Abstract:
The invention discloses a preparation method of lauroyl Arginine ethyl ester hydrochloride, which belongs to the technical field of organic synthesis. The method comprises: reacting L-Arginine hydrochloride with lauroyl chloride in A mixed solvent consisting of water and organic solvent A, adjusting the pH value to 5-9 after the reaction is completed, centrifuging, drying to obtain lauroyl arginine; Reaction of lauroyl arginine with ethanol and thionyl chloride, after the completion of the reaction to obtain the crude product; The crude product is dissolved in organic solvent B, an alkaline aqueous solution was added to adjust the pH to 5-8, and the mixture was stirred and allowed to stand. The organic layer was taken out, cooled, crystallized, centrifuged and dried to obtain a fine product of ethyl lauroyl Arginine hydrochloride. The preparation method provided by the invention has the advantages of simple operation, less by-products, easy separation, easy drying and easy pulverization, and the main impurities in the product are effectively removed in the preparation process, high-purity fine particulate ethyl lauroyl Arginine hydrochloride can be obtained, which is suitable for large-scale production and widely used in food and cosmetic industries.

ETHYL LAUROYL ARGINATE HCL - Effect of compound preservative of ethyl lauroyl Arginine hydrochloride on fresh-keeping effect of green pepper
from VIP Journal Professional Edition
Author:
Li Yang , Tang Lingli , Xiao Xu , Feng Fengqin
Abstract:
in order to study the application effect of N ^ α-Laurol-L-Arginine ethyl ester (LAE) in the preservation of green pepper, ethyl lauroyl Arginine hydrochloride, methyl paraben sodium and chitosan were optimized and applied to the preservation of green pepper, effect of ascorbic acid content and chlorophyll content. The results showed that the optimal compound formula was that the mass concentration of LAE was 700 μg/mL, the mass concentration of methyl paraben sodium was 100 μg/mL, and the mass concentration of chitosan was 10 mg/mL. During the storage period, the optimal compound formula can significantly improve the good fruit rate of green pepper, reduce the decay index, and reduce the loss of ascorbic acid and chlorophyll in green pepper. Experiments show that LAE compound preservative has good preservative effect on green pepper.
