Modification of the solid phase lines of naturally occurring oils and fats is required to produce optimal hardstocks for fat continuous products like margarines, spreads and shortenings. Trans-free hardstocks are produced by combination of the trans-free modification techniques: full hydrogenation, interesterification, and fractionation together with the choice of the feedstock. The introduction of trans-free hardstocks in domestic margarines since 1995 has drastically reduced the daily trans intake by European consumers.
Key words:oil modification / trans fatty acids / full hydrogenation / interesterification / fractionation
