| Accelerated Solvent Extracts (ASE) and SFE of green pepper show a different spectrum of compounds than the essential oils. Main volatiles were α-pinene (0.8-4.4%), sabinene (5.6-14.0%), β-pinene (1.8-6.9%), 3-carene (4.3-10.1%), limonene (4.6-7.8%), β-caryophyllene (6.5-26.3%), and elemol (3.3-12.9%); with higher percentages of β-phellandrene (1.2-2.3%), (E/Z)-sabinene hydrate (1.5-3.6%), terpinen-4-ol (2.1-4.5%), α-copaene (1.2-4.8%), δ-cadinene (0.7-3.0%), and δ-cadinol (0.6-3.4%). \\ | Accelerated Solvent Extracts (ASE) and SFE of green pepper show a different spectrum of compounds than the essential oils.

| AEDA analysis of white pepper with very intense off-odour showed highest FD factors for α-pinene and linalool (FD 1024), the off-odorants with high FD factors were 3-methylindole (skatol, fecal-swine-manure, FD 512), and 4-methylphenol (fecal, horse-like, FD 256). 3-Methylphenol (FD 128, phenolic), and the cheesy smelling 2-methyl and 3-methyl butanoic acids (FD 32) were also present. Regardless of the origin these off-odorants are characteristic constituents of white pepper, formed during fermentation. They can be minimised combining a frequent change of water during fermentation with a reduction of the fermentation time to four days, starting with fully ripe fruits. \\ | AEDA analysis of white pepper with very intense off-odour showed highest FD factors for α-pinene and linalool (FD 1024), the off-odorants with high FD factors were 3-methylindole (skatol, fecal-swine-manure, FD 512), and 4-methylphenol (fecal, horse-like, FD 256). 3-Methylphenol (FD 128, phenolic), and the cheesy smelling 2-methyl and 3-methyl butanoic acids (FD 32) were also present.
