Protein concentrate has the largest share in the plant protein market. Concentrates have become a popular choice over isolates because of the same nutritional profile but at lower costs. This segment is driven by its extensive use in food industries such as the functional food and beverage sector owing to its potential benefits such as high-water solubility, fat-binding capacity, emulsifying properties, and foaming ability.  Also, protein concentrates are available in different forms, such as granules, flakes, flour, and spray-dried powders. Concentrated proteins have also found use in injection-molded chews and treats. Furthermore, rapid advancements in technology and companies’ efforts in trying to develop products with multifunctional uses are driving the trend of protein concentrate in Spain.​
