    This study aimed to investigate the effect of the addition of organogels in low-fat and high-fat margarines during storage. Margarine formulations were made using water: oil ratios of 65:35 and 40:60 (w/w), and a lipid phase composed of organogel made with soybean oil, candelilla wax, fully hydrogenated palm oil, and mononoacylglycerols. The thermal stability, particle size, consistency, peroxide index, oil exudation, and microstructure of the margarines were evaluated for six months of storage. All margarines showed thermal stability at 35 °C, with no physical destabilization during the period studied. Both low-fat and high-fat margarines presented similar particle size distribution, with d3.3 around units of 5 μm. The peroxide index of the margarines ranged from 1.27 to 5.97 meq O2/Kg after six months of storage. High-fat margarines showed greater hardness and lower spreadability. The amount of water added to the formulations affected the stability, particle size, and texture of the margarines. It was possible to produce margarines with different fat contents and greater health appeal. The margarines with 60% and 35% fat exhibited 12.00 and 8.03% SFA; 32.63 and 18.20% PUFA; and 14.37 and 8.20% MUFA, respectively. Copyright © 2020 Elsevier Ltd. All rights reserved.
