Effect on instrumental texture, expressible moisture and oxidative rancidity when oleogel was employed as fat replacer in cooked sausages

Consumption of foods with saturated fats has been contributed to overweight in Mexican population. Saturated fat was replaced in 50 and 100% in cooked sausages to determinate differences in texture profile analysis ad shear tests with Warner-Bratzler blade and Meullenet-Owens razor blade. In same manner, expressible moisture and oxidative rancidity were studied. Saturated fat replacement by oleogel resulted in a softer but more cohesive texture. In shear tests, fat replacement resulted in the gradually decrease of the studied parameters, related to a less hard and easy to chew texture. Oleogel as fat replacer improved water retention, probably by the celluloses in oleogel, and decreased lipids oxidative rancidity by the unsaturated lipids present in oleogel vegetable oil. Results demonstrate that fat replacement with oleogel improved textural and nutritional properties of cooked sausages
