Vegetable oils are frequently structured to enhance their organoleptic and mechanical properties. This is usually achieved by increasing the net amount of saturated and/or trans fatty acids in the oil. With the risk of coronary heart diseases associated with these fatty acids, the food industry is looking for better alternatives. In this context, the medium-chain dialkanoates of low-calorie sugars (sugar alcohol dioctanoates) are investigated as a healthy alternative structuring agent. Precursors of sugar amphiphiles, being FDA-approved GRAS materials, exhibited high cell viability at a concentration ~50 μg/mL. They readily formed nanoscale multilayered structures in an oil matrix to form a coherent network at low concentrations (1-3 wt %/v), which immobilized a wide range of oils (canola, soybean, and grapeseed oils). The structuring efficiency of sugar amphiphiles was computed in terms of mechanical, thermal, and structural properties and found to be a function of its type and concentration.
