English name: L-Glutamate sodium It is specially used to draw this kind of ordinary insulin. The scale on the syringe is more accurate, because it needs to draw insulin according to 0.1ml or a finer scale, so its scale is relatively small.

Properties: colorless to white columnar crystal or crystalline powder, practically odorless, relative density 1.635, heated to 120 ° C to lose crystal water. The taste is fresh and the savory threshold is 0.012 g/100 mL or 6.25×10-4 mol/L. Slightly sweet or salty. It is non-hygroscopic, stable to light, and has no change during storage. It does not decompose during normal food processing and cooking, but under high temperature and acidic conditions (pH 2.2-4.4), partial hydrolysis occurs and is converted into 5'- Pyrrolidone-2-carboxylic acid (pyroglutamic acid). At higher temperatures and strong acid or base conditions (especially the latter), conversion to DL-glutamate results in reduced taste. soluble in water. The pH of the 5 g/100 mL aqueous solution is 6.7-7.2. Slightly soluble in ethanol, insoluble in ether. Uses: scientific research, experiments, flavor enhancers; umami.
