Abstract
- Edible black ant (Polyrhachis vicina Roger) is a traditional edible insect species in China. It has been used as a functional ingredient in various tonics or health foods. This study determined the nutritional composition of the black ant, which included minerals, amino acids, superoxide dismutase (SOD), Vitamin E, and total acid. Supercritical CO2 fluid extraction was used to extract the organic compounds. The compounds were identified and quantified by GC-MS. Results showed that the ant powder contained 77000 IU/100g of SOD, 56.6g/100g protein, 9.0g/100g fat, 13.2g/100g volatile oil, 6.0g/100g moisture, 1.6g/100g total acid and 6.3g/100g ash. There were 18 amino acids, of which, glutamic acid, glycine, aspartic acid, alanine, leucine, proline and tyrosine were predominant. Among the 16 minerals, K, Ca, P, Mg, Fe, Mn and Zn were predominant. More than 20 organic components were identified, the main ones were 9-octadecenoic acid, ethyl oleate, cholesterol and n-hexadecanoic acid. Six of the compounds found, i.e. hexadecanoic acid, ethyl ester, linoleic acid, ethyl oleate, oleic acid and cholesta-3, 5-diene, have not been reported previously. The results indicate that P. vicina Roger is rich in nutrients and is a potential ingredient for health food.
