Chemical Composition and Nutritional Value of Different Species of Vespa Hornets.


ABSTRACT: We genetically identified three different species of hornets and analyzed the nutrient compositions of their edible brood. Samples were collected from a commercial production unit in Shizong province of China and from forests near Andong City in Korea. The species were identified as Vespa velutina, V. mandarinia, and V. basalis from China and V. velutina from Korea. Farmed V. velutina and V. mandarinia were found to have similar protein contents, i.e., total amino acids, whereas V. basalis contained less protein. The V. velutina brood collected from the forest contained the highest amount of amino acids. Altogether 17 proteinogenic amino acids were detected and quantified with similar patterns of distribution in all three species: leucine followed by tyrosine and lysine being predominant among the essential and glutamic acid among the non-essential amino acids. A different pattern was found for fatty acids: The polyunsaturated fatty acid proportion was highest in V. mandarinia and V. basalis, but saturated fatty acids dominated in the case of V. velutina from two different sources. The high amounts of unsaturated fatty acids in the lipids of the hornets could be expected to exhibit nutritional benefits, including reducing cardiovascular disorders and inflammations. High minerals contents, especially micro minerals such as iron, zinc, and a high K/Na ratio in hornets could help mitigate mineral deficiencies among those of the population with inadequate nutrition.
