A recent international study, presented at the 2024 American Chemical Society spring meeting, has revealed that there are four distinct species of edible ants with unique flavors. These ants have the ability to give dishes a rich and aromatic profile, making them a tasty, nutritious, and sustainable addition to menus. Although insects are often viewed as unwelcome picnic guests, they are a common ingredient in some parts of the world. Ants are roasted or ground to add flavor and texture to various dishes.
Changqi Liu, an associate professor of food science at San Diego State University, became interested in studying edible ants after conducting research in Oaxaca, Mexico, where a variety of insects were readily available in markets. Despite their popularity as a food source in some cultures, there are few studies on the flavor profiles of these creatures. Understanding the flavors of edible ants could help the food industry create new products that utilize these readily available species.
To better understand the flavors of edible ants, Liu and his team analyzed the odor profiles of four species: the chicatana ant, the common black ant, the spiny ant, and the weaver ant. The researchers identified volatile compounds present in each species and matched them to their perceived odors using an olfactometer. Some surprising findings included the discovery of undetectable ant pheromones at high concentrations.
The researchers found that different ant species exhibited unique flavor profiles. For example, common black ants had a sour winey odor due to high formic acid content while chicatana ants had predominant hazelnut woody green odor profile. The researchers also analyzed ants at various developmental stages to understand how flavor profiles changed throughout their life cycle. Despite potential nutritional and environmental benefits of consuming edible insects such as high protein content and low fat levels , people with food allergies especially shellfish need to be cautious when trying these creatures for taste testing purposes only should be done by trained professionals who know about possible allergens before hand.
Liu hopes to continue exploring other ant species’ taste profiles developmental stages and processes that affect flavor production in edible insects while acknowledging challenges such as high prices consumer acceptance he believes that these insects can offer unique delicious flavors for culinary creations by informing people about its health benefits without making them feel like they have compromised on taste or nutrition
