Glycerol, when esterified to propionic acid, helps to reduce water activity which create an environment that will inhibit microbial growth. It is well known for its hydrophilic properties and can hold up to 1000 times its own weight in water. It works like a magnet, drawing water that was sprayed into the mixer into the feed particles as bound moisture helping SmartMoisture support up to 3% moisture addition.
SmartMoisture also confers the emulsifying and humectant properties of glycerol. Our patented glycerol ester technology, further improves surface tension reduction which allows for greater penetration of moisture into the feed materials reducing evaporation and free water.
