Imported oil products were found to contain copper chlorophyllin. Today (19th), Tai Shan held a joint press conference with its Spanish supplier to protest their innocence, emphasizing there was no oil mixing or adulteration. They claimed that grape seed oil is a natural plant and did not rule out the possibility that copper chlorophyllin could be naturally present or formed during processing. The Ministry of Health and Welfare immediately refuted this, stating that after reviewing international literature, they had never heard of such a claim. They clarified that testing for "copper" and "copper chlorophyllin" are two different matters, and detecting the latter constitutes illegal addition. The domestic testing method is internationally recognized.
Tai Shan Chairman James Zhan held a press conference in the afternoon with Victor, General Manager of the Spanish company Victoria, arguing that the Ministry of Health and Welfare's testing method was "qualitative but not quantitative," only capable of detecting the presence of copper chlorophyllin, which could also occur naturally.
James Zhan stated that after multiple tests, Tai Shan's grape seed oil naturally contained higher levels of copper than olive oil. However, the copper content in Tai Shan's products still met the CNS national standard of below 0.4ppm. He suggested that copper chlorophyllin could have formed during the manufacturing process due to washing, high temperatures, or high pressure, attempting to dispel suspicions of illegal copper chlorophyllin addition.
"Copper and copper chlorophyllin are two different things!" emphasized Shi Yangzhi, head of the Research and Inspection Division at the Food and Drug Administration (FDA). The FDA tests for the pigment "copper chlorophyllin." While the laboratory also tested the "copper" content in Tai Shan's oil, which was indeed below the CNS national standard, this was entirely separate from the issue of illegal "copper chlorophyllin" addition.
Shi Yangzhi explained that the FDA's self-developed testing method uses high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) for "qualitative" analysis. Although it cannot "quantitatively" determine precise levels, it can immediately detect the presence of copper chlorophyllin. This method is internationally recognized and publicly available on the FDA's website, with no objections raised so far.
Could copper chlorophyllin, an artificial additive, naturally occur as residue? Shi Yangzhi, as a scientist, stated that no such claim had been found in international literature. If Tai Shan had a "new discovery," they were welcome to discuss it.
In response to public curiosity about the testing methods, the FDA announced it would open its Kunyang Laboratory to the media at 10 a.m. the next day, showcasing the three instruments used to test for gossypol, fatty acid distribution, and copper chlorophyllin. The FDA also planned to hold a video conference with local health bureaus that evening to establish standard procedures for crude oil sampling and documentation.

Taiwan Copper Green 'Naturally Occurring'? Health Ministry Denies: Unheard of in Global Literature
