There is no fish in the fish-flavored shredded pork and no pineapple in the pineapple bag. So, is there soda in the soda water?
Current-saving version
1. Soda water contains baking soda (sodium bicarbonate), which can be divided into natural soda water and artificial soda water. The former contains not only sodium bicarbonate, but also various trace elements. The latter is prepared by adding food additives such as sweeteners and food flavors to the aqueous solution of sodium bicarbonate.
2. Drinking soda water properly is beneficial to health, but it is not suitable for patients with hypertension, hyperlipidemia, chronic kidney disease, gastritis with low gastric acid secretion, and healthy people should not drink soda water in large quantities for a long time.
Soda water contains baking soda instead of soda.
Soda water is not water containing "soda", in which "soda" refers to baking soda. Although there is a word difference between baking soda and soda, their chemical properties and application fields are very different.
The chemical name of baking soda is sodium bicarbonate (NaHCO3), also known as sodium bicarbonate and acid sodium carbonate. It is salty and soluble in water, and its aqueous solution is weakly alkaline. It is widely used in daily life, such as making steamed buns with dough, making soda and fire extinguishing agent, kitchen cleaner, removing stains and odor, preventing mildew and so on.
The chemical name of soda is sodium carbonate (Na2CO3), also known as soda ash and alkaline surface. Its aqueous solution is alkaline, irritating and corrosive, which can cause skin and eye burns in direct contact, and digestive tract burns, mucosal erosion, bleeding and shock in case of accidental ingestion. It is one of the important chemical raw materials, which is widely used in light industry, daily chemical industry, building materials, chemical industry, etc., and is widely used in glass manufacturing.
Natural soda water and artificial soda water contain different substances.
Soda water is a kind of drink containing 0.4-0.6 grams of sodium bicarbonate per liter, and its pH value is generally 7.5-9.0, which is weakly alkaline.
Commercially available sodas are divided into natural sodas and artificial sodas. Natural soda water not only contains sodium bicarbonate, but also contains many trace elements, such as boron, zinc, selenium and chromium. Artificial soda water is prepared by adding food additives such as sweeteners and food flavors to sodium bicarbonate aqueous solution. If carbon dioxide is pressed, it becomes "soda water" or "sparkling soda water". In terms of taste, "natural soda water" generally has no obvious taste, but "artificial soda water" adds flavor by adding edible essence.
Proper drinking is beneficial to human body, but it cannot replace boiled water.
Studies have proved that drinking soda properly can relieve the symptoms of indigestion and constipation, neutralize gastric acid, resist oxidation, prevent skin aging and help uric acid excretion. However, soda water is not suitable for all people.
The content of sodium ion in soda water is high, and a high-sodium diet will increase the risk of hypertension and cardiovascular diseases, and will also lead to the deterioration of chronic kidney disease. Therefore, patients with hypertension, hyperlipidemia and chronic kidney disease are not suitable for drinking soda water often. Healthy people should not drink a lot of soda water for a long time, otherwise it will easily lead to excessive sodium intake, which is not conducive to the health of the cardiovascular system.
In addition, soda water can only alleviate the acid reflux caused by excessive gastric acid secretion, and it is not suitable for gastritis patients with too little gastric acid secretion.
The price of soda water is not cheap, not as economical as boiled water. Everyone still chooses boiled water, and soda water is used as a daily taste regulator.
