Mengniu Trensu.

Well-known dairy products.

The brand, "Terensu" is derived from the Mongolian language.

It means "gold medal milk". It is rich in nutritional value and more expensive than ordinary milk, but there are many counterfeit Trensu on the market, and now we will teach you some ways to distinguish the authenticity of Trensu.

Method steps.

Looking at the name, some are copycats, although the packaging is very similar, but it is not Trensu, or a few words more than Trensu, such as Trensu flavor drink.

Open it to see if the points code can be used, if it can't be used, it's fake, and those that can't be scratched are also fake.

There is also to see whether the sealing sticker is complete or not, generally incomplete is to use the real box to put fake milk, and the points code inside are real, here we should pay special attention to the incomplete milk of the sealing sticker.

Look at the firmness of the straw, like the kind of hand that falls off as soon as you touch it is absolutely fake, no matter how similar the appearance is, there is still a big gap with ** in details.

Tear open the milk carton, now the Trensu box is bought in the vertical yellow paper, if it is white, it is likely to be fake. You can also see by looking at the anti-counterfeiting code at the bottom of the box, there is no fake one.

When you are sure that it is a fake, you can return it, and if you can't return it, don't be reluctant to throw it away, and don't drink fake milk for the sake of your health.

Feed dogs, cats, chickens, ducks and geese, don't drink it.

1.The real Trensu has an integral in it, like a letter, and there is a string of numbers in it, and this string of numbers can be integrated, but the fake Trensu milk does not. 2.

We can scan the code to score, or we can hit ** to the official of Telunsu to score, and it is true that we can accumulate points. However, it is generally sold in the market.

You can scan the barcode on the box.

Hello, I have seen your question and am sorting out the answer, please wait for a while First, the identification of mixed buffalo milk. According to the principle of density of liquids, the normal specific gravity of milk is between 20 o'clock, and when water is added, the specific gravity of milk decreases. Experiments have shown that for every 10% water added to milk, the specific gravity decreases.

Therefore, we can identify adulterated buffalo milk by measuring specific gravity. The specific method is to slowly pour 200ml of evenly mixed milk into a 500ml graduated cylinder, and put the hydrometer into the graduated cylinder at 20 times (the hydrometer should not be in contact with the cylinder wall). If the value is lower than that, it can be concluded that the milk is mixed with buffalo.

2. Identification of milk mixed with soy milk. Take 10ml of milk and put it into a 25ml test tube, add iodine solution, shake well and check its color, if the liquid is orange-yellow, the milk is normal milk; If the liquid is grayish-green, it can be determined that soy milk has been added to the milk. The principle is that soy milk contains almost no starch compared to cow's milk, but it contains a lot of carbohydrates, which usually show a gray-green reaction when exposed to iodine.

3. Identification of starch-blended milk. Take 10ml of milk and put it in a 25ml test tube, heat and boil, cool and add 2ml of iodine solution and shake. If there is a blue-purple precipitate, it means that the milk is adulterated with starch.

The principle is that the gelatinized starch has the property of turning blue-purple when exposed to iodine.

Fourth, the identification of alkali milk. Milk is prone to rancidity under the action of microorganisms, and in order to cover up the rancidity, some unscrupulous operators will add a certain amount of edible alkali to the milk. The method to identify this alkali-blended milk is to take 10ml of milk and put it into a 25ml test tube, then add 5ml of rose red acid ethanol solution, shake well and observe the color.

If there is a rosy red color, it means that edible alkali has been added to the milk, and the darker the color, the greater the alkalinity. If it is normal milk, it should be orange-yellow in color. 5. Identification of salt-blended milk.

In order to prevent milk from spoiling, some milk producers often add a certain amount of table salt to the milk. The method of identifying this milk is to take 5ml of silver nitrate solution and put it in a 10ml test tube, then add two drops of 10% potassium dichromate solution, mix well, add 1ml of milk, shake well and observe its color. If the solution is yellow, it means that the milk has been mixed with a certain amount of table salt.

The principle is that when silver nitrate and potassium dichromate are mixed with standard milk, they will show a red reaction, and when the milk is mixed with table salt, when the chloride ion exceeds the standard, silver chloride precipitation will occur, resulting in yellow color. 6. Identification of gelatin-blended milk. In order to change the characteristics of water-blended milk, some milk counterfeiting companies often add a certain amount of gelatin to the milk to make up for it.

The identification method for this kind of milk is to take 10ml of milk and put it in a 150ml Erlenmeyer flask, then add 10ml of mercury nitrate solution, shake it vigorously and let it stand for about 5 minutes, and then filter. Then add the same volume of saturated picric acid solution to the filtrate, if there is a yellow precipitate, it means that the milk is mixed with gelatin, otherwise it is normal milk.

1. Look carefully at the name, some imitation names have some small details differences. Or maybe it's a few more words than Trensu. For example:

Trensu flavored drinks, etc., the color and clarity of the logo. 2. There is a point code on each one to see if it can be scratched or whether it can be used. 3. **'s Trensu has an integral in it, like a letter, and there is a string of numbers in it, and this string of numbers can be integrated.

Hit ** to the official of Telunsu to accumulate points, and the accumulation is**. Contrarily. However, there will be no fakes in the general market, and the cost of this kind of counterfeiting is very high.

4. Some small things such as straws in Telunsu will not be of poor quality. The fake straw is transparent. 5. The most direct and simple way is to tear open the Trensu milk carton, **The inside of the Trensu box is a longitudinal yellow paper, if it is white paper, it is necessary to consider the authenticity or falsehood.

The real Trensu has a label on it, and there are anti-counterfeiting marks, if you can't tell the difference, you can go to the big mall to buy it.

1 There will really be a point in it, like a letter, and there will be a string of numbers in it, and this number can be credited.

2, we can scan the code points, or hit **to the official** can also be points, there are points is real.

3.Observe the degree of sealing.

The date of manufacture of Trensu is only necessary to look at the third to tenth digits of the number.

The date of manufacture of Trensu is marked at the top of the box and is a string of characters with numbers and letters.

Take 1a20210312cf 0512:12 as an example, you don't need to look at other characters, you only need to look at the third digit to the tenth digit of the sedan number, that is, the 20210312. The first 4 digits represent the year, indicating 2021, the fifth to sixth digits represent the month, 03 indicates that it is March, the seventh and eighth digits represent the date, and 12 represents the production on the 12th.

Milk Shopping Guide:

The main products sold in the market are ultra-high temperature instantaneously sterilized milk (i.e., milk stored at room temperature). When purchasing, in addition to buying in a qualified market, it is also necessary to see whether the packaging is intact and undamaged, whether the label content is complete, and pay special attention to the shelf life. Pinch the texture of the package, if it feels very hard, there may be deterioration.

If the milk is thin and whitish, the fragrance is reduced, and it is not easy to hang on the wall; Or drip on the glass sheet, the milk droplet is not formed, easy to disperse, it is mixed with milk. If it cools slightly after boiling, curdling or flocculent condensation appears on the surface, indicating that the milk is not fresh or has deteriorated.

The Trensu has an integral in it, like a letter, and there is a string of numbers in it, and this string of numbers can be integrated. Hit ** to the official of Trensu to go to the points, and the accumulation is **. Contrarily.

However, there will be no counterfeits sold in the general market, and the cost of this kind of counterfeiting is very high. But it is not excluded that there are copycats.

Looking at the packaging, the fake one will have a little flaw.
