Overview
Soy Sauce Ketone, chemically known as 4-Hydroxy-2,5-dimethyl-3(2H)-furanone (HDMF), is a naturally occurring flavor compound prominent in soy sauce and other fermented foods. It is valued for its sweet, caramel-like aroma and is widely used in the food industry to enhance flavors. First identified in the mid-20th century, HDMF is now synthesized for commercial use, ensuring consistent quality and availability. Its role in creating umami and savory notes makes it indispensable in products like soy sauce, miso, and processed meats.
Physical and Chemical Properties
Soy Sauce Ketone is a white to off-white crystalline powder with a molecular weight of 128.13 g/mol. It has a melting point of 73-77°C and is soluble in water and common organic solvents like ethanol. Its stability under heat makes it suitable for cooking and baking applications. The compound’s sweet, caramel-like aroma is highly concentrated, requiring minimal quantities to achieve desired flavor profiles in food products.
Main Applications
HDMF is primarily used in the food industry to replicate or enhance the flavor of soy sauce, fermented products, and confectionery. It is a key ingredient in flavorings for snacks, sauces, and processed meats. Beyond food, it finds niche applications in perfumery and aroma therapy due to its pleasant scent. Its ability to blend well with other flavor compounds makes it versatile in creating complex flavor systems.
Safety and Storage
Soy Sauce Ketone is generally recognized as safe (GRAS) by regulatory bodies, but proper handling is advised. Avoid inhalation of dust and direct skin contact to prevent irritation. Storage should be in a cool, dry place, protected from light and moisture to maintain stability. Properly sealed containers are recommended to prevent degradation and contamination.
B2B Procurement Guide
When procuring Soy Sauce Ketone, prioritize suppliers that provide food-grade certification and detailed purity analysis. Prices vary based on purity and quantity, typically ranging from $50-$200 per kg. Evaluate suppliers for reliability, batch consistency, and compliance with international safety standards. Sample testing is recommended to ensure the compound meets specific application requirements.
