Filtering and drying liquid whey to make powdered whey protein

Whey protein is a natural, high-quality protein found in cow’s milk. Containing all 9 essential amino acids our body needs, such as leucine or lysine, whey protein is considered a complete protein. Add a starter culture to the milk and leave it to ferment until solid curds and liquid whey form. Now you can separate the whey (watery part of the milk) from the curds by draining it from the vat.

The whey protein goes through a microfiltration process where ceramic microfilters remove fats and carbohydrates and leave liquid whey protein as a result. A hot and cold air dryer removes the moisture turns the liquid whey protein into powdered whey protein. Flavorings can be added and blend in with a mixer for uniform distribution.

How to pack whey protein powder?

Whey protein powder packaging is available in flexible plastic bags, hard plastic bottles, and glass bottles. The packaging or containers are properly sanitized before being filled with whey protein. A powder filling machine is used to fill containers for precision and minimum waste. Then, it is weighed to make sure the net content is the same as in the label. After filling and weighing the product, it is sealed to avoid product aeration or contamination from exposure.
