Lê, táo để 2 tháng vẫn tươi

Đó là trái cây chưng tết của gia đình chị Sông Ngân ở P.Hiệp Bình Chánh, Q.Thủ Đức (TP.HCM). Theo chị Ngân, những loại trái cây này chị mua trước Tết Nguyên đán 2012.

Sau khi chưng xong, chị không bỏ vào tủ lạnh nhưng đến nay trái cây vẫn tươi nguyên nên gia đình chị không dám ăn.

Trao đổi với chúng tôi về trường hợp này, một cán bộ của Chi cục Bảo vệ thực vật TP.HCM cho biết hiện nay có nhiều phương pháp để giữ trái cây tươi lâu. Trong đó, cách phủ màng sinh học là hữu hiệu và không ảnh hưởng đến sức khỏe người tiêu dùng.

Nếu lê, táo để ngoài môi trường bình thường mà không được bảo quản đúng cách thì chỉ tươi và có thể sử dụng được trong vòng một tuần.

“Trường hợp trên có thể sử dụng chất bảo quản hoặc màng bảo vệ sinh học để giữ trái cây được tươi lâu. Tuy nhiên phải có mẫu cụ thể và qua quá trình xét nghiệm mới đưa ra kết luận chính xác” - vị này nói.
