Brief Summary

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.

Conditions

Consumer Behavior; Consumer Preference; Consumer Satisfaction

Keywords

sensory testing; intake; calories; duration of eating; rate of consumption; snack; liking; satiation; chewing; emotion; satisfaction; fullness

Outcome Measures

Primary Outcomes (10)

• Satiation: Intake in grams

  gram weight of consumption

  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.

• Satiation: Nutrition

  Intake in calories

  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.

• Duration of eating

  In minutes

  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.

• Rate of consumption

  Speed of eating in minutes

  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.

• Consumer response: Liking

  9-point hedonic scale from extremely dislike to extremely like

  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.

• Consumer response: Satisfaction

  9-point hedonic scale from extremely dissatisfied to extremely satisfied

  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.

• Perceived sensory properties (TCATA)

  Using Temporal CATA (TCATA) choose all that apply from list of crunchy, hard, tooth clogging, loose particles, soft, airy melting

  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.

• Perceived sensory properties (CATA)

  CATA

  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.

• Emotional responses using CATA

  Essence 25 using CATA

  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

  Using a 3 item Visual Analog Scale (VAS) to mark along 100 mm line the level of hunger and fullness from not at all to totally full

  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.
