Why is the self heating neck band spicy on the neck, is there capsaicin, is it a chemical?

The spiciness of the self-heating neck band on the neck may be due to the fact that it contains capsaicin, which is the active ingredient found in chili peppers. Capsaicin can invigorate blood circulation and remove blood stasis, and when used in certain protective gears, it can produce a sensation of heat, play a role in soothing muscles and promoting blood circulation.

Although capsaicin is an all-natural extract, its chemical properties are not stable and it is susceptible to oxidation. Therefore, during the manufacturing process of protective gear, some chemical treatment may be required to maintain its stability.

In addition, some self-heating gears may not contain capsaicin, but use other chemicals such as clay, tourmaline, etc. to produce thermal effects. When pressed or rubbed, these substances emit a small amount of electric current that excites the body's bioelectricity, which creates a sensation of heat.

It should be emphasized that whether it is a self-heating protective gear containing capsaicin or other ingredients, it should be purchased from regular channels with quality assurance. If in any doubt about the composition or use of the protective gear, it is recommended to discontinue use and consult a medical professional or health professional.

Now there are too many self-heating protective gear on the market, and there are many fakes, so you should be careful when buying and buy carefully, because the real production of self-heating will be tested by the relevant national departments, and there should be a test report, so you must look for ** Self-heating ** are due to the tourmaline coating points on the self-heating protective gear work, those coating points are the tourmaline grinding and processing coating on the protective gear, ** not chili powder, In order to save costs, counterfeit products use capsaicin as a raw material, so don't covet these self-heating protective gear when you buy cheap products with no guaranteed quality. Thank you Hope it helps

It's your ** at the beginning, it's okay to slowly feel very hot, very spicy feeling, take down the piece is red, it's that you're allergic, or hot, you just can't eat it so hot, understand, stop and wait for it to look at it again, and then there is that you can't always rub it.

Coating iron knives with lard prevents them from rusting.

The fish bones will become soft when they are put in vinegar and will continue to pull.

(1) Rice, flour, etc. are rich in starch, starch belongs to sugar, starch-rich foods include noodles, steamed buns, etc

Version 2) When acrolein is completely burned in the air weight, carbon dioxide and water are generated, and the chemical equation of the reaction is: 2C3H4O+702

Ignite6c02+4h2o；Molar mass refers to the mass of a substance per unit of substance, the relative molecular mass of acrolein is 56, so the molar mass of acrolein is 56g mol; An acrolein molecule contains 3 carbon atoms, then 2mol of acrolein molecule contains 2mol 3=6mol of carbon atoms; 1mol of any substance contains a molecule, so 2mol of acrolein contains 2mol of carbon atoms; Let the amount of carbon dioxide produced during complete combustion be x, and from the chemical equation of the reaction, then 2:6=2mol:x, x=6mol

Therefore, the answer is: (1) noodles, steamed buns, etc. (reasonable);
