RESUMO
The objective of the current study was to encapsulate flaxseed oil extracted from finely grounded flaxseed powder and determined for its fatty acids content by GC/FID. Ionotropic gelation method was used to form beads containing 40% flaxseed oil with vitamin E being used as an antioxidant agent. The study employed calcium chloride solution as crosslinking agent with a combination of sodium alginate and salep. The effect of polymer concentrations and calcium chloride concentration on the morphology, entrapment efficiency and oil release was studied. The encapsulation efficiency reached 93.46 ± 0.064% using 0.6% of salep and 2% sodium alginate with 0.3M calcium chloride gelling solution. In SGF medium, the matrix released only about 28.56% of the entrapped flaxseed oil after 2 hours. The rest of the oil then released in the SIF medium, continuing for up to 5 h to release 99.32% of the oil.
