Do you know that beer bottles are mostly green?
[China Glass Network] Although it has entered the autumn, the weather is still not very cool. Many people are still waiting for the summer heat, and they will grab the beer and drink beer. However, I wonder if you have noticed that most of the beer bottles we have seen are green. Although they are also brown, blue or even colorless, they are mostly green bottles. So why is the beer bottle green? Using green beer bottles is traditional Although the history of beer is very long, the time to put beer in glass bottles is not too long, starting from the mid-19th century. At the beginning, people even thought that glass was green. At that time, not only beer bottles, ink bottles, paste bottles, and even window glass were slightly green. Dr. Cao Chengyu from the Institute of Physics of the Chinese Academy of Sciences told the Science and Technology Daily: "This is because when the process of making glass is not very sophisticated, it is difficult to remove the impurity ions such as ferrous ions in the raw materials, so the glass produced is Show green." Later, the glass manufacturing process was advanced, and these impurities could be removed, but the cost was too high, and it was not worth the effort to use the glass as a non-precision instrument. Moreover, it was found that the green bottle can delay the beer to taste, so the people produced green in the late 19th century. The glass bottle was used to carry beer, and the tradition of green beer bottles was preserved. "Later, people will add ferrous oxide and chromium oxide to the glass as a coloring agent to make it look greener." Cao Chengyu said. Recapture Jiangshan from the brown bottle In the 1930s, people accidentally discovered that the beer contained in the brown bottle did not deteriorate after a long time. “This is because the brown bottle of beer can avoid the influence of light on beer.†Cao Chengyu said. Beer under the sun will produce an odor. The study found that the main culprit in the production of odor is isoalpha acid in hops. Under the light conditions, the bitter component of hops in hops will help the formation of riboflavin. At the same time, the isoalphaic acid in beer will react with riboflavin to decompose into a compound. The taste of this compound is like the fart released by the weasel. . The use of brown bottles or some dark bottles can absorb most of the light, which can hinder this reaction. So, the beer that used brown bottles later became more. However, after World War II, European brown bottles were in short supply, and some of the more famous beer brands had to re-use green bottles to load beer. Because of the good quality of these brands of beer, green beer has become synonymous with high-quality beer. Then many beer manufacturers followed suit and used green bottles. "At this time, with the popularity of refrigerators and the advancement of sealing technology, the use of brown bottles will not bring better quality than the use of other colors of the bottle." Cao Chengyu said. Therefore, the green beer bottle has prospered. Bikini Tops,Cute Bikini Tops,Cheap Bikini Tops,Womens Bikini Tops Shaoxing Concord Textile Co., Ltd. , https://www.ctknites.com
