Primary purpose: BASIC_SCIENCE

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.

Detailed description: 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.

Eligibility criteria: Inclusion Criteria:

* Report eating tortilla and/or extruded chips regularly, non-rejector of cheese flavor chips
* Provide informed consent
* Speak and understand English without difficulty
* Willing to eat similar food the day prior and on the day of each visit to the testing facility for ad libitum sessions
* Describe yourself as generally healthy

Exclusion Criteria:

* Those who are on restricted diet due to a weight loss or maintenance purpose
* Participants with class III occlusions for ad libitum sessions
* Have abnormal taste, chewing and smell ability
* Smoke or vape
* Being pregnant or breastfeeding
* Allergic or intolerance to any of the product ingredients (section 6), especially milk and wheat
* Participation in a sensory clinical trial within past 7 days (we do not expect carryover issue from the taste testing)
* Participation in any PepsiCo trial within past 6 months

Primary outcomes:
measure: Satiation: Intake in grams
timeFrame: 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.
measure: Satiation: Nutrition
timeFrame: 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.
measure: Duration of eating
timeFrame: 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.
measure: Rate of consumption
timeFrame: 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.
measure: Consumer response: Liking
timeFrame: 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.
measure: Consumer response: Satisfaction
timeFrame: 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.
measure: Perceived sensory properties (TCATA)
timeFrame: 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.
measure: Perceived sensory properties (CATA)
timeFrame: 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.
measure: Emotional responses using CATA
timeFrame: 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..
measure: Hunger and Fullness and how much could you eat right now
timeFrame: 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.
