Multiple brands have been questioned for having trans fatty acids in their products, HeyTea: Not true! Completely in compliance with the national standard of 0 trans fatty acids.

Some evaluations have claimed that there are trans fatty acids in the products of many tea beverage brands, including Xicha. In response to the above situation, Sina Finance inquired with Xicha, who stated that this information is untrue and seriously misleads consumers. "According to the report 'Dietary Intake Level of Trans Fatty Acids and Risk Assessment for Chinese Residents' released by the National Food Safety Risk Assessment Expert Committee, trans fatty acids in food come from natural sources and processed sources, with the average content of trans fatty acids from natural sources in milk and dairy products being 0.83g/100g. This has also led to the phenomenon of trace amounts of trans fatty acids in Xicha products using real milk during testing." Xicha stated that all of their products use high-quality ingredients like real milk, real tea, real fruit, and real sugar, all of which are tested by professional testing agencies and meet relevant standards. Each Xicha product is also sent to professional institutions for testing, with all product lines meeting the requirements of "0 milk essence, 0 flavoring, 0 fruit syrup, 0 vegetable fat powder, 0 hydrogenated vegetable oil, 0 trans fatty acids, 0 instant tea powder."
