Trong chè xanh của Trung Quốc người ta phát hiện nhiều chất có khả năng gây ung thư. Ảnh minh họa.

Theo các nhà nghiên cứu, chè của Trung Quốc có chứa những chất rất nguy hiểm, đặc biệt các chất độc đặc hiệu đối với một số chủng tộc, nhất là chủng châu Âu (Europeids).


Trước hết, người ta nhấn mạnh đến chất gây ung thư nghiêm trọng là dioctylphtalat (viết tắt DEHP), thuộc họ phtalat, các muối và este của axit phtalic. Trước đây, chất này được dùng như dung môi cho các chất có mùi thơm trong sản xuất đồ chơi và các dồ dùng sinh hoạt cho trẻ em, làm vẻ thẩm mỹ (bóng, đẹp) của sản phẩm tăng lên.



Người ta còn phát hiện ra một chất gây ung thư khác dùng làm phụ gia thực phẩm có mùi thơm của ổi (guava) do công ty Guangzhou Meiyi Flavors&Flagrances sản xuất, có trong chè (dạng bột) và các loại dầu ăn của công ty Jiangmen Gaudy's Food, trong men bánh mì của công ty Jiangmen Jhan Wang Food. Cả ba công ty này đều đóng tại tỉnh Quảng Đông.



Ngoài ra, người ta còn phát hiện chất phụ gia rất nguy hiểm đối với sức khoẻ trong hương liệu ướp chè, trong chè xanh thành phẩm và chất tạo mùi hạnh nhân của công ty Isian tại thành phố Hàng Châu, tỉnh Chiết Giang.



Tháng 5 vừa  qua, Đài Loan đã thủ tiêu 286 tấn thực phẩm chế biến nhập từ Trung Quốc, có chứa dioctyl phtalat. Ngược lại, chính nhà cầm quyền Bắc Kinh vào tháng đó cũng ra lệnh cấm nhập khẩu 948 tấn thực phẩm chế biến của Đài Loan, nói rằng các sản phẩm này chứa các chất độc hại theo quy định của Trung Quốc. Trong khi đó, được biết các sản phẩm chứa DEHP gần đây được phát hiện tại 3 nhà máy tại phía Nam và phía Đông của Trung Hoa lục địa.
