”

Pulsed electric field technology in the manufacturing processes of wine, beer, and rice wine: A review

“…Specifically, the result of the experiment showed that after 3 h of repeatedly circulating a sodium chloride concentration to the sample, the detection limits of iron, chromium, nickel, and manganese, which were 14, 2, 3, and 2 mg L À1 , respectively, were all within acceptable levels. However, with the PEF treatment, the dissolution of the metal was more intense especially for iron, and the concentrations were 28.29, 14.04, and 359.64 mg/L, respectively, for three PEF treatments with three different pulses for 3 h (Roodenburg, Morren, Berg, & de Haan, 2005). Apparently, metal corrosion became more intense with increasing time.…”

Aplicación industrial de los pulsos eléctricos de alto voltaje para la pasteurización de alimentos: revisión de su viabilidad técnica y comercial

“…Algunos de los materiales recomendados para la fabricacio´n de los electrodos son el acero inoxidable, el grafito o el titanio, mientras que para el aislante, cera´micas o polı´meros pla´sticos. Sin embargo, debido a la transmisio´n de la corriente ele´ctrica entre los electrodos siempre existe cierto paso de mole´culas del electrodo al alimento y viceversa (Morren, Roodenburg, & de Haan, 2003;Rodenburg, Morren, Berg, & de Haan, 2005a, 2005b. Ası´, en la actualidad se esta´investigando el uso de recubrimientos de diversos materiales pla´sticos o cera´micos para evitar, o al menos minimizar, esta clase de problemas (Pizzichemi, 2009;Rodenburg et al, 2010).…”
