PURPOSE:To provide a humectant composition with a natural feeling and the same water activity reducing ability as that of sucrose or glycerol, by preparing a humectant composition containing a hydrolyzate of a fucoidan-like substance obtained from brown alga. CONSTITUTION:A brown alga or ground brown alga is blended with 0.01-0.5 N diluted hydrochloric acid, heated, extracted, neutralized with an alkali and concentrated under reduced pressure. Ethanol is added to the concentrated solution to precipitate a fucoidan-like substance. Then, the fucoidan-like substance is hydrolyzed with an acid, enzyme, etc. When the acid is used, it is not particularly limited, either inorganic acid or organic acid may be used and sulfuric acid or hydrochloric acid is preferable. The hydrolyzate can be directly used as a humectant composition or used after drying. |
