How to Use Membrane Filtration Systems to Concentrate Whey Protein

Can membrane filtration systems revolutionize whey protein production?

Yes, its been done fore over 35 years.

Can they convert waste streams into high-value products?

Yes, it depends on what you want to remove.

Can they reduce certain production losses?

Depends on what are your definition of production losses, product, time, energy uses?

Contact any membrane supplier? it all depends on what your want to concentrate.

Its all in the process, ultrafiltration or reverse osmosis, can remove lactose from milk for people that is lactose intolerant. When you do that, membrane size would be 10,000 kDa (Daltons). Also MWCO (Molecular Weight Cut-Off).

When this occurs, not only do you remove the sugars (lactose) you also remove vital minerals. then what needs to be done is run it ther a second U,ltrafiltration unit to separate the lactose from the minerals.

The you reconstitute the minerals back into the milk.

Here's some information about membrane sizes;//

"Dalton is used to measure the molecular weight cut-off (MWCO) of ultrafiltration (UF) membranes, which defines the largest molecule that can pass through the membrane. UF membranes typically have a Dalton range of about 1,000 to 500,000, which allows for the separation of macromolecules like proteins, bacteria, and suspended solids from smaller molecules and solvents. A membrane with a 10,000 Dalton MWCO, for example, would retain molecules larger than 10,000 Daltons while allowing smaller ones to pass through.

• What Dalton measures: A Dalton is a unit of mass, equivalent to one atomic mass unit. In the context of UF membranes, it specifies the molecular weight of the largest molecules that can be retained by the membrane.
• UF membrane MWCO range: The typical range for UF membranes is between 1,000 and 500,000 Daltons (1 kDa to 500 kDa).
• Separation principle: UF membranes work by separating substances based on their molecular size. When pressure is applied, the solvent and smaller solutes pass through as permeate, while larger solutes are held back and concentrated as retentate.
• Application examples: The specific MWCO is chosen for different applications, such as:
• A 10,000 Dalton UF membrane can be used for enzyme concentration.
• A 5,000 or 10,000 Dalton membrane is often used in the dairy industry for whey and milk concentration.
• A 100,000 Dalton membrane is suitable for applications like water softening and pre-treatment for reverse osmosis (RO) membranes. "

Now there's more to this, it has to due with + or - ions or nuetral ions within the product and the membranes.

I tried to edit this, but when I posted, my edit was flagged as spam.

What I wanted to add, is correct some typos, bold the questions and add this bit of info...

using kDa to size the membranes is more accurate that specifying MWCO.
