There are many ways to fake honey, and the identification methods are also different. Generally speaking, the simple identification methods are as follows: 1. Mixing it with water; 2. Mixing it with sugar water or adding other sugar products such as high fructose syrup and maltose syrup. Preserved fruit syrup, glucose syrup 3. Mixed with starch 4. Mixed with essence 5. Mixed with amylase
1. Mixed with water
Use a chopstick to insert vertically into the honey, lift it up and drop it in On rough edged paper. If it is real honey, the honey on the rough paper will be a bead. If it is honey mixed with water, the honey dripping from it will spread around.
2. Incorporate maltose
Caramel is also called maltose. Honey mixed with caramel is less likely to crystallize. Take a little honey and put it in a glass, add 4 times the water, mix well, and then add medical alcohol drop by drop. If it is mixed with maltose, there will be many white flocs. Otherwise, it will be slightly turbid and there will be no flocs.
3. Add sucrose
Honey will become solid after being stored at 4 to 14 degrees Celsius for a period of time. After purchasing honey, place it in the fresh-keeping layer of the refrigerator and observe it for 24 hours. Crystallization phenomenon: When real honey is pinched by hand, its crystals will melt quickly. Fake honey has a tingling feeling and melts slowly or does not dissolve. Real honey crystals are fine and soft and can be inserted with chopsticks. Fake honey is hard and cannot be inserted with chopsticks.
4. Incorporate preserved fruit syrup
Preserved fruit syrup is also called white honey. It is a starch syrup produced through biochemical reactions using starch-rich products such as rice. It is difficult to use simple methods. After identification, this product is cheap, and cheap honey is more likely to be added.
5. Add starch
Dissolve and dilute the honey with an appropriate amount of water (do not boil it), add 2 drops of iodine solution, and a blue reaction will prove that it contains starch.
6. Mix in essence
Put a little honey in the palm of your hand, rub it repeatedly for 30 seconds, and then identify the smell. After rubbing, the flavored honey loses its flavor and is left with a syrupy flavor. Real honey still has a light floral aroma.
