The case for cockroach milk The next superfood?


The milk crystals of the Pacific beetle cockroach are beautiful. Slice open an embryonic roach under a microscope, and the crystals spill out in a shower of nutrient-dense glitter.But the flavour of cockroach milk is nothing to write home about. Subramanian Ramaswamy, a biochemist at the Institute for Stem Cell Biology and Regenerative Medicine in Bangalore, India, said as much early Tuesday. As a party dare — he’d lost a drinking competition — one of Ramaswamy’s colleagues once ate a sprinkling of the crystals.“He said it doesn’t taste like anything special,” Ramaswamy said.Most roaches lay eggs. Not the Pacific beetle cockroach. It gives birth to live young, sort of like humans if we kept babies by the dozen in fleshy organs called brood sacs. Also like humans, mother Pacific beetle cockroaches produce food for their offspring. The embryos dine on a liquid substance packed with fats, sugars and protein. You can think of this like cockroach milk.

It gets weirder.Insect experts have long known that this cockroach species secreted liquid food. But they thought baby roaches simply digested the stuff. When Barbara Stay, a zoologist at the University of Iowa, first stumbled upon a cache of crystals tucked inside the embryos, scientists were stumped.
We didn’t believe these crystals were actually protein crystals,” Ramaswamy said.
Close inspection of the crystals using X-rays proved otherwise. Experiments suggest that cockroach milk is among the most nutritious and highly caloric substances on the planet, according to research published recently in the journal for the International Union of Crystallography, IUCRJ. Pound-for-pound, cockroach milk crystals contain three times more energy than buffalo milk, according to the analysis by Ramaswamy and his colleagues. Buffaloes, he said, were the previous top contender for producing a protein with the most calories.
Why is the Act important?
The government has come up with this legislation at a time when there is mounting concerns over loan recovery in view of stressed assets to the tune of over Rs 8 lakh crore in the banking system. Around 70,000 cases involving more than Rs 5 lakh crore are pending in Debt Recovery Tribunals (DRT) and the proposed amendments would facilitate expeditious disposal of recovery
According to minister of state for finance Santosh Kumar Gangwar, 27 public sector banks (PSBs), which constitute 70 percent of India’s banking sector, have written off Rs 59,547 crore in fiscal year ended March 2016.
These are the cases where banks have thoroughly failed to make any recovery from the borrowers, largely corporate clients. In the last three years (FY13, 14 and 15) banks had together written off Rs 1.14 lakh crore. What this also means is so much of depositors’ money has vanished in thin air. This act will help banks to step up their recovery efforts, in turn saving taxpayers’ money.It’s a complete food,” Ramaswamy said of the roach crystals. In the brood sac, the embryos gulp down the liquid. There, the proteins turn to hard crystals in their guts. Nothing is wasted “the mouth is open and the backside is closed,” as Ramaswamy described the embryos. Within the sac, the baby roaches rely on these concentrated nutrients to grow large with an alien speed.

The discovery comes at a time when dairy milk is under increasing environmental scrutiny, as cow burps add to greenhouse gases. Alternatives like almond milk, too, have not always fared better; growing the nuts is a famously water-intensive process.So what about a roach drink? When asked if the energy-efficient cockroach crystals might end up in more human mouths, Ramaswamy described the potential as fantastic. “I could see them in protein drinks,” he said. Then he described the hurdles.Lacking nipples, cockroaches cannot be milked in the county fair sense. A cockroach-inspired thirst-quencher, if it ever existed, would more likely come via yeast, he said. Bioengineered yeast is already used in the food industry to produce synthetic sweeteners, for instance.
Plus, the roach brand is bad for business.
I don’t think anyone is going to like it if you tell them, ‘We extracted crystals from a cockroach and that is going to be food,’” Ramaswamy said. Further examination of the crystals will also tell if the roach crystals are toxic to humans.
The researchers certainly did not set out to find the next great protein shake. “In the U.S. there is a big thrust that all research has to be translational,” he said, meaning directly applicable to human health. “This was just born out of curiosity.”
