A new method for utilization of unwashed mince (UM) mixture of low-cost marine fish (LMF) in cooked sausage is described. Textural qualities of heat-induced gels of six different mince blends from the individual unwashed minces of five LMF viz. red jewfish sea catfish horse mackerel jeweled shad and skipjack tuna were investigated. Blend B3 having greater contribution from low-fat white-fleshed red jewfish and sea catfish obtained best-textured gel and sausage in terms of instrumental gel strength and sensory parameters (p0.05). In order to improve the textural and sensory qualities of the sausage prepared from B3 suitable types and levels of ingredients and cooking methods were evaluated. Gels prepared with modified starch and soy protein isolate had distinctly (p0.5) improved gel strength and cook loss values. Sausage prepared with autoclave cooking at 115C for 15 min. obtained best texture and good mouth feel compared to conventional cooking (90C for 20 “ 60 min.) broiling (for 20 -60 min.) two-step heating (incubation at 50C for 1 hr and cooking at 90C for 30 min.) and dip-frying in oil (for 10- 30 min). Instrumental gel strength (p0.05) and sensory chewiness/rubberiness (p0.05) were lower in sausage prepared from B3 when compared to imported fish sausage. Instrumental gel strength sensory attributes and cook loss of the sausage prepared from B3 by different cooking methods were higher in the order of autoclave cooking frying two-step heating boiling broiling. Peroxide and thiobarbuturic acid values and aerobic plate count of the sausages after 7 days at 4C were almost identical in all cooking process (p 0.05) but distinctly lower (p0.05) than that of commercial fish sausage. Results of the study suggested that good quality stable fish sausage could be prepared from UM blends of LMF.

Abstract

A new method for utilization of unwashed mince (UM) mixture of low-cost marine fish (LMF) in cooked sausage is described. Textural qualities of heat-induced gels of six different mince blends from the individual unwashed minces of five LMF viz. red jewfish sea catfish horse mackerel jeweled shad and skipjack tuna were investigated. Blend B3 having greater contribution from low-fat white-fleshed red jewfish and sea catfish obtained best-textured gel and sausage in terms of instrumental gel strength and sensory parameters (p0.05). In order to improve the textural and sensory qualities of the sausage prepared from B3 suitable types and levels of ingredients and cooking methods were evaluated. Gels prepared with modified starch and soy protein isolate had distinctly (p0.5) improved gel strength and cook loss values. Sausage prepared with autoclave cooking at 115C for 15 min. obtained best texture and good mouth feel compared to conventional cooking (90C for 20 “ 60 min.) broiling (for 20 -60 min.) two-step heating (incubation at 50C for 1 hr and cooking at 90C for 30 min.) and dip-frying in oil (for 10- 30 min). Instrumental gel strength (p0.05) and sensory chewiness/rubberiness (p0.05) were lower in sausage prepared from B3 when compared to imported fish sausage. Instrumental gel strength sensory attributes and cook loss of the sausage prepared from B3 by different cooking methods were higher in the order of autoclave cooking frying two-step heating boiling broiling. Peroxide and thiobarbuturic acid values and aerobic plate count of the sausages after 7 days at 4C were almost identical in all cooking process (p 0.05) but distinctly lower (p0.05) than that of commercial fish sausage. Results of the study suggested that good quality stable fish sausage could be prepared from UM blends of LMF.
