Abstract

The invention discloses agaro-oligosaccharide iron and a preparation method thereof. The agaro-oligosaccharide iron is prepared by using Gracilaria agar as a raw material through steps of refining, acid degradation, high-pressure pulse electric field-assisted chelation, membrane separation, freeze-drying and pulverization. The refining step increases the neutral sugar content significantly, and after acid degradation, the chelation of agaro-oligosaccharide and iron ions can be promoted under the catalysis of a high-voltage pulsed electric field. The method has advanced and reasonable technology and high production efficiency; the prepared agaro-oligosaccharide iron product has high iron content, has good oxidation resistance to enhance cell viability, and promotes the iron absorption by body, and has high bioavailability.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a preparation method of agar oligosaccharide iron. Background technique [0002] Iron is one of the essential trace elements for the human body. It is an essential component of hemoglobin and plays an important role in the transport of oxygen in the human body, the synthesis of deoxyribonucleic acid, and energy metabolism. Iron deficiency can lead to iron deficiency anemia or dysfunction. Studies have shown that 30% of the world's population suffers from iron deficiency, 46% of children aged 5-14 and 48% of pregnant women suffer from iron deficiency anemia. At present, the prevention and treatment of iron deficiency anemia is mainly achieved through the intake of iron supplements. Common iron supplements include ferrous sulfate, ferrous chloride, ferrous gluconate, etc. Although these iron supplements have high iron content, their stability is poor, and they are prone to produce ...
