Is there any difference between the 7 day and 15 day shelf life of pasteurized milk?

1. The nutritional value is different.

1) Shelf life.

Fresh milk for only one day is pure fresh milk, and the nutritional value of unprocessed milk is higher than that of fresh milk with 7 degrees for 4 days.

2) Fresh milk with a shelf life of 7 days is pasteurized.

Sterilized, the nutritional value is not unprocessed, and the nutritional value is high only with a one-day shelf life.

2. The storage conditions are different.

1) Pasteurized fresh milk must be stored at a low temperature of 0 4 degrees, more than 4 degrees, bacteria will multiply in large numbers, and low temperature refrigeration can be shelf life for up to 7 days.

2) Pure fresh milk that has not been pasteurized can be stored for one day at low temperature and refrigeration, so it must be drunk on the same day.

3. The shelf life is different.

1) Pasteurized fresh milk can be stored for 7 days.

2) Unpasteurized fresh milk can only be stored for 1 day.

The sterilization temperature is not the same, the kind of sterilization with a shelf life of 3 to 7 days is only 70 to 80 degrees, which will retain the vitamins and lactic acid bacteria in the milk, and if you want it to have a long shelf life, and it can be stored at room temperature, (the key point is stored at room temperature), then it must be sterilized at a high temperature of 130 degrees, so that the vitamins and lactic acid bacteria in the milk in the milk will be killed. The nutritional content is very different.

It is all pasteurized, and it is possible that the milk is not the same as the variety of milk, so the degree of contamination will be different, resulting in a different shelf life of the milk. In general, this kind of food with a short shelf life is proven repeatedly.

The shelf life of 15 days is high-temperature pasteurized milk, and the nutritional value and taste are not as good as pasteurized milk at 65 degrees. Pasteurized milk generally has a shelf life of no more than 7 days, so you need to pay attention to it when buying pasteurized milk.

Sterilization form, sterilization temperature, packaging form and so on.

Each has its own advantages, 7 days is recommended.

My dear is sorting out the answer for you urgently, typing is slow, you will be in about three minutes, please wait a while

The shelf life of pasteurized milk is 7 days and 15 days, and its shelf life is not the same. With a shelf life of seven days, it is stored for a shorter period of time, and with a shelf life of 15 days, it will be stored for a longer time. However, the storage time of fresh milk is usually about a week

Dear The difference between the 7-day and 15-day shelf life of pasteurized milk has been sorted out as follows: 1. The storage time is different, the difference between the two is 8 days, and after buying in large quantities, pasteurized milk with a shelf life of 15 days can be drunk without being too anxious. 2. The nutritional value is different, pasteurized milk with a shelf life of 7 days will contain more nutrients, and fresh milk with a shelf life of 15 days may contain more preservatives.

Therefore, it is recommended that you buy fresh milk with a shelf life of seven days when you usually buy pasteurized milk

Hope the above can be helpful to you ha, dear [warm] [warm] [warm].

Some people buy fresh milk and find that it has two shelf lives.

One shelf life is seven days, one shelf life is fifteen days, they are all fresh milk from the appearance, the difference is not big, what is the difference between the shelf life of fresh milk of 15 days and seven days? Let's take a look at the difference between fresh milk with a shelf life of 7 days and 15 days.

1) Shelf life.

Fresh milk with a shelf life of 7 days has a shorter shelf life, and it may spoil within a few days of buying it. And fresh milk with a shelf life of 15 days has a longer shelf life, so you don't have to worry about it going bad all at once, you can buy a little more every time you buy it, or you don't have to rush to drink it at home.

2. Nutritional value.

Fresh milk with a shelf life of 7 days will contain more nutrients than fresh milk with a shelf life of 15 days, and fresh milk with a shelf life of 15 days will add more preservatives in order to prolong its shelf life with lead.

3. Sterilization technology.

Fresh milk with a shelf life of 7 days is generally sterilized by bus, which can retain the nutrients and flavor of milk to the greatest extent, and the fresh milk sterilization method with less loss is required, and the cold chain is not easy to deteriorate during transportation. The fresh milk with a shelf life of 15 days mostly adopts ultra-high temperature sterilization technology, which can kill almost all the bacteria in the milk, but also damage the nutrients of the milk, and it can be transported at room temperature.

Compared with fresh milk with a shelf life of 7 days and 15 days, it is definitely more nutritious with a shelf life of 7 days.

Many people like to drink fresh milk, but find out the shelf life of fresh milk.

Much shorter than you imagined, how many days is the shelf life of fresh milk? Some people find that the shelf life of fresh milk is seven days, but they are not sure whether it starts from the day of manufacture or the date of the market.

The shelf life of fresh milk ranges from 2 to 7 days, fresh milk is generally made by bus sterilization method, which belongs to low-temperature fresh milk, its taste is relatively rich, and most of the nutrients in the milk are retained in the sterilization process, so it has a shorter shelf life, and it should be drunk immediately after buying fresh milk.

The shelf life of fresh milk is seven days from the date of production, for example, the production date on fresh milk is March 8, then the expiration date of its mold cover is March 15. Because the shelf life of fresh milk is short, only one week, so when people buy fresh milk, they must look more at what day it was produced, and try to buy fresh milk that has just been produced.

Fresh milk is recommended not to drink after the expiration date, although at this time the fresh milk looks and tastes similar to the fresh milk in the shelf life, but in fact, it has produced a variety of bacterial ridges because of the expiration date, once the expired yogurt, the bacteria in it will enter people's stomachs, affecting intestinal health, causing diarrhea and abdominal pain.

and other discomforts.

1. The time that can be stored is different, the difference between the two is 8 days, and after a large number of purchases, fresh milk with a shelf life of 15 days can be drunk without being too anxious. 2. The nutritional value is different, fresh milk with a shelf life of 7 days will contain more nutrients, and fresh milk with a shelf life of 15 days may contain more preservatives.
