Why does Tetra Pak paper packaged milk taste stronger? Is the milk packed in carton and soft plastic the same in quality?

Tetra Pak bricks and Tetra Pak pillows
in supermarkets, Tetra Pak bricks and Tetra Pak pillows are generally scattered or stacked in boxes. Generally, these two kinds of packaged milk cannot be seen in the freezer, because Tetra Pak bricks and Tetra Pak pillows are packaged at room temperature, that is, milk that can be stored at room temperature
milk is so delicate, why can it be stored at room temperature? It turns out that some packages of “ultra-high temperature sterilized milk” packed with Tetra Pak bricks and Tetra Pak pillows are milk processed by “UHT”, which is actually the English abbreviation of ultra-high temperature sterilization. Different from pasteurized milk, ultra-high temperature sterilized milk uses a high temperature of about 134 ℃ to instantly disinfect the raw milk for 4 seconds, kill all harmful bacteria and microorganisms in the milk, and then put it into the sterile packaging of Tetra Pak brick or Tetra Pak pillow under sterile conditions to meet the commercial sterility standard. Tetra Pak bag is a six layer composite package composed of paper, aluminum and plastic, which can effectively isolate milk from air, light and bacteria. Therefore, it can be stored at room temperature, and the shelf life is long. Tetra Pak pillow can reach 45 days and Tetra Pak brick can reach 6 to 9 months. Tetra Pak milk is also called “normal temperature milk”, but some people also call it “sterilized milk” or “UHT milk”
Tetra Pak milk is very convenient to consume because it can be stored at room temperature. Without the requirement of refrigeration, you can drink anytime, anywhere. However, it should be noted that Tetra Pak can be stored at room temperature when sealed, but if you can’t finish drinking after opening the package, you must put it in the refrigerator for refrigeration
from the perspective of nutrition, although this kind of milk is sterilized at ultra-high temperature, the disinfection time is very short, only about 4 seconds. Therefore, the main nutritional components, such as protein and calcium, are basically not damaged. Moreover, since the disinfection temperature exceeds 100 ℃, it can effectively kill all kinds of pathogenic bacteria that may exist in the raw milk, so as to maximize the safety of the milk
aseptic plastic bags
a kind of milk in plastic bags can also be seen in supermarkets. It looks a bit like pasteurized plastic bag milk, but the shelf life can reach 30 days. This kind of packaging is aseptic plastic bags that have just been put on the market. Unlike pasteurized plastic bags, the UHT milk contained in them has also been specially treated, so the shelf life at room temperature has been greatly extended. Compared with sterile paper packaging, although this kind of packaging is more economical, it will break the package or taste, which will affect nutrition and taste. It is suggested to pay special attention to whether the packaging is intact when purchasing.

due to different sterilization and packaging processes, the taste is slightly different, and the shelf life is also different. For example, Tetra Pak milk is treated with ultra-high temperature sterilization (UHT), which can be stored for 45 days and cartons for 6-9 months. Therefore, there are differences in production costs. The net content of the same price must be different. As for which one to choose, it depends on whether your consumption concept tends to price or quality

look at the packaging and know milk

with the strengthening of health awareness, milk has increasingly become an indispensable food in our life. However, many consumers feel at a loss when purchasing: there are so many kinds of milk products on the market, which is good? Next, we will teach you how to buy milk through packaging

aseptic paper packaging
now more and more consumers like to buy safe, convenient and environment-friendly aseptic paper packaging milk. The common ones are Tetra Pak brick and Tetra Pak pillow packaging. In supermarkets, Tetra Pak bricks and Tetra Pak pillows are generally scattered or stacked in boxes. The packaged milk is “normal temperature milk”, or “sterilized milk” or “UHT milk”
Tetra Pak bricks and Tetra Pak pillows are packed with “ultra-high temperature sterilized milk”. Some packages are written with “UHT” processed milk. UHT is actually the English abbreviation of ultra-high temperature sterilization. The packaged milk is sterilized for 4 seconds at a high temperature of about 137 ℃, killing all harmful bacteria and microorganisms in the milk, and then loaded into Tetra Pak brick or Tetra Pak pillow sterile packaging under sterile conditions. From a nutritional point of view, although this milk is sterilized at ultra-high temperature, the disinfection time is very short, so the main nutritional components, such as protein and calcium, are basically not damaged
reminder: Tetra Pak packaging is composed of six layers of paper, aluminum and plastic, which can effectively isolate milk from air, light and bacteria. It does not contain preservatives. It can be stored at room temperature and has a long shelf life. Tetra Pak pillow can reach 45 days and Tetra Pak brick can reach 6 to 9 months. Tetra Pak packaging can be stored at room temperature when sealed. If you can’t finish drinking after opening the package, you must put it in the refrigerator for refrigeration
sterile plastic bags
a kind of milk in plastic bags can also be seen in supermarkets. It looks a bit like pasteurized plastic bag milk, but unlike pasteurized plastic bags, UHT milk and packaging materials in it have also been specially treated, so the shelf life at room temperature has been greatly extended, which can reach 30 days
reminder: this kind of package is relatively economical, but it is easy to break the package or taste, which will affect nutrition and taste. Pay special attention to whether the package is intact when purchasing
roof bag
roof bag, also known as fresh house, is a kind of paper plastic composite packaging. It looks a bit like a small house. It contains pasteurized milk, referred to as pasteurized milk or sterilized milk. In supermarkets, they are usually placed in freezers. The fresh milk is sterilized at the standard temperature of 72-76 ℃ for about 15 seconds. Pasteurized milk is a kind of “low-temperature sterilized milk”. The harmful microorganisms in raw milk have generally been killed, but some other microorganisms will be retained. Therefore, this kind of milk is required to be refrigerated in an environment of about 4 ℃ from leaving the production line to transportation, sales, storage and other links, so as to prevent the microorganisms in it from becoming “active”
reminder: the shelf life of pasteurized milk is generally about 7 days. Consumers must pay attention to the quality of milk when purchasing, preserving and drinking pasteurized milk. Especially with the coming of summer, the imperfect cold chain links are easy to make such milk “swell” and deteriorate, and the stale milk can no longer be drunk.

maybe it’s different. The price of paper packaging is expensive.

in fact, the quality is not directly related to the thickness. Milk can be added with water or thickener. Adjust it at will
