Solution Overview

Problem

The food industry faces challenges in structuring edible oils without using high levels of saturated or trans-fatty acids, which are unhealthy, and existing methods require higher concentrations of crystalline triacylglycerols or waxes that are unstable and difficult to scale up, while there is a need for a food-grade oleogelator that is economical, efficient, and tolerant to processing conditions with potent thixotropic properties.

Innovation Solution

A composition comprising low molecular weight gelators of Formula (I) and vegetable oil, which forms gels at extremely low concentrations, exhibiting thixotropic properties and stable viscoelastic behavior, suitable for use in food, cosmetic, and pharmaceutical applications, allowing for the formation of water-in-oil emulsions with prolonged stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If crystalline triacylglycerols are used to structure oil, then the solid state and texture are improved, but the concentration required is high (up to 20 wt %) and the nutritional profile becomes unhealthy due to saturated and trans-fatty acids
