| Abstract: |
| In this study, the production of fish oil nanocapsules using basil and gum seed coat with barberry extract and alpha-tocopherol by spray drying method was investigated. Initially, 4 types of fish oil picking emulsions in water with different stabilizers are as follows: 1- Basil-Zein gum, 2- Basil-Zein gum containing alpha-tocopherol, 3- Basil gum containing barberry-Zein extract and 4- Basil gum-containing Barberry-zein extract containing alpha-tocopherol was prepared. Following the research, the prepared emulsions were dried by nano-spray dryer and turned into powder. Particle size analysis of different emulsions showed that the particle size was reduced below 100 nm by ultrasound. Viscosity results for all samples showed pseudoplastic behavior. It was also observed in the frequency test all emulsions had elastic behavior at low frequency and viscous behavior at high frequency. Light microscope images showed spherical particles of different sizes. The redistribution index for the powder related to basil-saddle gum coating was the ability to recover to the primary emulsion and for the other powders it indicated the inability to recover to the primary emulsion. The results of spherical particle morphology with dense structures showed a smooth surface without cracks and in different sizes. X-ray diffraction analysis showed the crystalline nature of all powders and also the highest peak intensity was related to basil-saddle gum powder containing alpha-tocopherol and basil gum containing barberry-saddle extract containing alpha-tocopherol. Evaluation of oxidative stability of powders showed that the combined addition of alpha-tocopherol and barberry extract to the coating provided the most stability. |
