Steps of Protein Manufacturing- Picture Courtesy: Wicked Protein

Before your protein supplement is packed into protective packaging, it goes through several multi-step processes, each responsible for transforming whole plant-based or dairy-based food materials into dry powders for your shakes.

Let’s discuss the complete order of these steps in the following section:

Starting Material Selection and Preparation

Selection	Typically, your protein manufacturing on a large scale begins with the selection and preparation of source material. Depending upon your consumer demand, you either select milk-based proteins, plant-based proteins, or both.
Pretreatment	Now that you’ve picked out your desired protein source, you’ll process these proteins. For instance, for dairy-based proteins, you’ll collect milk, assess its quality, pasteurize it, and then separate it into casein or whey. In the case of plant-based proteins, you’ll harvest plants, clean them, and grind them into fine powder.

Extraction

Believe it or not, this step has a central place in protein manufacturing. Why? Because at this stage, your favored protein is isolated from other nutrients, for instance, carbohydrates, fats, fibers, and other micronutrients. However, it is worth noting that based on the source material, this step is carried out in different ways:

Filtration	When you’re creating whey protein powder, you’ve to use specialized membranes having diverse pore sizes to pass liquid whey. With the help of these filtration procedures, you can easily extract protein molecules from small compounds, such as water, lactose, or minerals.
Chromatography	In this method, various columns, especially ion exchange chromatography are used to separate out protein molecules from the solution. At this stage, resins in the column having ionic compounds bind with proteins, while other materials in the solution wash away with liquid. After that, you use buffers to elute bound proteins.
Wet Fractionation	This method is mostly employed for isolating plant-based proteins. At the start, the ground plant powder is mixed with water. Then mechanical methods, like centrifugation to fraction proteins and other compounds. You can also use different buffers and enzymes to extract soluble proteins from insoluble fibers and starch.

Purification
