Ultrasound imatanthawuza mafunde opangidwa ndi makina (mafunde> 20 kHz) omwe amadutsa makutu a munthu, ndipo mtundu wafupipafupi (mafupipafupi> 100 kHz) umatchedwa high-frequency ultrasound. Mafupipafupi a zipangizo zamakono akupanga zambiri mu osiyanasiyana 20 kHz kuti 10 MHz. Monga patsogolo chakudya processing luso, ultrasound ali ndi makhalidwe ofatsa kanthu ndi amphamvu pertinence. Amagwiritsidwa ntchito kwambiri m'zakudya ndi magawo ena ndipo ali ndi chiyembekezo chachikulu cha chitukuko.
Malinga ndi pafupipafupi ndi mphamvu ya akupanga mafunde, akupanga mafunde akhoza kugawidwa m'magulu awiri: mkulu-mphamvu otsika pafupipafupi akupanga mafunde ndi otsika mphamvu mkulu-pafupipafupi akupanga mafunde. Pakati pawo, mphamvu yapamwamba yotsika kwambiri ya ultrasound (mafupipafupi pakati pa 20 ndi 100 kHz) imatchedwanso mphamvu ya ultrasound, yomwe imakhala ndi ntchito zambiri pakupanga chakudya, monga kulimbikitsa emulsification, kuwononga maselo, kutseketsa ndi kupha ma enzyme, kufewetsa nyama ndi kusinthidwa kwa zinthu, etc. Low-mphamvu high-frequency ultrasound (mafupipafupi ake amakhala makamaka mu 100 kHz mpaka 10 MHz) samangogwiritsidwa ntchito pa matenda achipatala, komanso amagwiritsidwa ntchito kwambiri pofufuza ndi kuyang'anira zakudya zakuthupi ndi mankhwala, monga kuuma, kukhwima, shuga, acidity, ndi zina zotero.
High-frequency akupanga mafunde osiyana mankhwala ndi thupi zotsatira otsika pafupipafupi akupanga mafunde, ndipo akhoza kupanga yambiri yogwira ufulu ankafuna kusintha zinthu mopitirira, potero kuchititsa kudzitsitsa ndi kusinthidwa kwa ma polima. Pamene akupanga mafunde ntchito kwa makutidwe ndi okosijeni anachita mu amadzimadzi njira, mkulu-pafupipafupi akupanga mafunde zambiri mphamvu imayenera kuposa otsika pafupipafupi akupanga mafunde. Pazifukwa zina, monga pafupipafupi limatuluka, chiŵerengero cha leni akupanga mphamvu kwa athandizira mphamvu ukuwonjezeka, ndiko kuti, kutembenuka dzuwa kumawonjezera, ndi mkulu-pafupipafupi ultrasound akhoza kukwaniritsa apamwamba sonochemical dzuwa.
Kugwiritsa ntchito katundu wa high-frequency ultrasound kungawonongenso zinthu zina zotsalira muzakudya zam'madzi otayira kapena ma CD. A ambiri yogwira ufulu ankafuna kusintha zinthu mopitirira kwaiye mkulu-pafupipafupi ultrasound angatani ndi mosavuta oxidized chakudya zosakaniza, ndi kumlingo kumapangitsanso zinchito zimatha chakudya zosakaniza.
