Case Study

Lecithin for Enhancing Oil Stability in Peanut Butter

Ibrahim MMS, et al. Food Chemistry: X, 2025, 31, 103176.

This study investigated the application of sunflower and peanut lecithin powders as natural emulsifiers to reduce oil separation in peanut butter. Lecithin powders were incorporated at 1%, 1.5%, and 2% concentrations into freshly prepared peanut butter. GC-MS analysis quantified phospholipid content, revealing higher levels in sunflower lecithin (30.49%) than peanut lecithin (16.98%), along with increased linoleic (10.53%) and stearic acids (0.93%). Samples were stored under controlled conditions, and oil separation, peroxide value, and free fatty acids were periodically measured. Sensory evaluation assessed appearance, texture, and flavor. Peanut butter containing 2% sunflower lecithin exhibited the lowest oxidation markers and oil separation, demonstrating its superior functional efficacy as a stabilizing agent and its potential to extend product shelf life.

Lecithin for Enhancing Growth Performance, Lipid Metabolism, and Disease Resistance in Macrobrachium rosenbergii

Qiu Z, et al. Aquaculture, 2026, 611, 743016.

A 56-day feeding trial evaluated the effects of different lecithin sources-including soybean lecithin (SL), sunflower lecithin (SFL), egg yolk lecithin (EYL), and lysolecithin (LL)-on Macrobrachium rosenbergii. Experimental groups received diets supplemented with each lecithin type, while growth performance, feed conversion ratio, and lipid metabolism markers were monitored. Digestive enzyme activities and antioxidant parameters (SOD, CAT, MDA) were quantified, and hepatopancreas histology was analyzed to assess cellular integrity. Disease resistance was tested via bacterial challenge with Aeromonas hydrophila. Results demonstrated that LL and EYL notably enhanced growth, improved lipid utilization, strengthened antioxidant defenses, preserved hepatopancreas structure, and reduced mortality, highlighting lecithin's experimental application as a functional feed additive for aquaculture productivity and immune support.

Lecithin for Enhancing Stability of Pea Protein-Alginate Orange Oil Emulsions

Jain S, et al. Food Chemistry, 2025, 493, 45925.

This study evaluated lecithin as a secondary emulsifier to improve the stability of pea protein-alginate conjugate emulsions containing 20% v/v orange oil. Conjugates were synthesized at mass ratios of 2:1, 1:1, and 1:2 via transacylation and used at 1.0% w/v. Emulsions were prepared with 0.4-1.0% w/v soy lecithin and assessed at acidic pH (3.0 and 4.5) over 30 days at ambient temperature. Lecithin effectively reduced droplet size, enhanced co-adsorption with conjugates, and improved physical and oxidative stability under elevated ionic strength and thermal stress (90 °C, 10 min). Stability was maximized for conjugates with higher alginate content, demonstrating lecithin's practical application in developing acidified, flavor-oil-containing beverages.

Lecithin for the Development of PTFE Composite Coatings with Enhanced Anti-Scaling and Corrosion Resistance

Chen X, et al. Progress in Organic Coatings, 2025, 208, 109503.

In this study, lecithin was utilized to encapsulate ZrO₂/HEDP nanofillers, which were subsequently incorporated into a PTFE matrix to produce a protective composite coating on PE substrates. The filler was prepared by ultrasonically dispersing ZrO₂ in an ethanol-HEDP solution, vacuum drying, and then lecithin-assisted rotary evaporation in ethyl acetate. The composite coating was characterized via SEM, FTIR, TGA, XPS, QCM-D, and EIS, alongside adhesion testing. Results demonstrated that lecithin-encapsulated nanofillers improved adhesion to ISO 2409 grade 0, doubled polarization resistance, and reduced calcite adsorption by 38.2%, confirming the effective experimental application of lecithin in enhancing PTFE coating durability, hydrophobicity, and anti-scaling performance under alkaline conditions.
