Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Currently, lipid scientists are searching for alternatives or solutions to a concern widely discussed by health organizations around the world, namely, the demand to limit the amount of saturated fat intake by the population. The present work considers the development of a lipid system with zero trans fat and low contents of saturated fatty acids (low sat). Palm oil (PO) was used as zero trans fat basis and canola oil (CO) as a source of low sat lipids. The functional attributes of these mixtures were adjusted by the incorporation of a structuring agent (sorbitan monostearate-SMS) and a crystallization modifier (fully hydrogenated canola oil-FHCO). Blends of PO with CO were formulated and the effects of adding 6% of a mixture of FHCO and SMS (50: 50 w/w) to the samples were evaluated measuring the solid fat content by NMR, the thermal events by DSC and the polymorphism by XRD. Result for the oil blend (50: 50 PO: CO) indicated a reduction of 40.52% in the content of saturated fatty acids compared to the original sample (100: 0 PO: CO). The additives increased the consistency and the thermal resistance of the samples and proved to be effective in forming a homogeneous structural network, ensuring the continuity of the liquid oil inside the lipid matrix. Practical applications: This research on oleogels systems has demonstrated the great potential of structuring agents for a wide variety of applications. The oil-based fats development can be used to replace high saturated fats or hydrogenated oils in formulation of margarines, shortenings, spreads, and other specific applications.11711 17621771Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)FAPESP [2009/53006-0]
