This investigation was initiated as a result of proposals in the literature that dietary nicotine intake could contribute to the level of nicotine metabolites in biological fluids such as salivary… Expand
Odor thresholds of microbially induced off-flavor compounds in apple juice.
- B. Siegmund, B. Pöllinger-Zierler
- Chemistry, Medicine
- Journal of agricultural and food chemistry
- 29 June 2006
Microbially derived off-flavor is a major problem in apple juice production as it diminishes the sensory quality of the juice significantly. Fifteen relevant off-flavor compounds that are formed in… Expand
Determination of off-flavour compounds in apple juice caused by microorganisms using headspace solid phase microextraction–gas chromatography–mass spectrometry
- Barbara Zierler, B. Siegmund, W. Pfannhauser
- Chemistry
- 23 August 2004
Abstract In apple juice the presence of off-flavour is one of the most frequent causes for consumers rejections and, consequently, represents an important problem to apple juice producers. In this… Expand

The contribution of dietary nicotine and dietary cotinine to salivary cotinine levels as a nicotine biomarker
- B. Siegmund, D. E. Leyden, +4 authors Helmut Reif
- Chemistry
- 1 August 2001
Abstract Dietary nicotine, as a source of nicotine biomarkers such as salivary cotinine, has been a controversial topic, mainly because of limited published data on nicotine in foods. Recently, a… Expand
