Dimethyl Trisulfide: The Essential Sulfur Compound for Flavors and Fragrances CAS 3658-80-8 FEMA 3275-1

Dimethyl Trisulfide (CAS: 3658-80-8, FEMA: 3275) is a prominent organic sulfur compound widely recognized for its powerful, diffusive odor profile that captures the essence of fresh cooked onions and alliaceous vegetables . As the simplest organic trisulfide with the molecular formula C₂H₆S₃ and molecular weight 126.26 g/mol, this compound plays an indispensable role in the flavor and fragrance industry .

Product Characteristics

Dimethyl Trisulfide presents as a clear yellow to pale yellow liquid with a characteristic penetrating aroma reminiscent of fresh onion, sulfurous cooked onion, savory meat, and alliaceous nuances . At typical dilution levels of 0.10% in propylene glycol, it delivers an intensely sulfurous profile with cooked onion, savory meaty, and fresh vegetative undertones . The compound exhibits a refractive index of n20/D 1.595-1.605 and density of approximately 1.195-1.210 g/mL at 20°C .

Natural Occurrence

This remarkable compound occurs naturally in various food sources, contributing significantly to the characteristic aromas of cooked vegetables from the Brassica genus. It has been identified in fresh onion juice, garlic, shallots, leek, cabbage, broccoli, cauliflower, brussels sprouts, and radishes . Beyond vegetables, dimethyl trisulfide appears in the volatile profiles of cooked chicken, pork, beef, cheeses, milk, coffee, roasted peanuts, mushrooms, asparagus, black tea, and even shellfish and squid . Its presence in aged beer and stale Japanese sake contributes to the unpalatable aroma notes that develop during storage .

Applications in Flavors and Fragrances

Dimethyl Trisulfide (FEMA 3275) serves as a vital ingredient in savory flavor compositions . Its primary applications include:

Savory Flavors: Essential for recreating authentic meaty, roasted, and grilled notes in bouillons, soups, gravies, and snack seasonings

Vegetable Profiles: Provides authentic onion, garlic, and leek characters to processed vegetable products

Savory Enhancers: Used at minute concentrations to add depth and complexity to savory systems

Fragrance Applications: Employed in specialized fragrance compositions requiring alliaceous or gourmand notes

The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated dimethyl trisulfide (JECFA number 582) and established that it presents no safety concern at current levels of intake when used as a flavoring agent . It is also approved as a flavoring substance by the European Union (FL No. 12.013)
