Methyl Propyl Trisulfide: A Key Ingredient in the Flavor and Fragrance Industry and Its Applications

Recently, Methyl Propyl Trisulfide CAS No.: 17619-36-2 FEMA:3308,has garnered significant attention in the food and flavor industries due to its unique aromatic properties and versatile applications. This sulfur-containing compound, known for its distinctive scent, has become a "secret weapon" for perfumers and food developers. This article delves into the content, national standards, primary uses, and the significant role of Methyl Propyl Trisulfide in the flavor and fragrance industry.

Content and National Standards of Methyl Propyl Trisulfide

Methyl Propyl Trisulfide is naturally found in plants such as garlic and onions, but its content is extremely low, typically less than 0.01%. Due to limited natural sources, it is primarily obtained through chemical synthesis in industrial production. According to China's "National Food Safety Standard for the Use of Food Additives" (GB 2760-2014), Methyl Propyl Trisulfide is approved as a food flavoring and can be used as needed in production. However, its residual levels in final products must comply with safety standards to ensure consumer health.

Primary Uses and Functions

Methyl Propyl Trisulfide is renowned for its strong sulfurous, onion-like, and garlic-like aroma. It is a key component in formulating meat, seafood, and seasoning flavors. At very low concentrations (typically in the ppm range), it significantly enhances the flavor profile of products, imparting a realistic meaty and savory taste. Additionally, Methyl Propyl Trisulfide is widely used in seasonings, convenience foods, and snack foods to improve flavor complexity and depth.

Role and Applications in the Flavor and Fragrance Industry

In the flavor and fragrance industry, Methyl Propyl Trisulfide plays an irreplaceable role. Below are its main application scenarios:

1. Meat Flavors: As a core component in building the foundational aroma of meat flavors, Methyl Propyl Trisulfide can simulate the characteristic scents of boiled and roasted meats, enhancing the authenticity of products.

2. Seafood Flavors: In seafood flavors, it enhances the savory and oceanic notes, making the flavors more realistic.

3. Seasoning Flavors: In products like soy sauce and sauces, Methyl Propyl Trisulfide elevates the complexity and layering of flavors, making them more appealing.
