Emulsion filled gel with oleogels as oil fraction to enhance nutritional properties of baked products (muffins).

Abstract

In baked products, such as muffins, the fat reduction to decrease the caloric content is important without detrimental effects on product quality. Among the fat replacers, emulsion-filled gels imply lower fat depending on the oil fraction. The objective of this work was to replace soybean oil in muffins formulation with two different emulsion-filled gels, containing candelilla wax oleogel or ethylcellulose oleogel as oil fraction, to enhance nutritional quality. Colour, texture, crumb quality, moisture, fat, and protein were analysed. Emulsion-filled gels samples resulted in a darker colour, and a more hard and resilient texture, as a reflection of lower cells number developed in crumbs during baking; but there was a lower fat and an increase in protein content. Emulsion-filled gels with candelilla wax as oil fraction are a alternative to decrease caloric content without compromising the energetic values of the foods.
