Brief Summary
Based on in vitro studies identifying changes in food structures potential to delay digestion as well as results from animal studies showing potential of these foods to decrease appetite, nano-particulated whey protein and high molecular weight whey protein-alginate coacervates were chosen to be investigated in humans. Thereby, the aim of this short-term study is to investigate if nano-particulated whey protein has appetite reducing effects in humans compared to non-particulated whey protein (Part 1) as well as if high molecular weight whey protein-alginate coacervates have appetite reducing effects in humans compared to calcium alginate (Part 2).

Outcome Measures
Primary Outcomes (1)
24-hour energy intake (kJ)
Difference in 24-hour energy intake (the total energy intake from the test products, the ad libitum lunch and the ad libitum snack box) between exposure to the experimental conditions compared to the matching control conditions.
24 hour
Secondary Outcomes (5)
Energy intake (kJ) at each of the ad libitum meals
Lunch: 30 minutes; Snack box: from 12.00 pm until going to bed (app. 11 hour)
Visual analogue scales (VAS) of self-reported appetite assessed throughout the appetite probe days while being in the laboratory
3 hour
Satiety quotient (SQ)
30 minutes
Visual analogue scales of self-reported nausea and well-being assessed throughout the appetite probe days while being in the laboratory
3 hour
Visual analogue scales of self-reported product palatability
5 minutes (assessed after both exposures at each appetite probe day)
Study Arms (2)
High molecular weight whey protein-alginate/Calcium alginate
EXPERIMENTALProduced from whey protein with different structures (nano-particulated vs. non-particulated whey proteins and high molecular weight whey protein-alginate coacervates vs. calcium alginate) added cream, sucrose and lactose in order for the products to contain all macronutrients and in equal amounts between the intervention and the control products. Additionally, vanilla flavour (Dr. Oetker vanilla extract) is added in order for the test products to taste similar to "koldskål" (a well-known Danish food). All test products will be produced in the dairy pilot plant at Department of Food Science at University of Copenhagen prior to performance of the appetite probe days. All test products will have a pH of 4 and will be manufactured from dry (powdered) ingredients and pasteurized cream. They will be kept refrigerated for a maximum of 3 days prior to use and production will be planned accordingly.

Interventions
Different particularisations of whey protein were identified to potentially delay digestion based on in vitro studies and to potentially affect appetite and body weight based on animal studies compared to non-particulated whey protein, with nano-particulated whey protein suggested to be more efficient than micro-particulated.
Different whey protein-alginate coacervates were identified to potentially delay digestion based on in vitro studies and to potentially affect appetite based on animal studies compared to calcium alginate, with high molecular weight alginate suggested to be more efficient than low molecular weight alginate.
