Inactivation of <i>Lactobacillus brevis</i> in Liquid Egg White by Radio-Frequency Flash Heating
Access this Article
An electric pasteurizer utilizing Radio-Frequency Flash Heating (RF-FH) was constructed in order to pasteurize liquid egg white. This pasteurizer inactivated <i>Lactobacillus brevis </i>in liquid egg white using a radio-frequency electric field. RF-FH enabled inactivation of <i>L. brevis </i>at 60°C in 2.4 s equally well as conventional heating at 54°C for 29.5 min. The shorter heating time yielded higher quality liquid egg white. A foam made from RF-FH treated egg white maintained its strength similarly to untreated egg white, but foam made from liquid egg white conventionally heated at 54°C for 29.5 min showed reduced strength.
