What is L-Alanine Powder?

L-alanine is a member of more than 20 sort of amino acids that comprise human protein. It is a neutral non-essential amino acid including carboxyl and amino groups in the molecule, and also it is also the amino acid with the highest possible content in human blood. It is an optical isomer of a-alanine, so it is additionally called L-alanine, and its molecular formula is CH, CH(NH2 )COOH. The molar mass is 89.09. The density is 1.437 (19C). The melting point is 297C. Appearance is anemic orthorhombic crystal or crystalline powder, soluble in ethanol and water, insoluble in ether and also propane, odorless and safe, with umami and also sweetness, its sweetness is 1.2 times that of sucrose.

L-Alanine Powder Uses

  1. L-Alanine Powder In skin treatment items, alanine is known to stabilize the skin’s wetness degrees, resulting in enhanced hydration. Consequently, alanine is frequently utilized in cosmetic and also moisturizing products such as foundations, creams, lotions as well as serums.
  2. L-Alanine Powder is used as preservative, flavor spices and also low-alcohol amino acid red wine in food as well as beverage, and made use of in the synthesis of amino acid infusion in medicine.
  3. L-Alanine Powder can be made use of as a flavor enhancer to boost the seasoning impact of chemical flavorings; it can additionally be utilized as a sour taste corrector to boost the sour preference of natural acids.
  4. L-Alanine Powder is made use of as a raw material for the manufacture of vitamin B6, calcium pantothenate and also other natural substances. Including it to food can boost the flavoring effect of chemical spices, boost the preference of sweeteners and also the sourness of natural acids, improve the high quality of alcoholic beverages, stop oil oxidation and also improve the flavor of dipped foods, etc. It can additionally be used as a biochemical reagent for biochemical and also microbial research.

L-Alanine Powder Application Status

Flavor enhancers can be roughly divided into the following 5 types: amino acids, flavor nucleotides, hydrolyzed animal proteins, hydrolyzed vegetable proteins, and yeast extract class A. As a food flavor enhancer, it must have safety and effectiveness, and safety is particularly important. According to the national standard GB2760-2014, there are currently 9 kinds of flavor enhancers approved for use in my country, including L-sodium glutamate and L-alanine , glycine, disodium succinate, disodium 5-star nucleotide, disodium 5-guanylate, disodium 5-inosinate, sodium saccharin, capsicum oleoresin. Sodium I-glutamate, commonly known as monosodium glutamate, is the most widely used flavor enhancer in the world. It can not only improve the flavor of food, but also promote digestion and increase appetite. It acts as the main flavor enhancer in various compound condiments , is widely used in a variety of delicious dishes and processed food centers such as canned food, fish cakes, hot sauce, sausages, etc., but with the changes in modern people’s living standards and consumption concepts, the acceptance of MSG has gradually decreased, and there has even been a talk about “MSG “The discoloration of the situation, the monosodium glutamate sales market is gradually shrinking.

Glycine has a sweet taste. It can reconcile sour and salty tastes, and basically eliminate the bitter taste of saccharin added in food. However, the amount of glycine is limited. The national standard stipulates that the addition limit in condiments and beverage products is ≤0.3%. As a non-essential amino acid, it is not easy to be absorbed and utilized by the human body after excessive intake, but it will destroy the absorption and metabolism balance of amino acids in the body, resulting in nutritional imbalance and damage to health. Capsicum oleoresin has a strong spicy taste and has a sense of moxibustion heat, which can increase the spicy taste of food and cannot be used to reconcile the taste of food. The remaining several flavor enhancers, except L-alanine, all belong to sodium salts, and when used at the maximum, they run counter to the “low sodium” life advocated at present. Therefore, the unique advantages of L-alanine as a flavor enhancer are gradually highlighted. In addition, the national standard does not limit the amount of L-alanine, which can be added according to production needs, which also improves the utilization of L-alanine in the food production process. – Feasibility of alanine to reduce the amount of MSG etc.

L-alanine has a sweet taste. It can not only improve the freshness of food, reduce the taste and sourness of food, but also ease the irritating taste such as spicy, bitter and astringent. While giving food deliciousness, it can also trigger It has a good effect on maintaining the soft taste of food; L-alanine itself does not contain sodium ions, and has higher safety in dosage; at the same time, it can participate in the metabolic cycle of amino acids in the body, amino acid The conversion process with the sugar source improves the nutritional efficacy of the food. In recent years, L-alanine has been widely used in the nutritional enhancement and seasoning of food at home and abroad. According to related reports, some Southeast Asian countries use I-alanine as an enrichment and nutritional supplement in food seasonings and beverages. , the effect is remarkable.

Preparation Method of L-Alanine Powder

1. The chlorination and also ammonification of propionic acid utilizes propionic acid as a resources. In the existence of a 3% red phosphorus driver at a temperature of 105 ° C, fluid chlorine is introduced for chlorination to produce 2-chloropropionic acid, which is then participated in an aqueous ammonia option. Using urotropine as a driver, perform ammoniation at 60 ° C to generate 2-aminopropionic acid. Lastly, the reactant is sent out into methanol option for formation, centrifuged as well as dried out to obtain the completed product of α-alanine.
2. α-bromopropionic acid chlorination approach Mix α-bromopropionic acid, ammonia water, as well as ammonium bicarbonate and also reflux for 7 hrs, after that vaporize to dryness, then take in ethanol to clean off ammonium bromide, remove the crystals, and after that decolorize and filter, Add ethanol to acquire condensation, filter and completely dry to acquire the completed product.
3. Cyanohydrin technique Acetaldehyde reacts with hydrocyanic acid to produce cyanohydrin, and afterwards reacts with ammonia to get aminonitrile; then hydrolyzes under alkaline troubles to produce salt allanate, and also obtains α-alanine via ion exchange.
