现实生活中，我们买东西都会习惯性的看生产日期和保质期，无论是商品还是食品，觉得只要是在保质期内就可以放心使用。
In real life, we habitually check the production date and expiration date when buying things, whether they are goods or food, thinking that as long as they are within the expiration date, they can be used with peace of mind.
但是你知道吗？其实有些商品的保质期只是因为国家有规定，并不是说超过保质期就不能够再用了。比如以下这7样东西，有专家说，即使过期了也内事，大家不要再傻傻的丢掉了，赶紧来看看吧。
But do you know? In fact, the expiration date of some goods is just because of national regulations, not that they cannot be used anymore after the expiration date. For example, the following 7 items, experts say, are still usable even if expired, and everyone should no longer foolishly throw them away. Let’s quickly check them out.
01、蜂蜜几乎不会过时 01、Honey almost never goes bad
我们在超市购买的蜂蜜都会标注有生产日期和保质期，其实一般蜂蜜是不会变质的，而之所以要标上保质期，主要也是因为要符合相应的规定才能够售卖。
The honey we buy from supermarkets is usually labeled with a production date and expiration date. In fact, honey generally does not spoil, and the reason for labeling an expiration date is mainly to comply with the relevant regulations in order to be sold.
因为蜂蜜当中天然的酸性和低水分含量可以抑制霉菌的生长，所以即使蜂蜜放了很长一段时间，通常也是安全的。
Because the natural acidity and low moisture content in honey can inhibit the growth of mold, even if honey has been stored for a long time, it is usually still safe.
不过，一般蜂蜜放久了就会出现结晶或者变色，这种情况主要是因为糖分发生了变化，但并不意味它坏了。
However, honey that has been stored for a long time may crystallize or change color, which is mainly due to changes in the sugar content, but it doesn’t mean it has gone bad.
另外，有的人习惯性的将蜂蜜放在冰箱里面储存，这样储存就会导致蜂蜜结晶，从而影响到它的质量和口感，最好的方式就是密封好放在阴凉干燥的位置，一般情况下是不会变质的。
Additionally, some people are accustomed to storing honey in the refrigerator, which can cause the honey to crystallize and thus affect its quality and taste. The best way is to store it in an airtight container in a cool, dry place, as it generally will not spoil.
02、香水没有固定保质期 02, Perfume has no fixed expiration date
一般国内专柜的香水都会标明生产日期，使用期限等等，而且一般保质期是五年时间，但是在国外就没有这样的明确要求，他们不会给香水标上保质期，但是可以查询到香水的生产日期。
Generally, perfumes in domestic specialty stores in China are labeled with production dates and expiration dates, and the shelf life is usually five years. However, in foreign countries, there are no such clear requirements; they do not label perfumes with an expiration date, but the production date can be checked.
因为香水的成分主要是由香料加酒精溶剂组合而成，也就是说，香水里面的酒精成分是比较多的，而密封状态下的酒精本身就不会过期，所以一般来说，只要香水处于密封状态，就不存在过期一说。
This is because the main components of perfume are fragrances mixed with alcohol solvents. In other words, the alcohol content in perfume is relatively high, and alcohol itself does not expire when kept sealed. Therefore, generally speaking, as long as the perfume remains sealed, there is no concept of expiration.
当然，虽然香水没有固定的保质期，但是部分香水的瓶身也会印有“开封后推荐几个月内用完”的字样，
Of course, although perfume doesn’t have a fixed expiration date, some perfume bottles also print “Recommended to use within a few months after opening” on them
因为开封的香水接触到空气之后，就会慢慢的香味变淡，容易挥发，如果保存不合理的话，就可能会出现变质，所以商家才会瓶身标上推荐多久使用完。
Because opened perfume gradually loses its scent when exposed to air, it is easily volatile. If stored improperly, it may spoil, which is why retailers mark the bottle with a recommended usage period.
另外，存放香水时，最好避免高温和阳光直射，这样才能延长香水的使用寿命，而且如果香水出现气味变得刺鼻或者颜色变深，那么这种香水建议不要继续使用了。
Additionally, when storing perfume, it is best to avoid high temperatures and direct sunlight to extend its shelf life. Moreover, if the perfume develops a pungent odor or darkens in color, it is advised not to continue using it.
03、白酒还是陈的香 03, Baijiu is more fragrant when aged.
想必这句话很多人都听说过，白酒还是陈的香，因为一般来说，白酒只要储存的时间越久，价格就会更贵，因为长期的储存会让酒的口感更加醇厚，协调香气也更加浓郁。
I’m sure many people have heard this saying, “Aged baijiu is more fragrant,” because generally speaking, the longer baijiu is stored, the higher its price will be, as long-term storage makes the taste of the wine richer and the aroma more harmonious and intense.
就拿酱香型白酒茅台酒来说吧，储存的时间越长，它的口感和品质就会得到显著提升，而且年份越久的茅台酒在市场上的价值也更高，这样的酒甚至可以永久储存，没有保质期。
Take the Maotai baijiu, a Jiangxiang-style baijiu, for example. The longer it is stored, the more significant the improvement in its taste and quality, and the higher its market value becomes. Such wine can even be stored indefinitely, with no expiration date.
但如果是那些低度白酒，长时间储存，可能就会导致酒的品质下降，出现水解现象，比如九位变淡，香气减弱等等，这种白酒储存的时间越长，反而市场价值会越低。
However, for low-proof baijiu, long-term storage may lead to a decline in quality, such as hydrolysis, where the color may fade and the aroma weakens. For this type of baijiu, the longer it is stored, the lower its market value becomes.
