Sparkling water with MSG,,,,,,。 ，，，。。。。。。。。。？

Soda water is weakly alkaline due to hydrolysis. The reaction is not obvious.

In an alkaline environment, MSG undergoes a chemical reaction to produce a substance called disodium glutamate.

Glutamic acid + base – monosodium glutamate.

Monosodium glutamate + base – disodium glutamate.

Acidic or alkaline foods should not be added to monosodium glutamate. Cooking MSG under alkaline conditions will cause a racemic effect, which will reduce the umami taste of MSG; Under acidic conditions or when heated at the same time, pyrrolidoneylation occurs and becomes pyroglutamic acid, which not only reduces umami but is harmful to the human body.

Glutamate is a ubiquitous amino acid: the body produces glutamic acid, which is mainly found in a complexed state in protein-rich foods such as mushrooms, kelp, tomatoes, nuts, legumes, meat, and most dairy products. Glutamate in some foods is present in free form; And only this free-form glutamate is able to enhance the umami taste of food.

Tomatoes, fermented soy products, yeast extracts, certain sharp cheeses, and fermented or hydrolyzed protein products such as soy sauce or soy sauce can be flavored in part due to the presence of glutamate.

MSG manufacturers use selected strains of micrococcus glutamate to produce glutamate in culture media. These bacteria are selected for their ability to secrete glutamate. After that, glutamic acid is isolated from the liquid medium, purified, and made into its sodium salt, monosodium glutamate.

There are two main types of sparkling water in the market, with different recipes.

1. It is natural soda, which is a weak alkaline water containing a variety of minerals, trace elements and sodium bicarbonate;

2. It is soda, that is, synthetic soda, which is mainly made by pressing carbon dioxide into pure water and adding sweeteners and spices.

From a medical point of view, the weak alkalinity of sparkling water does have certain health benefits, which can alkalize urine, thereby promoting the dissolution of uric acid, and can relieve gout to a certain extent. It also neutralizes stomach acid, which is beneficial for relieving stomach acid symptoms.

The following 3 points should be noted before drinking:

Clause. 1. Soda contains sodium bicarbonate, an important ingredient in which excessive intake of sodium ions is not conducive to the health of patients with hypertension, hyperlipidemia, chronic kidney disease, etc., and people with such diseases should try not to drink it.

Clause. 2. Patients with gastritis who secrete too little gastric acid should drink less, or even not drink, so as not to cause stomach discomfort or aggravate stomach problems.

Clause. 3. Healthy people should also not drink a large amount of soda for a long time, otherwise it is easy to cause excessive sodium in the diet, which is not conducive to cardiovascular health.

Carbonated water, also known as soda, is water that has been dissolved into 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 sparkling mineral water company in Seldez, Germany, who put the water in a bottle and then add sodium bicarbonate to make it. According to the amount indicated on the carbonated water bottles produced by the Soda Club, small amounts of table salt, sodium citrate, sodium bicarbonate, ammonium bicarbonate, potassium sulfate or phosphate are also used, and these additives give the carbonated water a slightly salty taste.

British chemist Joseph Priestley was the first person to discover how to make carbonated water. He was in a brewery in Leeds, where he placed a bowl of water on top of a beer keg. Two gases, carbon dioxide and nitrogen, then cover the water bowl on the fermented beer barrel.

At that time, carbon dioxide and nitrogen were mostly used to kill rats. Joseph Priestley did not expect that water would taste more pleasant when gas was added, so he offered a friend carbonated water as a refreshing drink.

In 1772, Joseph Priestley published a book, The Combination of Water and Air, which described the release of carbon dioxide by dripping sulfuric acid on chalk and encouraged people to use bowls filled with water.

Collect gases. In 1771, the Swedish chemist Luben Bergmann independently invented a manufacturing process similar to the method of making carbonated water discovered by Joseph Priestley. But less successfully, he managed to reproduce the naturally bubbling spring water, which at the time was considered to be good for health. Today, carbonated water is made from pressurized carbon dioxide through water.

The pressurized pressure is stronger than the standard atmospheric pressure, which increases solubility and allows more carbon dioxide to be dissolved. When the cap is opened, the pressure is released and the gas forms a foam, creating a unique bubble.

Carbonated water is best known for its benefits for removing smudges, such as coffee stains in a coffee cup, or smudges on silver. Wine stains are said to be removed by mixing table salt and then adding plenty of carbonated water.

MSG and baking soda have comparable solubility in water, and alkali is the strongest.

The main ingredient of edible alkali is sodium carbonate, and 100 grams of water can dissolve grams of sodium carbonate.

The main ingredient of monosodium glutamate is monosodium glutamate, and 100 grams of water can dissolve 10 grams of monosodium glutamate.

The main ingredient of baking soda is sodium bicarbonate, and 100 grams of water can dissolve 10 grams of sodium bicarbonate.

In general, sodium chloride is more soluble in water than sodium bicarbonate. The main ingredient of table salt is sodium chloride, sodium bicarbonate is commonly known as baking soda, first take a look at the solubility table of these two substances, it can be seen from the table that the solubility of sodium chloride is relatively large.

In addition to sodium bicarbonate, natural sparkling water also contains a variety of trace elements, and the formula depends on each manufacturer.

What are the ingredients in sparkling water? You buy a bottle of soda, which has a description of the ingredients on it, and you can just look at it. If you drink soda, it's best to drink the sugar-free one.

The ingredients for sparkling water are water and a small portion of baking soda, followed by some flavors and sugar.

Buy baking soda, and if you can't find it, you can replace it with medical sodium bicarbonate tablets.

2.Second, prepare the right honey for later use.

3.Prepare 500 ml of water, grams of sodium bicarbonate and a spoonful of honey, put it in a bottle and shake well.

The main ingredients of sparkling water are mineral water, glucose, and many more.
