About ZHII — Cooling Agent & Flavor Manufacturer
ShaanXi ZhiYi Biotechnology Co., Ltd. has spent nearly two decades perfecting high-purity cooling agents, food flavors and plant extracts — exporting to 50+ countries with ISO, KOSHER and HALAL certification.


From a Xi’an Workshop to a Global Cooling Agent Supplier
Founded in 2007 in Xi’an — the historic gateway of the Silk Road — ShaanXi ZhiYi Biotechnology Co., Ltd. built its brand ZHII around one mission: delivering flavor and fragrance ingredients that meet international standards at competitive factory pricing.
Over 18 years we have grown from a regional flavor house into a comprehensive biotechnology enterprise integrating R&D, production and export sales. Our specialization in the WS-series cooling agents (WS-23, WS-3, WS-5, WS-10, WS-11, WS-12, WS-27, WS-1, WS-2) and L-menthol crystals now reaches food, beverage, confectionery, oral-care, cosmetic and flavor concentrate manufacturers across 50+ countries.
Every order is backed by a Certificate of Analysis, full export documentation and an English-speaking team that quotes within 24 hours. That consistency is why buyers in the EU and Americas keep coming back.
