Select nutrient comparison of imitation shellfish with real shellfish
1988
Harris, C.H. | Johnson, J.M.
Select nutrients of three real shellfish, three imitation surimi based shellfish, and two imitation soy based shellfish were measured by gas chromatography, high pressure liquid chromatography and AOAC methods. The lipid was extracted, methylated and analyzed on a wide bore capillary column with temperature programming to separate the fatty acid methyl esters. Carbohydrates were analyzed isocratically by high performance liquid chromatography on a polar column. Sodium and potassium were analyzed by atomic absorption spectrophotometry. AOAC methods were used to determine percent moisture, protein, and fat. Analysis of variance for the select nutrients showed significant differences among the imitation and real shellfish products (P less than 0.05) for sodium, potassium, carbohydrate, moisture, fat and protein content. Significant differences were also present in the fatty acid methyl ester analysis. The data suggested that the imitation shellfish products differed significantly in nutrient content from the corresponding real shellfish.
