Lyotropic liquid crystals (LLCs) made of monoacylglycerols (MAGs) are rich in potential for food and pharmaceutical applications but the understandings of these materials are quite limited. This study, therefore, precisely demonstrated the formation of some LLCs based on the combination of two palm oil-based MAGs (distilled and non-distilled) with water and a triblock copolymer (Pluronic F127). X-ray diffraction results showed that the main lyotropic mesophase obtained from palm oil-based MAGs was lamellar phase (L α ) while dynamic light scattering results revealed that these LLC particles had a size range from 0.5 to 4 μm (after 5 min homogenization at 12,000 rpm). LLC dispersions made of both palm oil-based MAGs/water mixtures were shear-thinning fluids and the sample owning a higher concentration of MAGs had a higher yield stress as well as a higher storage modulus.
