Prolactal GmbH (formerly Lactoprot Alpenländische Milchindustrie und Handels GmbH) produces and sells a large range of milk and dried whey products, as well as milk and whey derivatives, which are sold both as conventional and organic products. Prolactal's product range includes specialities for the chocolate, ice cream and baby food industries.

As a member of the Artax Group, Prolactal has access to the know-how of its international affiliated companies and benefits from synergy effects. As a result of the group’s strategic realignment, Prolactal now focuses more explicitly on the development, production and worldwide marketing of blends and special products with functional characteristics. To signalise this fact, and to permit a clear distinction from the single ingredient segment in the Artax Group, the company was renamed Prolactal (formerly Lactoprot) in May 2008. Single ingredients, such as casein or caseinate are sold by the affiliated company Lactoprot Deutschland GmbH, with Rovita GmbH taking over the "Savoury" line.

Prolactal sees itself as the worldwide partner of its customers, to whom it provides high-quality, innovative product solutions that are perfectly adapted to its customers' needs. Prolactal exports more than 75% of its products, and operates in the following international markets: 

-         Germany
-         Western and Northern Europe
-         Asia (Japan, China, Korea)
-         Eastern Europe

Prolactal places great emphasis on research and development: many new basic products are developed for customers on request or adapted to their requirements. It is Prolactal's declared aim to continue specialising and to further intensify and deepen its fruitful co-operation with members of the scientific community, researchers and the industry.
