Uses and synthesis of DL-Threonine powder

DL-Threonine powder is a non-essential amino acid produced by the synthesis of threonine catalyzed by the soybean melinase. DL-Threonine is a white crystalline powder that tastes sweet and dissolves in water. Dl-threonine is dioptically active, and it contains both D-threonine and L-threonine isomers, known as DL-threonine. The preparation of DL-threonine is mainly through enzymatic synthesis. The synthesis of DL-Threonine from D-threonine and L-threonine reactants was catalyzed by soybean megalinase.

Applications/Functions of DL-Threonine powder

1. DL-Threonine powder, as a nutritional supplement, can be used in combination with glycine for white rice, with glycine and valine for wheat flour, with glycine and methionine for barley and oats, and with glycine and tryptophan for corn for optimal use. DL-Threonine, when heated with grapes, can easily produce burnt and chocolate aromas, which can enhance the aroma.
2. It is also used to synthesize L-threonine and prepare amino acid infusion and comprehensive amino acid preparation.

Physicochemical Property of DL-Threonine powder

DL-Threonine is a white crystalline or crystalline powder, odorless and slightly sweet. The melting point is about 245 ° C (decomposition). Soluble in water (20.1g/100mL,25℃), insoluble in organic solutions such as ethanol. Chemical properties are stable.

Production methodprocess of DL-Threonine powder

DL-Threonine powder was prepared by column chromatography, crystallization and acidification from glycine and acetaldehyde in the presence of excess copper carbonate under alkaline conditions.
