ARTICLE FEED & ADDITIVE MAGAZINE November 2025 105 Very low secondary compounds of oxidation like hexanal molecules resulting from linoleic acid oxidation and degradation were recovered as shown by Table 2. Above 10 ppm Hexanal Pet food manufacturer considers the fat oxidized: CONCLUSION The Verafyt LR 35 Liquid formulation, with its specific balance of active molecules and carrier enhancement effects, can protect sensitive poultry crude raw materials during the stressful heating dry rendering processes phases. It provides more than 3 months of poultry PAP stability when only the crude raw materials are treated and more than 12 months of PAP stability when combined with PAP treatment at the end of the process. This is the first time in dry rendering history we have achieved similar efficacy than synthetic antioxidants molecules at so low cost in use. The pet food industry can fully and safely stabilize their end pet food products with natural origin molecules now. References 1Krabbe, E. “Quality of raw materials” AMVEA Peru, 2013 2E.N.
