L-MANNONO-1,4-LACTONE - Introduction

L-mannonic gamma-lactone(L-mannonic gamma-lactone) is an organic compound with the chemical formula C6H8O6. It is a white crystalline solid that is soluble in water and other polar solvents. L-mannonic gamma-lactone have acidic properties and can be hydrolyzed to 1-mannoic acid.

L-mannonic gamma-lactone is used as a sour agent and preservative in the food industry, and can be used in foods such as beverages, canned foods and jams. It can also be used as an ingredient in cosmetics and personal care products to adjust the acid-base balance and enhance moisturizing effects.

The preparation of L-mannonic gamma-lactone can generally be obtained by oxygenation of L-mannonic acid. One common method is to react 1-mannonic acid with oxygen or hydrogen peroxide by heating in the presence of a catalyst.

L-mannonic gamma-lactone are considered to be relatively safe under normal conditions of use. However, excessive intake may cause gastrointestinal discomfort or allergic reactions. For some people, such as those who are allergic to mannose acid or have specific health problems, consult a doctor before use. During use and storage, correct handling and safety measures should be followed, and contact with eyes and skin should be avoided.
