The relation between stimulated salivary flow and the temporal consumption experience of a liquid oral nutritional supplement

Appetite. 2021 May 29:105325. doi: 10.1016/j.appet.2021.105325. Online ahead of print.ABSTRACTUse of Oral nutritional supplement (ONS) in undernourished patients has proven clinical benefits, but this can be hampered by low adherence due to poor experience of palatability. Many patients, particularly older patients, experience hyposalivation which can cause taste changes and reduce the enjoyment of foods. The aim of this study was to investigate differences in the temporal consumption experience (comprising sensory perception, in-mouth aroma release and subjective appetite) of a clinically relevant portion of ONS, for groups differing in Saliva Flow Rates (SFR). The SFR (mL/min) of thirty healthy individuals was measured on three occasions. This data was used to categorise individuals into three groups using quartile analysis: low flow (LF) (0.3-0.6mL/min, n=5), medium flow (MF) (0.7-1.2mL/min, n=16) and high flow (HF) (1.3-1.8mL/min, n=9). Over the consumption of eight 15mL sips of ONS, individuals rated their sensory perception and subjective appetite perception using line scales. Additionally, in-mouth aroma release was measured for each sip, using Atmospheric Pressure Chemical Ionisation (APCI). Compared with the MF and HF group, the LF group reported a significantly greater increase of mouth-drying over increased sips (p=0.02). The LF group also experienced significantly higher aftertaste perception (p<0.001), and more intense in-mouth aroma release (p=0.015), compare...
