To analyze the influence of temperature on the flow/texture of different foods, immediately after preparation and after one hour, and 2) To compare the influence of varying the cook in food preparation, in relation to food flow. This is a quantitative and experimental study. The IDDSI standardized flow test was used to evaluate the remaining volume in the syringe and the levels of foods (porridge, smoothie, liquid soup, and pureed light soup) prepared by different cooks, in triplicate, at time zero (T0) and after one hour (T1). Differences in temperature were observed in all foods at T0 and T1 (p < 0.05). The IDDSI level changed only in porridge, from level 3 to 4 (p = 0.043). Modifications were observed in the preparation by different cooks for smoothie, on the 2nd and 3rd day (p = 0.049), from level 3 to 4 of IDDSI. In porridge, on the 1st and 3rd day (p = 0.048) and 2nd and 3rd day (p = 0.048), with a change from level 4 to 3 of IDDSI. The temperature of all foods differed within the one-hour interval, with modifications in the flow test and in the IDDSI levels, from level 3 to 4, only for porridge. Different cooks prepared the smoothie and porridge with different characteristics, resulting in changes from level 3 to 4 in both foods.
