Milk protein isolate provides a total milk protein source that is derived from fresh milk. The non-chemical filtration process used to produce milk protein isolates (MPIs) allows proteins to remain in their native state, almost completely intact.

If you have been using caseinates or whey protein powder, you might consider making the switch to MPI. You will get the benefits of both whey protein and casein, without any off-flavors.

The Benefits of Whey Protein

Whey proteins are a form of milk proteins. Whey protein comprises approximately 20% of total proteins found in milk. Whey, the watery portion of milk, is typically produced as a byproduct of cheesemaking. It contains several important amino acids, the building blocks of the human body.

Research demonstrates many benefits of whey protein. It can aid in weight loss efforts and it can help lower cholesterol. It may help fight cancer and improve the immune response of children with asthma. Beverages supplemented with whey protein can help lower blood pressure and potentially reduce the risk of heart disease and stroke.

When used as a nutritional supplement, the protein is rapidly released and metabolized in the body. Some research has shown that supplementing with whey protein can help in the development of lean muscle mass in athletes. Many athletes and workout enthusiasts report positive results from consuming whey protein products before, during or immediately after a workout.

On its own, whey protein does not have a pleasant taste, consequently, when used as an ingredient in protein drinks, nutrition bars, etc., flavorings and sweeteners are typically included to offset the unpleasant flavor.

The Benefits of Casein

Casein accounts for 80% of the protein found in milk. It is a complete protein that contains critical amino acids the body does not produce on its own. It aids in digestion and research suggests it may help regulate gut health.

As a nutritional supplement ingredient, this protein is typically found in a concentrated form known as micellar casein. Casein aids in muscle recovery and acts to prevent the breakdown of muscle tissue.

Casein is metabolized much more slowly by the body compared to whey. It stimulates muscle repair and growth over the long term. The cell structure of casein causes it to remain in the stomach for an extended period, creating a feeling of satiety. Using casein in the morning, before bed or whenever you won’t have food readily available can help stave off hunger.

Is Milk Protein Isolate the Same as Whey or Casein?

No, milk protein isolate is essentially the same as whey and casein proteins combined.

Micellar casein and whey protein contain different nutrients and amino acids. MPI encompasses all the nutrients and amino acids contained in both whey protein and casein. In other words, MPI is a more complete dairy protein, much like real milk.

Is milk protein isolate the same as milk?

No, unlike real milk, MPI has had the majority of the lactose (milk sugar) and the fat removed. The bottom line is with MPI, you get all the nutritional benefits of milk without the lactose and fat.

Potential Uses of Milk Protein Isolate

Milk protein isolate is ideal for use in a variety of applications. One of the most popular applications is as a stabilizer and emulsifier in traditional and Greek yogurt. It is frequently used in ice cream and novelties, protein bars and protein drinks – both ready-to-mix (RTM) and ready-to-drink (RTD). Sports recovery drinks and bars are an ideal use for MPI.

Manufacturers use MPI in creamy soups, dips, sauces and dressings. It is also a highly valued ingredient in some infant formulas. This protein isolate powder can be used to improve the protein content of virtually any food, from cereal and snack bars to meats, cheeses and even whipped toppings.

Our IdaPro® MPI’s exceptional level of solubility sets it apart from other MPIs. It also offers a high level of heat stability and lower viscosity than many alternatives.

Is Milk Protein Isolate Better than Whey Protein?

Although whey protein is one of the most popular forms of protein supplementation, MPI offers several distinct advantages. Providing all the benefits of whey and micellar casein, MPI also lacks the unpleasant taste that characterizes whey.

When used as an ingredient in specialty nutrition products, sport nutrition products, weight loss products or virtually any other application, it provides multiple advantages that whey protein alone does not offer.
