EDIBLE FIBER SEPARATED AND PURIFIED FROM SHELL OF MARINE PRODUCT AND METHOD FOR SEPARATING AND PURIFYING THE SAME AND PRODUCTION OF FUNCTIONAL FOOD TO WHICH THE SAME IS ADDED

摘要

PROBLEM TO BE SOLVED: To provide a method for producing edible fibers from the shells of a marine product including Ascidian Halocynthia roretzi, and to provide a functional food containing the edible fibers produced by the method. SOLUTION: This method for producing edible fibers comprises repeating a step for extracting the shells of a marine product with a mixture solution of an oxidizing agent, an acid and water and a step for washing the extracted marine product shells and then immersing the washed shells in a basic solution. Thereby, the method for producing the edible fibers and the edible fibers separated from the shells can be used for purposes such as the viscosity reinforcement, water-retaining capacity improvement and physiological function addition of foods or processed products, and so on.
