FOR IMMEDIATE RELEASE
In the U.S., we’re deep in the winter season � a time when many people get sick and feel “under the weather.� To feel better, some people drink antioxidant-containing beverages, such as beetroot juice or elderflower teas, while others might sip whiskey or splash it into hot toddies. Below are recent papers published in ACS journals that report insights into compounds that contribute to the health benefits and aromas of these beverages. Reporters can request free access to these papers by emailing newsroom@acs.org.

The red beet’s bright, vibrant color comes from phenolic compounds and betalains, which also possess antioxidant properties. When these root vegetables are juiced, the resulting drink can have an unpleasant soil-like smell. Previously, heat treatments helped make it smell more palatable, but they reduced the healthful properties. This research team showed that treating beetroot juice with electricity, specifically electro-activation by an anode, produced a more stable juice while maintaining its color and enhancing its antioxidant activity.

Pouring whiskey into a glass releases its scent into the air, which contributes to the flavor of the liquor. Here, a team developed an approach using microbubbles to trap these volatile compounds � a process called fizzy extraction � and then identified them by mass spectrometry. They tested the technique and quickly analyzed 40 whiskeys from distilleries around the world, finding that ethyl propionate and ethyl butanoate could help determine a bottle’s overall quality.

Most commercial elderberry flower teas and syrups are made from European plants. But the blue elderberry, a subspecies native to western North America, is starting to be considered for similar drinks. Now, for the first time, researchers have identified the blue elderberry flower’s scent and phenolic compounds. These compounds could be used to make products with unique aromas and different antioxidant compositions compared to products made with European elderflowers, the researchers say.
