The production of fruit and vegetable in China is massive, and their processing as well as imports and exports have developed rapidly in recent years. But there are some safety problems on processing and trade of imports and exports in fruit and vegetable, including microorganism and its toxin, the residual and added harmful materials during processing, the produced harmful materials during processing, as well as some harm from packing. By standardization of raw material, processing and product, these problems can be solved and the industry of fruit and vegetable can be developed normally.
