How can saffron distinguish the real from the fake? How to distinguish saffron from fake

1. Water soaking method: take a few saffron filaments, put them in hot water, and observe the discoloration of the water. Although the filaments of saffron are red, its active ingredients are yellow after soaking in water, while fake saffron can only be dyed red and remain red after soaking in water.

2. Observation method: The tip of the filament of the genuine product is swollen with a bell mouth.

The authenticity of saffron can be distinguished by soaking, wiping, pressing, and iodine.

1. Water soaking method: After soaking the real saffron in water, you can see that the obvious yellow active ingredients are released from the surrounding of the filament, and the water will eventually be dyed golden yellow.

2. Wipe method: The traces of genuine saffron after wiping it vigorously on white paper are yellow or orange.

3. Pressing: After pressing the genuine saffron, there will be no oil stains on the paper.

4. Iodine wine method: iodine wine does not change blue after dripping into genuine saffron.

Teach you to distinguish between real and fake saffron.

1 real saffron: real saffron is made of purple-blue saffron stamens, take a sample and dip it in water a little, the water is dyed golden yellow and gradually downward, it will not be broken immediately in the water, and the water is bright light yellow, the oil-free floaters on the water surface are observed with a magnifying glass, one end of the genuine product is expanded into a trumpet, and there are cracks on one side.

Fake saffron: fakes are the stamens of other flowers or even radishes cut into very fine shreds, and then dyed, after soaking in water, radishes will be broken, dyed will be very judged to touch the mountain and fade quickly, digging and water will turn red or orange yellow and have oily floats, adulterated varieties have saffron stamens, daylily dyeing, maize flower columns, stigmas, safflower, lotus whiskers, etc.

2. True saffron: The red color of saffron is not the color of dyeing, press hard with facial paper, and there will be no color residue on the paper.

Fake saffron: The color of fake saffron is dyed later, and a lot of pigment is on the surface of the material, and the pigment will fall off after pressing hard, and there will be red residue on the paper.

3 True saffron: Put the saffron on a white paper, spread it out and observe carefully, the real saffron is the stamen of the flower, therefore, each is trumpet-shaped, and some of them are broken.

Fake saffron: Fake saffron is mostly dyed with edible glue, which is not trumpet-shaped, and is mostly irregular strips or cylindrical.

4 True saffron: Remove a small piece of saffron, put it on a glass plate, add a drop of dilute sulfuric acid, and the real saffron will appear dark blue around the flower, and then slowly turn to purple, and then turn reddish-brown.

Fake noisy saffron: Because it contains pigment, dropwise addition of chemical test liquid will directly lead to the dissolution of pigment, and the reddish phenomenon will appear directly.

At present, there are a large number of unscrupulous merchants on the market** "fake saffron", and the methods of counterfeiting are diverse, and the common ones are dyed and impersonated with other stamens or fake flowers in real saffron. Here are a few ways to identify saffron. How to distinguish a real saffron from a fake

The easiest and most direct way to identify a real saffron is to carefully observe its appearance, including the color, shape, size, etc. of the saffron. It is best to put the saffron on a white piece of paper and spread it out to take a closer look. We have to know that the real saffron is long, dark red, oil-free and shiny, and it is brittle and easy to break after drying.

If the saffron clumps together, then it is most likely mixed with water. Even if some of the saffron is broken, each one is trumpet-shaped, and we can put the saffron under a magnifying glass to observe it so that it can be seen at a glance what shape it is. Fake saffron is generally light red in color and has a pronounced luster on the surface.

Smell the smell of saffron genuine has a strong floral fragrance, although the fragrance is strong but not pungent. Generally, it is difficult to reach this concentration in the fragrance of fakes, most of them are faint, and some cannot be smelled. If you don't know anything about saffron when you buy it, you can go to a professional pharmacy to smell it.

Saffron is a drug that we can soak in water when identifying. True saffron is mainly composed of stamens, which do not break immediately when soaked in water, and the water is light yellow. Fakes are usually made up of other petals or doping, and when soaked in water, the petals will break quickly, fade faster, and the water will turn red or orange.

When identifying saffron with acupressure, you can also use a tissue to take a small amount of saffron wrap and squeeze it in the middle, pay attention to the paper if it is clean and not stained with dust and other pollutants, otherwise it will affect the results of identification. The genuine saffron will not leave any stains or other impurities after extrusion. However, if there are obvious stains on the paper, it is generally fake.

Powder identification. It is understood that the powder of saffron is generally orange-red, and the color of the powder is likely to change due to the doping of other substances, and the general false saffron is mostly red.

Notes:

When buying saffron, it is best to go to a regular pharmacy to buy it, which is more secure. References

The methods of identifying the authenticity of saffron are: observation method, soaking method, wiping method, pressing method, and smelling method.

1. Observation.

The part of saffron medicine is the stigma of the pistil of the saffron flower, which is red filament one by one after picking and drying, and the tip of the filament is flared and expanded. Fakes with saffron can be identified by observation. You can see the difference between saffron and grass saffron, saffron is a filament, while grass saffron is a small flower.

Second, the method of soaking in water.

The soaking method is mainly used to identify dyed fakes. Although the saffron filament is red, its active ingredient is yellow at a relatively low concentration. And dyed fakes can only be dyed red, soaked in water red.

3. Wipe method.

The wiping method is also mainly used to identify dyed pseudosaffron. The operation method of wiping to identify saffron is to take a sample of saffron filaments, and then rub them vigorously on white paper, and then look at the color of the wiping traces, the traces of genuine saffron are yellow or orange, and the wiping marks of dyed fake saffron are red. If the marks are not easy to develop, you can dip the filaments in water first and then wipe them.

Fourth, the compression method.

The compression method is mainly used to identify fake saffron that is soaked in oil for weight gain. If the saffron looks moist to the touch and has an oily shine, you can use the pressing method to identify it. The operation method to identify saffron by pressing method is to take a small sample of saffron, place it between two layers of paper and press it hard, and then observe whether there are oil stains on the paper.

If there is an oil stain, it means that it is a fake saffron soaked in oil to gain weight. At present, there are relatively few fake saffron soaked in oil on the market, and it is easy to identify by the characteristics of wet, oily, and oily when pressed.

Fifth, smell the method.

Authentic saffron has a very strong floral fragrance and is very special, while fake or adulterated goods have a faint or even unsmelling taste.
