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

Laboratory trials
Laboratory trials conducted with questpharma in spain. different acid formulations were tested on salmonella choleraesuis and fusarium verticiloides. clear benefits with softacid were observed.

All you need to know about bacterial inhibition
Although microorganisms are very small in size, too small to be seen by the eye, they cause substantial economic losses each year for both the food and feed industry. microbial growth can be controlled either by prevention or inhibition – using an antimicrobial agent.
