Study: The Residual Time Of Food Is Closely Related To The Fabric.

hotpot has always been a favorite food choice for people, but the taste of the residual food after eating hot pot is also a great distress for people. The clothes and hair are full of hot pot flavors. Some people find that compared with before, now the "a href=" //www.sjfzxm.com/news/list.aspx Classid=101112107101 "chafing dish flavor" /a "seems to be getting heavier and heavier, often scattered for a few days. Recently, a chef broke the news that the flavor of hot pot is getting heavier and heavier because of the use of additives in hot pot. How does this hot pot taste come from? Is it harmful to human body? Experts say in an interview that judging from the taste and the surface, it is difficult to determine whether the additive is used in the hot pot. In addition, the quick and slow flavor is also related to other factors such as the material of the clothes. 
 it is difficult to tell whether the hot pot contains additives by odor alone.
 Dong Jinshi, Secretary General of the International Food Packaging Association, explained that in theory, the color and taste of some natural foods do not have a strong degree of firmness. Similarly, the taste of natural foods tends to volatilize and is easier to decompose in the human body. Some synthetic ingredients are often difficult to decompose in the air, and relatively long residual time. 
 if it is distinguished by smell alone, it is hard to ascertain that there must be some additives. But generally speaking, the hot pot with strong smell and strong smell is not recommended. But on the other hand, the duration of the hot pot remains related to the material of the clothes and the time of people staying in the hot pot shop.

 experiments have found that the duration of the hot pot's clothes on clothing is also related to the material of the clothes. Under the same pots, the smell of cotton clothing is relatively slow. Taking the spicy hot pot as an example, it is found that the chiffon garments can disperse the flavor in about 1 hours, while the cotton garments need more than 2 hours. For this reason, Gong Yan, an associate professor of the school of materials at Beijing Institute Of Fashion Technology, explains that the length of the dispersal is related to the material of the clothes. The more porous the fabric is, the stronger the adsorption. Taking fiber material as an example, the absorbability of cotton clothing is stronger than that of chemical fiber clothing, and the coating clothing (such as raincoat, assault clothing, etc.) has poor adsorbability, while the adsorption properties of < a href= "//www.sjfzxm.com/news/list.aspx Classid=101112107102" > sweater < /a > are relatively strong, and the residual time of flavor will also be longer. 
 How did the hot pot go to the clothes? What are the principles of removing the chafing dish flavor? The reporter interviewed Yan Xin, a graduate student in polymer chemistry at East China Normal University. He told reporters that the various flavors in the chafing dish (mainly spices) were brought to the air by the steam generated when the pot was boiling, so the whole house was full of chafing dish and the clothes were not spared. 
 the use of lemon water to remove chafing dish flavor is actually a kind of flavor to cover another flavor. Because lemon juice contains citric acid, citric acid and other substances with strong aroma, when its flavor exceeds the flavor left by hot pot on clothes, it can cover up the flavor of hot pot. This is why the effect of 5 drops of lemon juice in the experiment is not good, and the effect is obviously improved when the concentration of lemon essence is very high. Yan said that the main ingredient of the hotpot is amine, which is easy to be reacted by acid lemonade, so that it can be established in theory but lacks experimental support. 
 steam fumigating machine is used to fumigate clothes that are dyed with a pot of fire. Yan Xin says that in a wording of a martial arts novel, this is "treating the human body with his own way". The hot pot flavor is carried to the clothes by steam, and now the water vapor is used to remove the smell. As long as time is enough and fumigation is uniform enough, the smell of hot pot on clothes will dissipate. If you change the hanging machine into a steam iron, if you put a towel underneath the clothes, the hot pot will be carried to the bottom towel by steam. 
 as for the use of electric hair drier on plastic bags, it is hoped that the hair dryer will form a stronger airflow in the pocket, so that the smell of the clothes will be carried out in the accelerated flow of the air. Yan Xin thinks this method is more effective.
