Although ultrasound has proven to be a very effective innovative technique of food processing, being
applicable to many processes for instance in the emulsification, crystallization, homogenization, cutting,
hydrolysis, extraction and microbial inactivation, among other techniques that imply ultrasounds
exposure. Although this promising technique has presented innumerous advantages over conventional
techniques, some food products seem to present certain alterations after exposure to ultrasound and
these possible effects and consequences to products quality are often overlooked. In this review, some of
the effects induced by ultrasound on food products in general and more specifically on high lipid containing
food material are presented, evidencing the degradation of some compounds and the modifi-
cations in physicochemical parameters of food products.
