The SFT showed a better relationship ( R 2 = 0.928) than LST ( R 2 = 0.825), indicating that the former can predict the viscosity better in the range for nectar-like consistency. Plots comparing η a, 50 with SFT or LST values showed good exponential relationships between the measurements. ![]() CTBs were also measured via the line-spread test (LST), and the flow distance value (cm) by LST and the volume remaining (mL) in the syringe by SFT was correlated with the apparent viscosity ( η a, 50). We prepared cold thickened beverage (CTB) samples with different thickener concentrations and measured them by extrapolating the viscosity range (51–350 mPa Commercial cold beverages thickened with a xanthan gum (XG)-based food thickener were examined at different thickness levels by using the simple, cost-effective syringe flow test (SFT) developed by the International Dysphagia Diet Standardization Initiative (IDDSI). ![]()
