Latest research suggested that chock packed with protein, the insect milk could one day be changed into a food supplement valuable for human intake.

Scientists have discovered that the Pacific Beetle Cockroach feeds its bug little ones an extraordinarily rich in protein, fat and sugar formula. Though for anytime soon it can’t be expected in the market.

Becky Facer, director of school and educator programs at Fernbank Museum of Natural History in Atlanta said any liquid taken from a cockroach isn’t true milk. This is because the insect liquid gets transformed into protein crystals in the guts of infant cockroaches.

One of the study researchers Leonard Chavas, said for the cockroach baby the protein crystals are milk. It is very important for their proper growth and development. He added the crystals carry three times the energy of an equal mass of buffalo milk, nearly four times the equal of cow’s milk.

Chavas along with his colleagues analyzed the species, also called Diploptera punctata, the sole species of cockroach that is viviparous. The species can bring forth live babies developed inside the mother's body, rather than the mother laying eggs to develop out of her body.

Akin other viviparous creatures, the species of roach feed its developing embryos with a protein-rich liquid produced by its brood sac.

Once the embryo ingests the liquid, development of protein crystals takes place within its midgut. Chavas along with his fellow members took out one of such crystals to get more information about it and the potential nutrition present in it. They conducted tests and did genome sequencing, and found that it was a complete food. Chavas said, “It is what one would need: protein, essential amino acids, lipids and sugars”.
