METHOD FOR PRODUCING FUCOIDAN EXTRACT, FUCOIDAN EXTRACT AND FOOD

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a fucoidan extract in which the characteristic color and smell of a seaweed are reduced, to obtain a fucoidan extract, and to provide a food to which the extract is added.;SOLUTION: A frozen whole sporophyll raw material is thawed and then washed with water to remove foreign matters from the surface of the raw material. The washed sporophyll raw material is soaked and boiled in 95°C hot water for 15 sec. The boiled sporophyll raw material is soaked and cooled in 10°C cold water for five minutes to produce the aqueous solution of the fucoidan extract. The aqueous solution of the fucoidan extract is mixed and deaerated with a sodium alginate solution prepared in a process for preparing the sodium alginate solution in a volume ratio of 30 % of the extract aqueous solution to 70 % of the sodium alginate solution by using a vacuum mixer. The product is pressed under a reduced atmospheric pressure and simultaneously extruded with a constant pressure into a bar-like product. The formed bar-like product is coagulated in an aqueous calcium chloride solution to produce the fucoidan extract product.;COPYRIGHT: (C)2005,JPO&NCIPI
