Diets containing (whole) pulses have been associated with the potential to increase satiety (and acute food intake). In vitro digestion studies of pulses have shown that (thermal) processing has the potential to modulate macronutrient digestion kinetics. Changes in food (micro)strucutral properties have been identified to retard nutrient release, with a possible effect on appetite sensations. Based on distinct in vitro digestion behaviour, two differently processed pulse meals were chosen to be investigated in humans with the aim to confirm in vitro findings and gain a mechanistic understanding of the influence of structural aspects of pulses on appetite sensations.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Pulse flour | Experimental | Puree produced from pulse flours and with added oil and herbs/spices. To standardize test products on textural aspects, different levels of thickener will be added. All test products will be produced in the Future Consumer Lab at the Department of Food Science at the University of Copenhagen prior to the appetite test days. Pulse flour will be produced in the food-grade laboratory environment at the Department of Food Design and Consumer behavior and dried prior to use. |
|
| Pre-processed pulse flour | Experimental | Puree produced from pre-processed pulse flour with different structural aspects and with added oil and herbs/spices. To standardize test products on textural aspects, different levels of thickener will be added. All test products will be produced in the Future Consumer Lab at the Department of Food Science at the University of Copenhagen prior to the appetite test days. Pulse flour will be produced in the food-grade laboratory environment at the Department of Food Design and Consumer behavior and dried prior to use. |

| Pulse flour | Combination Product | Traditionally processed pulse flour in vitro digestion conditions were related to potentially influence appetite sensations. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Self-reported appetite assessment throughout the appetite test days | Visual analogue scales (VAS) will be measuring differences in perception of satiety, fullness, hunger and predicted prospective food consumption between the experimental condition compared to the control condition, with VAS 0-100 mm with 0 indicating no hunger or perceived ability to consume food / no satiety or no fullness) | 2.5 hours |
| Measure | Description | Time Frame |
|---|---|---|
| Secondary Energy Intake (kJ) of ad libitum meal | Differences in (secondary) energy intake after the test-meals at the ad libitum meal will be compared to the control condition | 30 min |
| Satiety quotient (SQ) |

| Pre-processed pulse flour | Combination Product | Pre-processing of pulse flour was related to altered in vitro digestion conditions and thus suggested to potentially influence appetite sensations. |
|
Visual analogue scales (VAS) will be measuring differences in SQ consumption before and after the experimental condition compared to the control condition (0-100 mm with 0 indicating no hunger or perccieved ability to consume food / no satiety or no fullness)
