Lang Son star anise is popular not only for its unique aroma but also as a specialty spice. In 2007, Vietnam’s National Office of Intellectual Property officially recognized its geographical indication. In 2020, it gained geographical indication protection in the European Union. By 2022, they initiated a plan to register geographical indication protection for Vietnam’s star aniseed in Japan.
Vietnam star anise is distinctive with a high essential oil content (over 11%) and trans-anethol levels exceeding 90%. Despite of the name “star anise,” it is actually a fruit. Its flower-like shape gives it the familiar name. Actually, the fruit turns from green to dark brown as it matures.
Star anise trees produce fruit twice yearly, with harvesting occurring in July and September. A tree must be at least five years old to bear fruit, making this a rare and valuable spice. Lang Son star anise is a vital ingredient in gastronomy, medicine, and perfumery for its unique aroma and flavor.
Lang Son boasts the largest star aniseed cultivation area in Vietnam. It has more than over 35,000 hectares, which accounts for 70% of the country’s supply. In 2012, they issued geographical indication protection for star aniseed planting in Lang Son province. Under the EU-Vietnam Free Trade Agreement (EVFTA), star anise from Lang Son was recognized in the EU’s list of protection. To meet European standards, the product must comply with stringent quality and technical requirements.
Lang Son province has adjusted its geographical indication management system to align with European regulations. It emphasizes traceability and quality control to ensure the product meets international standards. Training programs have aim to help farmers adopt clean, sustainable cultivation and processing methods.
Therefore, Lang Son star anise has gained international acclaim, boosting local farmers’ incomes. With efforts to secure geographical indication protection in Japan, Vietnamese star anise is expected to continue thriving in high-potential markets, spreading its unique aroma worldwide.
