Proximate Composition and Consumption Constraints of Edible Forest Insects in Three Local Government Areas of Cross River State, Nigeria

Abstract

Proximate composition and consumption constraints of edible forest insects was studied within ten months. Data on protein, lipid, carbohydrate, crude fibre and moisture contents was obtained by collecting insect’s samples from forest and households in Akamkpa, Obubra and Ogoja in Cross River State and taken to the laboratory and analyzed. The data generated was subjected to different vigorous processes in the laboratory using approved methods. Data on constraints to insect’s consumption was obtained through administration of questionnaire to respondents. Results reveal that protein content (19.8%) was highest in termites and lowest in yam beetles (16.5%). The carbohydrates content (17.6%) was highest in ground cricket and lowest in oil palm grub (6.3%). Lipid content (18.6%) was highest in oil palm grub and lowest in grasshopper (15.1%). Ash and moisture contents were highest (16.8 and 18.6%) in grasshopper and termites, respectively, and lowest in yam beetles (14.1%) and grasshopper (13.4%). Fibre content (17.6%) was highest in locust and lowest in termites (13.4%). Consumption of edible insects in the study area is however constrained by seasons as indicated in the three locations where the study was carried out. Therefore, due to their high protein and lipid content, termites, ground cricket and oil palm grubs should be considered as important delicacies for man’s basic nutritional challenges and encourage food sufficiency. Different cultures and traditions should encourage their subjects to consume these delicacies for healthier society.
