ISSUE FOCUS 26 FEED & ADDITIVE MAGAZINE May 2023 factor but a sustainability issue. We must not lose scarce and valuable materials and nutrients. Overall shrinkage tends to be around 1%. For global feed production as a whole, 1% annual shrinkage is equivalent to 15 years of Croatian compound feed production! We help our industry to keep up sustainability efforts in terms of energy savings and shrinkage reduction by offering SurfAce. It’s a liquid preservative premixture with multiple economic and environmental benefits to the customer. It helps increase pellet output, improves conditioning, enhances the durability of the pelleted feed, reduces the formation of fines, and improves the overall quality of the final feed product. But most importantly, it optimizes feed production costs through energy savings and reduced labor input while also supporting the microbiological quality of the feed. In the food sector, we have seen vast improvements in non-thermal food processing over the past decade. Examples include ultrasonication, cold plasma technology, supercritical technology, irradiation, pulsed electric field, high hydrostatic pressure, pulsed ultraviolet technology, and ozone treatment. I’m sure some of these technologies will be applied to feed processing one day. Until then, we must keep up our high sustainability standards and make it more efficient by applying all available tools in our feed processing toolbox. References 1.

About Predrag Persak Predrag Persak is a veterinarian with 20+ years of experience as animal nutritionist in the compound feed industry. He has served as a Chairman of the Animal Nutrition Committee at FEFAC (European Association of Compound Feed Producers) between 2016-2020. He focuses on the interactions between feed formulation, feed ingredients, and feed processing, and their effect on animal performance. He is currently EW Nutrition’s Regional Technical Manager for North Europe, where he helps customers implement feed processing methods that enable higher nutritional value, as well as sustainable nutritional models that maintain the gut health of animals through processed feed materials.
