Abstract
This invention provides alginate oligosaccharides comprising calcium alginate oligosaccharide, which is obtained by treating potassium alginate and/or sodium alginate with a polysaccharide-decomposing enzyme (alginate lyase) produced by a microorganism and substituting potassium ion or sodium ion in the potassium alginate oligosaccharide or sodium alginate oligosaccharide thus obtained with calcium ion, and potassium-enriched potassium alginate oligosaccharide, which is obtained by substituting sodium ion in said oligosaccharide with potassium ion, and a method for producing the same. The present invention further provides a food which contains the above-mentioned alginate oligosaccharide and exhibits an antihypertensive action.
