Dot plot showing the association between the variance of hue (VOH) and the subjective assessment scale (SAS) in people with and without cognitive impairment and/or dementia. (SAS: 5-step ordinal subjective assessment scale. According to Schimmel et al. 2007 [8], SA1—chewing gum not mixed, impressions of cusps or folded once; SA2—large parts of chewing gum unmixed; SA3—bolus slightly mixed, but bits of unmixed original colour; SA4—bolus well mixed, but colour not uniform; SA5—bolus perfectly mixed with uniform colour. A degree of mixing of SA1 or SA2 can be interpreted as difficulties in enjoying normal meals.)
