Combined effects of pulsed electric field, Chamuang leaf extract and cold plasma on quality and shelf-life of Litopenaeus vannamei

Abstract Pulsed electric field (PEF) pre-treated Litopenaeus vannamei were immersed in Chamuang leaf extract (CLE) solutions (1 or 2%), followed by high voltage cold atmospheric plasma (HVCAP) in an argon/air (80:20) modified atmosphere for 10 min. Least melanosis scores were attained in the samples pre-treated with PEF (15 kV/cm, 800 pulses, 697 kJ/kg) and CLE (2%) prior to HVCAP compared to the untreated control, during 18 days at 4 °C (P
