Texture profile analyzes and color measurement of fermented buttermilk available on the Polish market and their classification according to IDDSI

Based on the manufacturer's data, the following information was entered: taste, fat content (including saturated fatty acids), carbohydrates (including sugars), protein, salt. The following texture parameters were instrumentally measured: firmness, consistency, cohesiveness, and work of cohesion.

The color coordinates L, a*, b* and X, Y, Z were measured in the SPIN and SPEX system. On the basis of the L coordinates (lightness), a* and b*, the following were calculated: (WI) white index, (YI) yellowness index, (C) chroma, (BI) brownness index. IDDSI Flow Test: syringe flow test developed by the International Dysphagia Diet Standardization Initiative (IDDSI); Level 0 Thin (0–1 mL liquid remaining), Level 1 Slightly-Thick (1–4 mL), Level 2 Mildly Thick (4–8 mL) and Level 3, Moderately Thick (8–10 mL).
