Edible baking soda is different from soda (sodium carbonate) and baking soda (sodium bicarbonate) and is an industrial alkali. Baking soda is made from soda solution or crystal after absorbing carbon dioxide. So baking soda is also called edible alkali (powder) in some places Baking soda is solid, round, white and easily soluble in water.
Monosalts are: normal salt, acidic salt and alkaline salt. Sodium bicarbonate is an acid salt produced by neutralization of strong alkali and weak acid, which is weakly alkaline when dissolved in water.
In the mass production of steamed bread, fried dough sticks and other foods, the melted water of baking soda powder is often mixed into noodles, which is decomposed into sodium carbonate, carbon dioxide and water after heating, and carbon dioxide and water vapor overflow, which can make the food more fluffy and sodium carbonate remains in the food. Too much baking soda in steamed bread will taste.
Matters needing attention
1, for the sake of public health, soda water must be drunk in moderation, which varies from person to person. Drinking soda water for a long time may cause alkalosis, manifested as anorexia, nausea, headache, convulsions and even coma, especially for the elderly and patients with kidney disease. In addition, soda water will dissolve the enamel of teeth, which will easily lead to the loss of calcium and increase the obesity rate by 1.6 times.
2. Soda water that has a healthy effect on human body mainly refers to water containing "baking soda", that is, sodium bicarbonate. In addition to gout patients, people with excessive gastric acid secretion can also drink more alcohol to neutralize gastric acid. However, people with low gastric acid secretion should not drink a lot of soda water, otherwise it will aggravate gastric acid deficiency.
3, patients with hypertension had better not drink soda water, because soda water contains more sodium, reducing sodium intake is an important measure to treat hypertension. Healthy people should not drink soda water for a long time, otherwise it will easily lead to excessive sodium in the diet.
Extended data:
Sodium bicarbonate can be directly used as raw material in pharmaceutical industry to treat hyperacidity. It can also be used in film production, tanning, mineral processing, smelting, metal heat treatment and fiber and rubber industries. At the same time, it is used as a detergent for soaking wool and agricultural seeds.
One of the most widely used loosening agents in food industry is used to produce biscuits, cakes, steamed bread, bread and so on. , is the producer of carbon dioxide in soft drinks; It can be compounded with alum to form alkaline baking powder, or with soda ash to form civil caustic soda; It can also be used as a butter preservative. Fire fighting equipment is used to produce acid-base fire extinguishers and foam extinguisher.
The rubber industry uses it in combination with alum and sodium bicarbonate pore-forming agent to play the role of uniform pore-forming and is used in the production of rubber and sponge. Metallurgical industry is used as flux for casting steel ingots.
The machinery industry is used as a molding aid for sand molds of cast steel (sand casting). Printing and dyeing industry is used as fixing agent for printing and dyeing, acid-base buffer and post-treatment agent for fabric dyeing and finishing. Adding baking soda during dyeing can prevent the yarn tube from producing colored flowers. The pharmaceutical industry is used as the raw material of acid-making agent.
Used as analytical reagent, starter in inorganic synthesis, pharmaceutical industry, acidosis treatment and food industry, generator of carbon dioxide in soda and cold drinks, preservative for butter. It can be directly used as raw material of pharmaceutical industry, used as wool detergent, foam extinguishing agent, bathing agent, alkaline agent and filler.
Often used with ammonium bicarbonate as a leavening agent for biscuits and cakes. The addition amount in wheat flour is 20g/kg. Can be mixed with citric acid, tartaric acid, etc. Preparation of foaming agent for solid cold drinks (production of co? )。 Because it is a harmless weak alkaline agent, adding about 0. 1% ~ 0.2% when washing vegetables can make it green and stable.
