BACKGROUNDMany food products need to be reformulated to reduce the intake of saturated and trans fats which are considered unhealthy. In particular, the reformulation of filling creams (FC) is challenging as these fats cannot be directly replaced with liquid oil without affecting the final product properties. This research studied the formulation and characterization of FC for sandwich cookies using monoglycerides oleogels as fat material.RESULTS FC formulated with 260 g kg‐1 oleogel showed viscoelastic moduli values that did not differ significantly from those measured in a commercial filling cream used as reference (FC‐CSC). The oil binding capacity of FC decreased with the increase of oleogel content. The increase of the oleogel amount in the formulation produced a decrease in hardness but an increase in adhesiveness and cohesiveness. Hardness, adhesiveness, and cohesiveness ranged from 0.66 to 3.48 N, 0.44 to 0.86 N.s, and 0.07 to 0.29, respectively. When FC were used for assembling cookies into sandwiches, an oil loss of about 9 g kg‐1 FC after 21 days of storage was found in FC containing 220 and 260 g kg‐1 oleogel. The nutritional improvement due to the use of oleogels in FC led to a reduction in saturated fatty acids between 64.5% and 35.2% and from 1.0 to 0.0% trans fatty acids in comparison with FC‐CSC.CONCLUSIONFull fat replacement with monoglycerides oleogels in FC formulations allows the obtention of products with good quality and some similar characteristics to those obtained for FC‐CSC, with the added benefit of a healthier nutritional profile.
