The quality of meat from different animal species is defined by chemical, physical sensory and microbiological characteristics, which can be influenced by procedures during the slaughter of animals. Technologies such as ultrasound (US) and slightly acidic electrolyzed water (SAEW) are being studied in order to assist in food processing and in developing methods that are economically viable and environmentally sustainable. The aim of this paper is to discuss the relationship between US and SAEW in relation to tenderness, microbiology, and oxidation of meat. The meat industry was a pioneer in the use of the ultrasound, which initially aimed to determine the layer of fat on carcasses and subsequently improve the tenderness of the meat. Recently studies mention that the ultrasound and SAEW can influence the microbiological parameters. The combination of both technologies should also be considered, with the possibility of enhancing the antimicrobial effects. However, there is little information regarding oxidative parameters promoted in meat for these two alternative technologies, where the individual or when interspersed use. Knowing the actions and consequences of ultrasound and SAEW in meat will enable the opening of new perspectives about the application of these technologies in the meat industry.
