Protein concentrates are raw materials or ingredients with a relatively high crude protein content compared to the original raw material. They can come from plant sources, such as soybeans, peas, or potatoes, or from animal or microbial origins.

In animal feed, protein concentrates are used to optimize the protein level and amino acid profile of rations. They are particularly important in young animal feeds, aquafeed, and high-producing animals, where protein quality is crucial for growth, production, and health.
