Compressible extruded granules containing microencapsulated oil powders


Ying, Dan Yang and Ong, Yee Ling and Cheng, Li Jiang and Sanguansri, Luz and Shen, Zhiping and Augustin, Mary Ann (2016) Compressible extruded granules containing microencapsulated oil powders. Powder Technology, 291. pp. 276-283. ISSN 0032-5910; ESSN: 1873-328X


Gelatine-based dough formulations (47%, 60% or 70% w/w total solids) with embedded microencapsulated fish oil powders were extruded, dried and compressed to obtain tablets with 35% w/w oil. The effects of dough total solids and pre-conditioning temperature (20, 35 or 50 °C) prior to extrusion on the amount of oil leakage from the tablets were examined. Oil leakage from tablets was lowest when made from extrudates of dough with 47% w/w TS and pre-conditioned at 35 °C. Increasing dough total solids increased oil leakage. This suggests that adequate hydration of the matrix, necessary for functionalization of the protein, was essential for subsequent tableting performance. The ability to make directly compressible formulations with embedded microencapsulated oil powders broadens the application of spray-dried fish oil powders into the nutritional supplement markets.
