“…Likewise, the arabic gum has shown a significant effect on the surface tension of emulsions mainly due to its ability of lowering surface tension between water and oil, forming a more stable emulsion. So, a good emulsifier should be able to bind easily at the interface created during homogenization, reducing surface tension to facilitate droplet breakage (Silva et al, 2015;Dara, 2021). Based on this, the values of pH and surface tension reported in this study confirm the elaboration of a emulsion made of gum arabic/pectin with desirable stability characteristics in terms of pH-dependent surface tension (Dara, 2021).…”
