Special Issue Information

Dear Colleagues,

Food-grade immobilisation systems for enzymes have received increasing attention in recent years. Immobilisation techniques involve physically confining enzymes to a specific region while preserving their catalytic capabilities. This approach enables the use of enzymes in optimal micro-environments and conditions. It enhances their properties by modifying various catalytic features, such as specificity, selectivity, and stability, across a range of pH and temperature conditions, encouraging inhibitor resistance and offering the possibility of recyclability over multiple catalytic cycles.

Additionally, stable immobilised biocatalyst systems simplify enzyme separation from the reaction medium, mitigate or completely prevent product contamination, enable continuous operations, and facilitate enzyme application in diverse types of reactors. The potential advantages and suitability of immobilised enzymes in the food industry, including their application in active food packaging, enzymatic biosensors, and food ingredients, have prompted numerous investigations in this field.

This Special Issue will attempt to bring together food scientists, food engineers, and packaging technologists from around the world who are working on innovative immobilisation systems of enzymes for food applications, presenting the state of the art in this emerging field of science and technology.

The use of enzyme immobilisation is becoming increasingly popular in beverage processing, as this method offers significant advantages, such as enhanced enzyme performance and expanded applications, while allowing for easy process termination via simple filtration. This literature review analysed approximately 120 articles, published on the Web of Science between 2000 and 2023, focused on enzyme immobilisation systems for beverage processing applications. The impact of immobilisation on enzymatic activity, including the effects on the chemical and kinetic properties, recyclability, and feasibility in continuous processes, was evaluated. Applications of these systems to beverage production, such as wine, beer, fruit juices, milk, and plant-based beverages, were examined. The immobilisation process effectively enhanced the pH and thermal stability but caused negative impacts on the kinetic properties by reducing the maximum velocity and Michaelis–Menten constant. However, it allowed for multiple reuses and facilitated continuous flow processes. The encapsulation also allowed for easy process control by simplifying the removal of the enzymes from the beverages via simple filtration, negating the need for expensive heat treatments, which could result in product quality losses.
