散白酒为什么不能用塑料袋装?

一: 用塑料包装不保鲜,而且还会有塑料味:

1: Plastic packaging is not fresh, but also has a plastic smell:
酒保存得好坏与否,不仅直接影响其口感。尤其对收藏者来说,还决定了酒的升值潜力。
The quality of wine preservation not only directly affects its taste. Especially for collectors, it also determines the appreciation potential of wine.
塑料包装由于透明或者半透明,光线中的紫外线对酒的损害也是很大的,也是加速酒氧化过程的罪魁祸首之一,因此,想要长期保存的葡萄酒一定要用深色玻璃瓶或者不透明瓷器。
Because the plastic packaging is transparent or translucent, the ultraviolet ray in the light also causes great damage to the wine, and is also one of the main culprits to accelerate the oxidation process of wine. Therefore, the wine that wants to be preserved for a long time must use dark glass bottles or opaque porcelain.
二:陈酿:
2: Aging:
酒装在瓶中,其变化是一个缓慢的过程,振动会让酒加速成熟,当然结果也是让酒变得粗糙。所以应该放到远离振动的地方,而且不要经常搬动。

When wine is bottled, its change is a slow process. Vibration will accelerate the maturation of wine, and of course, the result will also make the wine rough. So it should be placed away from vibration and not moved frequently.
三: 密封度:
3: Tightness:
已开瓶而未喝完的酒,比较理想的方法是先将酒瓶中的空气抽光,再塞上瓶塞,这样可以保存很长时间,塑料包装不具备密封的要求。
For wine that has been opened but not finished, the ideal method is to pump out the air in the wine bottle first, and then plug the bottle, which can be kept for a long time. Plastic packaging does not meet the requirements of sealing.
四: 塑料包装自身的缺陷:
4: Defects of plastic packaging itself:
塑料包装相对于玻璃瓶装(或者瓷器容器)来说,塑料包装对氧与一氧化碳的渗透系数较大,它会导致其中的酒与塑料包装之间发生化学反应,而且,酒会被氧化而使酒的口味发生劣变。
Compared with glass bottles (or porcelain containers), plastic packaging has a larger permeability coefficient of oxygen and carbon monoxide, which will lead to chemical reaction between the wine and plastic packaging, and the wine will be oxidized and the taste of wine will deteriorate.
塑料包装制品的老化也影响外观质量,不美观实用,且污染环境。
The aging of plastic packaging products also affects the appearance quality, is not beautiful and practical, and pollutes the environment.
可以用塑料桶装。市面上销售的一些低档白酒,比如二锅头,高粱酒等等,都有塑料桶装的。据介绍,目前食品级塑料包装材料主要分成两类:一类是普通PE?聚乙烯塑料,另外一类是PET?聚酯塑料。前者适用于普通食品和饮料,后者适用于酒、食用油等溶解性强的食品和饮料。普通聚乙烯塑料桶用于装白酒,时间一长,聚乙烯可溶解于酒精,人们饮用后,可能会引起皮肤过敏,严重的会导致贫血。PET则是一种新型的高分子聚酯材料,分子结构更加稳定,用于装白酒,不会对人体造成危害,但密封性不如玻璃瓶,存放时间过长后,酒精会逐渐挥发。
It can be packed in plastic drums. Some low-grade Baijiu sold on the market, such as Erguotou, sorghum wine, etc., are packed in plastic barrels. According to experts, at present, food-grade plastic packaging materials are mainly divided into two categories: common PE? Polyethylene plastics, the other is environmentally friendly PET? Polyester plastic. The former is applicable to ordinary foods and beverages, while the latter is applicable to foods and beverages with strong solubility such as wine and edible oil. Ordinary polyethylene plastic barrels are used to hold Baijiu. For a long time, polyethylene can be dissolved in alcohol, which may cause skin allergy and even anemia after people drink it. PET is a new type of high molecular polyester material with more stable molecular structure. It can be used to fill Baijiu without harm to human body, but its sealing is not as good as glass bottles. After being stored for a long time, the alcohol will gradually volatilize.
