The aim of this study is to develop stable formulations of ginger oleoresin using microencapsulation and emulsification technology. Different formulations of microencapsulated ginger oleoresin were formulated using spray drying technique. The advantage of encapsulation is that the formulations are water soluble unlike the oleoresin; which helps in reducing the use of solvents and promotes the use of natural product and widens its application range. The wall materials like polyvinylpyrrolidone (PVP) and maltodextrin (MD) showed the maximum encapsulation efficiency of 81.043%. The flow properties of microencapsulated powder were studied by analyzing the compressibility index and Hausner ratio for different combination of wall materials. The optimization of microemulsion was studied using pseudo-ternary phase diagram and the microemulsion with the maximum area was found in 3:1 (Surfactant: Co-Surfactant) ratio of Tween80- Propylene Glycol with caprylic-capric triglycerides as the oil phase and rest is the water phase. The ginger oleoresin diffusion study was carried out using Franz diffusion cell to study the active permeability, and stability of the formulations.

Abstract


The aim of this study is to develop stable formulations of ginger oleoresin using microencapsulation and emulsification technology. Different formulations of microencapsulated ginger oleoresin were formulated using spray drying technique. The advantage of encapsulation is that the formulations are water soluble unlike the oleoresin; which helps in reducing the use of solvents and promotes the use of natural product and widens its application range. The wall materials like polyvinylpyrrolidone (PVP) and maltodextrin (MD) showed the maximum encapsulation efficiency of 81.043%. The flow properties of microencapsulated powder were studied by analyzing the compressibility index and Hausner ratio for different combination of wall materials. The optimization of microemulsion was studied using pseudo-ternary phase diagram and the microemulsion with the maximum area was found in 3:1 (Surfactant: Co-Surfactant) ratio of Tween80- Propylene Glycol with caprylic-capric triglycerides as the oil phase and rest is the water phase. The ginger oleoresin diffusion study was carried out using Franz diffusion cell to study the active permeability, and stability of the formulations.
