L-Alanine CAS NO 56-41-7 for Food Grade(FCC/AJI/USP)

Product Name:L-Alanine

CAS NO.:56-41-7

Appearance:white crystalline powder

Product Properties: By propionic acid ammoniation method (1) propionic acid chloride as raw materials, the temperature of 105 ℃ and 3% red phosphorus, in the presence of catalyst into the liquid chlorine to chloride, generate 2 – chlorinated propionic acid, and then into the ammonia solution, with methenamine as catalyst, ammoniation, under the temperature of 60 ℃ is generate 2 – amino propionic acid. Finally the reactant into methanol solution for crystallization, the centrifugal; Dry alpha alanine was finished. 2. The alpha bromine propionic acid chlorination process will alpha bromine propionic acid; Ammonia; Ammonium bicarbonate mixed reflux 7 h, then evaporation to dry, reoccupy ethanol soak wash ammonium bromide, filter out crystallization, again through filtering, adding ethanol crystallization, filtration drying product. 3. Cyanohydrin method of acetaldehyde and hydrocyanic acid reaction generated cyanohydrin, reacts with ammonia amino acrylic get; Then under the condition of alkaline hydrolysis to generate amino propionic acid sodium, L – alanine by ion exchange.

Packing:25kg/drum

used as a preservative, flavor seasoning food and beverage aspects 

1.Medicine

(1)L - Alanine is an important raw material for the synthesis of VB6, nutrients is one of the components of the filling pure amino acids nutrition infusion.
(2)L - Alanine as the main component of the amino acid injection - 800, the attending liver, brain, and help patients with hepatic coma wake up quickly, is also a kind of diuresis medicine.

2.Food additives

(1) Can improve the nutritional value of food, in all kinds of food and beverages, such as: bread, water ice point, fruit tea, milk, soda, sorbet, and so on.Add 0.1 ~ 1% of alanine can obviously improve the utilization rate of the protein in food and beverage, and because the alanine has the characteristics of can be absorbed by the cells directly, therefore, after drinking can quickly restore fatigue, refreshing.
(2)Artificial sweeteners to improve the sense of taste, can make the sweetness efficiency, reduce the dosage.In compound with sweet mei agent of 1 ~ 10% of alanine, can improve the sweetness, sweet, soft as natural sweet mei agent, and can improve the taste.
(3)Alanine or synthetic high sweetness, sweet, Alitame, L - asp acyl - D - propylene ammonia amide, 600 times of sucrose sweetness) one of the raw material.
(4)Biochemical research.Tissue culture.Determination of liver function.
(5) Used as a flavoring agent.Can add spice seasoning effect;Correction also can be used as sour agent, improve the sour taste of organic acid.
(6) L-Alanine is mainly used as nutritional supplement and flavoring in food processing industry. It can also be used in the medical industry.
(7)  L-Alanine is function of antioxidation can be used in food processing. For instance, it can be used in oils, yolk jam, purified foods, sauce-pickled foods, and bra -pickled foods. It can both protect them from oxidation and improve their flavor;
(8) L-Alaninecan be used as a raw material for Vitamin B6 synthesis and material for the research on metabolism of amino acids by medical organisms or on a biochemical basis.
