Besides sodium bicarbonate, natural soda water also contains many trace elements, so it is a good drink. Only a few countries in the world, such as France, Russia and Germany, produce natural soda water. Fanshan trona produced in Leshan City, Sichuan Province, China and Shihanquan brand soda produced in Kedong County, Heilongjiang Province, China are both trona. The source of alkaline water in Ying Ge Yantian is located in the southwest of Yantian, which is a marine sedimentary stratum. Alkaline water is stored in the aquifer at the bottom of the stratum, contacting with the basement granite, with a buried depth of 240 meters and an aquifer thickness of 22.5 meters. The water level of the pumping well is 9.2 meters above the ground and the depth of the well is 8.5 meters. The gravity flow rate is 1.2 16L/S, the water temperature is 36℃, and the salinity is 805 mg/L. The PH value of well water is 7.3 1, the salinity is 2 105mg/L, the na is 522mg/L, and the K is/. Li is 0.3mg/L, and Sr is 0.96 mg/L. From the gushing wellhead, the splashing water shines under the refraction of sunlight, and the stone steps near the well are covered with green moss. This kind of water tastes almost as natural as soda water on the market. Natural soda water is rich in plasma minerals and trace elements such as boron, zinc, selenium and chromium, which are in ionic state and are more easily absorbed by human body.
2 Basic characteristics

Carbonated water (English: Carbonated Water), also known as soda water (Cantonese transliteration of soda water), is water with dissolved carbon dioxide. The process of dissolving carbon dioxide is called carbonation. The chemical formula of carbonic acid is H2CO3. Carbonated water is produced by a natural gas soaking mineral water company in Salz, Germany. They put water in a bottle and then add sodium bicarbonate to make water. According to the amount marked on the carbonated water bottle produced by the soda club, it is also made of a small amount of salt, sodium citrate, sodium bicarbonate, ammonium bicarbonate, potassium sulfate or phosphate. These additives make carbonated water slightly salty.
Joseph priestley, an English chemist, was the first person to discover the method of making carbonated water. In a brewery in Leeds, he put a bowl of water in a place above the beer barrel. After that, carbon dioxide and nitrogen cover the water bowl on the fermented beer barrel. At that time, people mostly used carbon dioxide and nitrogen to kill rats. Joseph priestley was surprised that the water tasted better after adding gas, so he offered carbonated water as a refreshing drink to his friends. 1772, joseph priestley published a book, The Combination of Water and Gas, which described that dropping sulfuric acid on chalk would release carbon dioxide and encouraged people to collect gas in a bowl filled with water.
Soda (3) 177 1 year, Swedish chemist Ruben Begemann independently invented a manufacturing process similar to that of joseph priestley who discovered carbonated water. But it was not very successful. He managed to replicate the natural bubbling spring water, which was considered healthy at that time. Carbonated water is made of pressurized carbon dioxide through water. Compared with the standard atmospheric pressure, the pressurization pressure increases the solubility and makes more carbon dioxide dissolve. When the bottle cap is opened, the pressure is released and the gas forms bubbles, thus forming unique bubbles.

