Introduction: Hexamethyldisiloxane (silicone ether, MM sealing agent) is a colorless and transparent liquid that is prone to deliquescence. Insoluble in water, soluble in various organic solvents. Used as silicone oil, silicone rubber, pharmaceuticals, gas chromatography stationary liquids, analytical reagents, hydrophobic agents, etc. Obtained by hydrolysis of trimethylchlorosilane. The physical properties of hexamethyldisiloxane colorless and transparent liquids. Easily deliquescent, flammable, and in contact with high heat, open flames, and strong oxidizing agents, there is a risk of combustion. Boiling point 99.5 ℃. Flash point -1.1 ℃. Relative density (d2525) 0.7606. The refractive index is 1.3750. Insoluble in water, soluble in various organic solvents. Hexamethyldisiloxane is an important primary organic silicon raw material, often used as a capping agent in the production of silicone oil, or as a cleaning agent for silicone rubber, pharmaceuticals, gas c...

Monosodium glutamate is a commonly used condiment in family life. The scientific and rational selection of high-quality monosodium glutamate can not only allow people to enjoy delicious food, but also achieve the purpose of improving health. The use of fake and inferior monosodium glutamate not only affects people's normal diet, but also may endanger human health and safety. High-quality monosodium glutamate has the same particle shape, white and glossy color, and the particles are in a scattered state. After being diluted with water to a ratio of 1:100, the taste still tastes fresh; while the inferior monosodium glutamate particles are not uniform in shape, size, and color. The black is yellow, and even the granules become lumps. After being diluted with water to a ratio of 1:100, it can only taste bitter, salty or sweet but not umami.
The quality of monosodium glutamate is not only related to the whiteness and brightness of the particles, but also to the content of sodium glutamate. The monosodium glutamate sold on the market is marked with the content of sodium glutamate on the packaging. Generally, it can be divided into 4 specifications: 99%, 95%, 90%, and 80%. Except for 99%, the other three are added with 5%, 10%, 20% table salt. High content of sodium glutamate, white color, its quality is good.
From the perspective of improving human health, the product name, ingredient list and sodium glutamate content can be used to determine whether the product is pure monosodium glutamate (unsalted monosodium glutamate), salted monosodium glutamate or extra fresh (strong) monosodium glutamate. Try to use pure MSG containing 99% sodium glutamate.
To sum up, monosodium glutamate is a kind of nutritious, delicious, safe and reliable freshness-enhancing condiment. When cooking dishes, you should fully understand the taste mechanism of monosodium glutamate, and master the influence of various factors on the freshness of monosodium glutamate and the freshness of the ingredients. taste properties. The scientific use of monosodium glutamate can not only give full play to the freshness of monosodium glutamate to cook delicious and unique flavored dishes, but also give full play to the nutritional and health care effect of sodium glutamate to ensure the health and safety of consumers.
