LOW-DOSE MINERAL FLOW CONDITIONING IN VITAMIN-MINERAL PREMIXES FOR RUMINANT NUTRITION Scientific rationale, evidence hierarchy, regulatory considerations and a validation framework for ACARISINTM

Vitamin-mineral premixes are technologically demanding particulate systems whose performance depends on far more than nominal nutrient composition. Flowability, resistance to caking, segregation behaviour, moisture distribution, dosing reproducibility and the chemical stability of labile micronutrients all determine whether a premix can deliver its formulated value during manufacture and storage. These challenges are especially relevant when vitamins coexist with hygroscopic ingredients and reactive trace-mineral salts. ACARISINTM is a proprietary dry mineral preparation incorporating a silica-based surface-conditioning component within a processed mineral matrix under an specific mineral architecture known as SGFT* (Single Grain Fusion Technology). The quantitative formulation and manufacturing parameters and processes are proprietary and are not disclosed in this review. The application assessed here is low-dose incorporation, up to 3 g/kg of vitamin-mineral premix, before subsequent dilution into ruminant compound feed or dry-in application. This paper critically examines the scientific rationale for that technological use. Powder-science literature shows that appropriately dispersed silica materials can disrupt cohesive interparticle forces, alter contact geometry, improve flow and reduce caking tendency, with efficacy governed by host-particle properties, moisture, mixing conditions and concentration. In parallel, feed-premix research demonstrates that vitamin stability is strongly influenced by storage time, temperature, humidity, choline chloride and the source, particle size and reactivity of trace minerals. The evidence therefore supports a scientifically credible role for ACARISINTM as a physical flow-conditioning and anti-caking system in dry vitamin- mineral premixes, but does not justify describing the product as a direct vitamin stabiliser without product-specific analytical data. Improved physical behaviour may create a more favourable microenvironment for vitamin retention; that secondary benefit remains a testable hypothesis. A tiered validation programme combining powder rheology, caking resistance, moisture and water-activity measurements, blend homogeneity, segregation testing and longitudinal vitamin assays is proposed. This evidence hierarchy provides a robust basis for technical positioning while preserving proprietary formulation confidentiality, what it ́s mandatory under legal conditions and applicable law.