Carbonated water is most famous for removing stains, such as coffee stains in coffee cups or silver stains. It is said that wine stains can be mixed with salt and then removed by adding a large amount of carbonated water. There are all kinds of groceries in carbonated water, and the production is very simple. Buy baking soda at the condiment counter in the supermarket. Then prepare a bottle of mineral water. Put a spoonful of baking soda in the glass. The dosage of baking soda can be determined according to personal taste. If it's too much and salty, some people can't stand it, so put less. Then fill it with mineral water to make sure the water is cold. The standard of living is good. Eating big fish and meat and drinking soda water every day can neutralize the acid-base balance in the body and be beneficial to health. Drink once or twice a week and stick to it, and your body will feel particularly cool.
Homemade French soda water
It can be formed naturally or artificially by weak alkali effervescent tablets, soda effervescent tablets and machines. There aren't many materials for making soda: condensed milk, I like Shouxinggong brand or Huoquan brand; Soda water, recommended Canadian dry soda water; ; Raw eggs; And crushed ice. The mixing of soda water is simple: dig a tablespoon of condensed milk, beat a raw egg, pour a cup of soda water and mix well, then put a thick layer of crushed ice. The drink is white, as white as the ancient Greek goddess holding the flame, which is fascinating; There is a small bubble around the soda.
Five main uses
edit
There are more and more kinds of drinks on the market, but the ingredients and nutrition of all kinds of drinks are different. Here we will analyze the ingredients of common concentrated drinks on the market, so that you can have a certain understanding of the drinks when you buy them.
Carbonate Beverages
A beverage in which carbon dioxide is pressed into pure drinking water and sweeteners and spices are added. Among them, it is divided into: fruit juice, that is, carbonated drinks (such as orange juice soda, pineapple soda, etc. ) the content of raw juice is not less than 2.5%; Fruit-flavored carbonated drinks (such as orange soda and lemonade). Using edible essence as flavoring agent, the content of raw juice is less than 2.5%; Coke-type carbonated drinks (such as Coca-Cola soda) contain coke, lemon, laurel and essence, and are mixed with caramel or other spicy fruits; Other types of carbonated drinks other than the above three types (such as soda water, salt soda water, etc.). This drink contains almost no other nutrients except glycogen. Because it contains carbon dioxide, it can help digestion, promote the discharge of hot air in the body, produce a sense of coolness, have a certain bactericidal effect, and can also replenish water.
fruit drink
Fresh or frozen fruits with moderate maturity are used as raw materials, and fruit juice or mixed fruit juice products are obtained by mechanical processing, or products obtained by adding ingredients such as sugar liquid and sour agent. The finished product can be drunk directly or diluted. This kind of beverage is also divided into raw juice, fresh juice, concentrated juice and juice syrup. Fruit juice beverage is an ideal beverage with rich nutrition and easy digestion, and because it is rich in organic acids, it can stimulate gastrointestinal secretion and help digestion, and also make the upper part of the small intestine acidic, which is helpful for the absorption of calcium and phosphorus. However, because the juice contains a certain amount of water, it is unstable and easy to ferment and mold. Therefore, special attention should be paid to the shelf life and storage conditions of such drinks, and only those that meet the hygienic quality can be drunk.
Fresh vegetable juice
Adding salt or sugar to one or more kinds of fresh vegetable juice (or refrigerated vegetable juice) and fermented vegetable juice, degassing, homogenizing and sterilizing to obtain various vegetable juice products with certain nutrition.
Milk beverage
Comprises the following steps: (1) taking fresh milk or dairy products as raw materials, adding sugar, fruit juice (or water, cocoa, coffee), edible essence, coloring agent and other ingredients to obtain a milk beverage; (2) Fresh milk or dairy products are fermented by lactic acid bacteria or yeast, added with sugar, edible essence and other ingredients to make paste or liquid products, and diluted with water as raw materials.
Plant protein
Soybean is purified, ground, deslagging, added with flavoring agents (sugar, milk, coffee, cocoa, fruit and vegetable juice, coloring agent and edible essence), then sterilized, deodorized and homogenized. Because it contains nutrients such as plant protein, it has the unique flavor of soybean milk products.
Natural mineral water: it meets the relevant requirements and sanitary quality standards, and has a beautiful flavor and unique palatability when drinking. It contains trace elements such as iron, copper, zinc, iodine, manganese and fluorine, which are beneficial to human body. Some harmful elements contained in mineral water need to be treated and removed to meet the requirements of national standards before they can be put on the market. Recently, purified water and distilled water on the market are water drinks different from natural mineral water: hygienic standard.
sports drink
This is a drink developed for exercise, which can supplement sodium, potassium, magnesium and carbohydrates lost by strenuous exercise and sweating, and relieve the consumption caused by fatigue and body temperature rise. This drink is also suitable for high-intensity work and people who sweat a lot in hot summer.
Solid beverage
Sugar (or without sugar), fruit juice (or without fruit juice), plant extracts and other ingredients are used as raw materials, which are dissolved and processed into powder, granule or block products for drinking. Such as instant coffee, malt extract, chrysanthemum products, summer mulberry chrysanthemum extract, herbal tea solid beverage, etc. This beverage is easy to carry, suitable for storage, simple to take and unique in flavor.
liquor
More common are beer and sparkling wine (with alcohol content of 3-5). Beer is divided into draft beer and cooked beer. Beer is a beverage with malt as the main raw material, rice, millet and other auxiliary materials, and hops added, which is fermented by yeast. Because malt is rich in protein, it can be directly absorbed after saccharification into amino acids; Sugar fermentation produces alcohol and carbon dioxide, which helps digestion and helps the body dissipate heat; Hops have antibacterial, diuretic and sedative effects.
Other drinks
Such as health drinks (mainly fortified nutrients and other substances), tea drinks (including all kinds of herbal tea drinks), herbal tea drinks (such as Xia Sangju and Wang Laoji drinks) and various cold drinks, etc. The development of beverages is changing with each passing day, and there are many varieties. There is also an effervescent tablet called weakly alkaline water or weakly alkaline water, which can also be dissolved in water to become weakly alkaline water or weakly alkaline water.

Can't change the human body's pH and acidic constitution.
It is known that the pH value of normal blood is between 7.35 and 7.45, which is weakly alkaline. The stability of this pH value is called acid-base balance. If we want to know whether soda can improve acidic constitution, we must first find out whether the pH value of human blood will change with the pH value of the drinks we drink.

Li Duo explained that after a healthy person drinks water, the water enters the intestine through the stomach (the pH value of gastric juice is 0.9 ~ 1.5, which is acidic), and then most of it is absorbed in the intestine (a small amount is absorbed in the stomach). The whole process includes the replacement and transport of anion and cation, the adjustment of pH value, the excretion of metabolites and the absorption of nutrients. The kidneys and intestines themselves regulate the acid-base to maintain the acid-base balance in the body [1].
"The gastrointestinal tract will quickly adjust the pH value of weakly alkaline soda water entering the body to the pH value of the internal environment of the body through its own adjustment function." Li Duo stressed that drinking soda water, ordinary mineral water, cold boiled water, etc. It will not change the pH value of human body, let alone the acidic constitution.
"At present, there is no evidence that drinking soda water in normal healthy people has the effect of health care and balancing the pH value in the body." He added.
