“…A study measured ultrasound attenuation and velocity in some Moroccan oils like argan oil, olive oil, and commercial cooking oils using the pulse-echo technique. Acoustical data was determined by the processing of data for the oils such as absorption loss coefficient, celerity, acoustical impedance, compressibility modulus, and density [122] . Acoustic energy also helps in the extraction of pesticide residue by virtue of its chemical and physical effects significantly.…”
