Applications
Optimizes chocolate rheology for molding; stabilizes water-in-oil emulsions in spreads; aids in confectionery fat crystallization; in bakery shortenings for aeration; and in industrial fats for anti-bloom agents in export-oriented production lines.
Safety & Risks
EFSA-approved with ADI of 7.5 mg/kg body weight; potential for digestive intolerance in sensitive consumers. Low irritancy but avoid heated vapors; implement food-grade hygiene with aprons during hot processing to prevent slips.
Packaging
Poured into 180 kg food-approved mild steel drums with bung closures. Store in ambient temperature zones, labeled for traceability in supply chain audits.
