One: Smell the single-flower honey, which has the unique flower fragrance of this plant, the mixed honey has the natural flower fragrance, and the fake honey has some sucrose flavor and some spice flavor.

Two: Vision

1. Look at the concentration of honey. Put a chopstick into honey and lift it vertically. Honey with high concentration drops slowly and the viscosity can be drawn. After breaking, it can shrink into honey balls, while fake honey or low concentration honey is the opposite. Even if it can be stretched, the broken wire is not elastic and will not shrink into honey beads.

It is wise to drop a drop of honey in the newspaper. High concentration of pure honey is hemispherical, so it is not easy to soak in newspapers. Low concentration honey or fake honey is easy to soak in newspapers.

Take a glass of water and add a little honey, the real honey will sink to the bottom of the cup quickly and will not melt easily. Stir slowly with chopsticks, there will be filar silk. If it is fake honey, it will soon dissolve in water.

4. Looking at crystallization, the crystallization of honey is related to plant species and temperature. Generally, pure natural honey is easy to crystallize at 13- 14 degrees Celsius. Honey that can be completely crystallized generally has low water content and high concentration, and is not easy to deteriorate, so it is a high-quality honey. Crystallized pure honey is rubbed by hand, which feels delicate and has no sense of sand. False honey is not easy to crystallize or precipitate, and the precipitation is hard and not easy to crush.

Taste: pure natural honey, sweet and sour, soft and delicate, refreshing and soft, slightly spicy in the throat and long aftertaste. Although adulterated honey tastes sweet, it is mixed with sugar or spices. My throat feels weak and my aftertaste is light and short.

1. Drop honey on white paper or toilet paper. If honey seeps out gradually, it means that it is mixed with sucrose and water. Honey mixed with sugar has poor transparency, unclear brightness, turbid shape and poor floral fragrance. Brown sugar mixed with honey is dark in color, while white sugar mixed with honey is light in color.

2. Honey mixed with flour, starch or corn flour is turbid in color and not sweet enough in taste. Put a small amount of honey into a cup, add a proper amount of water to boil, drop a few drops of iodine after cooling, and shake well. If the solution turns blue or red or purple, it means that the honey is mixed with starch.

3. Insert the red-hot wire into the honey. If there is a sticky substance on the wire, it means that there are impurities in honey. If the line is still smooth, there is no impurity. Take honey 1 part, add 2 parts of cold boiled water and 4 parts of 95% alcohol, mix them evenly and leave them for one day and night. If there is no impurity precipitation, the quality is pure.

Take a spoonful of honey and add it to half a cup of very strong cold green tea water. If honey has been polluted by heavy metals, tannins in tea will react with heavy metals in honey to form gray or brown-black salts. The darker the color, the heavier the heavy metal pollution.

5. Insert the red-hot wire into the honey. Real honey is steaming, and fake honey is smoking. Stir honey with chopsticks, you can draw long silk, broken silk will automatically retract, spherical, for the top grade. Mix honey and water at the ratio of 1: 5, and leave for one day. No precipitation is the best product.
