METHOD OF MANUFACTURING BIOLOGICALLY ACTIVE PRODUCTS FROM BROWN ALGAE Russian patent published in 2009 - IPC A23L1/30 A23L1/337 

FIELD: food products manufacturing technique.

SUBSTANCE: method implies processing brown algae, washing and drying. Afterwards the algae are washed in fresh water under 25-35°C for 20-50 minutes with intermittent stirring to ensure even swelling for not less than 30%. Next stage involves demineralization by 0.1-2% solution of at least one food acid with pH=2.0 with weight relation of the algae and the solution being equal to 1:1.5 and following curing for 0.5-1.0 hours under 10-50°C. Then the solution in which demineralisation took place is filtered, desalinated and separated. The algae are washed in fresh water for 10-12 minutes and steeped in drinking water under 20-35°C for 30-50 minutes. Water is dripped down for 10-20 minutes. The washed algae are crushed and put into a cooking vessel, added are also at least part of the above filtered and desalinated food acid solution used for the demineralisation, drinking water 75-85°C hot and at least one food alkali until pH 7-12 is reached. Cooking during 0.5-18 hours under 40-100°C, cooling down to 35-45°C and homogenisation for 30 minutes follow. Neutralisation by the solutions of citric acid in the amount of 0.1% and edible calcium salt in the amount of 0.2% of the algae weight is carried out. Heating up to 75°C and converting into the form suitable for storage with the 50-99% water content and at least 30% of polysaccharides on dry solid basis follow.

EFFECT: reducing losses of biologically active substances and manufacturing product in the form of stable complex with increased content of biologically active and easy digestible substances.
