Soda water, also known as alkaline water, is a weakly alkaline drink, often added sweeteners and flavors of the drink, there are no added sweeteners on the market soda, the following hazards described below are mostly artificial sweeteners and flavors intake of excessive harm. It is an aqueous solution of sodium bicarbonate, which is weakly alkaline and can be used externally to disinfect and sterilize. Sodium bicarbonate is what we call baking soda, also known as pasta starter, with the molecular formula NaHCO3? But this is not a direct addition to the noodle starter, most of the soda sold on the market is a synthetic carbonated beverage with carbon dioxide pressed into purified drinking water and sweeteners and flavors added. Baking soda: NaHCO3 soda: NA2CO3, weakly alkaline. Soda is actually carbonated water, and Coca-Cola is a representative of carbonated beverages. Pure soda water is also available, usually in bottles, supermarkets have to sell. It can be used to make cocktails. You can go to the drugstore to buy baking soda tablets with warm water, but the concentration is not easy to grasp. Generally used to disinfect the soda is appropriate to use 0.4% In addition, and then add to help you understand more thoroughly.

Natural soda contains sodium bicarbonate in addition to a variety of trace elements, so it is a good drink. Only a few countries in the world, such as France, Russia and Germany, produce natural soda. Domestic market sales of China's Sichuan Province, the city of Leshan City, produced by the Fanshan natural soda water and China's Heilongjiang Province, Kedong County, produced by the Shihanquan brand of soda water are natural soda water. The source of alkaline water for Yinggehai Salt Farm is located in the southwestern area of the salt farm, which is a marine sedimentary stratum. Alkaline water is stored in the aquifer at the bottom of the stratum, in contact with the base granite, at a depth of 240 meters, with a thickness of 22.5 meters of the aquifer. The water level of the machine well is 9.2m above the ground and 8.5m deep, with a self-flow rate of 1.216L/S, water temperature of 36°C, and mineralization degree of 805mg/L. The PH value of the well water is 7.31, with mineralization degree of 2105mg/L, Na 522mg/L, potassium 16.7mg/L, magnesium 7.78mg/L, boron 5.54mg/L, lithium 0.3mg/L, and strontium 0.96mg/L,. Mineralization 1478mg/L. Spouting out of the wellhead, splashing water in the refraction of the sunlight bright crystal, wells next to the stone steps, turquoise moss spread all over the ground. The taste of this water is almost as natural as the commercially available sodas. Natural soda water is rich in boron, zinc, selenium, chromium and other ionic minerals and trace elements, these trace elements are ionized, more easily absorbed by the body.

4Production process

Edit

Carbonated water (English: Carbonated water), also known as soda water (soda water Cantonese transliteration), is water in which carbon dioxide has been dissolved. The process of dissolving carbon dioxide is called carbonation. The chemical formula for carbonic acid is H2CO3.Carbonated water is produced by a gas-foamed mineral water company in Seltzer, Germany, who make it by putting water into bottles and adding sodium bicarbonate. Soda Club carbonated water is also made with small amounts of table salt, sodium citrate, sodium bicarbonate, ammonium bicarbonate, potassium sulfate, or phosphate, depending on the amount of carbonated water labeled on the bottle, and these additives give the carbonated water a slightly salty taste.

Joseph Priestley, a British chemist, was the first person to discover how carbonated water was made. He put a bowl of water in a place above a keg in a brewery in Leeds. After that, two gases, carbon dioxide and nitrogen, covered the bowl of water on top of the fermenting beer barrel. At that time, carbon dioxide and nitrogen were mostly used to exterminate rats. Joseph Priestley could not imagine that water would have a more pleasant taste with the addition of gas, so he offered carbonated water as a refreshing drink for his friends.In 1772, Joseph Priestley published a book, The Combination of Water and Gas, describing the release of carbon dioxide from drops of sulphuric acid on chalk, and encouraging people to collect the gas in bowls filled with water.

