There are many options nowadays to obtain protein supplementations for various reasons such as to increase muscle growth, recovery, endurance as well as weight loss. For many decades, egg protein or egg white from animal source have been known to contain the highest protein quality as well as vitamins and minerals. In fact, egg white powder has been referred to a complete protein source containing high amounts of all essential amino acids, which are as high as whey proteins.
During the process of manufacturing egg white powder, liquid egg yolk is removed and liquid egg white is pasteurised to remove traces of bacteria. After the pasteurisation process, egg white is then spray-dried into a powder that not only increases solubility but also extends the product shelf life.
Below is a table showing the protein quality rankings across a few food products that are known to consist of high protein content. Based on the data below, egg has the highest protein efficiency ratio and net protein utilization. What this means is that egg is an excellent protein source in terms of the ingestion of nitrogen from the protein consumption of eggs for growth and synthesis. In fact, egg also has a biological value of 100 second highest to whey proteins as well as high protein digestibility score, meaning it has high supply of the essential amino acids and that the amino acids are efficiently utilized in the body.
