abstract = {This study aimed to analyze the effect of glycerin monostearate (GMS) on the emulsion stability of recombined dairy cream (RDC) formed with micellar casein (MCN), calcium caseinate (CaC) or sodium caseinate (NaC). The results showed that GMS could change the particle size distribution of lipids droplets by co-adsorbing onto the oil-water interface together with caseins and consequently the emulsifying stability of RDC. For MCN-RDC, a significant increase was observed in the phase separation time after GMS addition, and 2.5% MCN-RDC exhibited the best emulsion stability and an increase in the phase separation time from 474 to 4622 s. The phase separation time of 0.5%–2.0% CaC-RDC was in the range of 167–483 s, and increased to 177–517 s after GMS addition, whereas that of 2.5% CaC-RDC decreased slightly. The phase separation time of 0.5% NaC-RDC increased from 1245 s to 1460 s after GMS addition, while that of NaC-RDC with NaC concentration higher than 1.0% decreased. In conclusion, GMS can increase the emulsion stability of MCN-RDC, and its effect on the emulsion stability of CaC-RDC and NaC-RDC differs depending on the concentration of caseins. GMS can increase the emulsion stability of RDC only when the concentrations of CaC and NaC were 0.5%–2.0% and 0.5%, respectively.}