04、食用盐永不过期 04. Edible salt never expires
其实咱们平时买的食用盐的包装袋上都有保质期，一般都是五年，但是这并不意味着过了五年之后食盐就不能用了。
Actually, the packaging bags of edible salt we buy usually have a shelf life, which is generally five years, but this doesn’t mean that the salt can’t be used after five years.
食用盐的主要成分就是氯化钠，含有天然的防腐抗菌作用，所以食用盐本身就不会过期。
The main component of edible salt is sodium chloride, which has natural preservative and antibacterial properties, so edible salt itself does not expire.
但是，如果购买的加碘盐，在长期光照或者是风吹受热的情况下，这种食用盐就可能会发生一些改变。要注意一下食用盐的保存方法。
However, if iodized salt is purchased, under long-term exposure to light or wind and heat, this edible salt may undergo some changes. It’s important to pay attention to the storage method of edible salt.
比如保存不当的话，可能会出现结块的情况，影响使用效果，所以为了保持质量，建议尽量将食用盐放置在加盖不透明的密封容器当中，远离灶台，避免高温，这样存放时间会更久一些。
For example, if stored improperly, it may clump together, affecting its use, so to maintain quality, it is recommended to store edible salt in a covered, opaque, airtight container, away from the stove, avoiding high temperatures, so that it can be stored for a longer time.
05、面粉过了保质期也能用 05、Flour can still be used even after the expiration date
一般购买的面粉外包装袋上都有生产日期和保质期，而且很多人都遇到过这样的情况，如果购买的是大袋面粉，可能还没有用完，就已经超过了包装上的保质期，那么这种情况真的要浪费丢掉吗？
When buying flour, the outer packaging bag usually has a production date and expiration date. Many people have encountered this situation: if you buy a large bag of flour, you might not have finished using it before it expires according to the packaging. So, do you really have to waste it and throw it away?
其实正常来说，只要面粉保存的好，即使超过了包装上的保质期，在没有出现受潮或生虫的情况下，也是可以正常食用的。
Actually, as long as the flour is stored properly, even if it exceeds the expiration date on the packaging, it can still be used normally as long as it hasn’t become damp or infested with pests.
而且一般来说，常温下的面粉保质期大概在3-12个月，如果面粉没有开封或者是采取的真空保存的话，保质期的时间就会更长一些，所以超过保质期也是能正常吃的。
Generally speaking, the shelf life of flour at room temperature is about 3-12 months. If the flour is unopened or vacuum-sealed, the shelf life will be longer. So, it can still be eaten normally even after the expiration date.
05、食用醋没有过期一说 05. Eating vinegar doesn’t have an expiration date
我们购买的食用醋瓶身都是会有标注保质期和生产日期的，而且基本上保质期都是两年。
The bottles of vinegar we purchase are all labeled with an expiration date and production date, and the expiration period is basically two years.
但是按照相关的规定，酸度达到4.5以上的老陈醋是可以免标保质期的，所以大家在购买陈醋的时候可以注意一下陈醋本身的酸度。
However, according to relevant regulations, old Chen vinegar with an acidity of 4.5 or higher is exempt from expiration date labeling, so when purchasing old vinegar, it’s worth noting the acidity of the vinegar itself.
因为食用醋本身就是纯粮食酿造，而且醋的制作过程是通过发酵而成的，所以它本身就含有一定的天然防腐成分，不容易被细菌等微生物污染，所以不容易出现变质的情况，因此，城步保存得当的情况下是可以存放很久的。
Because edible vinegar is made from pure grain brewing, and the vinegar-making process is through fermentation, it naturally contains certain natural preservatives and is not easily contaminated by bacteria or other microorganisms, so it is less likely to spoil. Therefore, if stored properly, it can last for a long time.
我如果是市面上勾兑的醋，那么情况就不一样了，这种勾兑醋就最好按照说明的保质期来使用，所以，买醋的时候还是要看清楚是哪一种醋。
If it’s a mixed vinegar on the market, the situation is different. Such mixed vinegar is best used within the expiration period indicated on the label. So when buying vinegar, it’s still important to check what kind of vinegar it is.
06、固体糖没有保质期限制 06、Solid sugar has no expiration date
平时我们购买的冰糖等固体糖也是会标注生产日期和保质期，如果过期了，并不是说它就不能够再用了，一般情况下固体糖过期也是能够正常使用的。
The solid sugar we usually buy, such as rock sugar, is also labeled with a production date and expiration date. If it expires, it doesn’t mean it can no longer be used. Generally, expired solid sugar can still be used normally.
因为固体糖的含水量是特别低的，而且渗透压强，不利于微生物生长，所以这种糖长期保存，一般都不会出现变质的情况。
This is because solid sugar has a very low moisture content and high osmotic pressure, which is not conducive to microbial growth. Therefore, when stored for a long time, this type of sugar usually does not spoil.
我如果存放的过程当中，固体糖出现了融化、颜色变黑的情况，那么就说明这个固体糖的性质已经发生了改变，就很容易被微生物污染，这种就不要再吃了，所以存放的时候一定要注意。
If, during storage, the solid sugar melts or turns black in color, it means that the nature of the solid sugar has changed, making it more susceptible to microbial contamination. In this case, it should not be consumed anymore. Therefore, it is important to pay attention when storing it.
写在文末： Written at the end:
有一些物品在超过保质期之后也是能够正常使用的，而这些都是由这些物品本身的特性所决定的，当然大家也要注意其保存的方法哦！
Some items can still be used normally even after their expiration date, and this is determined by the inherent characteristics of these items. Of course, everyone should also pay attention to their storage methods!
