Insect based proteins as feed and food sources: Literature review on emerging technologies and possible associated risks

Abstract

The world needs more protein for the ever-increasing population. The traditional production of meat is responsible for a large part of greenhouse gases and pollution. Compared to the production of animal protein, insect-based protein gives lower emissions and requires fewer natural resources such as water, space, energy, and feed. This is novel food with an emerging industry. There has been a concern about whether the insects could bring biological or chemical damage to humans, eaten whole or use them as additions to food or a feed. It was also assessed whether the climate benefits and the good degree (effectiveness) of utilisation would outweigh any disadvantages that might be found.
