Abstract
This research is aimed at developing a nutritious stable snack rich in omega-3
acid and to investigate the effect of extrusion on omega 3 fatty acids. A
formulation containing corn flour, rice flour and gram flour was extruded using a co-
rotating twin screw extruder. The formulations were optimized initially based on the
sensory analysis. Due to its high susceptibility to oxidation of fish oil rich in
unsaturated fatty acid, the omega 3 enrichment into the extruded product was planned
through following mode at the optimized levels to overcome the harsh conditions of
extrusion processing; by addition of fish oil (2%), fish oil emulsion (2%),
microencapsulated fish oil powder-commercial (1.5%) and laboratory prepared
(1.5%), fish mince fatty fish (5%), flax seed powder (10%), microencapsulated
powder with pepper and salt surface (1.5%).
