By including a handful of live ants to warm milk, a group of anthropologists and food researchers examined how to make “ant yogurt” — and they wound up finding out that it has the very same active ingredient as a popular kind of bread.
The germs in the “ant yogurt,” which they used a conventional Balkan approach, is a pressure that’s frequently utilized as a sourdough starter today, the group discovered. They then served the yogurt to clients at a dining establishment to display historic approaches of fermenting food.
“Today’s yogurts are typically made with just two bacterial strains,” research study co-author Leonie Jahna scientist at the Technical University of Denmark, stated in a declaration. The pressures, Lactobacillus bulgaricus and Streptococcus thermophilusare presented to warm milk as a bulk starter. The germs ferment the sugars in the milk, producing lactic acidwhich decreases the level of acidity and triggers the milk to coagulateThis likewise provides yogurt its consistency and taste.
“If you look at traditional yogurt, you have much bigger biodiversity,” Jahn stated, since different bacterial pressures impart various tastes and textures to the food.
Research study co-author Sevgi Mutlu Sirakovaa doctoral trainee at Ludwig Maximilian University of Munich, formerly collected narrative histories from individuals in Turkey and Bulgaria that explained various techniques of producing yogurt, consisting of making use of red wood ants (Formica sp.) to kick-start the procedure. The scientists checked out Sirakova’s household town in Bulgaria, where residents remembered the custom of utilizing ants to make yogurt.
“We dropped four whole ants into a jar of warm milk by the instruction of Sevgi’s uncle and community members,” research study co-author Veronica Sinottea microbiologist at the University of Copenhagen, stated in a declaration. After keeping the container of milk warm in the ant mound overnight, they attempted the yogurt that had actually formed– and explained it as “slightly tangy” and “herbaceous.”

After making the ant yogurt, the group studied it to comprehend the function of the ant “holobiont,” that includes both the ant and the microbial neighborhoods in and on the animal.
Chemical analysis of the yogurt exposed that the dominant germs accountable for fermentation was Fructilactobacillus sanfranciscensisa types that is better called an essential component in sourdough bread. Furthermore, they found plentiful formic acid in the yogurt. Wood ants produce big quantities of formic acid in their venom gland, and they can spray it as a defense reaction. The formic acid provided the yogurt a special taste and texture.
“This study highlights ants as a reservoir of bacteria with potential for food fermentation, and the importance of both ant biodiversity and traditional practices in maintaining this potential,” the scientists composed in the research study.
To even more evaluate the cooking possibilities of ant yogurt, the scientists partnered with Alchemista 2 Michelin-star dining establishment in Copenhagen. The chefs produced 3 brand-new meals from the ant yogurt: an ant-shaped ice cream sandwich, appetizing cheeses, and a “milk wash cocktail” from a dish going back to the early 1700s.
Amateur cooks need to not attempt this at home, the scientists cautioned, due to the fact that ants can harbor parasites. The scientists utilized a microbiology-grade screen to eliminate any possible parasites before passing the yogurt to the dining establishment.
Using ants in yogurt making stays prevalent in Turkey and Bulgaria today, and now researchers comprehend precisely how the ants respond with the milk to produce yogurt.
“I hope people recognize the importance of community and maybe listen a little closer when their grandmother shares a recipe or memory that seems unusual,” Sinotte stated.
