Abstract

|
|
|
To evaluate Protaetia brevitarsis as a food material, we investigated its composition of nutritional and harmful components. Analysis of nutritional composition (moisture, crude protein, crude fat, crude ash, crude fiber, and carbohydrates) showed that the content of crude protein, fat, fiber, and ash were 57.86±0.01%, 16.57±1.81%, 5.31±0.10%, and 8.36±0.10% in Protaetia brevitarsis powder, respectively. Amino acids were composed of 17.68% essential and 33.97% non-essential in Protaetia brevitarsis powder. Protaetia brevitarsis powder contained 61.10% unsaturated fatty acid with oleic acids. Additionally, Protaetia brevitarsis powder had a large quantity of minerals related to body organization, such as K (1597 mg/100 g), P (724.1 mg/100 g), Mg (366.3 mg/100 g), and so on. We also confirmed that all bacteria and all heavy metals analyzed in this study, except for very small amount of Hg (0.1±0.042 mg/kg), were not detected in the lysophilized Protaetia brevitarsis powder.
