The Mid-Autumn Festival is approaching, and a video of a "cotton mooncake" has been circulating online. In the video, a man will be "moon cake" inside the meat fluff filling out with water, said rinse can be seen after the meat fluff is made of cotton, he ate after the stomach is very uncomfortable. The man also exposed the name of the manufacturer of the mooncake and called for the video to be forwarded.
Is the video true? The reporter found that the video is actually in 2017 in Taizhou, Zhejiang and other places circulated old rumors, when the video has been the relevant departments of Taizhou, Zhejiang rumors. The video "moon cake" is actually a local pastry manufacturer of egg yolk pastry, which is chicken meat pine, "cotton meat pine" is a rumor.
Why can't the meat floss be made of cotton? Recently, Zhejiang Taizhou City Market Supervision Bureau and Taizhou Food and Drug Inspection and Research Institute experts, jointly conducted a field experiment, the following experimental process:
The first step: try to eat. The scene were prepared three plates of materials: meat, clean cotton, cotton with soy sauce coloring made of "fake meat". Staff selected cotton and meat pine, respectively, "taste experience". ↓
Conclusion: Meat Loaf is a muscle fiber, the main component of protein, into the mouth a bite will melt, the taste is fluffy. And cotton is plant fiber, the main component is cellulose, an insoluble fiber, although it also looks fluffy, but completely chewy.
Step 2: Microscope observation. Cotton under the microscope picture, the fibers are thin, thick walled, with cell cavities; meat loaf under the microscope picture, the fibers are thicker than cotton fibers, transverse muscle visible. "In fact, the meat pine and cotton directly into the 400 times the microscope, the difference between the two from the visual point of view is very intuitive." The inspector said.
Step 3: Burn it with fire. Dry cotton a little on the spot, shining with the light of the flame, and burning quickly, not long to burn into the ash, there is a pungent smell of clothes being burned. The meat loaf was not easy to ignite, and it took several passes with a lighter to blacken part of it, giving off a distinctly burnt odor, like the smell of burnt meat at home.
Step 4: Reagent experiment. Fiber shredded meat is mainly composed of protein, while the main component of cotton is cellulose, can be experimented by proteolytic digestion and bioconjugate reagent method. Proteolysis experiments simulate the process of digestion in our stomach and intestines, adding protease after 12 hours of resting, meat floss and meat powder floss basically has completed the enzyme digestion, has been mixed into a paste, fluid; while the cotton basically maintains the original shape, basically unchanged.
Double urea reagent method to verify the presence of protein, double urea reagent solution will turn purple when encountering protein, that is to say, encountered meat is purple; but the main component of the cotton inside is cellulose, cellulose is a kind of insoluble dietary fibers, double urea reagent solution will not be changed
