- Abstract
This work aimed to enhance hemp seed oil encapsulation within a hemp seed protein-alginate complex by optimizing parameters in the solution-enhanced dispersion process, employing supercritical carbon dioxide (SEDS) without reliance on organic solvents or elevated temperatures. By response surface methodology (RSM), the microencapsulation efficacy (MEE), particle size (PS) and peroxide value (PV) was determined with respect to three parameters; temperature (°C), pressure (bar) and feed flow rate (mL/min). The optimum conditions were predicted at temperature (40 °C), pressure (150 bar) and feed flow rate (2 mL/min) to offer an MEE of 89.47%, PS of 7.81 μm and PV of 2.91 (meq/kg oil). In addition, the SEDS method was compared with spray- and freeze-drying for encapsulating hemp seed oil. The findings demonstrated SEDS' superiority, exhibiting exceptional attributes such as the highest MEE, smallest PS and the production of spherical, smooth microcapsules. This highlights its effectiveness in comparison to spray- and freeze-drying methods., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Chin Ping Tan reports financial support was provided by Malaysia Ministry of Higher Education.
