The knowledge of putting monosodium glutamate is sauerkraut. Never put monosodium glutamate, such as sweet and sour fish and sweet and sour ribs. Because monosodium glutamate is alkaline, for example, adding alkaline monosodium glutamate to sauerkraut is chemically neutralized, that is, salt and water are generated, and a good dish will have no taste. So can it be added to alkaline food? Practice has proved that monosodium glutamate in alkaline food will also lose its flavor. Therefore, monosodium glutamate should be placed in foods that are not obviously acidic or alkaline. Pay attention to the salinity of the dish when putting monosodium glutamate. If it is too salty, the sodium ions in the salt cover up the sodium, so you can't taste it; If it is too weak, the taste of monosodium glutamate will not "hang". Finally, pay attention to the temperature. The solubility of monosodium glutamate is 85 degrees Celsius. Below this temperature, the structure of monosodium glutamate has not been decomposed. Above this temperature, it is not appropriate to put monosodium glutamate, otherwise there will be no umami flavor. Distinguish the advantages and disadvantages of honey. Honey is lighter in color. Honey is good honey because it has small white crystals and high glucose content. Honey is extremely thin, easy to flow, and its aroma is not strong, so it may be mixed with water.

In addition, some honey sold in the market is mixed with water or other impurities, which can be identified by the following methods. The difference between honey mixed with water and sucrose: drop honey on white paper or toilet paper. If the honey on the paper gradually oozes out, it means that it is mixed with sucrose and water. The difference between honey and starch: put a small amount of honey into a cup, add a proper amount of water, boil, let it cool, and drop a few drops of iodine. If the color of the solution turns blue, it means that the starch is mixed. Distinguish honey mixed with impurities: insert red-hot iron wire into honey. If there is a sticky substance on the wire, it means that it is mixed with impurities; If the line is still smooth, there is no impurity. The wonderful use of beer 1. Dilute flour with beer.

At present, there are mainly two kinds of toothpaste on the market: ordinary toothpaste (tooth cleaning toothpaste) and medicinal toothpaste. Drug toothpaste has developed rapidly in recent years, and there are many varieties. According to their functions, there are mainly the following types: 1. Anti-aging medicine toothpaste. Its unique ingredients can reduce the erosion of oral lactic acid on enamel, make enamel have acid resistance, kidney hardness, wear resistance and other properties, and have a preventive and therapeutic effect on "tooth decay". 2. Anti-inflammatory and hemostatic toothpaste. Mainly prevent and treat oral diseases such as periodontitis and gingival bleeding. The symptoms of periodontitis and gingivitis are generally gingival bleeding, deepening of periodontal sulcus, inflammation and atrophy of periodontal tissue, which leads to loosening of root and weakness of chewing.

Stir-fry in an overheated oil pan: In an overheated oil pan, it is easy to produce a stearin compound. If people often eat vegetables fried in an overheated oil pan, they are prone to low-acid gastritis and gastric ulcer. If not treated in time, they may also induce gastric cancer. 3. Cool the eggs with raw water: soak the boiled eggs in cold water. Although eggshells are easy to peel, there are still germs.

There are green food signs and labels on the package. On the left side of the label, the words "green food" are printed in standard font, and the standard batch number of green food is also printed below. If there is no such green food sign and label on the package, it is fake green food. Real green food, signs and labels have a certain proportion to the height of the packaged object. This ratio is set at 1: 6.8, and the words "Green food is allowed to be used by China Green Food Development Center" are printed. If there are signs and labels, but the proportion with the height of the packaged object does not meet the requirements, it is still fake green food. The packaging of real green food is designed according to the requirements of the national labeling law. The registered trademark, name and location of enterprise products are printed on its outer packaging. If the outer packaging is not designed according to the requirements of national standards and regulations, there is no registered trademark of enterprise products, no enterprise name, place, etc. It's fake green food. Real green food uses the imitation mark of green food. Under the fluorescent lamp, this anti-counterfeiting mark can clearly display the standard document number of the product and the autograph of Liu Lianfu, director of China Green Food Development Center. If there is no anti-counterfeiting label for green food, or the anti-counterfeiting label under fluorescence does not match, it is fake green food. The product packaging marked with "Green Food" uses the unified anti-counterfeiting label of China Green Food Development Center, and the number on the label should be consistent with the number on the product packaging. Otherwise it can be regarded as fake "green food". For the happiness and health of you and your family, please buy the green food certified by China Green Food Development Center!
