The main component of monosodium glutamate is sodium glutamate, according to the content of sodium glutamate is divided into a number of specifications, 99% of which is the crystallization of needle or granular, the remaining several are mixed with different amounts of concentrated salt and monosodium glutamate powder or mixed salt crystals. The quality standard of MSG: with the color and taste of normal MSG, no odor and inclusions should be allowed. The adulteration of monosodium glutamate can be judged preliminarily from the appearance, because monosodium glutamate has a fixed crystalline form, mixed with powder or other forms of salt can be seen; for white powder monosodium glutamate can be taken equal amount of monosodium glutamate and salt with equal amount of isothermal hot water to dissolve at the same time to judge, the two completely dissolving speed is different, monosodium glutamate should be faster, and the lake. Flour can be gelatinized in hot water, and adulterated with lots of salt or starch can be judged from it. If consumers doubt when they are identified, they can be further determined by the local quality inspection agency.
1. The high-quality monosodium glutamate granules are uniform in shape, white and lustrous in color, and in granular form. The taste is still delicious when diluted to 1:100.
Second, the shape of inferior monosodium glutamate granules is not uniform, the size is not uniform, the color is black and yellow, or even granules into a lump, diluted to 1:100 ratio, can only feel bitter, salty or sweet without flavor.
3. Common monosodium glutamate adulterants include salt, starch, baking soda, gypsum, magnesium sulfate, sodium sulfate or other inorganic salts.
