Centrifugal extraction machine extract vitamin B2 application in the chemical industry
Vitamin B2 (
Chemical formula: C17H20N4O6)
Also called riboflavin, slightly soluble in water, heating in neutral or acidic solution is stable.
For yellow enzymes in the body part of the prosthetic group (
Yellow enzymes play a role of hydrogen in the biological oxidation reduction)
, when the lack of, will affect the body's biological oxidation, make the metabolic disorder.
its lesions characterized by inflammation of the mouth, eye and genital area, such as deficiency, cheilitis, glossitis, conjunctivitis and scrotal phlogistic, etc. , so the product can be used in the prevention and control of the disease.
Vitamin B2 storage is very limited, so every day provided by the diet.
Two properties of vitamin B2 is the main cause of the loss: (
Can be damaged by the light;
Heating can be destroyed in the alkali solution.
are a major source of food for vitamin B2 vitamin B2 is a water-soluble vitamin, easy to digest and absorb, expelled quantity with the needs of the body and may add to or omit along with the loss of protein;
It does not accumulate in the body, so every so often a sample is added by food or nutrition supplements.
Widely exists in yeast, liver, kidney, eggs, milk, soybean, etc.
vitamin B2 exist widely in all kinds of food, but usually in the animal food content is higher than that of plant foods, such as various animal liver, kidneys, heart, egg yolk, eel, milk and so on.
Many green leafy vegetables and legumes content is too much, grains and the general content of the vegetables is less.
Therefore, in order to fully meet the requirements of the body, as much as possible in addition to the use of animal liver, egg, milk and other animal foods, should eat fresh green leafy vegetables, beans and coarse rice coarse surface, and adopt various measures to minimize the vitamin B2 in the loss of food cooking, storage process main physiological functions of vitamin B2.
main mechanism of vitamin B2 vitamin B2 is mainly involved in biochemical reactions have respiratory chain energy production, amino acids, lipid oxidation, purine base into uric acid, hydroxy aromatic compounds, the synthesis of protein and some iron transport, storage and mobilization, folic acid, pyrazole aldehyde, Nick acid metabolism, etc.
1, participates in the metabolism of biological oxidation and energy, and carbohydrate, protein, nucleic acid and fat metabolism, can improve the utilization rate of the body for protein and promote the growth and development, to maintain the integrity of the skin and the cell membrane.
Has the function of protect the skin follicles mucosa and sebaceous glands.
2, participate in the growth of cell metabolism, is the body metabolism and repair of essential nutrients, such as strengthen the function of liver and regulating the secretion of epinephrine.
3, participate in vitamin B6 and nicotinic acid metabolism, is a masterpiece of B vitamins coordinating role.
FAD or FMN as a prosthetic group involved in tryptophan into niacin, vitamin B6, into the process of pyridoxal phosphate.
4, associated with the body's absorption of iron, storage and mobilization.
5, and also has antioxidant activity, enzyme - may and flavin
Centrifugal extraction machine
of vitamin B2 extraction technology of centrifugal extraction machine extract vitamin B2 is a kind of methods of extracting vitamin B2 from vitamin B2 fermented liquid.
Through the vitamin B2 found liquid calcium chloride, disodium hydrogen phosphate and sodium polyacrylate to extraction separation, flocculation, repass subsequent filtering, crystallization can get vitamin B2.
The extraction process is short, energy consumption is small, a solution, separation and crystallization can reach 98% ~ 100%, the purity of vitamin B2 extraction yield was 85% ~ 87%.
