Interesterification Capacity Investment Accelerates Across the Industry
Major oils and fats producers have committed significant capital to interesterification capacity over the past several years, converting fat modification processes away from partial hydrogenation toward enzymatic and chemical interesterification that avoids trans-fat formation entirely. This shift follows the World Health Organization's global elimination target and subsequent national regulatory action across dozens of countries. AAK, Bunge, and Cargill have each expanded interesterification lines at existing facilities rather than building entirely new plants, reflecting the technology's maturity. The remaining capacity gap is concentrated in emerging markets where regulation has arrived more recently.
