Natural Waxes as Gelators in Edible Structured Oil Systems: A Review

Area of Science:

• Food Science
• Material Science

Background:

• Trans and saturated fats pose health risks, necessitating healthier alternatives in food products.
• Oleogels and bigels are structured oil systems with potential to replace unhealthy fats.
• Natural waxes offer a promising gelling agent for creating these structured systems.

Purpose of the Study:

• To review the use of natural waxes in formulating oleogels and bigels.
• To analyze the interactions, properties, and processing of wax-based structured oil systems.
• To explore the application of these systems in diverse food products.

Main Methods:

• Literature review on natural wax utilization in oleogels and bigels.
• Analysis of physicochemical properties and structural characteristics.
• Evaluation of processing parameter impacts and oxidative stability.

Main Results:

• Natural waxes effectively form oleogels and bigels, impacting their texture and stability.
• Processing parameters significantly influence the microstructure and properties of these systems.
• Wax-based oleogels and bigels show promise in improving the nutritional profile of food products.

Conclusions:

• Natural waxes are viable ingredients for creating healthier structured oil systems.
• Understanding formulation and processing is key to optimizing oleogel and bigel functionality.
• These systems offer significant potential for fat replacement in spreads, dairy, and meat products.
