Oleogelation for saturated fat replacement in vegan cheese

Area of Science:

• Food Science
• Materials Science
• Nutritional Science

Background:

• Vegan cheese often has high saturated fat content.
• Oleogelation offers a potential method to reduce saturated fats in food products.
• Understanding oleogel properties is key to developing healthier vegan cheese alternatives.

Purpose of the Study:

• To investigate oleogelation for reducing saturated fat in vegan cheese.
• To evaluate the impact of different oleogelators and oil compositions on oleogel and vegan cheese properties.
• To assess the tuneability of vegan cheese characteristics using oleogel-based formulations.

Main Methods:

• Formulation of oleogels using various oleogelators (phytosterols, monoglycerides, stearic acid, carnauba wax).
• Adjustment of oleogelator concentrations and oil phase compositions.
• Characterization of oleogel hardness, oxidative stability, and vegan cheese properties (hardness, adhesiveness, meltability).

Main Results:

• Phytosterol oleogels showed significantly higher hardness compared to monoglyceride, stearic acid, and carnauba wax oleogels at 20 wt%.
• Oleogels generally had lower oxidative stability than control oils; phytosterols exhibited a pro-oxidant effect.
• Oleogel-based vegan cheeses demonstrated tunable hardness and adhesiveness, superior meltability, and drastically reduced saturated fat content (from 28% to as low as 2%).

Conclusions:

• Oleogelation is an effective strategy for significantly reducing saturated fat in vegan cheese.
• The choice of oleogelator and formulation allows for precise control over vegan cheese texture and meltability.
• This approach offers a promising pathway to healthier, functional vegan cheese products.
