How to tell reduced milk from fresh milk?
Answer: There are two kinds of liquid milk: normal temperature milk and low temperature fresh milk. Normal temperature milk can be made from reduced milk or raw milk.
Reduced milk is made from cow milk powder, and there are many liquid milk on the market at present. This kind of milk has low production cost and does not need to build a milk source base. It is better to drink this milk with cow milk powder.
Raw milk is raw milk squeezed directly from cattle, also called fresh milk.
Fresh milk at low temperature usually refers to milk pasteurized and homogenized with raw milk, also known as pasteurized milk, commonly known as fresh milk. This milk does not contain any stabilizer, thickener, emulsifier, etc. Enterprises producing fresh milk should have enough raw milk, which can be purchased from local herdsmen or dairy farmers, but it is best for enterprises to have their own milk source base, which is conducive to ensuring the health of dairy cows and the nutrition and hygiene of milk. The construction of milk source base needs a lot of money, so the enterprises that produce fresh milk need a certain scale.
Some unscrupulous enterprises label the reduced milk as "fresh milk" for sale, which harms the interests of consumers, and consumers should distinguish it when buying fresh milk. The simplest way to distinguish is to see whether the enterprise has a certain scale of milk source base or whether the source of raw milk is clear.
Does milk mean drinking milk?
A: Now all kinds of milk drinks are contained in the containers of shops and supermarkets. Many consumers think that milk drinks are milk. Some children pursue taste unilaterally and like to drink milk drinks, but many parents mistakenly think that they don't have to drink milk after drinking milk drinks. In fact, milk drinks are by no means the same as milk. Because the protein content of milk beverage is very low, other nutrients can't be compared with milk. If parents always treat milk drinks as milk for their children, it is likely to affect their growth and development. Some people mistakenly think that yogurt is also a milk drink. In fact, yogurt is fermented by milk inoculated with lactic acid bacteria under certain conditions. Its nutrients are similar to milk, its flavor is better and it is easier to digest. People who are allergic to milk can drink yogurt.
The way to distinguish milk drinks from milk is to look at the protein content on the package.
