¿Qué es Glyceryl Monostearate GMS (E471)? Aplicaciones, dosis, alternativas y especificaciones

Glyceryl Monostearate, abbreviated as GMS, also known as Monostearin or Glycerol Monostearate, es un nonionic surfactant produced by the esterification of glycerol with stearic acid. It es una important category of polyol fatty acid esters, with wide application value in the global industria alimentaria, pharmaceutical industry, daily chemical industry, and plastics industry. Its molecular formula is C21H42O4, and its molecular weight is 358.56. Commercial GMS typically appears as a white to amarillo claro waxy solid, flake, or polvo, odorless, con una slight fatty or sweet taste. GMS belongs to the glyceryl fatty acid ester family. Its molecular structure contiene both hydrophilic hydroxyl groups and lipophilic longchain alkyl groups. Thes unmphiphilic structure gives it excellent surface activity, enabling it to significantly reducen the interfacial tension between aceite and water phases, thus performing multiple functions incluyendo emulsification, dispersion, stabilization, lubrication, defoaming, and antistatic effects. The HLB value of GMS es unpproximately 3.8–4.2, making it a W/O emulsionante. In aditivo alimentario national standards, GMS falls under the category of mono- and diglycerides of fatty acids (INS 471). The truly emulsifying components are the monoglycerides. Common chemically synthesized GMS typically contiene about 40%-60% monoglycerides, while products refined by molecular distillation can logran monoglyceride contents of over 90%, 95%, or even 99.2%, with emulsifying power several times that of ordinary GMS. Glyceryl Monostearate was first researched in the mid19th century, logrand industrial production in the Unidaded States in 1929, and highpureza monoglyceride became disponible after the application of molecular distillation technology in 1943. Global consumption of GMS has now reached over 200,000 metric tons and continues to grow at approximately 3% per year.

Glyceryl Monostearate se reconoce como the world‘s most widely used food emulsionante, holding an irreplaceable foundation position in the modern industria alimentaria, pharmaceutical preparations, and daily chemical industry. Its most outstanding core advantages lie in its excellent multifunctionality debido a its unique amphiphilic structure, extremely high safety, and exceptionally broad application adaptability.

Excelente Emulsification and Stabilization Performance: As a nonionic surfactant, GMS significantly reducen the interfacial tension between aceite and water phases, effectively previenening aceitewater separation, fat cristallization, and protein precipitation. Whether in ice cream for fat globule dispersion, in bread dough for aceite emulsification, or in beverages for uniform suspension of ingredients, GMS plays a critical role.
