Spicy Food Study

​The food spiciness study aims to determine the impact of oral burn on oral processing behaviour of solid foods (burger patty and curried rice). For this study we are looking for at least 50 subjects. The study will start from May 3 (2021) to June 30th (2021).

The study consists of four sessions. The first session (30 min) is an online information session. The following 3 sessions (each session: 45 min) you will visit Helix building (sensory lab) on Wageningen campus for the actual test sessions.

What's in return?

After completion of all four sessions, you will receive a financial compensation of €30, - paid as VVV vouchers.

    • Then you taste and report burn intensity, hardness and affective response of meals.
    • Subsequently, you are video recorded while consuming meals.
