Abstract
|
|
|
|
This study was conducted to examine the proximate composition, alginic acid and mineral contents and the types of calcium and magnesium in the parts(frond, stipe, sporophyll) of sea mustards. Carbohydrates and the crude fat was the highest in sporophyll. The contents of alginic acid were 25.9~32.2%. Total alginic acid(32.2%) and insoluble alginic acid in water(27.7%) was e highest in sporophyll. Calcium and magnesium was the highest in frond. Phosphorous, potassium and sulfur was the highest in sporophyll. Iron, zinc and mangane was the highest in frond. Ca/P ratio in frond and stipe was about 1.7~1.8:1 levels. Calcium and magnesium soluble in sodium chloride was the highest in sea mustards. Calcium and magnesium soluble in water was the highest in frond. Calcium and magnesium soluble in hydrochloric acid was the highest in sporophyll.
