Introduction

• Protein-rich diets are gaining importance since they are considered healthier, with an emphasis on the source of protein. However, with increasing concerns about health, environment and animal welfare, many consumers are interested in plant-based proteins.

• Many plant-derived proteins have been studied for their nutritional profile and sensory properties. In addition, recent studies and commercial interest have focused on oat as an excellent and economical high-protein source derived from cereals.

• Oat proteins derived from oats have a relatively higher essential amino acid content, like lysine, than other cereals, creating interest among people to consume them and leading to a market of their own.
