Macroalgae

In parallel, our lab is also dedicated to exploring the potential of macroalgae, or seaweeds, as a renewable source of biomaterials with significant applications in food packaging. Macroalgae offer a promising solution to the growing problem of plastic waste, as they can be used to produce biodegradable and edible films. These films can serve as alternatives to conventional petroleum-based plastics, offering a sustainable option for the food industry. We are particularly focused on the development of edible films derived from macroalgae, which have potential uses in food packaging to reduce plastic pollution. These films are not only biodegradable but also possess functional properties, such as moisture retention, antioxidant activity, and antimicrobial effects, which are crucial for preserving food quality. By leveraging the unique polysaccharide composition of macroalgae, such as alginate, carrageenan, and agar, we develop films with tailored mechanical strength, barrier properties, and biodegradability. Our research emphasizes the formulation and processing of these films through eco-friendly and scalable methods, while also exploring the incorporation of bioactive additives (e.g., antioxidants, antimicrobials) to enhance their functionality. We also examine how various processing techniques, such as cross-linking and blending with other natural biopolymers, can enhance the mechanical strength and barrier properties of these films. By advancing the use of macroalgae for sustainable packaging materials, we aim to contribute to a circular bioeconomy and reduce the environmental footprint of the packaging industry.
