What are pea protein and whey protein? 

Pea protein is a plant-based protein obtained from yellow split peas. The extraction process generally involves two phases:

  1. Dry phase- In this stage, the peas are dried and then grounded into a fine powder which is filled with protein, starch and fibre. 
  2. Liquid phase- The powder obtained from the dry phase is then mixed with water so that the fibre and starch can be separated.

Pea protein is found in concentrate and isolates forms. However, the isolate form of pea protein is considered to have more fibre and starch content. Pea protein is a complete protein, i.e., they contain all the nine essential amino acids that are needed by the body for the proper functioning of the system. The nutrients present in a 100gram serving of pea protein are:

  1. Protein- 1.15grams
  2. Carbohydrates- 3grams
  3. Fibre- 1gram
  4. 80 calories
