Abstract

Collagen, the principle structural protein of multicellular organisms, is now growing as a vital ingredient in the food, pharmaceutical, and biomedical industries. Owing to its versatile properties, collagen products have gained a significant market value, forecasting an increasing demand (a rise in CAGR of 5.05% in next few years) in the global collagen industry. This pressurising demand cannot be satisfied with the conventional (bovine, porcine, and marine) sources, amid their shortcomings. Studies have shown that a novel and practically suitable source of collagen can be obtained using slaughter wastes from the poultry industry as a substitute for the traditional collagen sources. Products of the poultry industry (consumables- meat and eggs; discards- feather, skin, offal, and droppings) exhibit their utility in diverse applications, as poultry are rich in high quality protein and desirable fatty acids reports. During the past decades, the avian derived collagen is observed to be used in industries including food, tissue engineering and cosmetic applications. Hence, the poultry spent wastes are taken as the element of discussion, focussing on aspects like extraction, characterization methods, and applications.
