Oleogel Systems for Chocolate Production: A Systematic Review

Area of Science:

• Food Science and Technology
• Materials Science
• Nutritional Science

Background:

• Chocolate's popularity is linked to its sensory appeal, but high saturated fat content from cocoa butter (CB) raises health concerns.
• Consumer demand for healthier food options is increasing, driving innovation in food formulations.
• Reducing saturated fats in foods without compromising quality is a significant challenge in the food industry.

Purpose of the Study:

• To review advancements in oleogel systems as a strategy for reducing saturated fats in chocolate.
• To explore the potential of oleogels in improving chocolate's stability and sensory attributes.
• To investigate pectin-rich agro-industrial by-products as sustainable structuring agents for oleogels.

Main Methods:

• Literature review of oleogel systems and their application in chocolate.
• Analysis of oleogel properties in mimicking saturated fat functionalities.
• Exploration of sustainable sourcing for oleogel components.

Main Results:

• Oleogels can effectively mimic the physical and sensory properties of cocoa butter.
• Incorporating oleogels into chocolate formulations shows promise for reducing saturated fat content.
• Pectin-rich agro-industrial by-products present a viable and sustainable option for oleogel production.

Conclusions:

• Oleogels represent a promising approach to developing healthier chocolate products with reduced saturated fats.
• Further research is needed on the physicochemical properties of oleogels and oleogel-based chocolates.
• Sustainable sourcing of oleogel components can enhance the environmental profile of reduced-fat chocolate.
