| description | Insects represent a sustainable, protein-rich food source widely consumed in Asia, Africa, and South America. Eating <i>Clanis bilineata tsingtauica</i> Mell is common in the eastern part of China. A comparative characterization of nutrients in the meat and epidermis of <i>C. bilineata tsingtauica</i> was performed in this study. The results showed this insect to be high in nutrients, particularly in the epidermis where protein total was 71.82%. Sixteen different amino acids were quantified in <i>C. bilineata </i><i>tsingtauica</i>, and the ratio of essential to nonessential amino acids in the epidermis and meat was 68.14% and 59.27%, respectively. The amino acid composition of <i>C. bilineata tsingtauica</i> is balanced, representing a high-quality protein source. Eight minerals were quantified in <i>C. bilineata tsingtauica</i>, including four macro and four trace elements. Fe in the epidermis and Zn in the meat were abundant at 163.82 and 299.31 μg/g DW, respectively. The presence of phytic acid impacted the absorption of mineral elements in food. We also detected phytic acid in <i>C. bilineata tsingtauica</i>. The molar ratio of phytic acid to zinc (PA/Zn) in <i>C. bilineata tsingtauica</i> was very low (3.28) compared to <i>Glycine max</i> and <i>Cryptotympana atrata</i>, which indicated that mineral utilization was high. In conclusion, this study confirms that <i>C. bilineata tsingtauica</i> is a highly nutritious food source for human consumption, and the results provide a basis for further consumption and industrialization of this edible insect. |
