Identification
Description
A colorless liquid with tobacco-like aroma.
Regulatory Status
CoE: Used provisionally. Food: 10 ppm
FDA: n/a
FDA (other): n/a
JECFA: ADI: Acceptable. No safety concern at current levels of intake when used as a flavoring agent (2004).
Usage
Reported uses (ppm): (FEMA, 1994)
Natural occurrence
Reported found in wheaten bread, other types of breads, boiled and cooked beef, grilled and roasted beef, lamb (roasted), lamb and mutton liver, beer, several types of brandy, cocoa, black tea, roasted filbert (Corylus avellano), roasted peanut (Arachis hypogea), heated beans, Bantu beer, coriander seed (Coriandrum sativum L.) and other natural sources.
Production
It is obtained by bromination of ethylpyrazine, followed by oxidization to obtain it.
Description
2-Acetylpyridine: a widely used food additive
2-Acetylpyridine, also named 1-(2-pyridinyl)ethanone or methyl 2-pyridyl ketone, is a "popcorn"-like compound and often used as the food additive and flavouring substance in tobacco, ice cream, milk, cooked rice and other food products. Generally, 2-acetylpyridine exists in a colorless to yellowish liquid and can be naturally found in rice, hazelnuts, Yahonkaoluo leaves and cocoa. Studies have also suggested that it can be used as an intermediate to synthesize a series of chemical compounds with antiviral activity. For example, Abid et al. prepared the various oxime ether derivatives of 2-acetylpyridine and evaluated their antiamoebic activities against the HM1:IMSS strain of E. histolytica[1].
