Satiety Evaluation of Mature Okra Flour-incorporated Biscuit (MOFB)
Evaluating the Impact of Mature Okra Flour-Incorporated Biscuits (MOFB) on Perceived Satiety Through the Satiety Labeled Intensity Magnitude (SLIM) Scale and Metabolomic Approach
This study aims to evaluate whether eating biscuits made with mature okra flour can help young adults feel fuller (enhance satiety) and change certain blood markers compared to eating standard biscuits.
Mature okra is a nutrient-dense agricultural by-product that is often discarded due to its tough texture. For this study, mature okra pods are dried and ground into a flour, which is then used to replace 10% of the wheat flour in a custom biscuit formulation.
Participants will take part in a single-blind, randomised trial where they will consume either the okra-incorporated biscuits or the standard control biscuits on separate occasions. Researchers will measure participants' perceived fullness over 165 minutes using a visual rating scale. Blood samples will also be collected at specific intervals during this time to evaluate blood glucose levels, appetite-related hormones, and metabolic responses.

Expérimental: Mature Okra Flour-incorporated Biscuit (MOFB) Group
Young adult participants assigned to this group will consume the functional biscuit formulation incorporated with mature okra flour.
Perceived satiety, metabolomic profiles, and appetite signalling will be assessed post-ingestion.
|
Standard biscuit formulation manufactured where 10% of the wheat flour is substituted with mature okra flour, designed to enhance the nutritional profile while maintaining acceptable sensory scores.
|
|
Comparateur actif: Control Biscuit Group
Young adult participants assigned to this group will consume the standard control biscuit formulation made with 100% wheat flour.
Perceived satiety, metabolomic profiles, and appetite signalling will be assessed post-ingestion.
|
Standard biscuit formulation manufactured using 100% wheat flour, designed to match the sensory profile and appearance of the experimental biscuit without the inclusion of mature okra flour.

Satiety Response
Délai: Baseline (0 minutes) and post-consumption at 15, 45, 75, 105, 135, and 165 minutes
|
The satiety response after biscuit consumption will be determined by the Satiety Labeled Intensity Magnitude (SLIM) scale.
The SLIM scale consists of a 100mm vertical line with labelled phrases to indicate satiety: "greatest imaginable fullness", "extremely full", "very full", "moderately full", "slightly full", "neither hungry nor full", "slightly hungry", "moderately hungry", "very hungry", and "extremely hungry", and "greatest imaginable hunger".
The first satiety survey is filled before breakfast (time 0), and the remaining surveys at 15, 45, 75, 105, 135 and 165 min later.

Baseline (0 minutes) and post-consumption at 15, 45, 75, 105, 135, and 165 minutes
|
|
Change in Plasma Insulin Concentration
Délai: Fasting state (0 minutes), 75 minutes, and 165 minutes post-consumption
|
Plasma concentration of insulin will be measured using an enzyme-linked immunosorbent assay (ELISA) kit.

Ad Libitum Energy Intake at a Subsequent Meal
Délai: At the end of the satiety evaluation session (165 minutes post-biscuit consumption)
|
Following the 165-minute satiety evaluation session, participants will be served an ad libitum meal consisting of fried rice and requested to consume as much as they want until comfortably full.
The weight of the food consumed will be calculated by subtracting the remaining food weight from the initial served weight using a digital weighing scale (accurate to 1.0 g).
Total energy intake will be calculated by multiplying the weight of the food consumed by the specific caloric content of the fried rice (expressed in kilocalories).
