At CMC concentrations above 0.2%, the sedimentable fraction was much smaller than those without CMC and with 0.1% CMC. The above experimental results were in good agreement with our long-term visual observation. At CMC concentrations above 0.3% CMC, almost no sedimentation or creaming could be observed, thus clearly indicating that CMC can stabilise the milk system in the presence of a large amount of fat as did in the skim milk
