New trends in the food industry are radically transforming how we produce, process, and consume food, creating new pathways for personalization, sustainability, and operational efficiency. Vertical Hot Melt Extrusion (HME) is a major innovation that offers unprecedented opportunities to create highly personalized food products tailored to specific dietary needs or remote locations, including nutrient-dense options designed for individual health requirements. All of this thanks to precise control over food texture, structure, and nutrient release while improving the solubility and stability of bioactive compounds and enhancing the bioavailability of nutrients, which results in higher absorption rates of essential vitamins, minerals, and functional ingredients. Vertical extrusion enables the development of innovative functional foods, gluten-free alternatives, and plant-based meat analogues that closely mimic the texture and taste of real meat as well as many other new food applications by providing improved precision, scalability, and efficiency, making it a versatile technology for creating consistent, high-quality products across multiple food categories. Additionally, vertical extrusion is revolutionizing the production of bioactive films, a cutting-edge advancement in active packaging technology. These films interact with food, offering real-time antimicrobial and antioxidant properties that extend product freshness and shelf life. The ability to incorporate bioactive compounds within packaging also helps to reduce spoilage and waste (not only food waste but also packaging waste) and improve the overall environmental footprint of food processing. This chapter delves into the wide-ranging applications of Vertical Extrusion as a cutting-edge technology and explores its potential to shape the future of personalized and sustainable food systems on a global scale.
