Fruit Peel–Based Edible Coatings/Films

Convenience and lifestyle changes have spurred food-processing industries to produce consumable products such as fruit juices, jams, jellies, marmalades, etc. The byproducts of these fruit-processing industries are enormous, mostly the underused parts of the fruit, which are discarded as waste. Such waste includes fruit peels, seeds, rinds, pomaces, and kernels obtained during the various processing stages. These byproducts, when examined, consist of bioactive components such as dietary fibre, antioxidants, polyphenols, flavonoids, anthocyanins, etc. When these waste byproducts are properly utilised, they find diverse applications as edible coatings/films, fortified probiotics, derived metallic nanoparticles, derived carbon dots, microbiological media, biochars, derived biosorbents, etc., as discussed in the previous chapters. This chapter studies the uses of fruit peel–based edible coatings/films.
