Handbook Tecnologías Emergentes Aplicadas en Alimentos

Abstract

Nowadays, emerging technologies for food are the most studied, compared to the traditional food preservation. In this book some of the emerging technologies applied in the food industry are revised, such as irradiation that allows to improve food safety and shelf life; the advantages and some limitations of technology are presented, as well as the effects on the food properties and the applicable legislation for human consumption. A comparison of the emerging technologies combined with high hydrostatic pressure treatment is conducted. On the other hand, active packaging technology is described: its principles, advantages and disadvantages. Another technology that is presented is the ultrasound, with its basic concepts, applications and sustainability. The application of ozone technology in food usage and its environmental impact is also described. Moreover, the functioning of pulsed electric fields is explained, its effect and the microbial inactivation process on food.
