Pure milk and fresh milk are two milk products that consumers commonly find in the market, and there are some differences between them:
1.Definitions:
Pure milk: Usually refers to milk that has undergone ultra-high temperature treatment (UHT), which is heated for a few seconds at a temperature of more than 135 degrees Celsius to kill almost all harmful bacteria and spores, thus greatly extending the shelf life. Plain milk can be kept for several months without refrigeration.
Fresh milk: Usually refers to pasteurized milk, which is heated for 15 to 30 seconds at a lower temperature (usually between 63 and 72 degrees Celsius) to kill most of the harmful bacteria, but not to destroy all the bacterial spores. Fresh milk needs to be kept in refrigerated conditions and has a short shelf life, usually a few days to a few weeks.
2.Shelf life:
Pure milk: It has a long shelf life due to UHT processing and can usually be stored for several months at room temperature.
Fresh milk: It has a short shelf life and usually needs to be refrigerated in the refrigerator and consumed within a few days to a few weeks.
3.Storage conditions:
Plain milk: Can be stored at room temperature until the package is opened, after which it needs to be refrigerated.
Fresh milk: It must be stored in refrigerated conditions and kept at a low temperature from production to consumption.
4.Taste and nutritional value:
Pure milk: UHT processing may slightly alter the taste and nutritional value of milk, but overall, pure milk is still a nutritious beverage.
Fresh milk: Due to the lower sterilization temperature, it is generally considered to retain more of its original taste and nutritional value.
5.Packaging & Shipping:
Pure milk: Due to its long shelf life, pure milk can be transported over long distances and does not require cold chain logistics.
Fresh milk: Cold chain logistics and faster shipping are required to ensure it reaches the consumer within the shelf life.
When choosing between plain or fresh milk, consumers may consider factors such as shelf life, taste preference, nutritional value, and storage conditions. Both are good calcium and protein**, and the choice should be based on individual needs and preferences.
