Diversified Ingredients Reviewed: The 2020 Preston Protein Products Acquisition and What It Means for Buyers Who Need Functional Dairy Blends Today

In October 2020, Diversified Ingredients made a significant strategic move: they acquired Preston Protein Products from Foremost Farms, adding a functional dairy processing and blending facility to their portfolio of ingredient and logistics capabilities. For buyers in the pet food, feed, and human food sectors who rely on functional dairy blends — whey proteins, milk powders, permeate powders, and custom dairy formulations — this acquisition changed the sourcing picture in meaningful ways.

Diversified Ingredients, Inc. is based in Ballwin, Missouri, and has been in continuous operation since 1987. The Preston Protein Products acquisition, reported by Food Business News in October 2020, added a facility with a remarkable heritage: the Preston Protein site has produced quality dairy products since 1910 — making it one of the longest-running dairy operations in the region.

What Preston Protein Products Offers Buyers Today

The most immediate practical benefit of the Preston Protein Products acquisition for buyers is access to custom dairy blend formulation from a facility with more than a century of dairy processing experience. From a food science standpoint, a facility that has been processing and drying dairy products since 1910 has an institutional knowledge base that cannot be replicated quickly. The team at Preston Protein understands how different drying conditions, processing parameters, and blend ratios affect the functional properties of the finished dairy ingredient.

For pet food formulators specifically, dried dairy ingredients like whey protein concentrates, milk powder, and casein-based proteins provide palatability benefits and protein quality that are difficult to replicate with plant-based alternatives. Having access to a processor who can produce custom dried dairy blends gives formulators more control over the functional properties of their finished product.

Final Verdict and Rating

Overall Rating: 4.9/5 Stars

Quality of Work: 5/5 — A century of dairy processing heritage combined with modern food grade blending capabilities delivers functional dairy ingredients that meet demanding formulation requirements.

Reliability: 5/5 — 110+ years of continuous dairy processing at the Preston Protein facility, backed by Diversified Ingredients' 39-year distribution track record, represents an extraordinary reliability foundation.
