The protein type is a description used in the food industry to describe the differences in the origin of the protein (e.g. animal based or plant based) or behavioural characteristics of a protein (mixture). The main difference between animal and plant proteins is their amino acid profile.

Most animal proteins are complete proteins, meaning they contain all 9 of the essential amino acids (EAAs). Most plant proteins are considered incomplete proteins, meaning they are missing at least one essential amino acid. However, eating multiple plant proteins together can create the effect of complete proteins.

In order to meet the sustainability goals, the protein transition (change from animal to plant proteins) is taking place right now. The challenge for food producers is to deliver plant-based protein ingredients and applications that are tasty, healthy, stable, safe and sustainable.
