Monosodium glutamate (MSG) is a flavor-enhancing compound used to elevate the flavor profiles of various foods. This flavor enhancer is the sodium salt of L-glutamic acid and is widely used in foods, such as flavorings, seasonings, sauces, and instant soups. The potential health effects of MSG consumption, particularly the health issues that excessive consumption could lead to, have been the focus of social concerns. It is stated that excessive consumption of MSG can cause cardiovascular diseases, obesity and diabetes, kidney damage, hypertension, anxiety, and memory impairment. The maximum permissible amount of MSG in foods is set at 10 g/kg according to the Turkish Food Codex. The aim of this study is to develop an appropriate method for analyzing the MSG content within the various food samples like flavorings, seasonings, and spices sold in Turkish local markets. The validation parameters of the developed method were examined and it was found that the developed method corresponds to the recommended values. The limit of detection and the limit of quantitation values were calculated as 4.78 ng/mL and 15.93 ng/mL, respectively. Recovery % was determined to be 100.96% in intra-day and 132.22% in inter-day analyses for the precision of the method. The results compared to the values specified in the Turkish Food Codex Food Additives Regulation and samples that purportedly did not contain MSG on their labels were found to contain MSG.
味精（MSG）是一种用于提升各类食品风味的增味化合物。这种增味剂是L-谷氨酸的钠盐，广泛应用于食品中，如调味剂、调味料、酱汁和速溶汤等。食用味精对健康的潜在影响，尤其是过量食用可能导致的健康问题，一直是社会关注的焦点。据说过量食用味精会导致心血管疾病、肥胖和糖尿病、肾脏损伤、高血压、焦虑和记忆障碍。根据土耳其食品法典，食品中味精的最大允许量设定为10克/千克。本研究的目的是开发一种合适的方法，用于分析在土耳其当地市场销售的各种食品样品（如调味剂、调味料和香料）中的味精含量。对所开发方法的验证参数进行了检查，发现所开发的方法符合推荐值。检测限和定量限分别计算为4.78纳克/毫升和15.93纳克/毫升。该方法日内精密度的回收率为100.96%，日间精密度的回收率为132.22%。与土耳其食品法典食品添加剂法规中规定的值相比，结果发现标签上声称不含味精的样品中含有味精。
