Description
The contents of general nutrients in dried“naruto wakame” (Undaria pinnatifida) were investigated and the results obtained were as follows ; Crude ash: 16-44%, Protein: 7.5-24.2%, Lipid: 1.4-6.8%, Carbohydrate: 37-49%. The contents of minerals in dried“naruto wakame”were spread over the following ranges: Fe: 6.3-30mg%, Ca: 647-1, 176mg%, I: 95-157ppm, P: 237-425mg%, Mg: 163-312mg%, although they varied with the size and part of the sample. Of the total I in dried“naruto wakame”, 28-31% was extracted in the first step with warm distilled water, 11-12% in the second step with ethanol, none by treatment with benzene, and 57-59% of the total remained in the residue. The extraction rates of minerals from“naruto wakame”during immersion treatment with artificial digestion fluid for 30-120min at 37°C were approximately as follows; Crude ash: 85±10%, Fe: 45±29%, Ca: 68+21%, I: 61±6%, P: 67±19%, Mg: 77±22%. Fe, I and P were extracted more easily by digestion fluid than by water at the same pH, but Ca and Mg were extracted to the same extent.
