Hydrocolloid-based oleogelation for lipid-based healthy foods
Innovative oleogels using commodity oils and plant-based structuring agents offer a sustainable, scalable solution for replacing saturated fats in bakery products. By optimizing interactions between proteins, polysaccharides, and oleogelators, these oleogels enhance texture and stability.
Overview
This research focuses on developing oleogels structured from commodity oils such as olive, canola, and flaxseed. By utilizing plant proteins and polysaccharides, this solution aims to replace saturated fats in food products, particularly in the bakery sector. The innovation lies in controlling the texture and stability of these oleogels through pH modulation and the use of Hofmeister ions, coupled with covalent bonding techniques. This method not only enhances sensory attributes but also improves oxidative stability, providing a healthier alternative to traditional fats.
Technical specifications
Key features:
- Use of commodity oils structured with plant protein and polysaccharide networks.
- Modulation of non-covalent interactions via pH and Hofmeister ions.
- Incorporation of low-molecular-weight oleogelators such as lecithin for enhanced organoleptic properties.
- Production through emulsion templating, foam templating, and hybrid gel systems.
Applications:
- Bakery products like compound chocolate and pastries.
- Potential for broader food applications where fat replacement is desired.
Technology readiness level
Currently at TRL 3, this technology is in the early stages of development and has undergone initial proof-of-concept validations. Further optimization and prototyping are planned to advance the technology toward commercial readiness.