Soda (3) In 1771, Swedish chemist Luben Bergmann independently invented a manufacturing process similar to the way Joseph Priestley discovered how to make carbonated water. However, it was not very successful and he managed to reproduce naturally bubbling spring water, which was then considered to be beneficial to health. Carbonated water is made by passing pressurized carbon dioxide through water. The pressurized pressure is stronger than standard atmospheric pressure, which increases its solubility and allows more carbon dioxide to dissolve. When the cap is opened, the pressure is released and the gas forms a bubble that comes out, creating a unique effervescence.

Carbonated water is best known for its benefits in removing tarnish, such as coffee stains in coffee cups, or silver tarnish. Wine tarnish is said to be removed by mixing in table salt and then adding a large amount of carbonated water. Carbonated water is available at grocery stores and is very easy to make. Buy baking soda from the condiment counter at the supermarket. Then prepare a bottle of mineral water. Put a spoonful of baking soda in a drinking glass, the amount of baking soda can be determined according to personal taste. If you put too much, too salty, some people can not stand, put less. Then pour full of mineral water, pay attention to the water must be cold. Good standard of living, every day, eat meat and fish, drink soda water can neutralize the acid-base balance in the body, good for health. Drink once or twice a week, stick to it, the body will feel extra cool.

Homemade French soda

Can be formed naturally or artificially generated with weak alkaline effervescent tablets, soda effervescent tablets and machines. There aren't a lot of ingredients to make French soda: condensed milk, I like Shouxing Gong or Living Springs; Club Soda, Canada Dry Club Soda is recommended; raw eggs; and crushed ice. Mixing a club soda is easy: scoop a tablespoon of condensed milk, crack a raw egg, pour a cup of club soda and stir, then top with a thick layer of crushed ice. The drink is snow-white, as white as the ancient Greek goddesses holding up the sacred fire, and the soda is rimmed by a ring of tiny bubbles that pop and pop.

5 main uses

Edit

The market is becoming more and more types of beverages, but a variety of beverages contain different ingredients and nutrients, the following market for the common concentration of beverages to analyze the ingredients, so that you have a certain understanding of the beverage when you buy.

Carbonated beverages

Pressing carbon dioxide into purified drinking water and adding sweeteners and flavors to the beverage. Which is divided into: fruit juice type, that is, the original fruit juice content of not less than 2.5% of carbonated beverages (such as orange juice soda, pineapple soda, etc.); fruity type, with edible flavors for the fragrance, the original fruit juice content of less than 2.5% of carbonated beverages (such as orange soda, lemonade soda, etc.); cola type, containing cola, lemon, laurel, flavoring, and caramel-colored or other similarly pungent fruity aroma of the mixture of aromas of carbonated drinks (such as) Coca-Cola soda); Other types, carbonated beverages other than the above three types (e.g., soda, salt water, etc.). These beverages have little or no nutrients other than glycogen. Because of the carbon dioxide, can help digestion, and can promote the body heat discharge, produce a cool and refreshing feeling, and has a certain bactericidal function, can also be supplemented with water.

Juice drinks

Fruit juice or mixed fruit juice products obtained by mechanical processing with moderately ripe fresh or frozen fruits as raw materials, or by adding sugar, acidifier and other ingredients obtained products. The finished product can be consumed directly or diluted to drink. This type of beverage is also divided into the original juice, fresh juice, juice concentrate and juice syrup. Fruit juice is rich in nutrients, easy to digest the ideal beverage, and because of the rich organic acids, can stimulate gastrointestinal secretion, digestion, but also can make the upper part of the small intestine is acidic to help the absorption of calcium and phosphorus. But also because the juice contains a certain amount of water, unstable, easy to ferment, mold, so pay special attention to the shelf life of such drinks and preservation conditions, in line with the quality of health before drinking.

Fresh vegetable juice

One or more kinds of fresh vegetable juice (or refrigerated vegetable juice), fermented vegetable juice add salt or sugar and other ingredients, after degassing, homogenization and sterilization of various vegetable juice products, with a certain degree of nutrition.

