Just after the national day, some tourists went to Shanxi to take the specialty old vinegar of Pingyao ancient city of Shanxi, but the reporter found it was fake. The most famous thing in Shanxi is old vinegar. This time, it's a shame to lose your hair. So how to identify the real and fake old vinegar? Let's learn.
How to distinguish true and false vinegar
1. Look at trademarks
As for vinegar, the vinegar produced by regular manufacturers will have its acid content. You can look at Shanxi's old vinegar and find out the trademark and logo of the vinegar.
2. Look at the date
The production date of vinegar must also appear on the packaging of vinegar. We all need to know that in general, the validity period of vinegar must be presented. And it is recommended that you choose whether it is brewed or compounded according to your personal taste.
3. Look at the manufacturer
Good real vinegar needs manufacturers. Now there are many small shops selling vinegar without the manufacturer's logo. If you encounter it, you are advised not to buy it.
4. Look at the color
General good vinegar, its color is red brown color or amber color. And if you buy vinegar with strong color, it's bad vinegar. Generally, pour vinegar, and you can see the color.
5. Look at form
For vinegar, it is a kind of continuous flowing liquid, so when choosing, you can see if it is clear, there is no sediment at the bottom, etc., and if there is sediment, it is a good vinegar. Of course, there should be no floating objects.
6. Smell it
Vinegar is fragrant and has a special sour taste. Some people can know the quality of vinegar by smelling it. If vinegar has a heavy chemical smell, it is not recommended to buy.
What do you think of mixed vinegar
1. Buying vinegar and looking at the label is an effective way to distinguish brewing vinegar from compounding vinegar: for pure grain brewing vinegar, the words "brewing vinegar" are written on the product label, while compounding vinegar must be marked as "compounding vinegar", otherwise it is commercial fraud.
2. According to the national standard, the total acid of brewing vinegar shall not be less than 3.5 degrees (the total acid content per 100ml is 3.5G), and it shall meet the national standards gb18187 and gb19777. Therefore, it can also be distinguished according to the total acid content on the label and whether there is any one of the product standard numbers.
3. If the word "acetic acid" or "glacial acetic acid" is written in the additive, it can only be called "preparation of vinegar", otherwise it is a violation.
If you are going to a tourist attraction, please also buy products with trademarks. If you are making vinegar from your own home, you can buy the old brand and the old shop.
