Sorbitan Ester Oleogels for Low-Saturated Fat Shortening Production

Vahid Hakimzadeh of Islamic Azad University Quchan conducted research on the structuring effect of sorbitan mono-stearate (SMS) and sorbitan tri-stearate (STS) in oleogels. The study measured physicochemical and rheological properties, including saturated fatty acid content, slip melting point, solid fat content, peroxide value, and free fatty acids, across different additive concentrations. Results indicated SMS-based structured fats exhibited greater consistency than STS-based ones, suggesting applications in products like soft tub margarine and bakery shortening.

Use Cases

• Modeling the relationship between sorbitan ester concentration and saturated fatty acid content based on the described experimental results.
• Analyzing the rheological properties (G', G'', G*, tan δ) of structured oils for texture prediction.
• Comparing the performance of SMS-based versus STS-based oleogels for specific fat-based product applications mentioned in the description.

Strengths

• The research includes specific measurements for key fat properties like saturated fatty acid (SFA), slip melting point, and solid fat content.
• Experimental design tested three distinct additive concentrations (3, 6, and 9 wt%).
• Rheological analysis provided quantitative data, reporting an increase in G' and G'' to 105 Pa.
