By-product preservation

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

The use of industrial by-products 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 by-products. 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.) by-products.

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

In protein rich by-products (meat by-products, 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
