The Source: Where Does Whey Come From?

Whey is derived from milk as it is a liquid that consists of many of the same nutrients present in whole milk and is formed during cheese production. Whey contains amino acids, minerals, high-quality proteins, and bioactive compounds. Due to the bioavailability of these components, whey offers excellent support for muscle growth, repair and fitness, and overall healthy nutrition. The manufacturing process for whey starts with milk's passage through the cheese production process, separating it into curd and whey. The liquid portion is considered whey, as it can be processed further into whey protein.

Understanding the Milk-to-Whey Journey 

Whey starts out in whole milk. The curdling process of whole milk when preparing cheese causes the liquid portion (whey) to separate from the solid portion (cheese).

• A portion of the curd will ultimately be made into cheese
• A portion will ultimately be used to make whey protein
• Comprised of high levels of amino acids and electrolytes

(Note, this clear and lightweight liquids contain fast-digesting protein and, thus, comes highly recommended for both fitness and recovery).

How Cheese Production Creates Liquid Whey

Whey is made from cheese-making. When a milk curd forms after adding rennet to it, the proteins in the milk become curds and all of the liquid is drained off as whey.

• Whey form naturally during the process of cheese curd forming.
• Whey have all of the essential amino acids the body needs.
• Whey protein has very little fat but is very high in protein content.

Why Whey Is a Valuable Byproduct

Historically, whey was considered to be a low-value waste product of the cheese manufacturing process but today it is recognized as one of the most important nutritional by-products of dairy industries because of the very high-quality proteins it contains.

• The proteins in whey protein are very highly biologically active.
• The proteins in whey proteins help promote muscle recovery from a workout and improve immune function.
• The proteins in whey protein are very easily digested and quickly absorbed into the bloodstream.

(Whey protein’s light weight and high nutrient density make it ideal for a wide range of product applications, including Supplements, Sports Nutrition, and Growth Stimulating Products used in Medical Formulations).

Step-by-Step Process: How Whey Protein Is Made

To create whey protein, a series of specific actions are taken to create a high-quality powder of protein that has been completely processed through all stages so that it contains all of the nutrients and minimal amounts of fats and carbohydrates and contaminants. It is a scientific, pure, and precise method from start to finish that requires many methods of filtration (filtration methods), pasteurization, and drying.

Filtration Techniques (Microfiltration vs. Ultrafiltration)

Filtration is the first major step in converting whey from liquid form to a concentrated protein source. This process effectively separates fat, sugar (including lactose), and unwanted contaminants from the whey.

Microfiltration:

• The process uses large filter membranes
• The larger filter removes the larger particles, fats, and contaminants
• The larger filter retains many of the natural nutrients

Ultrafiltration:

• The process uses smaller filter membranes
• The smaller filter removes the smaller particles including lactose
• The smaller filter yields the highest quantity of protein and the purest whey available

Reasons:

The two filtering methods determine if the product will be whey concentrate or whey isolate.

Pasteurization for Safety and Freshness

Whey protein is pasteurized to make it safe from any bacterial contamination. This means that the bacteria that could cause food poisoning were killed during the pasteurization process.

• During the pasteurization process, the liquid whey was gently heated to the desired temperature.
• During the pasteurization process, all of the harmful microorganisms were eliminated.
• Pasteurization will allow the nutrients to be stable and protected in the whey.

Drying & Powdering: How Whey Becomes Shelf-Stable

After whey is filtered and pasteurized, it is still in liquid form. In order to convert the liquid into a powdered product, most manufacturers use spray drying to turn the whey into powder.

The spray drying method consists of:

• The liquid whey is sprayed into a heated area where the hot air quickly evaporates
• Very fine, soft protein powder falls into a container.

Why is this important?

• It allows the product to have a longer shelf life,
• It makes it easier to store, transport, and mix with water.
• It allows for a smooth, pleasant texture in mixes.

(The final product is whey protein powder. This powder is very light, very stable on a shelf, and ready to be flavored, packed, and shipped all over the world).

Differentiating the Types: Concentrate vs Isolate vs Hydrolysate

There are three kinds of whey protein with different characteristics that fit individual fitness and dietary needs. The types vary in terms of protein source purity, absorption speed and other nutritional properties, but all of them are great supplements for muscle recovery and growth. Among them, Whey Concentrate (WPC), Whey Isolate (WPI), and Hydrolyzed Whey Protein (WPH) all have their own health benefits that can benefit anyone looking to improve their body composition!

How Whey Concentrate Is Made (WPC)

Whey Concentrate is the least processed of the three. It’s created through the filtering process of liquid whey to remove some of the fat and lactose, while still keeping most of the minerals and vitamins.

• Contains between 70% and 80% of the total protein contents
• Contains a higher amount of healthy fats, carbohydrates and highly active nutritional components
• A great all-around protein supplement to use during training or for those just starting out in their fitness journey or looking to eat a balanced diet. (The creamy, smooth flavour makes it an easy addition to shakes, smoothies or other recipes as a daily protein source.)

How Whey Isolate Is Purified (WPI)

Whey Isolate has been filtered using additional filtering processes, such as micro or ultra-filtration, to remove virtually all of the remaining fats and lactose, resulting in an extremely pure protein source for lean muscle growth or performance goals.

How Hydrolyzed Whey Is Pre-Digested (WPH)

Hydrolyzed whey utilizes an advanced technique that breaks down the large protein molecules into smaller pieces (peptides) through enzymatic hydrolysis, creating a very easily digestible form of whey protein.

• Hydrolyzed whey protein is absorbed more quickly than other types.
• It also decreases muscle soreness and speeds up recovery time.
• Hydrolyzed whey protein is good for athletes, bodybuilders, and anyone who has trouble digesting regular whey protein.

(The amino acids in hydrolyzed whey get to your muscles nearly instantly after ingestion because they were pre-digested.)

Quality Control & Safety in Whey Protein Production

Whey Protein Goes Through a Series of Tests and Monitoring Process to Ensure That It Is Safe For The Consumer, Nutritious, And Effective For Use. All Steps Are Necessary For Maintaining The Purity Of Whey Protein, Keeping The Quality of Whey Protein, and Preventing The Contamination of Whey Protein During ProductionEach Batch Must Pass Rigorous Safety And Quality Inspection; All Whey Protein Produced Must Also Meet The Required Standards For Safety And Quality.
