Speaking of bagged milk, it reminds me of a dusty past!
Many years ago, when I had just started working, my habit was to go out early every day and go to work after eating breakfast on the streets, and Wuhan people love to eat hot dry noodles, and so do I. Hot and dry noodles are very dry, usually with a bowl of eggnog, but the time in the morning is more precious, often do not have that time, so I will choose to buy a bowl of hot dry noodles, a noodle nest, a bag of hot milk, hot dry noodles in my hand, eat while walking, after eating it will walk to the station, and then drink some bagged milk, breakfast is still very comfortable.
In my cognitive world, I think bagged milk is affordable, portable, and most importantly, it is also very convenient to heat it, soaking it in hot water for a while, and the milk is heated.
I don't know what happened, but suddenly one day, I bought a whole carton of milk at a milk station near the community, thinking that I would go out every morning to get a bag, which would not save money.
After drinking like this for a week, one Sunday morning, Grandma Wang from the next door took her little grandson to pass by our house, standing at the entrance of the stairs chatting about home, I took the milk and prepared to go out for breakfast, after meeting Grandma Wang, I subconsciously gave the bag of milk in my hand to her little grandson.
After Grandma Wang's little grandson took the milk I handed her, after saying thank you in a milky voice, she looked at me and said: "Uncle, do you have that kind of boxed milk in your family?" I don't like to drink this bagged one? ”
I smiled and said, "Uncle's family only has this milk, so what should I do?" ”
Grandma Wang's little grandson replied to me: "Our family drinks that kind of boxed, this kind of bagged milk, I don't know if my mother let me drink it?" ”
Hearing this, my self-esteem was suddenly made by this child with "ripples" in my heart, not a taste, after simply saying hello to Grandma Wang, I went out for breakfast.
I still remember the mood of that day, five flavors, a child so young, influenced by his parents, felt that the bag of milk I gave her was a cheap commodity, I felt very unpleasant in my heart, the hot dry noodles were not finished, the milk was not drunk, a little self-conscious sulking.
This bagged milk was still sold at breakfast, and a chubby little boy sitting next to me, after eating a bite of oil cake, was arguing to drink milk, and the adults in his family bought a bag of milk like me and gave it to the children, and my heart was suddenly relieved.
Was my own pride at work, so I went home and started researching the difference between bagged milk and boxed milk? Buy milk, understand the 4 differences between bagged boxes, buy the wrong one, not easy to store and perish, poor nutrition.
You can leave a message in the comment area and tell us your opinion? What packaging of milk are you used to buying?
First, the difference between boxed milk and bagged milk?
Today we are talking about the packaging form of milk, from our daily life, the most common are carton packaging and plastic bag packaging, and how are they classified?
Milk packaging form: roof box
The most common kind of carton packaging is the roof box, also called fresh house, which is a kind of paper-plastic composite packaging and is a multi-layer composite film. The outermost layer of the carton is plastic film, the middle layer is fiber, the product is aluminum foil, generally suitable for canning fresh milk, flower milk, yogurt and lactic acid bacteria drinks with high nutritional value and fresh taste, the packaging of this roof box needs to be refrigerated and fresh, it is a high-grade product, and the shelf life is short.
Milk packaging form: Tetra Pak
This packaging form is closed canned, milk is poured into the paper tube, and then cut and sealed, this packaging form, there is no air inside, so it can be stored at room temperature, long shelf life, low cost and high cost performance.
Milk packaging form: sterile plastic bag
This packaging material is specially treated, and the plastic bag has a black coating, which can play a role in isolating light, and its effect of isolating light can not be compared with aluminum foil, because the shelf life of this packaged milk at room temperature is only about 30 days.
In addition to the three packaging forms introduced above, the packaging of milk also has glass bottles, Baileys, Combibloc and other packaging forms, the topics we are discussing today are mainly bagged and boxed, so mainly discuss the above three forms of packaging.
Packaging form classified according to sterilization method: pasteurized milk
Pasteurized milk, also known as sterilized milk, usually uses simple plastic bags, plastic bottles, glass bottles for packaging, so the milk produced by this sterilization method, need to be refrigerated storage and transportation, in the supermarket sales stage also need to be placed in the refrigerator, short shelf life, up to 5 days, milk fresh, of course, this form of milk packaging also uses roof boxes for packaging.
Packaging form classified according to sterilization method: UHT milk
More use of paper plastic in line with the packaging, that is, the Tetra Pak package introduced above, there are pillow and brick shapes, the shelf life is longer, the usual shelf life is about 6 months, storage and sales in a room temperature environment, easy to carry, but the cost of this packaging form is higher, so the sales price of milk is also more expensive.
In addition to the packaging in the form of Tetra Pak, UHT milk is also packaged in aseptic plastic bags, which can save a lot of work, coupled with the low cost of packaging, while ensuring the quality of fresh milk, but also attracted many consumers to buy.
The following focuses on the differences between boxed milk and bagged milk, in addition to the different packaging forms?
