摘要：
The long-term hydrolysis and isomerizations that occurred in commercial glycerol monostearate (GMS) have been studied under controlled low relative humidity (ca. 30%) and high relative humidity (ca. 90-100%). Acid number values increased 2-3 units over an 84-day period in high relative humidity, and only 0. 5 unit in low humidity. Changes in the total alpha -monoglyceride, beta -monoglyceride, alpha , alpha prime - and alpha , beta -diglyceride concentrations with time offered a method to observe the processes involved.
