Regulatory Authorities:
Whether the color loss is illegal needs to be tested by a professional organization
The reporter consulted the relevant staff of the Nanjing market supervision department on the problem of the fading of sugar oranges.
A staff member of the Nanjing Qinhuai District Market Supervision Bureau said that sugar oranges will use edible wax to maintain moisture, general edible wax will not fade, and the specific discoloration situation cannot be simply determined how it is caused, and further testing is needed.
The relevant staff of the Nanjing Yuhuatai District Market Supervision Bureau told the Modern Express reporter that when orange fruits are generally peeled, slight dyeing will occur on the hands, and if the dyeing is found to be dark or the color is obviously abnormal, it is not excluded that the coloring substance is used.
According to the staff, sugar oranges should be fresh fruits in the "National Standards for Food Safety" (GB 2760-2014), and colorants are not used in fresh fruits. In addition, if colored with non-edible substances, it may cause harm to the human body. However, whether to use coloring substances for coloring and what kind of substances are used is difficult to judge by the naked eye, and it is necessary to test by professional institutions to draw a definite conclusion.
The staff suggested that if consumers have doubts and concerns, they can call 12315 to report to the market supervision department, and the regulatory department will further investigate and verify the situation.
