Inactivation of Mold Ascospores and Conidiospores Suspended in Fruit Juices by Pulsed Electric Fields

The Impact of Thermosonication and Pulsed Electric Fields on Staphylococcus aureus Inactivation and Selected Quality Parameters in Orange Juice

“…Although extensive research on orange juice treated with PEF (Raso et al 1998;McDonald et al 2000;Yeom et al 2000;Ayhan et al 2002;Roodenburg et al 2005;Cserhalmi et al 2006) has been carried out in the past, so far, no information is available on the combination of PEF and ultrasound for orange juice processing.…”

Milk thermization by pulsed electric fields (PEF) and electrically induced heat

“…It has been claimed that this novel approach has the ability to ''pasteurize'' liquid products while keeping sensory and nutritional attributes unaffected. A number of researchers (Bendicho et al, 2002;Martín-Belloso et al, 1997;Raso et al, 1998;Reina et al, 1998;Sepúlveda et al, 2009) have pointed out that PEF has great potential as a preservation treatment for liquid products such as milk (Walkling-Ribeiro et al, 2009;Craven et al, 2008) and fruit juices (Walkling-Ribeiro et al, 2008). Due to the high processing costs encountered in PEF technology, the use of thermal treatments in combination with PEF has been suggested as a strategy to increase its effectiveness and reduce costs (Hülsheger et al, 1981;Jayaram et al, 1991Jayaram et al, , 1992Zhang et al, 1994;Sepúlveda et al, 2006).…”

Effects of alternative current heating treatment on Aspergillus niger, pectin methylesterase and pectin content in tomato

“…niger is a mold found in fruits including tomato. Although, there was a lot of research on inactivation of bacteria (Reina, Jin, Zhang, & Yousef, 1998;Raso, Alvarez, Condon, & Trepat, 2000;Zhang, Chang, Barbosa-Canovas, & Swanson, 1994a;Evrendilek, Zhang, & Richter, 1999;Sastry & Barach, 2001;Cho, Yousef, & Sastry, 1999) and yeasts (Zhang, MonsalveGonzalez, Barbosa-Canovas, & Swanson, 1994b), limited literature was found on inactivation of molds (Jia, Zhang, & Min, 1999;Raso, Calderon, Gongora, Barbosa-Canovas, & Swanson, 1998) by electric field treatments such as ohmic heating and pulsed electric fields. However no published data has been found in literature discussing the effects of AC heating on A. niger, PME and pectin content of tomato fruit.…”
