Oleogel technology for enhancing oil melting points

Overview

Oleogel technology provides a sustainable and efficient solution for increasing the melting point of oils without altering their fatty acid profiles. This innovative approach utilizes oleogelation to create a three-dimensional gel network that entraps liquid oil. The process employs a variety of oleogelators, including plant-based waxes and phospholipids, which are generally recognized as safe (GRAS) by the USFDA. This technology is particularly valuable due to its high availability, excellent structuring properties, and cost efficiency, making it ideal for food and industrial applications.

Technical specifications

Oleogelation involves three main types of structuring mechanisms based on the building blocks of oleogelators:

• Crystalline particles: Utilizes monoglyceric stearate and waxes to form a gel network through self-assembly.
• Self-assembly fibers: Employs phospholipids to create fibrillar structures that gel liquid oil.
• Polymeric strands: Uses materials like ethyl cellulose, forming a supramolecular network via hydrogen bonding. Recently, egg yolk phospholipids have been used as odorant precursors, demonstrating the method's adaptability and functionality in dispersing phospholipids evenly in oil.

Technology readiness level

The technology is currently at TRL 4, indicating that it has been validated in a laboratory environment. Future validation plans include refining oleogelator selection, optimizing the oleogelation process parameters such as dosage and cooling rate, and assessing the stability of the oleogels through various analytical methods.
