Condensed milk is a beverage made of fresh milk or goat milk after disinfection and concentration. It is characterized by long-term preservation.
Condensed milk is a kind of concentrated milk. Condensed milk is a dairy product that removes most of the moisture in fresh milk by vacuum concentration or other methods and concentrates it to about 25% ~ 40% of the original volume. Condensed milk processing can be divided into sweetened condensed milk (sweet condensed milk), light condensed milk, skimmed condensed milk, semi-skimmed condensed milk, colored condensed milk, fortified condensed milk and blended condensed milk due to different raw materials and added auxiliary materials. ? In the past, China mainly produced full-fat sweet condensed milk and light condensed milk. In recent years, with the development of china dairy, condensed milk has withdrawn from the mass consumption market of dairy products. However, in order to meet the special requirements of different consumers for the concentration, flavor and nutrition of fresh milk, the "concentrated milk" produced by moderately concentrating (flashing) fresh milk with appropriate concentration technology will still have a certain market.
As early as 5,000 years ago, ancient Indians and Egyptians regarded milk and goat's milk as important foods and drinks. Milk goes bad easily, and people have been exploring ways to prevent it from going bad. It is said that in the13rd century, the Mongolian army led by Genghis Khan of China carried a paste-like condensed milk when fighting in Eurasia.
1827, n in France? Appel first invented condensed milk technology to make condensed milk. Appel once canned sugar-free condensed milk and gave it to the French navy at that time. But the industrial production of condensed milk is 30 years later. American g? On a sea trip, Boden witnessed the tragedy of several babies in the same boat who died from eating spoiled milk, so he came up with the idea of studying the preservation technology of milk. After repeated research and consulting many people, he finally developed the technology of concentrating milk to about 1/3 of its original volume by vacuum distillation to produce condensed milk. He also added a lot of sugar to condensed milk, which reached more than 40% of the weight of the finished product, actually inhibiting the growth of bacteria. 1856, Boden obtained the invention patent of sweetened condensed milk. From 65438 to 0858, Boden established the first condensed milk factory in America. The canned condensed milk produced by Boden was used by the army in the American Civil War (186 1- 1865), which proved its practicability.
1866, American Becky also established a condensed milk factory to produce sweetened condensed milk. Meinberg, a technician from Baiji Company, also studied a new method to produce condensed milk. Before that, people didn't know the real reason for the deterioration of fresh milk. 1857 famous French biologist and chemist l? Pasteur first discovered that food corruption was caused by microbial reproduction. Pasteur invented the heating sterilization of wine and beer in 1865 and 1873 respectively. Inspired by this, Meinberg invented a new milk concentration method in 1884. After canned condensed milk, it was sterilized at high temperature to produce sugar-free condensed milk which can be preserved for a long time.
Ingredients: There are more carbohydrates and ascorbic acid (vitamin C) in condensed milk than in milk powder, while other ingredients such as protein, fat, minerals and vitamin A are less than in milk powder.
Edible: After the iron cover is opened, if condensed milk can't be eaten at one time, and there is no refrigerator at home, it is easy to deteriorate, rot and infect bacteria, but milk powder does not have this shortcoming.
Packaging: condensed milk is mostly packed in tin cans, and milk powder is packed in plastic bags or tin cans.
Shape: condensed milk is liquid and milk powder is solid particles.
Condensed milk is a kind of dairy products, which is made by evaporating fresh milk to 2/5 of its original capacity and then adding 40% sucrose to cans. Some people are influenced by "concentrated essence" and give their children condensed milk instead of milk. This is obviously wrong. Condensed milk is too sweet and must be diluted with 5 ~ 8 times of water. But when the sweetness meets the requirements, the concentration of protein and fat is often reduced by half compared with fresh milk. Infants and young children, if fed, will certainly not gain weight, look pale and get sick easily. If water is added to condensed milk to make the concentration of protein and fat close to that of fresh milk, the sugar content will be high. Feeding such "milk" to children is also easy to cause diarrhea in children. In addition, if children are used to sweetness, it will bring difficulties to add complementary food in the future.

/kloc-One day in the middle of 0/9th century, a passenger ship sailed for new york from the sea. Many people on board hold the railings and look at the water and sky outside, enjoying the spectacular natural scenery.
The ship was sailing when suddenly there was a scream on the deck, followed by a cry. This sudden scene caused a man named Gail? The American in Burton paid attention, and he immediately rushed over and squeezed through the crowd of onlookers. As soon as he saw it, he suddenly felt that the air was frozen. Several women are holding a sea burial ceremony for some lovely babies. Grier Burton resisted grief and asked the women about the cause of the baby's death. The thing turned out to be this: at that time, although people generally fed their babies with milk, they didn't know how to preserve it so that it would always be fresh and wouldn't go bad. These young people died of poisoning after eating spoiled milk. Gore Burton was very sad. During the whole voyage, sad scenes always hurt his heart deeply, and the bodies of cute little creatures always appeared in front of his eyes.
Gore Burton made up his mind to work out a way to preserve fresh milk. After returning to new york, he immediately devoted himself to research and development, getting up early, eating and sleeping every day. He consulted many people, and after numerous experiments, he finally found a method of vacuum distillation, which can successfully achieve the purpose of preserving fresh milk. Gore Burton was not carried away by this achievement. He continued his research and experiment. He also dissolved a proper amount of sugar in milk, which further improved the ability of milk to prevent bacterial corrosion.
Gore? Burton named his product "condensed milk". He founded the world's first condensed milk processing factory in new york on 1853. Condensed milk is very popular with mothers. Two years later, Ger Burton used the canned packaging that came out soon for the preservation of fresh milk, and condensed milk became what we are familiar with now.
