This study is the result of a research conducted as an economic cooperation zone industry promotion project supported by the Ministry of Trade, Industry and Energy and the Korea Institute of Industrial Technology Promotion.

Recently, as competition for securing biological resources through the search and conservation of insect resources is getting fiercer, research on their value evaluation and use and development is being conducted very actively. As a part of this research, research on the development of food and pharmaceutical materials from insects is being conducted at home and abroad.

Mealworm (Tenebrionidae) is an insect belonging to the order Coleoptera, and it is commonly seen in warm and dry climates, and most of them live by eating dry and decaying plant or animal tissues. Caterpillars of this family (Tenebrionidae) have a length of about 25 mm and a cylindrical worm shape, and are often called mealworms. It is also very high, and it is a clean insect that feeds on grain.

Most of the larvae of the mealworm family are used as food for pet birds, fish, or hedgehogs. Brown mealworm, also called brown rice mealworm or Kosoae, is distributed all over the world including Korea. Brown mealworm contains abundant fat, protein, various kinds of amino acids, unsaturated fatty acids, and minerals, and the content of essential amino acids is higher than that of pork, lamb, and soybeans, and it has been reported to be similar to beef and fish.

Brown mealworm is an insect that undergoes complete metamorphosis through the stages of egg, larva, pupa and adult, but unlike other insects, the metamorphosis period is relatively short, adaptability is strong, and breeding technology is easy to learn, so it can be reared all year round. Due to such a short life history and strong survival rate, it is possible to breed at a low feed cost, and it is eco-friendly because straw and old cabbage leaves, which are rarely used during breeding, can be used as food sources.

Mealworms can be easily mass-produced and have high nutritional value, so there is a growing interest in the development of industrial uses such as feed and food. Due to its high protein content, it is widely used as food in countries such as the Netherlands and Mexico, South America, Europe, and China. In Korea, it has been widely used as pet food for about 10 years, and as insect lovers and zoos started breeding it, various advantages as an insect for feed have recently been highlighted. In addition, in 2016, mealworms were officially registered as a general food ingredient by the Food and Drug Administration, and many farms are growing for the purpose of commercialization.

However, the development of artificial feed, etc. required for rearing such brown mealworm larvae is insufficient, and in recent years, the cost of feed is high due to an increase in grain prices, and thus it is practically difficult to mass-produce.
