Preparation and Physicochemical Characterization of Hemp Seed Oil-Based Emulsions Stabilized with Different Emulsifier Systems
Öz
Industrial hemp is a valuable plant with high economic potential due to the versatile utilization of all its components. Hemp seed oil is also considered an economically important natural raw material. However, the high content of unsaturated fatty acids in hemp seed oil leads to low water solubility, chemical instability, and consequently poor bioavailability. Therefore, the development of hemp seed oil-based emulsion systems is of considerable importance. In this study, water-based emulsions containing hemp seed oil, olive oil, and black cumin seed oil were prepared at three different oil concentrations (5%, 10%, and 15%). Different emulsifiers and auxiliary components, including Span 80, Polysorbate 60, Polysorbate 80, mono- and diglycerides, and sucrose, were utilized in the emulsion formulations. For the characterization of the prepared emulsions, emulsion stability, creaming index, zeta potential, droplet size distribution, FTIR spectra, and color parameters were evaluated. The obtained results demonstrated that the oil type, oil concentration, and emulsifier type had significant effects on the physicochemical and rheological properties of the emulsions. The findings revealed that both the oil type and emulsifier type markedly influenced zeta potential and particle size. Systems containing Polysorbate 80 without sucrose exhibited smaller particle sizes and higher electrostatic stability. Hemp seed oil–olive oil combinations formed more homogeneous emulsion structures compared to the other systems. The emulsion activity index (EAI) values varied depending on the emulsifier type and oil phase composition, while Span 80–polysorbate systems provided higher emulsion activity. Furthermore, among the binary oil systems, hemp seed oil–olive oil emulsions exhibited higher and more stable EAI values compared to hemp seed oil–black cumin seed oil emulsions.
