INTRO: Chef-turned-chemist Vayu Hill-Maini has a passion: to turn food waste into culinary treats using fungi.
One of his collaborators is Rasmus Munk, head chef and co-owner of the Michelin two-star restaurant Alchemist in Copenhagen, who serves a dessert — orange-colored Neurospora mold grown on rice — inspired by Hill-Maini.
For the past two years, Hill-Maini has worked with a team of chefs at Blue Hill at Stone Barns, a Michelin two-star restaurant in Pocantico Hills, New York, to generate tasty morsels from Neurospora mold grown on grains and pulses, including the pulp left over from making oat milk. At Blue Hill, you may soon be served a patty of grain covered with orange Neurospora with a side of moldy bread — orange Neurospora grown on rice bread that, when fried, smells and tastes like a toasted cheese sandwich.
That's only the beginning for Hill-Maini, a Miller postdoctoral fellow at the University of California, Berkeley. Working in the lab of Jay Keasling, UC Berkeley professor of chemical and biomolecular engineering, he has devoted himself to learning everything there is to know about Neurospora intermedia — a widespread fungus that is traditionally used in Indonesia to make a food called oncom (pronounced ahn' cham) from soy pulp — so it can be adapted broadly to Western food waste and Western palates.
"Our food system is very inefficient. A third or so of all food that's produced in the U.S. alone is wasted, and it isn't just eggshells in your trash. It's on an industrial scale,” said Hill-Maini. “What happens to all the grain that was involved in the brewing process, all the oats that didn't make it into the oat milk, the soybeans that didn't make it into the soy milk? It's thrown out."
When a fellow chef from Indonesia introduced him to fermented oncom, he said it struck him that "this food is a beautiful example of how we can take waste, ferment it and make human food from it. So let's learn from this example, study this process in detail, and maybe there's broader lessons we can draw about how to tackle the general challenge of food waste."
Hill-Maini's evangelizing about the benefits of Neurospora inspired Blue Hill to install an incubator and tissue culture hood in its test kitchen this summer, allowing the restaurant to dive more deeply into fungal foods. Before, Luzmore, chef in charge of special projects, FedExed various substrates to Hill-Maini's lab at the Joint BioEnergy Institute (JBEI) in Emeryville, California, near UC Berkeley, where Neurospora magically transformed them for study. Luzmore has tasted many Neurospora experiments, though his favorite is made from stale rice bread.
"It’s incredibly delicious. It looks and tastes like you grated cheddar onto bread and toasted it," Luzmore said. "It's a very clear window into what can be done with this."
While people from many cultures have long eaten foods transformed by fungi — grain turned into alcohol by yeast, milk curds turned into blue cheese by Penicillium mold, soy sauce and miso produced from soybeans by koji mold (Aspergillus oryzae) — oncom is unique in being produced from waste food. Developed by native Javans long ago, it appears to be the only human food fermented solely by Neurospora mold. But not for long.
A paper by Hill-Maini about the genetics of the Neurospora intermedia strains that transform soy milk waste into oncom, and how the fungi chemically alter 30 different kinds of plant waste, will be published online Aug. 29 in the journal Nature Microbiology.
"In the last few years, I think, fungi and molds have caught the public eye for their health and environmental benefits, but a lot less is known about the molecular processes that these fungi carry out to transform ingredients into food," he said. "Our discovery, I think, opens our eyes to these possibilities and unlocks further the potential of these fungi for planetary health and planetary sustainability." (MORE - details, no ads)
