Entomophagy: A Future Feed Security System

Abstract

From the point of view of the current environmental situation which leads to non-availability of agricultural land, water resource, emission of greenhouse gases ultimately causing global warming, Entomophagy i.e. practice of eating edible insects comes as a rescue to the future feed security system. Edible insects, considered as an inexhaustible natural resource have larger food value with high content of fat, protein, crude fiber, vitamins and minerals making it nutritionally comparable with other protein sources. Some edible insects also have increased levels of omega-6 & 3 fatty acids. Studies have calculated that livestock rearing leads to about 18% greenhouse gas emission whereas barring a few insects like cockroaches, termites which produce small amount of CH4, others have practically no such harmful environmental impact. Socio- economic picture of edible insect trade comes clearly from South-East Asia with its well-established farms and trade routes. The market value for insects often exceeds from that of its other protein counterparts, as a result of which, insect farming can prove to be a rich source of income for farmers. Insect rearing requires very little technical knowledge and principal investment, so it can be taken on by anyone. In future, as prices of conventional protein rises, insects may well prove to be a cheaper source. Here in this review paper, Insect’s contribution to food security, solution to the problem of protein shortages, recent growth in demand for edible insects, consumer awareness and acceptance of insects as food has been discussed.
