Perstorp unveils ProSid Pellet Pro moisture management product for feed mills

Perstorp presents ProSid™ Pellet Pro, a moisture management product for feed mills that combines glycerol esters of propionic acid, surfactants and glycerol. Company trials show moisture losses of up to 3% mitigated, recovering up to 3,000 tons of feed a year for a 100,000-ton mill, throughput gains of up to 18%, and energy savings of up to €1.10 per ton. Trial data also show up to 28% more water retention than untreated feed, with lower water activity supporting microbial control.

Key facts

Market context

Propionic acid and its esters are widely used as preservatives in animal feed, where they inhibit mold and bacterial growth and extend shelf life, particularly in humid climates and during long transport. Glycerol esters of propionic acid are a related form that releases the acid more gradually and is often blended with surfactants to improve how feed absorbs and holds water during conditioning and pelleting. Demand for these additives is driven mainly by livestock and poultry producers, compound feed manufacturers and pellet producers, all of which want higher throughput, lower energy use and fewer losses from spoilage. Products in this segment compete on performance per ton of feed, so moves toward esterified propionic acid blends can shift purchasing away from conventional surfactant and free-acid moisture treatments. Buyers and investors typically watch such shifts for signs of changing specialty additive volumes and pricing across feed milling and preservation.
