METHOD OF BROWN ALGAE GEL PRODUCTION FOR DIETARY AND PROPHYLACTIC FEEDING Russian patent published in 2008 - IPC A23L1/30 A23L1/532 A23L1/337 A61K36/03 

FIELD: food industry.

SUBSTANCE: method of brown algae gel production provides for cutting raw material and washing with sea water. Then it is washed in fresh water at the temperature 25-35°С for 20-50 minutes for even swelling not less than 30%. After that the algae is demineralized by 0.5% acid solution: acetic, citric or hydrochloric, рН=2.0, with the weight ratio of the algae and solution - 1:1.5 within 1-2 hours. The algae is washed in fresh water for 10 minutes and is soaked in fresh water at the temperature 20-35°С for 30-50 minutes and change the water 1-2 times. Let the water flow down for 10-20 minutes. The algae is cut and boiled in fresh water at the temperature 75-85°С with the algae and water ratio 1:1. Then add sodium bicarbonate till рН=7.0-8.0, which is controlled while boiling for 6-10 hours at the temperature 70-80°С and mix with agitator, rotation speed is 15-25 revolutions per minute. Cool till 35-45°С and homogenize within 30 minutes. Introduce citric acid solution - 0.1% and calcium salt solution- 0.2%. Mix for 10 minutes, heat till 75°С and transform into shape suitable for storage.

EFFECT: increases storage life, increased biological accessibility and iodine digestibility, prolonged action.
