Evaluation of nutritional and anti-nutritional values of Oryctes rhinoceros larvae in Ondo State, Nigeria

Abstract

A large number of insect species are potential sources of valuable nutrients for humans and animals but inadequate information about their nutritional values makes them to be under-utilized by humans. This study was conducted to determine the nutritional and the anti-nutritional values of Oryctes rhinoceros larvaeand samples were obtained from Ese-Odo Local Government Area of Ondo state. The proximate and the anti-nutrient compositions were analyzed. The high protein content obtained in this study makes it vital and essential as an alternative source of conventional protein-rich food especially for individuals suffering from malnutrition because of protein deficit. Phytate was revealed as a major anti-nutrient in this study but still fell below the lethal dose limit. Thus, it makes the larva consumable irrespective of the phytic acid toxicity. Oryctes rhinoceros larva can be supplemented in our diets to take care of the problem of malnutrition due to high cost of protein and other nutrient rich food particularly among the rural populations throughout the developing countries.
