    DL-Methionine Powder Usage and Synthesis.

    DL-Methionine is one of the essential amino acids, deficiency of which can cause liver and kidney disorders. It is especially important for protecting liver function. It can promote the growth of hair and nails, and has the effect of detoxification and enhancement of muscle activity.

    DL-Methionine Powder

    Uses and functions of DL-Methionine.

    DL-Methionine can be used as a nutritional supplement. It has the same physiological effect as L-type methionine, but is less expensive (L-type is made from DL-type), so DL-methionine is generally used.

    In oats, rye, rice, corn, wheat, peanut flour, soybeans, potatoes, spinach and other plant foods to improve amino acid balance.

    The content of commercial methionine ≥ 98.5%, is one of the essential amino acids for the growth of livestock and poultry animals, is the biological synthesis of protein "skeleton" amino acids, the animal metabolism has a strong regulatory effect, widely used in medicine, food, feed and cosmetics and other fields.

    In medicine, it can be used as the main ingredient of amino acid infusion and compound amino acid, and it can also be used to synthesise medicinal vitamins and produce liver-protecting preparations by using its anti-fatty liver effect. In food, it can be used for amino acid fortification of food and processing of food health care products, and it can be used as nutritional supplements, due to the special smell, so it is only used in fish cake products; in the feed industry, methionine has the largest amount, and it is used as nutritional fortification of feed, and it is used as feed additive to make up for the balance of amino acids, and in the varieties of amino acid-based nutritional feed additives, methionine accounts for 60%, lysine accounts for 30%, and other amino acids account for about 10 per cent. 30 per cent, and other amino acids account for about 10 per cent.

    DL-Methionine

    Characteristic of DL-Methionine.

    DL-Methionine is white flaky crystal or crystalline powder. It has special odour. Slightly sweet taste. Melting point 281 degrees (decomposition). 10% aqueous solution PH value 5.6-6.1. no spin. Stable to heat and air. Unstable to strong acid, can lead to demethylation. Soluble in water (3.3g/100ml, 25 degrees), dilute acid and dilute minus solution. Extremely insoluble in ethanol, almost insoluble in ether.

    Bulk DL-Methionine

    Product Method of  Bulk DL-Methionine Powder.

    The synthesis is usually carried out using propionaldehyde as the raw material. Propionaldehyde and methyl mercaptan are condensed in the presence of formic acid and copper acetate to form 3-methylthiopropionaldehyde. It is then mixed with sodium cyanide and ammonium bicarbonate solution.

    The reaction at 90°C gives methylthioethylglycolide. Without separation and purification, it can be heated to 180°C together with 28% sodium hydroxide solution and hydrolysed to produce sodium methionine. Neutralise with hydrochloric acid to get finished methionine. Each tonne of product consumes 480kg of propionaldehyde, 400kg of methyl mercaptan and 420kg of sodium cyanide.
