Abstract
PURPOSE: To easily obtain a homogeneous and high-quality carrageenan in high yields, by subjecting red algae to an oxidation treatment and extracting, with heating, the treated algae at a neutral to weakly alkaline pH in a solution of an alkali or alkaline earth metal carbonate.
CONSTITUTION: Red algae are treated with a 0.01W0.1N acid solution (e.g., phosphoric acid or acetic acid) and then extracted, with heating, with a solution of an alkali or alkaline earth metal carbonate (e.g., Na2CO3 or CaCO3) at a pH of 7.0W10.5. By use of a carbonate, CO2 is liberated in the extraction liquor and forms a nonoxidizing atmosphere. Accordingly, air contamination can be prevented when the extraction liquor is stirred intensely and can prevent degradation of carrageenan. Homogeneous and high-quality carrageenan is obtained in high yields, by filtering the extracted liquor and drying the filtrate as such or adding a water-miscible organic solvent to the filtrate and filtering and drying the resulting precipitate, and grinding the dried product.
