Product nature
Dl-methionine is a white flake crystal or crystalline powder. It has a special smell. Slightly sweet. Melting point 281 degrees (decomposition). The PH value of 10% aqueous solution is 5.6-6.1. No optical activity. Stable to heat and air. It is unstable to strong acids and can lead to demethylation. Soluble in water (3.3g/100ml,25 ° C), dilute acid and dilute solution. Extremely insoluble in ethanol and almost insoluble in ether.
Product use
Dl-methionine can be used as a nutritional supplement. The physiological effect is the same as L-methionine, but the price is low (L-type is prepared by DL-type), so DL-methionine is generally used. In oats, rye, rice, corn, wheat, peanut powder, soybeans, potatoes, spinach and other plant foods to improve amino acid balance.
A nutritional supplement. The physiological effect is the same as L-methionine, but the price is low (L-type is prepared by DL-type), so DL-methionine is generally used. In oats, rye, rice, corn, wheat, peanut powder, soybeans, potatoes, spinach and other plant foods are restricted amino acids. Added to the above foods to improve amino acid balance. The amount required varies with the amount of cystine consumed. Adult male requirement is 1.1g/d. The taste of sea urchin is related to methionine, the sweetness of sea urchin is related to glycine and alanine, the bitterness is related to valine, and the umami is related to glutamic acid, so these amino acids can be formulated into flavouring agents. It is also used for amino acid infusion and comprehensive amino acid preparation.
