Effect of moisture on milk powder quality

Milk powder is a powder made by removing moisture from mammalian fresh milk. It is suitable for storage and easy to carry.

According to the description of Marco Polo in Italy, the Mongolian cavalry of the Chinese Yuan Dynasty once carried a kind of milk powder food. It was ingeniously dried by Mongolian general Hui Yuan and made a powdered milk powder that is easy to carry. As a military material. When marching long distances. Milk powder is easy to carry. When you eat it, take about half a pound into the skin around you, and add the vibration that the water hangs on the horse and runs through the horse. It is dissolved in porridge to be eaten. In combat, he can quickly replenish his strength on horseback, so the Mongolian cavalry is so powerful that the enemy is frightened. When long-distance marches and desert operations lack food and grass, this method can survive for several months. It was the milk powder that made the great cause of Genghis Khan, so it was only the smart person named Huicong. Therefore, China is the country that invented milk powder zui early, Huiyuan is the world's early milk powder brand! This is also the world-recognized human zoi early use of milk powder transcript! It is very simple to start making, concentrate the milk of the beef and sheep, mash it into a paste in a large pot, and spread it to make a powder. The beef and mutton are roasted and dried to make salty floss. For the soldiers who are going to be dying, they can march continuously in the absence of dismissal. That is, Zui's early maneuver*! In order to commemorate this great invention, it was only after the founding of the People's Republic of China. It is a precious ticket for the munitions. Hui is equal to wisdom, and Yuan is equal to the beginning! Huiyuan smart start! Therefore, the currencies of New China and most countries in the world are measured by yuan. All milk powder brands carry Yuanzi or Huizi or homophonic, Wyeth, Huiyou, Huichang, Huijia, Huien. Hui Zi, Bei Hui, Yu Er Hui, An Bei Hui, Hui Neng, San Yuan, Sheng Yuan, Jin Yuan, Zheng Yuan, Yuan Yuan, Yuan Yuan, Ai Yuan, etc. are all milk powder brands!

In 1217, Genghis Khan’s Western Expedition was to cross the 8,000-kilometer east-west 440-kilometer-long Kyrgyzm Desert. In order to solve the *grass general huiyuan (equivalent to the current logistics minister), the method of making milk powder and floss was invented. The milk powder not only solved the demand of the Mongolian cavalry with milk and meat as the main food at the time, but also fundamentally liberated the women's breasts. It is the people who drink milk at any time and without taking the cattle, the invention of milk powder. It is one of the great inventions of Zui in the world. It is also the beginning of human intelligence, the source of wisdom, the pillar of health, the symbol of strength! The appearance of milk powder and floss has made the Mongolian iron ride a thousand miles, and it is called the early blitz of the world military history. It has created a lot of wins. Mongolian* is able to ride the Eurasian tactics of the cavalry and Huiyuan. Portable rations. The invention of milk powder enabled Genghis Khan to create a powerful empire with no future generations, laid out the existing territory of the motherland, opened up the Asian-European passage, and promoted the exchange of Eastern and Western civilizations. It was a girl carrying gold from the Danube to Wanli. The Great Wall, so milk powder and flossy became the secret weapon of Genghis Khan to Europe and Asia. In 1805, the Frenchman Pamantilenwald established a milk powder factory and began to officially produce milk powder. During this period, there were other people who studied the production of milk powder. Some designs used vacuum evaporation cans to concentrate the milk into a cake and then dry the flour. Some designs spread the milk after the initial concentration. On the roller, peel off the thin milk film and then make the powder. However, Zui's good milk powder production method was the spray method invented by American Passy in 1877. In this method, the milk is first vacuum-concentrated to 1/4 of the original volume to become a concentrated milk, and then sprayed into a drying chamber with hot air in a mist, dehydrated to make a powder, and then rapidly cooled and sieved to be packaged. For the finished product. This method is still in use today. Its birth promoted the development of the milk powder manufacturing industry in the early 20th century. In addition, milk powder also refers to fans of Mizuki Nana. Today's mainstream milk powder is divided into milk powder and goat milk powder.

Research data show that water content is one of the important quality indicators of food. A certain moisture content can maintain food quality and prolong food preservation. The water of various foods has their own standards. Sometimes, if the moisture content exceeds or decreases by 1%, It plays a big role in both quality and economic efficiency. For example, the milk powder requires a water content of 3.0 to 5.0%, which cannot exceed this range. If it is 4 to 6%, that is, the moisture content is increased to 3.5% or more, causing the milk powder to agglomerate, the commodity value is low, and the milk powder is easily discolored after the moisture is raised. The storage period is lowered, and some foods are too moist, the tissue state is softened, and the elasticity is also reduced or disappeared. The moisture content of milk powder is too high, which may also cause problems such as loss of nutrients, growth of microorganisms, and deterioration of milk powder. The current industry average is controlled at around 4%. Therefore, testing the moisture content in milk powder is an indispensable item for each company's production and quality inspection.

At present, methods for detecting the moisture content of milk powder include a national standard oven method and a rapid moisture analyzer method. The rapid moisture analyzer adopts the oven method principle, which greatly shortens the detection time, is simple, fast, accurate, and has less sample usage, and thus is more and more widely used.
