Byproduct preservation

SoftAcid® is a very efficient additive for preservation of byproducts from the food and non-food industry.

The use of industrial byproducts is becoming more and more popular in the animal feed industry. These products can provide an excellent nutritional profile if preserved in a good way.


SoftAcid is an ideal product for this application, since it provides a fast, but controlled, pH reduction, favourable to the lactic acid bacteria naturally present in most food byproducts. Furthermore, SoftAcid has a strong bactericidal effect on pathogens, which helps preserve any type of food (bread, biscuits, candy, sweets, meat, etc.) and non-food (DDGS, okara etc) byproducts.

SoftAcid's prebiotic properties also help enhance beneficial bacteria, which leads to better stabilised products.

In protein rich byproducts (meat byproducts, fishmeal), SoftAcid can help reduce the oxidation (TVN, oleic acidity, biogenic amines) as shown in the table below.

Benefits

  • Efficient pH reduction and control
  • Reduced oxidation
  • Reduced corrosion rate 
  • Low volatility
  • More sustainable than pure acids
