Preston Protein Products traces its roots to 1910, when a group of 57 farmers formed the Preston Creamery Association. More than a century of continuous dairy operation stands behind the ingredients we ship today — a depth of experience few dairy ingredient suppliers can match.
In 2020, Diversified Ingredients acquired the facility as a joint venture with Johnson Farms, combining a long dairy heritage with the sourcing, logistics, and quality infrastructure of a national ingredient supplier. The result is a dairy ingredient manufacturer built on tradition and backed by modern supply-chain support. Learn more about Preston Protein Products.

We spray dry liquid dairy proteins into a powdered state for use across a range of food-grade applications. Our processing spans three core capabilities — drying, condensing, and separating — so we can deliver dairy ingredients in the form your formulation requires.
Finished products are available in packaging from 50 lb bags up to 2,000 lb totes, sized to fit both pilot runs and full production. Custom product blends are available where a standard ingredient doesn’t fit the spec.
Our dried and condensed dairy ingredient portfolio includes:
Whether you need whole milk powder for a bakery application or a high-protein whey concentrate for a nutrition formula, our processing range covers the core dried dairy ingredients manufacturers formulate with.
Beyond single ingredients, we produce functional, food-grade dairy blends built to a customer specification. Drawing on our drying, condensing, and separating capabilities, we can combine dairy streams to hit the functional targets a formulation needs — protein level, solubility, heat treatment, and more.
For manufacturers who need more than a stock ingredient, custom blending gives you a dairy input engineered for your product. See our custom dairy blending capabilities for detail.
Our dried dairy ingredients are produced to food-grade standards and used across food manufacturing, pet food, and feed applications. Dairy powders contribute protein, functionality, palatability, and nutritional value to a wide range of formulations.
From human-food products to pet nutrition and feed rations, manufacturers rely on consistent, well-documented dairy ingredients to hit their formulation and label targets. We produce to that consistency batch after batch.
Quality is verified in-house. Preston Protein Products operates an on-site lab and performs in-house testing to ensure every product meets our customers’ quality standards before it ships. Testing at the source means issues are caught before product leaves the facility, not after it reaches your plant.
Our ingredients and facility carry meaningful certifications — USDA Organic, Kosher, Halal, and SQF — that matter to ingredient buyers and their own customers. See full detail on our quality standards, and for parent-company programs, Diversified Ingredients quality assurance.
