The low toxicity and mechanical flexibility of sodium alginate have made it an excellent choice for the preparation of new-generation edible coatings in recent years. This quest for sustainable solutions has opened the field of biopolymers, with one such option being sodium alginate as a polymer. Current research trends explore the techno-functional properties of sodium alginate and have been extended to include film formability, gas permeation, and mechanical attributes as necessary determinants that govern coating performance. The synergy between the techno-functional and bioactive landscapes enables sodium alginate to play a multifaceted role in tailor-made coatings that are associated with diverse fruits while catering to on-shelf stability, final product elegance, and appealing to evolving trends of sustainably sourced health-conscious food choices. This review explores the novel potential of sodium alginate-based formulations in controlled bioactive release, enhanced antioxidant properties, and its role in nutrient retention.

Among emerging innovations, aptamer-based biosensors (aptasensors) offer increased sensitivity and reduced detection times compared to traditional methods for identifying <i>E. coli</i> O157: H7. Aptamers, short single-stranded DNA (ssDNA) or RNA molecules, act as bio-recognition elements, exhibiting high specificity and affinity for foodborne pathogens.
