What Is Whey Permeate? Whey Permeate 101

OVERVIEW

What Is Whey Permeate?

Whey permeate is a dairy ingredient created during the whey protein concentration process. As proteins are removed and concentrated, the remaining dairy solids — primarily lactose and minerals — are dried into whey permeate powder.

Known for its naturally balanced dairy flavor and cost-effective functionality, whey permeate is widely used in bakery, confectionery, dairy, beverage, prepared food, and animal food applications.

HOW IT'S MADE

VersiLac^® Production Process

Cheese Making

Milk Preparation

Pasteurized milk is standardized to control fat

Coagulation

Enzymes turn milk into curds and whey

Curd Processing

Curds form cheese, and leftover liquid is whey

Ultrafiltration (UF)

Filtration

Whey is filtered through membranes to separate smaller components

Permeate

The filtered liquid, rich in lactose and minerals, becomes permeate

Concentration & Drying

Concentration

Water is evaporated, increasing the solid content

Drying

The concentrated permeate is spray dried into a powder for easy storage and transport

FORMULATION INSIGHT

Why Mineral Content Matters

Mineral content can impact how whey permeate performs in your formulation. Low mineral whey permeates can help reduce salty notes in applications where flavor is critical.
