Cockroach Milk Emerges as Potential Superfood and Climate Solution
Scientists explore the nutritional benefits and sustainable production of cockroach milk, envisioning it in functional beverages and as a tool against world hunger.
Scientists are investigating the potential of cockroach milk as a novel superfood, citing its high protein and calorie content as beneficial for human nutrition and as a sustainable food source.
A recent review published in the journal "Insects" highlights advances in harnessing cockroach milk and other insect-derived ingredients for use in mainstream markets, particularly in functional beverages like protein shakes, teas, liquors, and beers. Researchers believe that with appropriate marketing, insect-based beverages can move beyond niche markets.
The Pacific beetle cockroach is noted for producing a "milk analogue" to feed its young. This substance is rich in protein and calories, reportedly containing three times the caloric value of bovine milk. Dr. Ramaswamy Subramanian of Purdue University, a co-author of a 2016 study on cockroach milk, has been involved in research exploring its mass harvesting potential to supplement global food supplies.
Harvesting cockroach milk presents unique challenges. The Pacific beetle cockroach is one of the few species known to give live births. To extract the "milk," researchers have had to remove embryos from pregnant cockroaches, slice them open, and collect the protein crystals.
Subramanian and his colleagues are studying the molecular structure of these protein crystals with the goal of replicating the substance. Their work has gained recognition, earning them the Ig Nobel Prize in Chemistry in 2026. This award is given for achievements that first make people laugh and then think. Subramanian expressed delight at receiving the prize, emphasizing his belief that unexpected scientific questions can lead to significant discoveries.
The research team, which includes Leonard Chavas and Nathan Coussens, has also explored the potential of other insect-derived ingredients for mainstream consumption. The prospect of using cockroach milk as a nutritional supplement and a component in various food and beverage products aligns with efforts to find sustainable solutions to global food security challenges.
