Actus Nutrition (Actus), a leading North American speciality ingredient manufacturer and portfolio company of Butterfly Equity (Butterfly), and Darigold, Inc., one of the nation’s leading dairy cooperatives, finalised a strategic partnership to expand the production of milk proteins and other speciality food ingredients. The partnership between Actus and Darigold is built on two components involving facilities in Jerome, ID, and Sunnyside, WA.

In Jerome, ID, Actus will take ownership of the facility and continue to manufacture non-fat dry milk. In addition, Actus intends to invest in the facility to expand its manufacturing capabilities to produce high-value milk protein products with continued supply from members of the Northwest Dairy Association co-op. This will be the second facility operated by Actus in Jerome.

In Sunnyside, WA, Darigold will produce and supply sweet whey powder, along with high-value whey products, exclusively for Actus Nutrition under a long-term commercial agreement. Whey protein markets have undergone tremendous growth in recent years due to strong consumer demand and product innovation.

“We continue to see strong global demand for high-quality dairy proteins, and this partnership accelerates our ability to meet that demand,” said David Lenzmeier, Chief Executive Officer of Actus Nutrition. “The reliability of Darigold’s manufacturing operations and the quality of its member-owners’ milk make Darigold an excellent partner as we position ourselves to grow with our customers. Together, we are creating a more connected and efficient supply chain that supports innovation and delivers greater value to customers and farmer-owners alike.”

Actus produces a wide range of protein and speciality ingredients for major food and beverage brands. In addition to being the largest manufacturer of whey and milk proteins in North America, Actus also produces PRObev clear whey protein, CasPRO U.S.-made casein and caseinate, in addition to speciality ingredients such as lactoferrin, alpha-lactalbumin, and milk fat globule membrane (MFGM).

“Our partnership with Actus Nutrition allows Darigold to maintain focus on our core business of processing our members’ milk and serving our customers here in the Pacific Northwest and around the world, while participating in the growing market for speciality protein ingredients,” said Amy Humphreys, Chief Executive Officer of Darigold. “This partnership brings specialised expertise that complements our strong capabilities and will deliver long-term value for our member-owners.”
