Egg Protein Powder

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.

Health Benefits
  • Low in carbohydrates and fats - Due to the removal of egg yolk in the processing of egg white powder, the by-products contains virtually no carbohydrates and fats. For this reason, egg white powder is highly suitable for individuals seeking for weight loss option or following a strict diet.
  • No lactose - Since egg white powder is non-dairy, it contains no lactose, which makes it suitable for those who are lactose intolerant or have allergies.
  • Increase lean muscle mass Egg white powder has been found to contain high level of Arginine, which is a precursor of nitric oxide to stimulate growth hormone as well as insulin secretion with anabolic effects, therefore is effective in increasing lean muscle mass and energy.
  • Improve muscle recovery - Because egg white powder is known to be a complete protein containing all the essential amino acids, it has also been found that egg white powder contains as high amount of Branched Chain Amino Acids (BCAA) to whey proteins. Leucine in the BCAA promotes rapid muscle recovery from exercise via anabolic muscle building effects.
  • Moderate acting protein - Egg white powder has been found to be a moderate acting protein. What this means is egg white powder is absorbed in our body at a moderate speed which lies in between Casein (slow acting protein, taking up to 8 hours to be absorbed) and whey proteins (fast acting protein, taking up to an hour to be absorbed).
  • No traces of toxins and bacteria - as opposed to raw eggs Because egg white powder is pasteurised in the process, bacteria Salmonella that is present in raw egg white is removed, therefore eliminating symptoms of salmonella food poisoning such fever, nausea, dehydration, abdominal pain, cramping and headache which can lasts four to seven days.
