Abstract
We herein provide an overview of the most recent multidisciplinary process advances that have occurred in the food industry as a result of changes in consumer lifestyle and expectations. The demand for fresher and more natural foods is driving the development of new technologies that may efficiently operate at room temperature. Moreover, the huge amount of material discarded by the agro-food production chain lays down a significant challenge for emerging technologies that can provide new opportunities by recovering valuable by-products and creating new applications. Aiming to design industrial processes, there is a need for pilot scale plants such as the ‘green technologies development platform’, which was established by the authors. The platform is made up of a series of multifunctional laboratories that are equipped with non-conventional pilot reactors, developed in direct collaboration with partner companies, in order to bridge the enormous gap between academia and industry via the large-scale exploitation of relevant research achievements. Selected key, enabling technologies for process intensification make this scale-up feasible. We make use of two selected examples, the grape and olive production chains, to show how cavitational reactors, which are based on high-intensity ultrasound and rotational hydrodynamic units, can assist food processing and the sustainable recovery of waste, to produce valuable nutraceuticals as well as colouring and food–beverage additives.
Highlights
Extraction is one of the essential food industry processes in the preparation of key ingredients.The choice of technology and procedure has a significant impact on food and beverage quality.A number of lab-scale and innovative protocols that make use of emerging technologies for food extraction and processing have been reported [1,2,3,4,5]

Summary
Extraction is one of the essential food industry processes in the preparation of key ingredients. Is worth mentioning the Valréas extraction platform (PEEV), a technical structure grouping equipment and expertise for R &for. In order to help bridge the gap between academyand andlarge-scale large-scaleproduction, production,the theauthors, authors,a chemists, technologists, andand process engineers, havehave worked together to set to upset theup ‘green agroup groupofof chemists, technologists, process engineers, worked together the technologies development platform’, which brings together research, R and. The reproduction of of laboratory, laboratory, gram-scale gram-scale data data in in pilot, pilot, kilogram-scale kilogram-scale reactors reactors was was aa expertise This strategy strategy enabled enabled the the primary primary heat heat and and mass mass transfer transfer data data to to be be obtained, obtained, challenging and a potential industrial plant to be designed.
