Novel oleogel formulation for low-saturation confectionery applications
Chonnam National University presents a novel oleogel formulation utilizing pre-treated monoglycerides and canola oil to create a stable, low-saturation fat alternative for confectionery. This formulation aims to replicate the melting behavior of traditional fats while reducing saturated fat content.
Overview
Chonnam National University introduces an innovative oleogel formulation designed for the confectionery industry. This solution aims to replicate the desirable melting behavior of traditional confectionery fats while significantly reducing saturated fat content. By leveraging canola oil, native or pre-treated monoglycerides, and lecithin, this formulation promises enhanced stability and gelation texture, making it an ideal alternative for healthier confectionery products.
Technical specifications
The research focuses on two hypotheses: First, pre-treatment of commercially available monoglycerides (MGs) with trace amounts of catalysts can promote early hydrogen bonding, resulting in a more stable crystalline network and reduced oil separation. Second, oleogel systems with sharp melting behavior near body temperature can be achieved by specific ratios of canola oil, MGs, and lecithin, combined with controlled cooling methods. Preliminary experiments have shown promising results, with oleogel systems exhibiting main melting peaks around 30-38°C.
Key features:
- Use of pre-treated MGs and canola oil for reduced saturated fat content
- Enhanced crystalline structure and gelation stability
- Suitable for blending with structuring fats to achieve desired confectionery textures
Technology readiness level
The technology is currently at TRL 4, indicating that the oleogel formulation has been validated in a laboratory setting. Future validation will involve optimizing formulations through Response Surface Methodology (RSM) to ensure the oleogels meet desired rheological properties and are comparable to structuring fats used in commercial applications.
