Acceptable Inclusion Levels for Selected Brown and Red Irish Seaweed Species in Pork Sausages.Foods. 2022 May 23; 11(10)F
Commercially available Irish edible brown (Himanthalia elongata-sea spaghetti (SS), Alaria esculenta-Irish wakame (IW)) and red (Palmaria palmata-dulse (PP), Porphyra umbilicalis-nori) seaweeds were incorporated into pork sausages at 1%, 2.5%, and 5%. Proximate composition, salt, water-holding (WHC), cook loss, instrumental colour analysis, texture profile analysis (TPA), and sensory analysis were examined. Protein (13.14-15.60%), moisture (52.81-55.71%), and fat (18.79-20.02%) contents of fresh pork sausages were not influenced (p > 0.05) by seaweed type or addition level. The ash content of pork sausages containing PP, SS, and IW at 2.5% and 5%, and nori at 5%, were higher (p < 0.05) than the control sample. In comparison to the control, sausages containing nori, SS, and IW at 5% displayed higher (p < 0.05) WHC. Cook loss was unaffected (p > 0.05) by the addition of seaweeds into sausage formulations, compared to the control and within each seaweed. The addition of seaweeds into sausages had an impact on the surface colour (L* a* b*) and texture profile analysis (TPA) at different inclusion levels. Overall, hedonic sensory acceptability decreased (p < 0.05) in cooked sausages containing PP at 2.5% and 5%, and SS and IW at 5%.
