Secrets on milk packaging tape-let you know the real date of milk production

Generally, there will be a production date on the milk packaging (that is for consumers ). There is also a dark sign consisting of English letters and numbers, which is the real date of milk production. So how can we identify the company's dark signs to understand the real production date of commodity milk? General printing on milk packaging: production date: 08 05 10 hdc8 H, of which: production date: 08 05 10 (for consumers), everyone can understand; Code: no one knows what hdc8 H means. In fact, this is the real date of milk production. The content of the code here is: the first English letter represents the year: industry rules A: 01 years B: 02 years C: 03 years D: 04 years E: 05 years and so on H: 08 years... (in some cases, the year is omitted and only months and days are displayed ).
The second English letter represents the month: industry rules A: January B: February C: March D: April E: May and so on E: May .. k: November L: December.
The third English letter and number represents the date: industry regulations
1-9 + A: A1, A2, A3, A4, A5, A6, A7, A8, A9;
Before December 19, 1 was changed to B: B0, B1, B2, B3, B4, B5, B6, B7, B8, and B9;
Before the 20th, 2 was changed to C: C0, C1, C2, C3, C4, C5, C6, C7, C8, C9;
Change 3 to D0 and D1 before 30-31.
Therefore, hdc8 represents the year April 28

This indicates that although the printed milk on the package is the production date: 08 05 10, the actual production date of the milk is April 28, and the difference is 12 days.

Another example
Production date 07 06 01 (for consumers)
Code: geb4 indicates that the actual production date is actually May 14.
The dairy factory can produce several dates in a day. For example, the production date 08 09 19 Code: hib1 (September 11) the production date 08 09 23 code: hib1 (September 11)

The production date on the above two packages is different, but the actual production date is the same, both of which are in July September 11.
Why do milk manufacturers in China do this? Isn't this a fraudulent consumer? It is still caused by Chinese characteristics.
Because the technical conditions of China's milk manufacturers are not up to standard, the bacteria in milk are several times higher than the foreign 100 indicators, the winter is about 200, and the summer is about 400, if high temperature sterilization reduces the nutrition of vitamins and other nutrients in milk (Foreign ultrafiltration technology provides quality assurance), in order to reduce the cost, the milk produced by China's dairy factory is often stored for a short period of time, in addition, the storage, transportation, and mall allocation time. If the actual production date is written, the shelf may have to reach the expiration time, so you should remove it and discard it! Writing a fake production date protects the economic interests of the milk manufacturer (as long as the packaging is not bulging, it will continue to be sold even if it expires, it is a special feature of China that people can earn money if they have nothing to do ). The production date on the above two packages is different, but the actual production date is the same, both of which are in July September 11. By the end of September 17, we had to send the milk in September 19 to various supermarkets. after selling the milk in September 21, we had to send the milk in September 23 to the supermarket. In fact, it was produced in September 11. That is to say, we produced milk in September 11 and September 19 at the same time in September 23. More manufacturers sometimes produce four or five different dates each day.
