這篇後來好像澄清文不多, 所以補一下. 來自EEAS (European External Action Service) 官方文件, 中英對照版如下.

簡單來說
a. 銅葉綠素是常用食品添加劑, 可能自然產生
b. 歐盟僅提出要持續研究銅葉綠素的量化的可行辦法, 包含審查台灣的測試方式; 另外台灣檢驗方式無法驗出"人工添加"銅葉綠素, 已經遭國際橄欖理事會要求台灣停止以此測試方法來做為添加物的依據.

擷取重點:
1.Copper chlorophyll is chlorophyll-derived compound which can be used as a (green) food colorant. It is a commonly used food additive and it is of no health concern.
銅葉綠素是一種葉綠素衍生的化合物，可被用作食品著色劑（綠色）。它是一種常用的食品添加劑，並且沒有健康疑慮。

2. Copper chlorophyll can occur naturally in certain types of edible oil: it is a substance that can be formed during the processing of olive pomace oil and grape seed oil. Consequently, detection of the presence of copper chlorophyll in these types of oil does not mean that it has been added.
銅葉綠素在某些類型的食用油中可以自然產生：它可以在橄欖粕油和葡萄籽油的加工過程中形成。因此，在這些類型的油中檢測到銅葉綠素，並不代表銅葉綠素是被添加至該油品中。

10. The IOC continues to work on a possible method that could quantify the presence of copper chlorophyll in olive pomace oil, including through a collective review of an analytical testing method used by Taiwan's Food and Drug Administration.
國際橄欖理事會持續研究可將橄欖粕油中銅葉綠素量化的可行方法，其中包括集體檢測台灣食品藥物管理署使用的分析測試方法。

11. The IOC requested Taiwan to suspend the use of their analytical method as evidence for determining that copper chlorophyll has been fraudulently added to edible oils, awaiting the outcome of the on-going research referred to above, as this current method is not suitable to detect fraudulently added copper chlorophyll in olive pomace oil.
由於目前台灣採取的檢測方法不適用於偵測橄欖粕油是否含有人工添加銅葉綠素，國際橄欖理事會要求台灣停止以此分析測試方法做為判斷食用油品是否有添加銅葉綠素的依據，並等待國際橄欖理事會研究結果。
