NCT07504016

Brief Summary

This study will employ a randomized, open-label, crossover design to evaluate the glycemic response to newly developed cookie formulations. A total of 20 healthy adults aged 20-70 years with a body mass index (BMI) between 18.5 and 25 kg/m² will be recruited. Participants will first complete a standard reference test using 50 g of glucose solution, followed by random assignment to consume four to five different cookie formulations in separate test sessions with a washout period of at least three days between each test. All tests will be conducted after an overnight fast, and participants will consume the test food within 10 minutes. Capillary blood glucose levels will be measured at 0, 15, 30, 45, 60, 90, and 120 minutes after consumption. In addition, sensory evaluation and subjective appetite responses will be assessed using a seven-point hedonic scale and a visual analogue scale (VAS), including appearance, flavor, texture, satiety, and expected intake. The collected data will be statistically analyzed to compare differences in glycemic index (GI) among cookie formulations and to evaluate the feasibility of developing low-GI cookies as blood glucose-friendly food products.

Outcome Measures

Primary Outcomes (3)

  • Glycemic Index (GI) Testing

    Capillary blood glucose levels will be measured after consumption of the test foods to calculate the glycemic index (GI) of each cookie formulation. Blood glucose will be monitored at multiple time points following ingestion of the test product.

    0, 15, 30, 45, 60, 90, and 120 minutes after consumption of the test food

  • Sensory Acceptability

    Sensory evaluation will be conducted using a seven-point hedonic scale (1 = dislike extremely, 7 = like extremely). Participants will rate the selected optimal cookie formulation in terms of appearance, taste, aroma, texture, and overall acceptability.

    Immediately after consumption of the test cookie

  • Subjective Appetite Assessment

    Subjective appetite responses will be assessed using a visual analogue scale (VAS). Participants will report their perceived satiety, fullness, hunger, and expected food intake after consuming the test cookie.

    15, 30, 45, 60, 90, and 120 minutes after consumption of the test cookie
