Peas are the protein source in Jake’s shakes and bars, you can find them on the ingredient declaration as pea protein isolate. Pea Protein is obtained by a process that includes a dry and a liquid phase. First, during a drying process, the outer shell of the pea (consisting mainly of insoluble fiber) is removed. After grinding, a flour is obtained that contains soluble fiber, starch and proteins. Because pea proteins are water soluble, they can be separated from the fiber and starch by wet filtration and centrifugation. From this solution the protein isolate can be obtained, this is done by adjusting the pH of the solution so that it reaches its isoelectric point and the proteins will precipitate. The obtained protein isolate has a protein content of about 85 to 90%.
In 2018, research was conducted into the protein content and amino acid composition of commercially available vegetable protein isolates. Ten different protein sources including oats, lupine, wheat, hemp, microalgae, soy, brown rice, peas, corn and potato were compared with animal proteins, including milk, whey, caseinate, casein and egg. The essential amino acid content for pea protein was 30% this is lower than all animal proteins, but it is high enough to meet the essential amino acid requirement of the WHO / FAO / UNU Expert Consultation when pea protein is the only protein source in your diet.
These seem to us to be four very good reasons to use peas as a protein source in almost all products. Are you curious now? You can find all products on our webshop.
