研究概览
简要总结
To analyze prototypes developed with the base and seasonings of products that exhibit variations in chip thickness and size. The information obtained from this analysis will serve as the basis for subsequent research to explore different prototype options with increased satiation properties.
详细描述
There are two study components, a sensory study and an ad libitum study. Eighty-eight participants will test tortilla chips and eighty-eight will test extruded chips in the sensory study. On a first-come first-served basis, forty-four of the eighty-eight chip participants from the sensory testing phase will test tortilla chips, and forty-four of the eighty-eight extruded chip participants will test extruded chips in the ad libitum study.

结局指标
主要结局
Satiation: Intake in grams
时间窗: Total grams consumed at each 30-minute ad libitum testing session from beginning of eating until end of eating on separate days, two test visits for tortilla chips arm and three test visits for extruded chips arm.
gram weight of consumption
Satiation: Nutrition
时间窗: Total calories consumed at each 30-minute ad libitum testing session from beginning of eating until end of eating on separate days, two test visits for tortilla chips arm and three test visits for extruded chips arm.
Intake in calories
Duration of eating
时间窗: Timed from beginning of eating until end of eating at each 30-minute ad libitum testing sessions on separate days, two test visits for tortilla chips arm and three test visits for extruded chips arm.
In minutes
Rate of consumption
时间窗: Measured in grams per minute at each 30-minute ad libitum testing session from beginning of eating until end of eating, on separate days, two test visits for tortilla chips arm and three test visits for extruded chips arm.
Speed of eating in minutes
Consumer response: Liking
时间窗: At end of eating each product at the one 45-minute sensory session, and at end of each 30-minute ad libitum session on separate days, two visits for the tortilla chips arm and three visits for the extruded chips arm. Higher score is the better outcome.
9-point hedonic scale from extremely dislike to extremely like
Consumer response: Satisfaction
时间窗: At end of eating each product at the one 45-minute sensory session and at end of each ad libitum session on separate days, two visits for tortilla chips arm and three visits for the extruded chips arm. Higher satisfaction is a better outcome.
9-point hedonic scale from extremely dissatisfied to extremely satisfied
Perceived sensory properties (TCATA)
时间窗: Over a period of 60 seconds for each product at the one 45-minute sensory session and at each ad libitum session on separate days, two visits for tortilla chips arm and three visits for the extruded chips arm.
Using Temporal CATA (TCATA) choose all that apply from list of crunchy, hard, tooth clogging, loose particles, soft, airy melting
Perceived sensory properties (CATA)
时间窗: Check all that apply for each product while sampling them at the one 45-minute sensory session. A favorable rating would be a better outcome.
CATA
Emotional responses using CATA
时间窗: Check all that apply for each product while sampling them at the one 45-minute sensory session. Positive ratings would be a better outcome than negative..

Hunger and Fullness and how much could you eat right now
时间窗: Before eating and right after eating as much as they want to eat at each 30-minute ad libitum session on separate days, two visits for tortilla chips arm and three visits for the extruded chips arm.