Milk beverages

including ① fresh milk or dairy products as raw materials, add sugar, fruit juice (or water, cocoa, coffee), food flavors and coloring agents and other ingredients to get the milk beverage; ② fresh milk or dairy products with lactic acid bacteria or yeast fermentation, add sugar, food flavors and other ingredients and the paste or liquid products, and as a raw material for the dilution of the beverage with water.

Vegetable Protein

Soybeans are purified, milled, and de-residued, and beverages are made by adding (or not adding) flavor agents (sugar, milk, coffee, cocoa, fruit and vegetable juices, coloring agents, and food flavors), and then sterilized, deodorized, and homogenized. Because it contains plant protein and other nutrients, it has the characteristic flavor of soy milk products.

Natural mineral water: in line with the relevant requirements and health quality standards, drinking flavor is beautiful, unique sense of palatability. Containing beneficial trace elements such as iron, copper, zinc, iodine, manganese, fluorine and so on. Mineral water contains some harmful elements need to be removed after treatment, in line with national standards before being allowed to go on sale. Recently on the market pure water and distilled water is with natural mineral water: health standards are different from the water beverage.

Sports drinks

This is for sports and the development of a drink, can supplement the body due to intense exercise and sweating lost sodium, potassium, magnesium and carbohydrates, moderate fatigue and body temperature rise caused by the consumption. This drink is also suitable for labor-intensive work, as well as hot summer work sweat more personnel.

Solid beverages

Sugar (or no sugar), fruit juice (or no juice), plant extracts and other ingredients as raw materials, processed into powder, granular or block by dissolving the drinkable products. Such as instant coffee, cream of wheat, chrysanthemum, chrysanthemum products, and herbal tea solid drinks. These drinks are easy to carry, suitable for preservation, easy to drink, unique flavor.

Alcoholic beverages

More common are beer and sparkling wine (with 3-5 degrees of alcohol) and so on. Beer is divided into fresh beer and cooked beer. Beer is a beverage made from malt as the main raw material, rice, millet and other auxiliary materials, adding hops, by yeast fermentation. Because malt is rich in protein, after glycation into amino acids, which can be directly absorbed; sugar fermentation to produce alcohol and carbon dioxide, which helps digestion and helps the body to disseminate heat; hops have antibacterial, diuretic and sedative effects.

Other beverages

such as health drinks (mainly fortified with nutrients and other substances), tea beverages (including various types of cold tea drinks), herbal tea drinks (such as Xiasangju, Wanglaoji type of drinks), and various types of cold beverages and so on. Beverage development is rapidly changing, and there are many varieties. There is also a kind of water called weak alkaline water or weak alkaline water effervescent tablets can also be dissolved in water to become weak alkaline water or weak alkaline water.

Can not change the human body pH and acidic body

Normal human blood pH is understood, the normal human blood pH range is 7.35 ~ 7.45, weak alkaline, the stability of this pH phenomenon is called acid-base balance. In order to know whether soda can improve the acidic body, we must first figure out whether the pH value of human blood will change with the pH value of the ingested beverage.

Lidow explained that after a healthy person drinks water, it passes through the stomach (the pH of gastric juice is 0.9 to 1.5, acidic) into the intestines, and then most of it is absorbed in the intestines (a small amount is absorbed in the stomach). The whole process involves the replacement of anions and cations, transport and pH regulation, excretion of metabolites, and absorption of nutrients. The kidneys and intestines themselves regulate acid-base to maintain acid-base balance in the body [1].

"The gastrointestinal tract, through its own regulatory function, will quickly regulate the pH of the weakly alkaline soda that enters the body to the pH of the body's internal environment." Li Duo emphasized that no matter drinking soda, or ordinary mineral water, cold boiled water, etc., will not change the body's pH, let alone change the acidic body.

"At present, there is no evidence to prove that drinking soda water in normal healthy people has the effect of health care and balancing the pH level in the body." He added.
