采用薄层色谱法（TLC）和液相色谱-质谱法（LC-MS）对日本市售硬脂酰乳酸钠（SSL）的成分进行了测定和鉴定。使用TLC和硅胶色谱法纯化硬脂酰乳酸酯（SL）和硬脂酰-2-乳酸酯（SLL），以获得标准品。结果表明，SSL由乳酸（8.4%）、硬脂酸（15%）、SL（57%）和SLL（13%）组成。使用LC-MS测定游离乳酸、源自SL的乳酸和源自SLL的乳酸的总量。平均值约等于使用JECFA方法测定的值。这是首次使用TLC和LC-MS测定和鉴定日本购买的SSL组分的研究。
The components of commercial sodium stearoyl lactylate (SSL), purchased in Japan, were determined and identified using thin layer chromatography (TLC) and liquid chromatography with mass spectroscopy (LC-MS). Stearoyl lactate (SL) and stearoyl-2-lactylate (SLL) were purified using TLC and silica gel chromatography to obtain standards. The results show that SSL consisted of lactic acid (8.4%), stearic acid (15%), SL (57%), and SLL (13%). The total amounts of free lactic acid, lactic acid derived from SL and lactic acid derived from SLL were determined using LC-MS. The mean value was approximately equal to that determined using the JECFA method. This is the first study to determine and identify the components of SSL purchased in Japan, using TLC and LC-MS.
