Whey Protein Hydrolysate

Proteins are macromolecules that facilitate proper growth and development of our body. Proteins help in building as well as repairing the cells and tissues of the human body. If our diet doesn't include proteins, our muscles will take much longer to heal from an injury. Proteins also act as catalysts for various metabolic processes and boost our immune system. Amino acids are the building blocks of proteins and hence facilitate their synthesis. While non-essential amino acids are synthesized by our body, the body's requirement for the essential amino acids can be met through dietary sources. This is why consuming foods rich in essential amino acids is important. Whey protein is a great source of essential as well as non essential amino acids and that's why it is increasingly being used in the form of protein powder or supplements. These supplements are generally sold in the form of whey protein isolate and whey protein concentrate. At times, whey protein may be hydrolyzed so as to make it more digestible. Such a form of whey protein is referred to as whey protein hydrolysate. In this article, we will try to find out more on different forms of whey proteins and the benefits of using whey protein supplements.

Forms of Whey Protein

As mentioned earlier, whey is a by-product that's obtained while making cheese. When cow's milk is curdled, the watery part that is left behind is separated and passed through fine filters. The watery part is referred to as whey. The globular proteins that are a part of whey, are extracted through the process of filtration. The proteins are then processed in an ion exchange tower. The final product, which is the whey protein powder is obtained only when the process of purification, concentration and dehydration of the isolated whey is complete. These days, many different processes such as micro-filtration, ultra-filtration or cross flow filtration are being used for extraction of whey protein from whey. The aim of these processes is to provide a better amino acid profile and minimize the denaturing of proteins while processing whey. If you go to the market for buying whey protein powder or supplements, you will come across forms of whey protein such as whey protein isolate, whey protein concentrate and whey protein hydrolysate.

Whey protein isolate and whey protein concentrate vary in the composition of protein and fat content. While whey isolate is a concentrated form with more than 90% protein, whey protein concentrate has a protein content that may lie anywhere between 29% to 89%. Fat and lactose content also differs in these two forms. Hydrolyzed whey protein is the form that is easier to digest. Since amino acid peptide bonds are fragmented into shorter chains of amino acids, the end-product is easier to digest. This process also lowers the risk of an allergic reaction. This is the reason why this form of whey protein is used in infant milk formula. However, the process of breaking down the amino acid peptide bonds do impart a bitter taste.

Uses of Whey Protein

Due to the complete amino acid profile of whey proteins, these can be of great use to those suffering from a protein deficiency. Since proteins are needed for repairing muscles and enhancing bone strength, it is very beneficial for those who wish to build muscle mass. This is the reason why whey protein supplements are used by body builders and athletes. Due to its digestible nature and great absorption rate, the partially hydrolyzed whey protein is easily absorbed by the body. Those who perform endurance training or energy-consuming workouts greatly benefit from the use of whey protein. It helps in healing the injured or tired muscles. Whey protein is also an immune booster. Due to the presence of an antioxidant called glutathione, it also helps in reversing damage caused by free radicals. If you are planning to use whey protein supplements, make sure that you buy the form with a low content of fat and lactose. A hydrolysed whey protein isolate is a good option for those who wish to lose weight or those who are lactose intolerant. If you find it unpalatable, you can look for a whey protein supplement that offers a mix of hydrolyzed whey protein with other forms of whey protein. Though the health benefits of whey protein seem to be numerous, having it in a high dosage, can lead to undesirable side effects such as kidney or liver damage. So, before you start taking these protein supplements, consult your doctor.

If you are using whey protein hydrolysate to build a muscular body, make sure that you take it as per the prescribed dosage. Though this form of whey protein is highly digestible, it is bitter and expensive as well. Before you buy one, make sure that you go through the reviews and purchase a whey protein powder by a reputed brand known for offering good quality protein supplements.
