Abstract

Culture influences eating choices, attitudes, and behaviour. It alters their habits, taste, and preferences. Consumer behaviour requires understanding how cultural views, knowledge, and attitude impact food acceptance. Eating behaviour comprises what, when, and how much to eat. Understanding eating behaviour is crucial since our food choices affect both individuals and society. The objectives of the study were to understand the link between Malaysian Preferred Mouth Behaviour with their Eating Behaviour and the relationship between Eating behaviour with the BMI, age, gender, and ethnicity among Malaysian. Mouth behaviour (Individuals' particular technique of manipulating food in their mouths) and eight dimensions of eating behaviour (Hunger, Food Responsiveness, Emotional Over-eating, Food Enjoyment, Satiety Responsiveness, Emotional Under-eating, Slowness in eating) were determined from a questionnaire among Malaysian adults 18-65 years old. A total of 209 respondents with a variety of ethnicity were enrolled in this survey and categorized by their preferred oral processing behaviour. Body mass index (kg/m2> for all the demographic information and eating behaviour was evaluated. Latent Class Clustering and ANOV A were carried out to analyze the data in order to determine the actual mouth behaviour and measure the means of all the parameters. A latent class analysis with four classes was performed on the scores of the first section in the questionnaire form in order to determine the four major diverse Mouth Behaviour types among consumers. The analysis of the dimensionality of the adaptable Adult Eating Behaviour Questionnaire (AEBQ) used by Partial Least Squares-Confirmatory Factor Analysis (PLS-CF A) to reveal the weight and correlations between the appetitive traits. This perspective improves the insight into eating behaviour among Malaysian communities. Consumers' mouth behaviour (F (15,208) = 2.941; p < .05), BMI (F (15.208) = 3.737; p < .05), and age (F (15,208) = 2.482; p < .05) affected their consumption of Malaysian meals and their sensory perception. People in Malaysia chew, crunch, and smoosh a lot. Underweight populations avoid food, whereas younger age groups consume more. No race-gender relationship was found. This study can be a baseline for any product development as it provides a suitable tool to measure and classify Malaysian individuals in the Preferred Mouth Behaviour framework. All the results and observation can be used as a foundation to build future oral processing studies.
