Difurfuryldisulfide Product Overview
Difurfuryldisulfide (CAS 4437-20-1, FEMA 3146) is a high-impact sulfur-containing heterocyclic flavor monomer that dominates roasted and savory flavor formulation. As a core furan-disulfide compound, it delivers intense and multi-layered sensory characteristics. Although it shows strong sulfuric intensity at high concentrations, it develops elegant roasted coffee, nutty, and cooked meat notes after proper dilution. Naturally present in thermally treated foods and roasted coffee, Difurfuryldisulfide serves as an essential base material for building authentic reaction flavor profiles. 2,4-Dimethyl thiazole(Internal link: You can pair this item with our to enrich overall savory depth.)
Physical & Chemical Properties of Difurfuryldisulfide
To begin with, Difurfuryldisulfide appears as a pale yellow oily liquid at room temperature. It carries a precise density of 1.233 g/mL at 25°C and features a refractive index between 1.585 and 1.589. Meanwhile, it has a boiling point of 112–115°C under 0.5 mmHg and a flash point of 113°C, which ensures safe and stable industrial application. In terms of solubility, it mixes easily with ethanol, edible oils and most organic solvents, while it only dissolves slightly in water. Furthermore, it maintains excellent thermal stability during baking, extrusion and high-temperature food processing. For storage stability, it avoids deterioration if you keep it sealed and away from strong light or acidic environments.
Key Applications of Difurfuryldisulfide
- Build roasted coffee, meat and nut flavor bases
- Enhance savory seasonings, sauces, broth and meat-type flavours
- Add complexity to roasted snacks, soup bases and onion savory formulations
- Boost deep roasted, sulfur-rich background notes for reaction flavours
Recommended Dosage
Typical finished‑food dosage: 0.01‑3 ppm. Adjust according to your formula and sensory targets. This ingredient carries strong aroma strength, so start with low dosage during formula trials.
