    The progress of malolactic fermentation in red wines has been monitored by using ultrasonic techniques. The evolution of ultrasonic velocity of a tone burst 1 MHz longitudinal wave was measured, analyzed and compared to ...
  • Ultrasonic velocity of water-ethanol-malic acid-lactic acid mixtures during the malolactic fermentation process 

    Amer, M.A.; Novoa Díaz, Daniel F.; Puig-Pujol, A.; Capdevila, Josefina; Chávez Domínguez, Juan Antonio; Turó Peroy, Antonio; García Hernández, Miguel J.; Salazar Soler, Jorge (Elsevier, 2015-03)
    Article
    Open Access
    During malolactic fermentation in wines, malic acid is transformed into lactic acid by the action of lactic acid bacteria. This process can be monitored on-line by measuring the velocity of a low intensity ultrasonic wave ...
  • Zero-flow offset variation in ultrasonic clamp-on flowmeters due to inhomogeneity and nonlinearity of pipe materials 

    Millán Blasco, Oliver; Salazar Soler, Jorge; Chávez Domínguez, Juan Antonio; Turó Peroy, Antonio; García Hernández, Miguel J. (2017-11)
