The novel processing technologies, especially their applications in food, raise many issues like nutritional status, food quality, economics involved, and consumer acceptance. These issues need to be addressed initially in technology improvement and development. However, whether extensive assessment of consumer acceptance is necessary for all food-related technologies is uncertain. A review of food processing-related technologies associated with different levels of public acceptance suggests that those characterized as being “bioactive” raise particular concerns related to unpredictable effects, uncontrolled use, and ethical concerns.
