It may not be safe that the food of nanometer is fashionable The expert claims the food is well in nature
The false pearl powder incident lets consumers know a word for the previous period " The pearl powder of nanometer " ,And pay attention to the market to find, food having relationships with nanometer is really much, I wonder when to get up, nanometer becomes the pronoun helping nutrition to digest and assimilate in food trade. But the spokesman of Hong Kong food security centre said a few days ago, had just carried on the risk assessment about food of nanometer, the result reveals that unable to confirm food of nanometer more traditional food security or dangerous, product that advise supplier should guarantee to sell the food are support eating safely.
The popularization with a word of nanometer, various and nanometer appear to put up the products in the side too in the food industry. The nanotechnology applied to on the food now mainly has several respects: Pack things and membrane in the food and add the nanometer particle, in order to improve the characteristic of the packing materials; With carrier parcel food batching of nanometer and food additive; Process and prepare the batching of food, make the batching become nanometer structure. But it is reported, have internationally acknowledged nanotechnology define, mean in the intersection of atom and grade and control the intersection of material and technology that employ under course of size and shape at the the intersection of molecule and grade usually at present, generally involve at least a size ranges from about 1 to 100 nanometers of structure among them.
On net one the intersection of nanometer and recommendation of wine call oneself, except wine this have general blood circulation promoting silt function of Chinese liquor, also promote the blood circulation, expand the blood vessel, improve function of circulating a little etc., especially beneficial to middle-aged and elderly people's health care, worth giving a recommendation. And washing network sales fields such as the treasure,etc. can see, there are really many relevant products in food, especially nutriment of nanometer. Input in washing the treasure " The pearl powder of nanometer " There are 1353 relevant products, and " nanometer calcium " Also there are 162 relevant chaining. One washes 300g bottled nanometer calcium price of 300 yuan that the seller in Zhuhai of treasure sold, declare because of the application of nanotechnology at the same time, compare with other calcium tablets " Obviously promote and totally absorb fast " .
But such a statement is denied by the Hong Kong food security centre. The spokesmans of this centre say, accurate detection and relevant characteristic of nanometer material have not been established yet in the current food, about employing characteristics of nanometer to be unable to verify frequently, must rely on food industry, the manufacturer and materials that the market sales organization offered.
It is reported, according to the analysis result, because the characteristic of the nanometer material is changed greatly, the security of the food of nanometer can't be treated as the same. Effective evidence does not prove the derivatized food of nanotechnology or food contacts materials relatively the tradition corresponds to the food or material safe or dangerous at present, have not found either that there is an example that proves that it will diminish human health to eat the nanometer material. So product that the Hong Kong food security centre advises supplier should guarantee to sell the food are support eating safely, don't sell the nanometer material that does not undergo to be assessed safely, but the public should keep the balanced diet, and purchase the food from reliable food supplier.
But the expert thinks, the food of nanometer is propagandized by the concept. There are food project experts to say, there is not a national standard of food of nanometer yet at present. Should prove it is the derivatized food of nanotechnology, the trade company must rely on the experimental data, but the relevant experiment is expensive and difficult done, few trade companies do. "Nanometer is only the long measure, and nothing magical. " The expert proposes, the food is good in nature. The intersection of reporter and dawn tip Wu