1. Differences in nutrition
According to the above introduction, the milk we buy in the supermarket can be roughly divided into pasteurized milk and UHT milk, boxed milk, both pasteurized milk stored in the freezer and UHT milk at room temperature, plastic bag packaging is also the same.
When we buy milk, do not pay attention to the packaging form of milk, more should pay attention to the processing technology of milk, relatively speaking, the nutrition of pasteurized milk in the freezer will be higher, retaining more nutritional elements.
Therefore, if we buy bagged milk and boxed milk at room temperature, it should be that the packaging form of boxed milk will be better than bagged, and in the refrigerated environment, the price of boxed milk must be higher than bagged, the same is pure milk, in the refrigerator, must be the price of bagged milk will be cheaper.
2. Differences in storage conditions
The nutrition of pasteurized milk placed in the freezer will be higher, retaining more nutrients, and the milk placed at room temperature adopts the form of UHT sterilization, and the retained nutrients will be relatively less, and they are boxed and bagged, when we choose, if you choose room temperature milk, that is, UHT milk, the price of bags will be more economical, because the cost of the boxed Tetra Pak package shape is higher.
3. Compare from portability
From the perspective of portability, there must be a prerequisite, if you prefer to buy pasteurized milk stored in the freezer, whether it is boxed or bagged is not portable, because this low-temperature milk needs to be refrigerated and stored, portability is very poor, in the case of carrying, who will carry the refrigerator or ice?
If it is room temperature milk, that is, pure milk stored in a room temperature environment, whether it is boxed or bagged, its portability is very good, from an economic point of view, I am more willing to buy bagged, because the packaging cost of the box will be more expensive, that is, when we buy the same capacity of pure milk, because of the difference in packaging, boxed milk is more expensive than bagged milk, and part of our cost is actually not to buy milk, but the packaging of boxed milk.
4. Light avoidance to compare
Milk, pure milk contains vitamin B2, will affect the quality of milk after being exposed to sunlight, from this point of view, whether it is pasteurized milk in a low temperature environment, or ultra-high temperature sterilized milk in a room temperature environment, carton packaging is better than bagged. This is because bagged milk has poor light protection, while boxed milk has good light protection.
Second, the processing method of milk also has an impact on the choice of packaging?
Above we have been repeating these two forms of milk processing: pasteurized milk and UHT, and the following will tell you about the difference between these two forms of milk processing from the processing form.
Pasteurization
The sterilization temperature is low, most of the nutrients in the milk are retained, but the sterilization is not thorough, and a small part of harmless or beneficial, heat-resistant bacteria are retained, so pasteurized milk needs to be refrigerated and stored, and the storage time is only 3-10 days.
UHT sterilization
High sterilization temperature, can instantly kill all microorganisms and bacteria in milk, which can be stored at room temperature, shelf life up to 180 days, although killing bacteria, but also destroying some nutrients in milk, its nutritional value is not as good as pasteurized milk.
To summarize briefly:
Pasteurized milk can be understood as "pasteurized milk", that is, the fresh milk ordered by the family in the morning, delivered to their own milk box, or the milk sold in the refrigerator in the supermarket.
But all milk seen in a room temperature environment, the premise is pure milk, is UHT milk.
3. How to choose high-quality milk?
The nutrition of pasteurized milk is better than UHT milk, as an ordinary consumer, in daily life, in fact, the chance of buying "pasteurized milk" in the freezer is still very small, usually purchased is UHT milk in room temperature environment, the following focuses on how to choose UHT milk in room temperature environment.
1. The amount of protein content
The main purpose of drinking milk is to supplement protein to our body, so the amount of protein content in pure milk is particularly important, the more protein content, the better the quality of this pure milk, the protein content We can pick up the packaging box of room temperature milk, from the product ingredient list gold view.
2. Judge by the national production implementation standard number
As mentioned above, the nutritional value of "pasteurized milk" must be better than that of room temperature milk, so when we buy "pasteurized milk", we only need to check the standard number in the ingredient list, the production implementation standard number is: GB19645, everyone can buy this standard number, which is also the simplest way.
3. Finally, assist in checking the labeling of raw milk in the ingredient standard
The milk packaging box will be printed with the ingredient list, in the production ingredient list of the ranking of raw materials, the first must be raw milk, only raw milk will be pure fresh milk.
4. Dairy drinks that are confused with milk?
The above has been discussed fresh milk, but in daily life, there is also the existence of modulated milk, which cannot, strictly speaking, be called milk, but should be called milk drinks. Modulated milk will add some other raw materials, although the taste is good, but the nutritional content is not as good as milk.
The most common prepared milk is: breakfast milk, red dates, peanuts, walnuts and other fruity milks, the raw materials of these modified milk are raw milk as much as possible or milk powder.
In addition, there are yogurt, reconstituted milk, etc., if you buy milk in the supermarket for simple and direct purposes, that is, to buy pure milk, then follow the above method to choose.
