Experiment: PP material selection boxes thermal stability good reporter a few shops for high temperature food lunch boxes, just after one by one into the boiling water, most of the box to knead up some a little soft, but did not smell any peculiar smell.
Subsequently, the reporter from four different shops with a disposable plastic lunch box, material to suzhou city comprehensive testing center of quality inspection department, of an engineer there, please check.
Inspectors respectively using n-hexane and water (
A colorless liquid)
And analog neutral food and greasy food, thermal stability and evaporation residue detection of disposable plastic lunch boxes.
According to introducing, evaporation residue refers to food contact materials, simulated oil after soaking in water, then soak liquid dry out of the proceeds of the all is not the amount of volatile substances.
Residue into the human body adverse impact on health, will also directly affect food color, aroma, taste, etc.
Testing personnel with 60 ℃, 80 ℃ and 95 ℃ hot water, soak journalist sample plastic tableware for 2 hours, the results found that thermal stability is good, the tableware stripping residue were no obvious change;
With 40 ℃ n-hexane imitate soaking greasy food tableware after two hours, detected from the soaking liquid residue are within the scope of the standard limit.
Suzhou comprehensive testing center of quality material inspection department minister li-xia liu, currently on the market the use of disposable plastic tableware materials mostly & other;
, the reporter makes tableware is PP material.
This kind of flexible material itself is good, do not need to use a large number of plasticizer in the production process to make its forming, is relatively high safety material.
With the increase of temperature, PP material of plastic cutlery in acid medium water and thermal stability is generally good, the highest heat temperature up to 130 ℃.
And other like PET -
Material of heat-resisting temperature is only about 70 ℃, is only suitable for used for holding the cold.
So, if you want to use plastic boxes with hot porridge hot food, such as, no oil liquid, and suggest people choose PP material products as much as possible.
Li-xia liu, prior to this, city quality comprehensive testing center who accepts the commission of the jiangsu province department of quality control, 45 batches for sales on the market use plastic bowl is used to detect the quality safety risk, most of these samples for PP material.
In the risk monitoring, detection researchers found, is about 20 ℃ with n-hexane immerse evaporation residue experiments again after two hours, as a result, more than thirty percent of the samples failed to pass.
This means that the plastic bowl when in direct contact with grease food easy to dissolve the residue, the more residue and dissolution, the higher the risk of use, the more can bring adverse effect to health.
The reporter sees in the risk monitoring report, & other
Disposable plastic tableware if a large amount of calcium carbonate is added in the production of raw materials, talcum powder, industrial paraffin wax, recycling waste, etc. , it is easy to cause excess evaporation residue of products.
The minerals and additives such as oil and food contains substances such as easy to dissolve each other, with the food enters the body, may cause indigestion, local pain and liver disorder, serious still can cause gallstones, heavy metal poisoning, and even cancer, etc.
Fujian xing suggested, therefore, people should be careful when packaged food disposable plastic lunch box, especially oily larger and higher temperature packaging food, had better choose other safer tableware.
