ʻO ke kani kani i ka hawewe mechanical (frequency>20 kHz) i ʻoi aku ma mua o ka lohe ʻana o ka pepeiao o ke kanaka, a ʻo ke ʻano alapine kiʻekiʻe (frequency>100 kHz) ua kapa ʻia ʻo ultrasound high-frequency. ʻO ke alapine o nā mea kani ultrasonic o kēia manawa aia ma ka laulā o 20 kHz a 10 MHz. Ma ke ʻano he ʻenehana hoʻomaʻamaʻa meaʻai kiʻekiʻe, loaʻa ka ultrasound i nā hiʻohiʻona o ka hana maʻalahi a me ka pili ikaika. Hoʻohana nui ʻia ia i ka meaʻai a me nā māla ʻē aʻe a loaʻa nā manaʻo hoʻomohala nui.
E like me ke alapine a me ka mana o nā hawewe kani ultrasonic, hiki ke hoʻokaʻawale ʻia nā hawewe kani ultrasonic i ʻelua ʻano: nā hawewe kani ultrasonic haʻahaʻa haʻahaʻa haʻahaʻa a me nā hawewe kani ultrasonic haʻahaʻa haʻahaʻa. I waena o lākou, kiʻekiʻe-mana haʻahaʻa haʻahaʻa ultrasound (frequency ma waena o 20 a me 100 kHz) ua ike no hoi i ka mana ultrasound, i ka laulā huahelu o nā noi i loko o ka meaʻai hana, e like me ka paipai 'ana i ka emulsification, e luku ana i nā pūnaewele, sterilization a me ka enzyme pepehi, softening io a me ka waiwai hoʻololi, etc. Low-mana kiʻekiʻe-frequency ultrasound (ʻo kona alapine i ka nui i loko o 100 kHz a hiki i 10 MHz) ʻaʻole i hoʻohana wale ʻia i ka maʻi maʻi, akā ua hoʻohana nui ʻia i ka nānā ʻana a me ka nānā ʻana i nā meaʻai kino a me nā waiwai kemika, e like me ka paʻakikī, ka makua, ke kō, acidity, etc.
Loaʻa i nā hawewe kani ultrasonic kiʻekiʻe nā kemika a me nā hopena kino mai nā hawewe kani ultrasonic haʻahaʻa, a hiki ke hoʻoulu i ka nui o nā radical manuahi ikaika, a laila e hoʻohaʻahaʻa a hoʻololi i nā polymers. Ke hoʻohana ʻia nā hawewe kani ultrasonic i ka hopena oxidation i loko o kahi hopena wai, ʻoi aku ka ikaika o nā hawewe kani ultrasonic kiʻekiʻe ma mua o nā hawewe kani ultrasonic haʻahaʻa. Ma lalo o kekahi mau kūlana, e like me ka alapine (frequency) piʻi, ka lākiō o ka maoli ultrasonic ka mana i ka hoʻokomo mana hoʻonui, 'o ia hoʻi, ka hoʻololi 'ana ka pono mahuahua, a kiʻekiʻe-frequency ultrasound hiki ke hoʻokō i ka sonochemical pono kiʻekiʻe.
ʻO ka hoʻohana ʻana i kēia waiwai o ka ultrasound kiʻekiʻe hiki ke hoʻohaʻahaʻa i kekahi mau mea ʻino i loko o ka ʻoihana meaʻai wai ʻōpala a i ʻole ka pahu. Hiki i ka nui o nā radical manuahi ikaika i hana ʻia e ka ultrasound kiʻekiʻe hiki ke hana me ka maʻalahi o ka meaʻai meaʻai, a i kekahi ʻano hiki ke hoʻonui i nā waiwai hana o kekahi mau meaʻai.
