Exploring multi-ethnicity consumer acceptance of migratory locust (Locusta migratoria)-based food products: a survey of Malaysian consumers

Abstract

A cross-sectional survey research design was chosen to explore the degree of acceptance of Malaysian consumers from various demographic backgrounds towards migratory locust-based food products by using the Food Neophobia Scale (FNS), Insect Phobia Scale (IPS), and Willingness to Consume (WTC) migratory locust-based food products scale. This study chose migrant locusts (Locusta migratoria) due to their high protein content and potential to obtain Halal certification and sustainable production. In this study, 326 questionnaires were distributed online using non-probability sampling methods among Malaysian consumers. The results showed that average mean values for total FNS, IPS, and WTC scores were 35.73 out of 70, 31.05 out of 42, and 4.27 out of 7, respectively. In addition, the correlations between FNS and IPS scores towards WTC scores showed a negative correlation, with the IPS-WTC (-0.399) correlation being stronger than FNS-WTC (-0.216). Regarding demographic background, statistically significant variables for total FNS and IPS scores were limited to age group and gender. Overall, it can be concluded that most respondents hold a neutral stance towards introducing migratory locust-based food products in Malaysia, with entomophobia being the most probable reason for consumers' rejection of migratory locust-based food products.
