Would you eat bug butter?

Scientists at Ghent University in Belgium are experimenting with larva fat to replace butter in waffles, cakes and cookies, saying using grease from insects is more sustainable than dairy produce.

To make the bug butter, researchers soak larvae — maggots — from black soldier flies in a bowl of water, put it in a blender to create a smooth greyish dollop and then use a kitchen centrifuge* to separate out insect butter.

“There are several positive things about using insect ingredients,” said Daylan Tzompa Sosa, who oversees the research.

“They are more sustainable because (insects) use less land (than cattle), they are more efficient at converting feed … and they also use less water to produce butter,” Tzompa Sosa said as she held out a freshly baked insect butter cake.

According to the researchers, consumers* notice no difference when a quarter of the milk butter in a cake is replaced with larva fat. However, they report an unusual taste when it gets to fifty-fifty and say they would not want to buy the cake.

Insect food has high levels of protein*, vitamins*, fibre* and minerals* and scientists elsewhere in Europe are looking at it as a more environmentally friendly and cheap alternative to other types of animal products.

Would you eat butter made from maggots?


  • centrifuge: an appliance that spins something at high speed so different parts (such as fat and water) separate
  • consumers: people who consume, eat, drink or buy
  • protein: fuel source that animals need to repair and build body tissue
  • vitamins: micronutrients that living things need to function properly. Examples are vitamin C and D
  • fibre: part of plant food that can’t be completely broken down by the body; also called roughage
  • minerals: pure micronutrients that living things need to function properly. Examples are magnesium and potassium
