What is DL-Methionine Powder?

DL-Methionine Powder, similarly called methionine, is a vital amino acid varieties. Including methionine to feed can improve nutrients and additionally help animals proliferate in a quick time period. It is in addition a vital amino acid for animals and additionally fowl ruminants. Its main objective is to join healthy protein synthesis. The healthy protein in animal things originates from the protein in feed. Methionine is utilized as a fortifier of healthy protein feed along with a dietary additive to make up for the equilibrium of amino acids. The animals and additionally chicken ruminant feed with methionine can help the growth of animals as well as additionally chicken ruminants in a brief amount of time. The absence of methionine in pets and likewise poultry ruminants is really simple to trigger stunting, weight reduction, deteriorated liver as well as additionally kidney features, muscle degeneration, and additionally hair degeneration.

DL-Methionine Powder Uses

  1. DL-Methionine Powder can be made use of as a dietary supplement. It has the exact similar physiological result as L-methionine, however the cost is lessened (L-type is created from DL-type), so DL-methionine is normally made use of. In oats, rye, rice, corn, wheat, peanut flour, soybeans, potatoes, spinach in addition to moreover various other plant foods to improve amino acid equilibrium.
  2. DL-Methionine Powder appropriates for the avoidance in addition to therapy of liver condition and additionally arsenic or benzene poisoning, and also can also be used for the treatment of dysentery as well as additionally absence of nourishment induced by healthy protein shortage after persistent communicable illness.
  3. DL-Methionine Powder is a feed sustenance booster. The lack of methionine in animals and also chicken will set off stunting, fat burning, damaged liver and kidney attributes, muscle mass deterioration, as well as hair wear and tear. Adding 1kg of methionine to the feed is equivalent to the dietary worth of 50kg of fish meal. The basic consisting of quantity in the feed is 0,05%-0.2%.
  4. The sea urchin taste is connected to methionine, the sweetness of sea urchin is connected to glycine as well as additionally alanine, the bitterness is connected to valine, as well as the umami preference is connected with glutamic acid, and more. Consequently, these amino acids can be produced right into flavoring reps. It is still utilized in amino acid mixture and also detailed amino acid prep work.
    According to my nation’s GB2760-86 policies, it can be made use of as a seasoning.
  5. DL-Methionine Powder is among the amino acids vital for the growth of fowl as well as livestock animals. It is the “skeletal system” amino acid for biosynthesizing healthy proteins. It has a solid regulative outcome on the metabolic price of animals and additionally is generally taken advantage of in medication, food, feed as well as cosmetics. Amongst them, in medication, it can be made use of as the almost all of amino acid mixture and additionally substance amino acid, and also can similarly be made use of for the synthesis of medical vitamins. With its anti-fatty liver outcome, it can be made use of to produce liver security preparation work; in food, it can be utilized for amino acid strengthening as well as The handling of food health things can be used as a dietary supplement. As a result of the special scent, it is just made use of in fish cake products; in the feed market, methionine is utilized in the biggest quantity, along with it is used as a nutritional booster for feed to offset the equilibrium of amino acids. Feed additives, in the variety of amino acid dietary feed ingredients, methionine stand for 60%, lysine represent 30%, and also various other amino acids represent about 10%.

The Role of DL-Methionine Powder in Feed

1. Market development as well as improve making performance: Methionine can manufacture body healthy and balanced protein in pets, as well as can be promptly traded cystine to satisfy the needs of family pets; provide energised methyl groups for the body to produce choline, keratin and also nucleic acids, etc. Some methyl substances; include appropriate quantity of methionine to the animals as well as additionally chicken ruminant feed to enhance the feed conversion price and also the usage rate of healthy and balanced protein basic materials, consequently raising the advantage. Including a correct quantity of methionine to laying chicken feed can effectively increase the manufacturing performance of laying hens. Advertise hen egg production and enhance egg high quality.

2. Boost animal resistance: The degree of healthy protein and additionally amino acids in the diet regimen plan influences the immune feature of animals. Increase the material of methionine in the diet strategy, and also the antibody titer, immunoglobulin and additionally lymphocyte conversion rate in the body’s product will absolutely boost. At the same time, the degree of nutritional methionine also has an impact on mobile resistance. It can promote the absorption of numerous other nutrients in pets, hen as well as ruminants, boost resistance as well as decrease death.

3. Hepatoprotective result: Methionine is beneficial to secure the liver in the process of body metabolic process. If the consumption of methionine in the body is too decreased, the urea in addition to non-protein nitrogen in the blood will certainly increase, and also fat will conveniently be deposited in the liver.

4. Detoxing: Aflatoxin is a metabolite of Aspergillus flavus, which can create anomaly, restrain resistance and develop cancer. Methionine can incorporate with mycotoxins in feed to reduce poisoning. Methionine likewise has a repressive effect on mold and mildew and also mildew. After being included in feed, it can stop or manage the degeneration of feed nutrients by mold.

Waste Liquid Treatment Method of DL-Methionine Powder

A waste liquid treatment method for producing DL-Methionine Powder, comprising the following steps:

S1, the saponified solution is separated by a cation exchange resin to obtain a sodium sulfate mother liquor, adding a flocculant and a coagulant aid to the sodium sulfate mother liquor, adding alkali to adjust the pH value of the solution, and filtering after fully mixing to obtain a filtrate;

S2, adding an acidic solution to the filtrate for acidification, the acidified solution is concentrated and then hot filtered for solid-liquid separation to obtain sodium sulfate solid and sodium sulfate filtrate;

S3, the sodium sulfate solid is washed with desalinated water to obtain the sodium sulfate product. When the methionine content in the sodium sulfate filtrate is ≤ 1%, return to step S1 and mix with the sodium sulfate mother liquor. When the methionine content in the sodium sulfate filtrate is ≥ 1%. , enter the methionine extraction process;

S4, mixing the electrodialysis concentrated water and the reverse osmosis concentrated water, adjusting the pH and concentrating, cooling and crystallizing, and separating to obtain methionine and methionine filtrate;

S5, after merging the sodium sulfate filtrate in S2 and the methionine filtrate in S4, separate them into methionine solution and sodium sulfate solution through chromatography, return the sodium sulfate solution to S1 after concentration and removal of impurities, and merge it with the sodium sulfate mother liquor, and perform S1- S4;

S6, after mixing the methionine in S4, the methionine solution in S5 and the saponification solution in S1, stripping and deamination and promoting the decomposition of methionine intermediates into methionine;

S7, the distilled water of S2, S4 and S5 is combined and absorbed by anion exchange resin to obtain desalted water.
