Special Issue Information

Dear Colleagues,

The food industry is undergoing a profound transformation driven by the latest advancements in food science and technology. Once-revolutionary processing techniques, such as high pressure, pulsed electric fields, ultrasound, cold plasma, microwaves, and infrared, are increasingly becoming mainstream. These technologies offer promising alternatives to traditional food processing methods, offering benefits such as enhanced preservation, improved nutrient retention, and minimal thermal degradation. However, the transition from laboratory-scale applications to large-scale industrial production remains a significant challenge. Scaling up these novel techniques requires overcoming issues related to cost, consistency, and efficiency. Despite these hurdles, much of the scientific community's attention is focused on optimizing these technologies to improve food quality, safety, and shelf life. Additionally, the impact of these processing methods on the chemical characteristics, texture, flavor, nutritional value, and safety of food products is a crucial area of investigation. As these technologies evolve, they hold the potential to not only revolutionize food production but also address global challenges related to sustainability and food security. However, ensuring the safety and regulatory compliance of these innovative methods will be key to their widespread adoption in the food industry.

Extrusion cooking is broadly used in the food industry due to its easiness and simplicity. In this study a twin-screw extruder is applied at 150 rpm and 24–28 °C for the production of a nutritionally enriched extruded matrix, where hypo-allergenic rice protein (RP) and pea protein (PP) were used in the entrapment of natural antioxidant blueberry powder. The higher-moisture-content extrusion (40% MC) used with protein mixture (75 PP:25 RP) reduced the output temperature from 61.97 °C to 55 °C, the expansion ratio from 1.26 to 1, and the rehydration ratio from 78.70% to 31.90%, when compared with low-moisture-content extrusion used with RP samples (25% MC). Combining RP and PP showed also an enhancement in the textural properties of the extruded samples where firmness and toughness increased to 1503 (g) and 1822 (g.s), respectively, and preserved the anthocyanin content and antioxidant activity during extrusion processing and subsequent finish air drying. Moreover, the addition of maltodextrin in low concentration (5%) enhanced the antioxidant activity and anthocyanin retention (by 98.59% in mixture samples after extrusion and 92.13% after drying) and improved the appearance and sensory properties of the extruded matrices including firmness, toughness, and the color of the added blueberry powder.
