He thinks that 200 yuan is a bit of a loss and may not be able to eat it back. So he put the fish skin in hot water and scalded it. Unexpectedly, the fish skin disappeared instantly and melted in hot water, leaving only a layer of "oil skin".
Netizens saw this scene and talked about it. Some netizens speculated that it might be made of edible gum, and some netizens said that alkaline substances were added to the fish skin of cold dishes, so that the processed fish skin would be thicker and more appetizing. Just blanch the fish skin with hot water and alkali and it will melt.
Some netizens also said that because fish skin contains a lot of vitamins and collagen. Collagen contained in fish skin is arranged in macromolecular structure. Macromolecular structure is characterized by strong permeability. The disadvantage is poor stability. Anyone who has studied physics knows that the higher the temperature, the faster the molecules move. So when the speed of the molecule exceeds the structural stability point of the molecule, It will expand, and cells are made of molecules, so molecules will expand and penetrate the cell wall. The structure of the cell will collapse. The concrete result is shrinking and getting smaller and smaller.
This also triggered a heated discussion among netizens. Many people think it's a bit too much. Fish skin consists of collagen and polysaccharide, which will melt when heated. This is common sense.
Some netizens also said that the current businesses are invincible, only what you can't think of, and there is nothing they can't do. For example, adding alkaline substances to the fish skin of cold dishes will make the fish skin thicker after processing and make people more appetizing. Just blanch the fish skin with hot water and alkali and it will melt.
Some netizens said that fish skin is made of edible gum, and these guessing experts also said that with the explosion of some controversial videos, it is still good to make consumers pay more and more attention to food safety, and at the same time, it can spur businesses, but there is no need to be so scared in specific life. Pay attention to the channels of purchasing ingredients, don't be greedy and cheap, and eat too much takeaway. In fact, it can be well prevented.
