L-Phenylalanine Powder Usage and Synthesis.

L-Phenylalanine is an essential amino acid that cannot be synthesised by the body. It is almost non-restricted amino acid in the protein of most foods. It can be added to baked goods, and in addition to fortifying phenylalanine, it can improve the flavour of food by reacting with sugar in an amino-carbonyl reaction. It is mainly used as the synthetic raw material of food sweetener aspartame in food industry; it can also be used as nutritional supplement. Refined Pharmacopoeia Grade L-Phenylalanine is used to formulate compound amino acid infusion.

Uses and functions of L-Phenylalanine.

Nutritional supplement. One of the essential amino acids. Almost non-limiting amino acid in the proteins of most foods. Can be added to baked goods, in addition to strengthening the phenylalanine, and sugar and amino carbonyl reaction, can improve the aroma of food. It can also be used to prepare amino acid infusion and comprehensive amino acid preparations.

L-Phenylalanine is one of the essential amino acids and can be used as amino acid raw material medicine. It is mainly used in functional food additives as a nutrient fortifier, amino acid infusion and as a component of comprehensive amino acid preparations. It is the raw material of many kinds of anticancer drugs and dipeptide sweetness, used in biochemical research, the preparation of culture medium, and used as amino acid nutritional drugs in medicine.

Characteristic of L-Phenylalanine.

Colourless to white flaky crystals or white crystalline powder. Slightly special odour and bitter taste. Melts and decomposes at about 283°C. The pH value of 10% aqueous solution is 5.4-6.0. It is stable in heat, light and air. Colouring when heated with glucose. Unstable in alkaline.

Soluble in water (3g/100ml, 25℃). Difficult to dissolve in ethanol, dilute inorganic acids and alkaline solutions. One of the essential amino acids. Its physiological role is related to tyrosine.

May affect thyroid hormones and melanin in hair and skin.D-type has the same physiological effect as L-type. Minimum requirement (mg/kg?d): adult men 31; young children 169.

Poduction Method of Bulk L-Phenylalanine Powder.

Phenylalanine is prepared synthetically in low yields and is usually extracted from natural products. The defatted soybeans are hydrolysed with hydrochloric acid to remove the acidic amino acids, and the phenylalanine and tyrosine are adsorbed with activated charcoal or decolorising resin. The phenylalanine is then solubilised and separated with a solvent. The method of first converting phenylalanine in the hydrolysate to 2,5-dibromophenylsulfonate and then separating it from leucine, arginine and other amino acids by using the difference in solubility can also be used.
