Embodiment Construction

[0017] (1) Anticoagulation and antioxidation treatment of duck blood: 2 g / L ascorbic acid was used as an antioxidant, and the addition amount was 0.05%-0.1% of the blood volume; and 4 g / L trisodium citrate was used as an anticoagulant, The added amount is 16.7% of the blood volume;

[0018] (2) Centrifugation: centrifuge at 4000r / min for 30min, the supernatant is plasma, and the centrifuged sediment is blood cells;

[0019] (3) Hemolysis and cleavage of blood cells: Part of the blood cells are hemolyzed by heating and cooling the precipitated blood cells obtained by centrifugation at -20°C and 90°C, and then homogenized at 120MPa dynamic ultra-high pressure micro jet Under-machine treatment once for cell destruction to obtain hemoglobin;

[0020] (4) Stage enzymatic hydrolysis control: divided into two stages, the first stage is at pH 8.5, temperature 55°C, using 0.5% alkaline protease for 2.5h; the second stage is at pH 7.0, reaction temperature 50°C , use 0.3% neutral prot...

Abstract

The invention provides a method for producing heme iron by using duck blood. The heme iron with physiological activity within a specific molecular weight range is produced from duck blood which is a byproduct of meat duck processing by using integration of an anti-coagulation and anti-oxidization technology, a cold-hot varying temperature alternating technology, a dynamic superhigh pressure technology, a stage enzymolysis technology, an enzymolysis supernate decoloring technology, a membrane fractionation technology, a spraying drying technology and other technologies. The heme iron has the protein content being not less than 80 percent, the heme content being not less than 15 percent, and the iron content being 2.0-2.5 percent. According to the method provided by the invention, the additional value of the heme iron is increased, the duck blood resources are completely and comprehensively utilized, no pollutant emission is caused in the production process, and the ecological benefits without environment pollution can be achieved.

Description

[0001] technical field [0002] The invention relates to a process for producing heme iron by using duck blood as a raw material, and belongs to the fields of agricultural by-product finishing technology and food nutrition. Background technique [0003] Livestock blood is a food with high nutritional value, known as "liquid meat", it is rich in protein and trace elements (such as iron), as well as appropriate amount of minerals, vitamins, hormones, enzymes and other physiological activities substance. Animal blood is divided into plasma and blood cells, wherein the protein content of plasma is about 25% of the total protein content of whole blood, and the protein content of blood cells is about 15%. According to data, the number of poultry slaughtered in my country exceeds 9 billion per year, and the annual stock and slaughter volume basically maintain a growth rate of 5-10%. Usually, a poultry is slaughtered, and about 0.1kg of blood can be collected. During the annual me...
