Usage

Description

Sodium L-glutamate, also known as MSG or monosodium glutamate, is a sodium salt of the non-essential amino acid L-glutamate. It is a flavor enhancer that stimulates the taste receptors on the tongue, enhancing the perception of savory or umami flavors in food.

Uses

Used in Food Industry:
Sodium L-glutamate is used as a flavor enhancer for its ability to intensify the savory taste in various food products such as soups, stews, and processed meats.
Used as a Stabilizer and Preservative:
In certain food products, sodium L-glutamate is used as a stabilizer and preservative to maintain the quality and shelf life of the food.
Health Considerations:
While there has been controversy surrounding the safety of sodium L-glutamate, extensive scientific research has found no consistent evidence to support the claim that its consumption in normal amounts is harmful to human health. However, some individuals may experience adverse reactions such as headaches or nausea.

CAGED COMPOUND, AND MANUFACTURING METHOD AND EXPRESSION METHOD OF CAGED COMPOUND

PROBLEM TO BE SOLVED: To provide a caged compound excellent in light reactivity and dark place stability, and capable of deprotection by a visible light. SOLUTION: A caged compound is represented by the following general formula (1). In the general formula (1), R1 represents a hydrogen atom, a halogen atom, an alkyl group, an aryl group, a cyano group, an alkoxy group, a hydroxy group, or an alkylamino group, R2 represents an alkyl group or a hetero atom other than a nitrogen atom, R3 represents a hydrogen atom, a halogen atom or an alkyl group, X represents a monovalent anion, Y represents a monovalent organic group, Z represents a hydrogen atom or a monovalent organic group, and a represents 0 or 1, however a represents 0 when R2 represents the hetero atom other than the nitrogen atom.
