Sodium saccharin is a chemically refined food additive, and the fake sodium saccharin is generally produced by adding some sucrose to it. However, when we buy saccharin sodium, we want to buy pure saccharin sodium, so how do we identify adulteration of sodium saccharin?
1. Distinguish from the appearance. First of all, sodium saccharin and sucrose are different in appearance. Saccharin sodium generally presents transparent crystal shape, while sucrose has smaller particles and lower transparency. The appearance of the two is different. At the same time, if sucrose is put in the air for a long time, it will appear the phenomenon of sticking.
2. Distinguish from the taste. Under normal circumstances, saccharin sodium will feel slightly bitter if consumed in large quantities, but bitterness will not appear if sucrose is consumed.
3. Distinguish by doing chemical test. Chemical analysis shows that sodium saccharin will precipitate powder when it encounters concentrated hydrochloric acid, but sucrose will not. We can do a test in a test tube to see.
The most commonly used methods to identify the adulteration of sodium saccharin are the above three methods. When purchasing sodium saccharin, we can walk around and find a good sodium saccharin factory before purchasing.
Therefore, it is very important to know about the sodium saccharin factory before purchasing sodium saccharin.
