Sensory and Nutritional Characteristics of Seasoned Laver Pyropia yezoensis with Concentrates of Octopus Octopus vulgaris Cooking Effluent

摘要

This study aimed to compare on sensory and nutritional characteristics between seasoned Laver Pyropia yezoensis with concentrates of octopus Octopus vulgaris cooking effluent (SL-COCE) and commercial seasoned laver (C-SL). Proximate composition of SL-COCE was significantly higher in moisture and ash, lower in lipid than those of C-SL. However, there was no differences in protein between seasoned lavers (P<0.05). The SL-COCE was stronger in sensory appearance, taste, flavor and texture than the C-SL.The SL-COCE was higher in mineral (Ca, P, K, Fe and Zn) than the C-SL. Total amino acid content of SL-COCE was slightly higher than that of C-SL. The major amino acids of SL-COCE were aspartic acid, glutamic acid and alanine. Mineral content based on the100 g of SL-COCE was 272.3 mg in calcium, 392.2 mg in phosphorus, 1,025.8 mg in potassium, 10.6 mg in iron, 4.4 mg in zinc, which was higher than C-SL. Total content of fatty acid per the 100 g of SL-COCE was 35,098 mg, which was lower than C-SL (39,679mg). The major fatty acids of SL-COCE were 16:0, 18:ln-9 and 18:2n-6.
