• Semi-quantitative measurement between 0-300 mg/l (undiluted) L-Glutamate
• Convenient. No extra equipment required
• Sample treatment and assay can be performed in under 15 minutes
• Method: Visual
• Samples: Soups, sauces, milk, and more

Glutamate, is an important chemical in general metabolism. It is also widely used as a flavor enhancer in the food industry. Consumption of foods containing monosodium glutamate (MSG) have been known to cause headaches, flushing, sweating, nausea, and more. Glutamate is also a crucial mammalian neurotransmitter that is believed to be involved in a number of neurological and psychiatric disorders such as lateral sclerosis, autism, and Alzheimer’s disease.

QuantiQuik™ L-Glutamate Quick Test Strips are based on Glutamate dehydrogenase catalyzed oxidation of glutamate in which the formed NADH reduces a chromogenic reagent. The intensity of the product color is directly proportional to the glutamate concentration in the sample.
