Abstract:

In order to reveal the effect of monoglyceride dosage on the physical properties and crystal texture of organogels,a texture analyzer,a rheometer,a pulse nuclear magnetic resonance spectrometer,a differential calorimeter scanner and a X-ray diffractometer were adopted to evaluate the rheological properties,solid fat content,melting properties and crystal morphology of organogels.The results show that the change of monoglyceride content can change the number and type of crystals,thus changing the physical properties of organogels from a macro perspective.Through the analysis of the strength,hardness and crystal shape of the system,it is found that the organogel prepared at 80℃ and 12% of monoglyceride amount shows a better structure performance and can meet the actual production needs and applications.

Key words: organogelator, organogel, monoglyceride, physical properties, crystal texture
