Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Eight variables on the mastication and swallowing behaviour will be extracted by the video recordings and the swallowing indications. These are: * Average bite/sip size in grams * Total eating duration in seconds * Number of chewing cycles * Chewing cycle duration * Chewing rate, the number of chews per minute * Eating rate, the amount of food in grams consumed per minute * Vertical amplitude, the vertical displacement of the chin marker * Total number of swallows | — |
Secondary
| Measure | Time frame |
|---|---|
| The secundary study parameters will be: * Frequency of consumption of the test products * Liking scores of the food the test products * Familiarity of the test products | — |
