Entomophagy is termed as the practice of eating insects as a food, and considered as an alternative remedy of the global problems of food shortage and protein deficiency. The potential of the insects for feed or food materialization was investigated among edible insects locally available. European honeybee (Apis mellifera), larvae of Oriental giant wasp (Vespa mandarinia), giant field cricket (Teleogryllus emma), larvae of Korean horned beetle (Allomyrina dichotoma) and mealworm (Tenebrio molitor) were subjected for the standard nutritional analysis. Comparing with the standard food materials (egg, beef and soybean), all insects showed comparably high protein contents (46.1~70.5 % dry mass) and crude ash contents (2.7~6.3%). Carbohydrate contents were higher than egg or beef but lower than soybean. All insects showed higher mineral contents, especially high K/Na ratio. Among fatty acid components, high linoleic acid, essential fatty acid and unsaturated fatty acid showed promising potential for further development as functional food materials or processed food ingredients. However, further researches are demanding for processing and food safety issues, for example, on allergenic responses as well as legislative listing as food material.
