Unraveling the physicochemical attributes of three cricket (

Disgust and neophobia elicited by whole insect products, has necessitated the need to mask insect-based food products. The physico-chemical parameters, sensory acceptance, and willingness to pay (WTP) for wheat biscuits supplemented with cricket powder was evaluated. The biscuits' color intensity correlated with the cricket inclusion levels. Spread ration of cricket-enriched-biscuits increased (1.0-1.2-folds), while the hardness and fracturability decreased (1.0-1.3-folds and 1.0-1.2 folds, respectively) compared to the control biscuit. Cricket-biscuits exhibited 1.2-1.7, 1.1-3.7, 1.2-3.0 and 1.1-1.2-folds higher (p < 0.05) protein, ash, fiber, and fat, respectively. Ca, Fe, and Zn were 1.1-3.7, 1.1-1.2 and 1.4-4.0-folds higher, respectively, for cricket-based biscuits. Monounsaturated and polyunsaturated fatty acids proportionally increased with increasing cricket flour. On a likert scale, 71.4%, 71.9%, 38.4% and 57.5% of the caregivers and 38.6%, 58.3%, 40.0% and 34.0% for children (3-5 years) strongly preferred the color, texture, taste and aroma, respectively, of the cricket-based biscuits. Forty-seven (47%) of the caretakers were WTP a premium of 37 Kenyan shillings (0.34 USD) for cricket-based biscuits. Our findings demonstrated that integration of cricket flour into existing market-driven consumer familiar food products significantly increased acceptability and WTP, thus promising potential to contribute to improved food and nutritional security.
