Lauric arginate (LAE, ethyl-Nα-lauroyl-L-arginate hydrochloride) is synthesized from food components lauric acid and L-arginine and is quickly hydrolyzed to lauric acid and L-arginine in vivo. The antimicrobial properties and low toxicity are the basis for approval as a generally recognized as safe (GRAS) preservative at a level of up to 200 ppm in certain food products in the United States such as meat, poultry, and cheese and a safe food preservative up to 225 ppm in the European Union. These developments have generated great interest to apply LAE to improve the safety and quality of food products. In the present review, physicochemical and toxicological properties are first discussed. Antimicrobial properties and mechanisms of LAE in microbiological media, and antimicrobials used in combination with LAE aiming to achieve synergistic activities are then reviewed. The physical basis of reduced antimicrobial activities of LAE in food matrices is discussed, and studies applying LAE in meat, poultry, dairy, produce, and low-moisture foods and food-contact surfaces are summarized. Antimicrobial properties of LAE in emulsion systems and potential packaging films are also discussed for potential novel applications to improve the application in food systems. Finally, the possible impact of LAE on food sensory properties is reviewed along with some perspectives on research needs in the science and technology of LAE for use as a food antimicrobial preservative.

精氨酸月桂酸作为阳离子抗菌剂的特性和潜在的食品应用。

Lauric arginate (LAE, ethyl-Nα-lauroyl-L-arginate hydrochloride) 由食物成分月桂酸和 L-精氨酸合成,并在体内迅速水解为月桂酸和 L-精氨酸。抗菌特性和低毒性是美国某些食品(例如肉类、家禽和奶酪)中最高 200 ppm 水平的公认安全 (GRAS) 防腐剂和安全食品防腐剂批准的基础在欧盟高达 225 ppm。这些发展引起了人们对应用 LAE 提高食品安全和质量的极大兴趣。在本综述中,首先讨论了物理化学和毒理学特性。LAE 在微生物介质中的抗菌特性和机制,然后审查了与 LAE 结合使用以实现协同作用的抗菌药物。讨论了 LAE 在食品基质中抗菌活性降低的物理基础,并总结了将 LAE 应用于肉类、家禽、乳制品、农产品、低水分食品和食品接触表面的研究。还讨论了 LAE 在乳液系统和潜在包装薄膜中的抗菌特性,以寻找潜在的新应用,以改善在食品系统中的应用。最后,回顾了 LAE 对食品感官特性的可能影响,以及对 LAE 作为食品抗菌防腐剂的科学和技术研究需求的一些观点。总结了家禽、奶制品、农产品和低水分食品以及食品接触表面。还讨论了 LAE 在乳液系统和潜在包装薄膜中的抗菌特性,以寻找潜在的新应用,以改善在食品系统中的应用。最后,回顾了 LAE 对食品感官特性的可能影响,以及对 LAE 作为食品抗菌防腐剂的科学和技术研究需求的一些观点。总结了家禽、奶制品、农产品和低水分食品以及食品接触表面。还讨论了 LAE 在乳液系统和潜在包装薄膜中的抗菌特性,以寻找潜在的新应用,以改善在食品系统中的应用。最后,回顾了 LAE 对食品感官特性的可能影响,以及对 LAE 作为食品抗菌防腐剂的科学和技术研究需求的一些观点。
