Analyzing isotopes for nitrate in sake for combating beverage fraud in Japan - EurekAlert
<p><strong>The demand for sake—a Japanese alcoholic drink—has increased globally. However, the rise in the popularity of sake has the </strong><strong>potential for</strong><strong> related beverage fraud. To address this issue, researchers from Japan identified a novel method to authenticate the source of and differentiate between sake</strong><strong> breweries</strong><strong>. They measured the oxygen and nitrogen stable isotopes in nitrates within sake using denitrifying bacteria</strong><strong> first</strong><strong>. Their findings could help prevent mislabeling of the sake’s brewery of origin. </strong></p>
