Consent to participate
All adult participants have freely given consent to participate in the sensory and groundnut intake assessment of consumers. There were no children below the age of 18 years included in the sensory evaluation. However, for the groundnut intake assessment of consumers, consent to engage the children were obtained from their parents or guardians. All listed participants were approved by the Sokoto Health Research Ethics Committee, Ministry of Health, Sokoto, Sokoto State, Nigeria. Then the participants spontaneously participated in the sensory evaluation as well as the groundnut intake assessment.
Consent to publication
