Ultrasound as an alternative to conventional marination: Acceptability and mass transfer

Abstract

In this study, the effects of ultrasound- (US-) assisted beef marination on consumer perception and the homogeneity of the solute and mass transfer were evaluated. Marinated and US-treated meat samples (40kHz, 11W/cm2 for 20, 40, and 60min, and storing at 4°C for 7d) were evaluated by a group of consumers using a structured 9-point hedonic scale of satisfaction. The preferences were analyzed with XLSTAT-Sensory® software. The analysis was performed in conjunction with an energy-dispersive X-ray spectroscopic study to evaluate the sodium transference. The perception analysis indicated that the use of US-assisted marination did not increase the beef acceptability. The sonicated samples showed a more homogeneous distribution of sodium. However, traditional marination (TM) stored for 7d resulted in greater mass transfer than the US-assisted marination without storage.
