Consumers have been interested in products that have
microbiological safety during production, a long shelf life, and
minimal changes in the nutritional and sensory quality of the
food . Such technologies, distinct
of traditional processes, are aimed at reducing the loss of sensitive
components, responsible for these sensory and nutritional
qualities.
Furthermore, new trends in technology should also seek to
protect the environment, showing concern for the balance between
the production and consumption of food. It is important that
technologies do not impact the environment, such as in the form of
toxic by-products. These technologies are called “emerging technologies”
or “clean technologies”.
Sound waves are generally considered safe, non-toxic, and
environmentally friendly, and this gives the use of ultrasound a
major advantage over other techniques. Studies confirming the
potential application in food industry show that these new technologies
and products should be evaluated and accepted for consumers.
This evaluation will determine the commercial success or
failure of these products. Many factors can influence the consumer’s
acceptance of food innovations. According to, the comprehension of risk-benefit perceptions of consumers,
socio-demographic and economic factors, knowledge and
information will be essential to the realization and success of
technological advances.
