Novel squid ink melanin chelate iron preparation method and application of method

Abstract

The invention relates to a novel squid ink melanin chelate iron preparation method and the application of the method in preparing anemia and iron deficiency anemia adjuvant therapy health food, functional food or medicines. The method is characterized by the following steps: melanin is separated from the squid ink firstly; the squid ink melanin is added into a buffer solution containing ferrous ions after vacuum freeze drying; the buffer solution is stirred for 8 to 24 hours under the temperature of 4 DEG C to 25 DEG C with the pH value regulated to 5 to 6; 3000-5000*g centrifugal collection for precipitation is carried out under the room temperature; then the precipitate is repeatedly washed by distilled water, and 3000-5000*g centrifugal collection for precipitation and vacuum freeze drying are conducted. The squid ink melanin chelate iron compound prepared through adopting the method utilizes rich and available raw materials and has extremely high melanin content. The method provided by the invention has the advantages of simple procedures, easiness in control, less equipment investment, no environmental pollution, high product yield, etc., and is suitable for industrialized production.

Description

technical field [0001] The invention relates to a preparation method of a novel squid ink melanin chelated iron and its application in the preparation of health food, functional food or medicine for auxiliary treatment of anemia. Background technique [0002] According to the 2002 Nutrition Survey of Chinese Residents, the average prevalence of anemia in Chinese residents is 15.2%; the prevalence of anemia in infants under 2 years old, the elderly over 60 years old, and women of childbearing age are 24.2%, 21.5% and 20.6% respectively. 30% of pregnant women are anemic, and it is even higher in the third trimester. Anemia can generally be divided into two categories: nutritional anemia caused by lack of iron or vitamin B12 and non-nutritive anemia caused by hematopoietic system dysfunction. Among them, nutritional anemia is mainly iron-deficiency anemia. There are many types of iron agents used for iron supplementation, commonly used are ferrous sulfate, ferrous fumarate, fe...

Problems solved by technology

However, due to the defects in the method at present, when the pH is greater than 4, iron ions are likely to form insoluble ferric hydroxide precipitates, which are difficult to control during the production process and cannot be industrialized.
