What Is Star Anise? The True Nature of a Spice Vietnam Takes Pride In<\/h2>\n

That spice with the distinctive sweet aroma, written with the characters for 'eight corners.'
\nWith its striking star-shaped fruit, it is familiar from Chinese cuisine and Taiwanese sweets.<\/p>\n

In fact, about 80-90% of the world's star anise supply is produced in just two countries, Vietnam and China.
\nAnd as an indispensable raw material in both the pharmaceutical and food sectors, it is increasing its presence in the international market.<\/p>\n

'Why is star anise drawing attention now?' 'What are the characteristics of the Vietnamese kind?'
\nThis article explains it all, from the realities of the growing regions to world demand and its medicinal and culinary uses.<\/p>\n

Lang Son Province Is the Hub: Vietnam's Largest Star Anise Production Area<\/h2>\n

The center of star anise production in Vietnam is the northern Lang Son province<\/strong> of organic jasmine rice.
\nThis region, which borders China's Guangxi, has a mountainous, cool climate well suited to growing star anise.<\/p>\n

On the farmland spread across mountainous terrain at an elevation of 400 to 1,000 m, Illicium verum trees, which grow 5 to 15 m tall, are planted in rows.
\nThe trees bear their first harvest five to six years after planting, and may continue to bear fruit for nearly 100 years thereafter.<\/p>\n

Besides Lang Son province, cultivation is also carried out in Cao Bang and Bac Kan provinces.
\nHowever, Lang Son province stands out in both volume and quality, and 'Lang Son origin' is recognized as a brand.<\/p>\n

Vietnam's Annual Production<\/h3>\n

Vietnam's star anise production varies by year, but in recent years it has hovered around 10,000 to 15,000 tonnes.<\/strong> It has stayed at that level.
\nA large share of this is exported as dried product, with Japan, the EU and the United States among the main destinations.<\/p>\n

The Structure of Global Share: A Vietnam-China Duopoly<\/h2>\n

The international market for star anise is almost monopolized by Vietnam and China.
\nThe shares of the main producing countries are summarized below.<\/p>\n\n\n\n\n\n\n\n
Country<\/th>\nEstimated Share<\/th>\nMain origins<\/th>\n<\/tr>\n<\/thead>\n
China<\/td>\nAbout 50-60%<\/td>\nGuangxi, Yunnan<\/td>\n<\/tr>\n
Vietnam<\/td>\nAbout 30-40%<\/td>\nLang Son, Cao Bang<\/td>\n<\/tr>\n
Others (Laos, etc.)<\/td>\nA few %<\/td>\nthe northern mountains<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Chinese production is larger in absolute terms, but in recent years rising labor costs and the aging of its growing regions have become challenges.
\nVietnamese product, meanwhile, is highly rated for its consistent quality and price competitiveness, and its export volume is steadily growing.<\/p>\n

The shift by EU and Japanese food manufacturers toward Vietnamese product is especially notable, and it is drawing attention from the standpoint of diversifying sourcing.<\/p>\n

As a Raw Material for Tamiflu: Its Little-Known Medicinal Demand<\/h2>\n

Star anise came into the spotlight in the pharmaceutical field in the early 2000s.
\nAs a key raw material for the anti-influenza drug 'Tamiflu (oseltamivir)<\/strong>', its importance surged all at once.<\/p>\n

To synthesize oseltamivir phosphate, the active ingredient in Tamiflu, the shikimic acid<\/strong> contained in star anise is used.
\nShikimic acid is extracted from the fruit of star anise and, through several chemical reactions, becomes Tamiflu.<\/p>\n

How Tamiflu Demand Caused Star Anise Prices to Surge<\/h3>\n

During the 2005-2006 avian influenza outbreak, governments around the world tried to stockpile large quantities of Tamiflu.
\nAs a result, demand for star anise surged, and prices temporarily jumped several to more than ten times their level.<\/strong> Such a situation occurred.<\/p>\n

Afterward, an alternative synthetic route for shikimic acid was also developed for Tamiflu's manufacturing process, but star-anise-derived shikimic acid is still one of the main sources of supply.
\nFrom the standpoint of pandemic preparedness, pharmaceutical companies in various countries place importance on building relationships with star anise growing regions.<\/p>\n

Biochemical Uses Beyond Pharmaceuticals<\/h3>\n

Beyond antiviral drugs, shikimic acid is also attracting attention in research on anticancer and anti-inflammatory drugs.
\nThe essential-oil component anethole has also been reported to have antibacterial and antifungal effects.<\/p>\n

Culinary Uses: From Chinese Food to Japanese Cuisine and Western Confectionery<\/h2>\n

Medicinal demand tends to get the attention, but star anise's culinary uses are overwhelmingly broader.<\/p>\n

Worldwide, star anise is used in settings such as the following.<\/p>\n\n\n\n\n\n\n\n\n\n
Use Category<\/th>\nExamples<\/th>\n<\/tr>\n<\/thead>\n
Chinese cuisine<\/td>\nfive-spice powder, braised pork belly, lu rou fan<\/td>\n<\/tr>\n
Vietnamese cuisine<\/td>\nthe soup stock of pho<\/td>\n<\/tr>\n
Western confectionery and liqueurs<\/td>\nabsinthe, pastis, mulled wine<\/td>\n<\/tr>\n
Indian cuisine<\/td>\nbiryani, masala chai<\/td>\n<\/tr>\n
Japanese processed foods<\/td>\nramen soup, sauces, prepared side dishes<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

It is an indispensable spice for Vietnamese pho in particular, so much so that people say 'pho without star anise is not pho.'
\nJust adding a few pieces while simmering the pho broth produces that distinctive sweet aroma.<\/p>\n

In Japan, too, it has long been familiar as a Chinese cooking ingredient, but in recent years demand has grown as a flavoring for craft gin and craft beer.<\/p>\n

The Quality and Distribution of Vietnamese Star Anise<\/h2>\n

Vietnamese star anise is distributed in four forms: whole dried fruit, broken, powder, and essential oil.<\/p>\n

The main indicators of quality are as follows.<\/p>\n
