Our ProTain^TM range of feed additives that make a difference in stabilizing feed ingredients in grouped into two areas:

Application	Product range
Synthetic antioxidants	ProTainTM OT
Natural antioxidants	ProTainTM NA

The aim of the ProTain^TM product line is to prevent oxidation as early and quickly as possible in the propagation phase. Perstorp is a supplier of ProTain^TM antioxidants to the petfood and feed industries.

You can obtain detailed information on their properties, application and effectivity on animal performance from our application specialists or our website.

ProTain^TM OT
The ProTain^TM OT range includes antioxidants based on synthetic ingredients.

The composition of the ProTain^TM OT products is based on the following principles:

• Synergistic combinations of radical scavengers (BHA, BHT, propyl gallate, etc.) to remove the free radicals (R•) responsible for the propagation reactions
• Chelators (e.g. citric and phosphoric acid) to minimize the catalyzing effects of metal ions in the initiation phase
• Surfactants to help spread the antioxidants quickly throughout feed
• Nanometer-size particles to give the high surface to volume ratio needed to boost the effectiveness of antioxidation reactions

ProTain^TM NA
Through our ongoing research activities a natural antioxidant range, ProTain^TM NA has been developed. The ProTain^TM NA range includes antioxidants based on natural ingredients.

The composition of the ProTain^TM NA products is based on the following principles:

• Synergistic combinations of natural antioxidants like tocopherols and plant extracts
• Natural chelators to minimize the catalyzing effects of metal ions in the initiation phase

Natural antioxidants are commonly used in the food and petfood industry.

Chelators
Chelators, e.g. citric acid and phosphoric acid, react with metal ions and form stable complexes. Through this reaction the catalyzing effects of metal ions in the initiation phase are prevented and thus the oxidation time is extended.

Dispersion

Surfactants
The liquid ProTain^TM products contain surfactants to ensure that the antioxidants are perfectly dispersed in fats and oils.
