1. Observe the color of oyster sauce. The first thing is to look at the bottom of the bottle! Turn the oyster sauce upside down and look at the color of the bottom of the bottle. If the color is black or dark, the quality is definitely not that good. Generally, oyster sauce with really good quality is thin and mushy, without slag particles and impurities, and its color is reddish brown to brown. If you see this, you can buy it with confidence.
2. Look at the oyster sauce ingredient list. The main ingredient in the real oyster sauce ingredient list will be "oyster sauce". Oyster sauce is made from oysters by boiling, concentrating and adding auxiliary materials. Therefore, the word oyster sauce here is the real oyster sauce. Without this ingredient, it is not real oyster sauce, and it is probably artificially prepared.
3. See if oyster sauce will hang on the wall. Pick up the bottle and shake it back and forth a few times. If the oyster sauce will stick to the bottle and flow down slowly, you can buy it. The normal feeling is that it will be thick or thin. If you are particularly thin, you don't have to consider it directly. It must be fake!
4. If the online shopping consumes oil, the most basic thing is to have transportation insurance, so the received goods can be returned no matter what the problem is, which is very convenient. Secondly, you can look at the product label of oyster sauce. If you start with the letter GB, GB is the abbreviation of national standard. If there are these two letters, it means that oyster sauce is produced according to the national production requirements, and everyone can rest assured to eat it.
The above is my answer to the question of how to distinguish the fuel consumption quality of online shopping, thank you!
