Making Whey Protein

The Process of Making Whey Protein

Whey is the liquid part of milk that is separated during the process of making cheese. Whey protein is a mixture of proteins that have been isolated from whey.

Due to whey protein’s sulphur amino acids, lysine, and tryptophan, it is high in nutrition. And the high protein content makes whey protein ideal for use as a supplement.

Gym goers, professional athletes, and others often use whey protein powder. It is commonly added to shakes, protein bars, and meal replacements.

But how is whey protein actually created? Let’s take a look at the -making process.

Different Types of It

There are several varieties of it is available.

Ones of the highest quality include it’s concentrate, hydrolyzed one, and


There can be variations in the whey protein-making process too.

For instance, grass fed whey isolate has one of the highest protein-by-weight ratios, at 88%, but it also differs from other whey protein supplements because it comes from cows that are naturally fed. It is also free of artificial sweeteners, gluten, preservatives, and food dyes.

But regardless of the cows’ diet and later additions to supplements, the process of making it’s powder remains the same.

Step One: Transporting Cows’ Milk

First off, milk is required to make whey protein. Cows’ milk is shipped from dairy farms by tanker trucks to processing plants.

Step Two: Obtaining and Pasteurizing Liquid Whey

During at the cheesemaking process the processing plant, enzymes are added to separate the curd. The remaining liquid whey is then pasteurized.  the cheesemaking process

Step Three: Concentrating and Isolating Whey Protein

Next, the whey is sent to be concentrated and isolated. Two main methods are employed to achieve that. They are membrane filtration and ion exchange.

Membrane Filtration

This cold temperature separation process uses porous membranes. They help to eliminate bacteria while maintaining the important carbohydrates and minerals in the whey.

Ion Exchange

This process isolates specific protein components. It accomplishes that by sending raw whey through a column that collects the proteins and then separates them accordingly. The rest is washed away and can be used in other products. The great thing about ion exchange is it enables the selection of the functional and nutritional proteins contained in whey. That includes bioactive proteins such as lactoferrin and immunoglobulins.

Step Four: Spray-drying it into Powder

The final product is spray-dried into powder form.

Generally, depending on the method used, the final product will contain between 80% and 90% protein.

Once it has become a powder, it is ready to be shipped to manufacturers and suppliers of products.

Who should use It?

These supplements are mostly used for increasing strength and muscle mass. So, they are popular among athletes, bodybuilders, and fitness models, but they are often used by just anyone who is looking to improve their performance at the gym.

If you want to increase your muscle and strength, you should consider using whey protein supplements as part of your diet and workout routine.

The Benefits of It

While it is most commonly used for building muscle and strength, it could provide various other benefits.

Some studies show whey protein can lower blood pressure and blood sugar as well as reduce symptoms of depression and stress.

And while more research is needed, many studies have shown whey protein can reduce symptoms of hepatitis, improve immune function in people with HIV, increase bone mineral density, and even protect aginst cancer.
