Opportunities for the valorization of waste generated by the plant-based milk substitutes industry

Waste generation by the food industry is an alarming problem. Consumption of plant-based beverages is increasing considerably, making this sector of the industry more relevant, especially owing to the high residue generation. Increasingly, attempts are being made to reduce it through revaluation and reuse of byproducts in different ways. In this chapter a literature review has been carried out on the byproducts nature, composition, properties, and possible uses of these wastes. It has been proved that these products have both an interesting nutritional composition and a wide range of applications in the development of new products besides the fortification of traditional foods. Meat products, emulsions, and gluten-free products, dairy products are just some of the many sectors in which byproducts from the vegetable beverage industry play an important role. The results demonstrate the great potential of these byproducts in the food industry and encourage further study of their functional and technological properties.
