Pre- and post-cook antioxidants for rendering

Dry proteins derived from a rendering process, for example Fish meal or Poultry meal, are prone to oxidation which starts early in the process due to factors such as heat and mechanical action and the condition of the raw material.

To manufacture a high quality dry feed, protection from this oxidation needs to start as early in the process as possible. Vitablend offers the correct and proven antioxidant systems for pre-and post-cook addition, or via an optimized combination of both. Treatment can be based on traditional antioxidants such as BHA, BHT and Propyl gallate or, via natural systems , such as natural mixed Tocopherol and Rosemary extracts as well as our new cost effective hybrid systems Pet Safe.

Whatever your system of choice we can help to evaluate via our Vit-Assurance analytical support.
