Q: Why does not the base noodles rub?: Yes, you are not practicing

Q: How does the edible base use?: (Sodium carbonate) (chemical formula Na2CO3) and baking soda (sodium bicarbonate) (chemical formula NaHCO3), baking soda is made from soda ash solution or crystal absorption of carbon dioxide after the finished product, both There is no difference between the system. Therefore, edible alkali in some places also known as baking soda (powder). Edible alkali is solid state, round, color white, soluble in water.

Q: What is the difference between baking base and common base?: The aqueous solution of the two is worse. Do German or use the baking base, I have tried, not only different colors, taste and taste are also significantly different.

Q: What is the important character of Chinese made alkali?: In 1862, the Belgian people Solvay (Ernest Solvay 1838-1922) invented the salt, ammonia, carbon dioxide as raw material for the production of sodium carbonate "Solvay alkali method" (also known as the ammonia method). Since then, Britain, France, Germany, the United States and other countries have established a large-scale production of soda ash plant, and organized the Saul Wei Association, members of the country outside the implementation of technical blockade.

Q: Our home often burn porridge which put a little alkali inside, so delicious, more entrance, eat often harmful to the health of it?: Harmful stomach

Q: Would you like some rice when you cooked rice or millet gruel?: But there is a situation, that is, in the boiled polenta, corn paste, the production of Wo Wo first corn products, should add a small amount of alkali. This is because the corn contains niacin is very high, but there are 63% to 74% can not be absorbed by the body combined with niacin, long-term consumption of this corn food may occur niacin deficiency - podular disease: dermatitis , Diarrhea and dementia. Early symptoms include lazy weakness, loss of appetite, chapped lips, tongue swelling and pain. If the disease continues to develop, will make the skin in the sun dermatitis, face, hands and feet skin will appear red, long blisters, peeling, brown pigmentation, rough and wrinkles and other symptoms. In order to avoid this situation, the best way is to add some alkali in the corn food, that is, in the boiled polenta, corn batter, do Wo head, the amount of some alkali. This can make the combination of corn in the release of niacin released into a free niacin, alkali-added corn food generally niacin release rate of up to 37% to 43%, and also save vitamin B1 and vitamin B2, very It is good.

Q: That day, I put the alum in the water, and then I smell the gas, I would like to know the alkali is not harmful to people, right?: Alkali has a strong role in degreasing, you can remove the oil on the dry goods on the excess oil;

Q: The commonality of the base: alkaline solution can react with salt, generate new alkali and new salt

Q: What is the harm to the human body?: Should be appropriate. Alkali, destruction of vitamins, but also a combination of some toxins, if too much intake of alkaline food, will be harmful to the body, easy to damage the absorption of vitamins, sepsis patients, is not conducive to good health!

Q: What is alkali?: What is the alkali is the ionic compound, the ionization of the anion is hydroxide (OH-), in fact, the oxygen ion acid root (which can compare sulfur and sulfur), and the anion contains only hydroxide. (Such as LiOH, NaOH, NH3 · H2O) soluble in water, alkaline earth metal ions formed in the periodic table from top to bottom gradually soluble [Be (OH) 2, the alkali metal ions or alkali ions, Mg (OH) 2 is insoluble, Ca (OH) 2, Sr (OH) 2 is slightly soluble, and Ba (OH) 2, Ra (OH) 2 is easily soluble, and other bases are in addition to TlOH and Tl (OH) Is difficult to dissolve alkali and acid metathesis reaction is also known as neutralization reaction, that is, H + + OH- == H2O
