Title: Texturizing composition and use thereof
Inventor: WESTER INGMAR
IPC: A23L33/20
Filed: 1997-11-03
Abstract: Fatty acid esters, such as the unsaturated fatty acid esters of sterols and/or stanols, are used as a replacement for a substantial portion or all of the undesirable saturated and trans-unsaturated fats used as structure giving hardstocks in edible foods such as margarines, mayonnaise, cooking oils, cheeses, butter and shortening. Because of the similarity in the crystallinity and physical properties of the esters to those of the undesirable hardstock fats, the substitution or replacement contributes favorably to the flavor, texture and other sensory properties of the foods.
