Pros and cons of plastic barrels of liquor
According to the survey Taitung district a supermarket, liquor counters that many spirits are dressed with a plastic bucket. These plastic bottles or plastic bucket different colors, sizes vary, some containing 500 ml, some with a capacity of 5 liters.
Then the staff came near several shopping centers, found that almost every family has a similar liquor sales. One is to buy this plastic drums liquor people say, plastic barrels of liquor, compared with the price of glass bottles, a lot cheaper, but the taste is similar, so why would it spend money on packaging costs.
In addition to a large number of supermarket plastic barrels of liquor sales, the reporter in some small bulk wine shop also found a lot of small plastic bucket used to hold wine.
So plasticizer is how to enter the wine from plastic in it? Staff linked to this professor surnamed Qiao Institute of Chemical Technology, Dalian University of Technology, he said, adding the plastic manufacturing process plasticizing agent may increase the ductility, but the plasticizing agent and the plastic components are not chemically bonded, and therefore When it will continue to be encountered in organic solvents extracted.
It is understood that plasticizers commonly found in PVC plastic wrap, plastic bags, plastic buckets, raincoats, toys among these plastic products in contact with the oil, wine and other solutions, plasticizers can continue to precipitate thus been eating from plastic products into, but the higher the temperature, the faster the deposition rate, the amount of elution at 80 ℃ 14 times when 60 ℃. There are people who often use plastic bags to pack soup, not only heat, but too oily soup ingredients, plasticizers are also more precipitation.
Because of plasticizing agents can quickly precipitate in solution, such as wine and oil, and it is best not to use plastic containers to pack wine and oil, and the deposition rate of plasticizer associated with alcohol concentration, the higher the alcohol concentration, the faster precipitation . If you have installed, then the best choice for polyethylene terephthalate plastics, which is in the bottom or the bottle has a triangular logo, which has the number "1" plastic barrels, the state for this kind of food-grade packaging production has stringent requirements, citizens do not have to worry.
It is understood that the general and PET Heat to 70 ℃ deformation, can not hold hot liquids or heat, and do not place in sunlight, otherwise it will break out of small molecules of harmful substances. Liquor best stored in a cool, well-ventilated place, after the consumption of liquor should be opened as soon as possible, to avoid the ingredients that become unstable and react with other ingredients.
