Abstract:
The purpose of the present study was to prepare the solidified microcapsules and identify the effect of granulation and compression on the quality and stability of solidified spine date seed oil (SDSO). The fatty acid profile and the oxidative stabilities of the products were applied as indicators. The microencapsulation of SDSO–loaded granules were prepared using an electrostatic layer-by-layer deposition method and subsequently compressed as tablets. The study of granulation suggested that the impeller and chopper speed significantly affect retention efficiency of SDSO in granules (P < 0.05). However, the peroxide value was not affected by these parameters (P > 0.05). The overall study also suggested that the fatty acid composition was not changed significantly during the microencapsulation, granulation, and compressing process (P > 0.05). Moreover, the peroxide value of SDSO in the tablets (9.79 ± 0.62 mmol/kg) was lower than SDSO (47.57 ± 5.25 mmol/kg) and the microcapsules (23.16 ± 3.06 mmol/kg) (P < 0.05), after accelerated storage for 12 days, although the oxidative stability of the SDSO contained granules (84.23 ± 2.19 mmol/kg) was not satisfied in this study. The results of this work suggested that the microencapsulation of functional oils followed by the high shear granulation and tabletting process could be applied for oil products solidification due to the advantages of stability.
