SoftAcid Aqua E is a very efficient preservative for the fish meal industry, where species like blue whiting, capeline and sandeel are raw materials for fish meal production.
SoftAcid Aqua E inhibits bacterial growth and delays the degradation of fish. The result is reduced total volatile nitrogen (TVN) and higher value products delivered to the fish-meal factory. Furthermore, the product will also take better care of your production equipment than other products on the market.
SoftAcid Aqua E is a combination of acetic acid and lignosulphonic acid, which controls the pH and reduces corrosion. Hence, SoftAcid Aqua E has all the well-known advantages from acetic acid, combined with reduced corrosion and safer handling.
- SoftAcid Aqua E
- Increased durability of the raw material (fish)
- Low corrosion rate

Preserving trials performance by Fiskeriforskning (The Norwegian Fish Research Institute) to evaluate the effect of SoftAcid Aqua E on fresh blue whiting. A competitor product (potassium diformate + formic acid) and a control sample with no added preservative were included for comparison.
The Competitor was able to preserve the quality for 2 extra days vs the Control, while SoftAcid Aqua E was able to preserve the quality for 4 additional days compared to the Control. SoftAcid Aqua E also showed an antioxidant effect on unsaturated fatty acids.
