Have you ever ever thought of what protein powder is? Like, actually give it some thought? Clearly, it is “protein,” however what does that even imply? The place does it come from, and the way is protein powder made? These are just some of the questions this text will reply. This text is for you for those who’ve ever sat and questioned what you are mixing in your post-workout shake.
However let’s begin with the fundamentals.
What Is Protein?
Protein is one in all your three macronutrients, with the opposite two being fats and carbs. Of those three, protein holds a particular place in diet because it performs essentially the most important function in constructing muscle.
It does this by triggering muscle protein synthesis and optimizing your physique’s means to construct muscle. It additionally accommodates amino acids, that are the constructing blocks of muscle tissue and help muscle restore and restoration.
Principally, protein helps your muscle tissue develop.
What Is Protein Powder?
At the start, you want to perceive one factor: protein powder is “actual” meals.
There’s plenty of confusion about protein powder, with some even suggesting it is not “actual meals”—they declare it is simply “processed” meals and even that it is not wholesome for you. This false impression is probably going attributable to them not having learn this text, so they do not perceive how protein powder is made.
In fact, there’s loads of nuance on the place you draw the road between processed meals and unprocessed. Nevertheless, when you perceive what protein powder is and the way it’s made, you may possible be shocked at how “actual” it’s.
That stated, protein powder is extracted from an actual meals supply. It is then processed, filtered, and blended with different compounds, ensuing within the protein powder you already know and love.
This course of can fluctuate relying on the meals supply leading to many varieties of protein, comparable to milk, peas, and soy. The market has advanced a lot which you could purchase protein powder derived from steak and organs!
No matter the place the protein got here from, crucial factor to recollect is it comes from meals! Actual meals! Saying protein powder is not actual meals is akin to saying that an egg white omelet is not actual.
Now let’s get to the precise manufacturing course of…
How Protein Powder Is Made
Not like some would have you ever consider, protein powder just isn’t synthesized inside a lab like pretend meat.
As talked about above, it is derived from actual meals. As completely different protein powders come from actual meals, step one, getting the protein, will look completely different relying on the meals supply.
With that stated, we’ll take a better, extra detailed take a look at whey protein because it’s the most well-liked protein powder available on the market.
1. Milk Is Collected And Pasteurized.
Whey protein is derived from milk, and whereas it could possibly come from any mammal’s milk, cow milk is most frequently used. Nevertheless, many do not understand that casein protein additionally comes from milk. The truth is, solely 20% of the protein present in cow milk is whey protein, whereas the opposite 80% is casein.
Think about that human milk is 70% whey; you may see how low that’s.¹ Nevertheless, it is attention-grabbing to notice {that a} mom naturally offers her youngsters with a better proportion of whey protein.
Moooving on…
The very first thing that should occur is that the milk have to be collected after which pasteurized. Pasteurization is a purifying course of during which the milk is boiled at 70-80 ° C to kill any potential micro organism after which immediately cooled to 4° C.
As soon as the method is full, the milk is able to have its protein extracted.
2. The Protein Is Remoted From The Meals Supply
To separate the whey protein from the opposite compounds in milk, a substance often called rennet is put into the milk, which causes these two proteins to separate into two substances: a watery substance and a coagulated substance.
The coagulated substance is the casein protein. That is taken and despatched off to be processed as cheese however may be used to make casein protein powder.
The water substance accommodates whey protein. Nevertheless, it additionally accommodates fat and carbs (lactose).
Learn our submit on Casein vs Whey to learn how these two substances differ.
3. The Whey Protein Is Filtered
The liquid is then despatched via a collection of machines to filter out fat and carbs. This ends in a whey protein focus that’s normally round 80-85% protein.
This course of, and different filtration processes, might be repeated to create whey isolate. When whey isolate vs focus you may see the protein proportion dramatically will increase whereas the lactose content material is lowered. Some producers take this filtration course of a step additional to break the protein down into smaller peptides leading to hydrolyzed protein powder.
4. The Liquid Protein Is Dried And Flavored
As soon as the specified filtration happens, the purified liquid whey is then dried, both utilizing an enormous dryer machine or a course of often called spray drying. These processes warmth up and draw out the liquid, leading to a powder.
At this level, the protein powder is free from any coloring or flavors. As pure whey protein would not have the best style, it is then despatched off to produce other compounds added to it, comparable to flavoring and coloring. These different compounds are then blended evenly, ensuing within the remaining product.
This remaining powder kind is then packaged and despatched that can assist you placed on some mass.

How Different Protein Powders Are Made
As talked about above, the final concept is used to make most protein powders. The principle distinction is the method used to isolate the protein. This technique of isolating the protein can look very completely different relying on the meals supply.
We’ll briefly describe how these different protein powders are made.
Pea Protein
Yellow peas are harvested and cleaned to take away particles and impurities.
The cleaned peas are floor into a rough flour or powder.
The pea flour undergoes a technique of extracting protein from the peas by mixing the pea flour with water to kind a slurry.
The slurry is then centrifuged or filtered to separate the protein from the pea’s fiber and starch elements.
As soon as separated, the protein within the liquid extract is precipitated out. This may be achieved via numerous strategies, comparable to adjusting the pH or including enzymes or acids, which trigger the protein to coagulate and separate from the liquid.
The precipitated pea protein is then dried to kind a powder.

Rice Protein
Brown rice is collected after which undergoes a milling course of to take away the outer hull, leading to whole-grain brown rice.
The brown rice is handled with enzymes to interrupt down the carbohydrates and fibers, permitting the separation of the protein.
The combination is then filtered to separate the protein from the remaining solids (fiber, starch, and so forth.).
As soon as separated, the protein within the liquid extract is precipitated out. This may be achieved by adjusting the pH or including acids or different brokers that trigger the protein to coagulate and settle out of the answer.
The precipitated rice protein is then dried to take away moisture and kind a powder.
Egg Protein Powder
Egg whites are first separated from the yolks.
The egg whites are filtered to take away traces of yolks and different impurities. This step ensures that the protein powder will predominantly be egg white protein.
The filtered egg whites are pasteurized to make sure they’re free from dangerous micro organism and pathogens. Pasteurization entails heating the egg whites to a selected temperature after which quickly cooling them just like the milk.
The pasteurized egg whites are then dried right into a powder kind.
As soon as dried, the egg white protein powder undergoes testing for high quality and purity. This consists of checks for protein content material, absence of contaminants, and adherence to security requirements.

How A lot Protein Ought to You Eat?
When discussing protein as an entire, not simply protein powder, athletes ought to goal to devour round 1.6-2.2 grams of protein per kilogram of physique weight. For instance, for those who weigh 100kg, you need to goal to eat round 200 grams day by day.

Outro
As we specified by this text, making protein powder is pretty tame. We’re positive it’s kind of extra difficult than it sounds, nevertheless it’s not fabricated in a lab via chemical reactions. In the end, it is extracted from a meals supply, remoted, after which dried into powder. This protein powder is then blended with flavoring, and that is that.
