FIELD: food industry.
SUBSTANCE: invention relates to brown sea algae processing technology. The method envisages milled raw materials soaking in water at a temperature of 35-40°C during 12 hours and washing. The milled raw material is subjected to acid treatment with acetic acid, to washing with water and to alkaline hydrolysis. Alkaline hydrolysis is performed at a temperature of 80-85°C during 2 hours in a water extract produced after soaking. The produced mass is homogenised and calcium gluconate is added. Then one performs neutralisation with a food acid, pasteurisation, sublimation drying and milling to produce a dry algae powder. The food product includes dry algae powder produced according to the proposed method and plant fruits processing products or a polysaccharide derivatives source.
EFFECT: invention ensures maximum preservation of valuable nutritional substances.
