OptiPhos Plus

Beat the Heat

Following the positive opinion received from the European Food Safety Authority (EFSA), we are delighted to confirm that OptiPhos® Plus has now received full European registration for use in all poultry and pigs species at a minimum dose of 250 FTU/kg. [Official Journal of the European Union entry].

OptiPhos® Plus is a next-generation phytase product, specifically developed to retain all the favourable characteristics of OptiPhos® with improved thermostability.


In pelleted feeds, the thermostability of phytases has always been important. Loss of enzyme activity during the pelleting process can lead to phosphorus deficiency and low animal performance levels.

Now feed mills can add this intrinsically heat stable phytase directly into the feed, as it is able to withstand the temperature and pressure conditions of the pelleting process.

  • OptiPhos® Plus G (granular) can be used up to 85°C
  • OptiPhos® Plus CT (coated) can be used up to 95°C

These recommendations are supported by pelleting trials carried out at more than ten different trial locations in the US and EU since 2017.

PPS screening for improved performance

We use the PPS concept to screen and develop new phytases; it stands for pH, pepsin resistance and speed.

The phytase must be able to perform in an acid environment (pH 2 – 4) as found in the gizzard/stomach, it must be resistant to pepsin, and it must be able to work at a high speed to quickly degrade phytate found in the feed.

Moreover, OptiPhos® Plus also has shown to exhibit a higher affinity for phytate, further improving matrix values compared to the already excellent performance levels of OptiPhos®.

Feed cost savings while reducing environmental impact

Supplementing the diet with a phytase enzyme helps the animal unlock the phosphorus that would otherwise be bound in the form of phytate. The phytase enzyme cleaves off phosphorus molecules from the phytate, making them available to the animal for absorption. This reduces the need to include inorganic phosphorus sources in the diet, equating to a significant saving on the cost of the feed. This reduction in the inclusion of inorganic phosphorous sources also reduces the excretion of phosphorous in the local environment.

Now registered in the EU

Following the positive opinion on OptiPhos® Plus from EFSA, this revolutionary next-generation product has now also received full EU registration for use in all poultry and pig species at a minimum dose rate of 250 FTU/kg.
