The quintessential French pate delicacy of foie gras cannot be called as such if it is grown in a lab, an association said Monday, after a start-up launched a high-profile bid to grow the food from duck cells.
Gourmey, a Paris-based venture, has raised $10 million (8.5 million euros) from European and US investors this month to perfect its recipe for making fattened duck liver in a lab.
Its bid has come amid growing international concern over the methods used to make the delicacy. California has outlawed foie gras sales for years and New York plans to do so next year.
But the CIFOG association, which groups together players in France's foie gras industry, countered that the venture would have no right to call their product foie gras.
"The label 'foie gras' is strictly overseen by precise regulations, both at the French and European level", it said.
This name is "authorizsd only to define a liver resulting from a duck, or a goose, fattened by force-feeding," it emphasised.
"It is therefore forbidden to use it for a product that does not result from this process," the statement concluded.
Livers for foie gras are obtained by force-feeding ducks with a tube stuck down their throats, a practice denounced by critics as unnecessarily cruel and distressing for the animals.
As well as the US restrictions, Britain prohibits foie gras production and is weighing a ban on sales, while European Parliament lawmakers proposed last month to prohibit the forced feeding of ducks or geese, another source of foie gras.
Housed in a university research lab, Gourmey has spent the past two years developing their process for faux livers able to pass muster with chefs and food fans.
With its latest funding round, Gourmey will move to a 1,000 square meter (nearly 11,000 square foot) facility in central Paris aimed at proving to investors the viability of large-scale production.
But CIFOG said: "Our conviction is that the vast majority of the French do not want to consume artificial products, synthetic chemicals resulting from cellular manipulations carried out in laboratories -- an ersatz foie gras."
Japanese researchers uncover origins of favorite Okinawan citrus fruit
Washington DC (UPI) Jul 26, 2021 -
In Japan, mandarins aren't just a tasty sweet. The nation's favorite citrus varieties, the shiikuwasha and the ornamental tachibana, hold both historical and cultural significance.
But until now, researchers weren't sure where they came from. In a new study, published Monday in the journal Nature Communications, scientists analyzed the genomes of 69 East Asian mandarin varieties, revealing the genetic origins of popular fruit.
Previous studies have traced the mandarin's genetic roots to Southern China's Hunan Province, but the latest survey yielded a surprise. Scientists found the region is home to two mandarin subspecies.
"We found that one of these mandarin subspecies can produce offspring that are genetically identical to the mother," lead study author Guohong Albert Wu said in a press release.
"Like many other plants, wild citrus typically reproduces when the pollen of the father combines with the egg of the mother, mixing the genes from both parents in the seed," said Wu, a research collaborator at the Lawrence Berkeley National Laboratory in California.
"But we found a subspecies of wild mandarins from Mangshan, in southern China, where the seed contains an identical copy of the mother's DNA without any input from a father," Wu said. "So, the seed grows to be a clone of the mother tree."
Researchers also closely examined the genetic secrets of a shiikuwasha-like citrus variety that yields small, acidic fruit. The citrus has been traditionally ignored by Japanese farmers.
Their analysis revealed the citrus to be a novel species, which they named the Ryukyu mandarin, or Citrus ryukyuensis. Unlike its relative, the shiikuwasha, the Ryukyu mandarin reproduces sexually.
The new research also revealed all shiikuwasha citrus to be hybrids of the local Ryukyuan species and another mandarin species from mainland China. Scientists determined the Mangshan subspecies was transported to the Ryukyuan islands thousand of years ago, and subsequently mate with the local Ryukyu citrus.
It turns out, Japan's shiikuwasha citrus inherited their ability to reproduce asexually from the Mangshan subspecies. This ability has allowed farmers to cultivate stable varieties like the golden shiikuwasha.
"They're all hybrids!" said study co-author Chikatoshi Sugimoto, a molecular geneticist and postdoctoral researcher at the Okinawa Institute of Science and Technology.
"The tachibana lineage also seems to have descended from the newly described Ryukyu species and another mandarin from China, but its birthplace was probably what is now mainland Japan," Sugimoto said.
The breakthrough findings have allowed scientists to identify several previously unrecognized mandarin hybrids in Japan. In the future, scientists hope their analysis will inspire the creation of new hybrids that are resilient against heat and drought.
