Diagnostic Index

Over the last 10 years, complaints were increasingly reported from consumers that experienced dysgeusia following the consumption of pine nuts. In the present study, pine nuts samples (N= 16) from consumers that reported dysgeusia have been analyzed to identify the botanical origin of critical pine nuts samples. The fatty acid composition of the samples was performed, and diagnostic index values were used to identify the botanical origin of the samples.Pinus armandiinuts were identified in all the samples pure or in mixture withP. koraiensisnuts.P. armandiiis not reported as edible pine nuts by the Food and Agriculture Organization (FAO). This study confirmed that consumption ofP. armandiinuts may lead to dysgeusia. Based on the present study and previous work, we advise import companies to trade pine nuts from traditionally recognized species such asP. pinea, P. sibirica, P. koraiensis,orP. gerardiana.

Proximate Analyses

Anethum sowa L. (Dill) seeds were investigated to determine the fatty acid composition and proximate analyses. The seeds contain 9.36 % fatty oil. The saturated and unsaturated fatty acids contributed 6.22% and 93.78% respectively of the oil. The per cent composition of the extracted oil was identified by Gas Liquid Chromatography (GLC). Among the six fatty acids identified from this study oleic acid contributed the highest proportion (87.10%), where as, linolenic, palmitic, stearic, behenic and arachidic all together contributed the rest (12.90%). Proximate analyses showed that A. sowa. seeds are good source of dietary fibre. Overall Dill seeds oil can be considered as a good source of oleic acid. Key words: Anethum sowa, dill seed oil, fatty acid composition, oleic acid, linolenic acid, Gas liquid chromatography. Bangladesh J. Sci. Ind. Res. 42(4), 455-464, 2007

Fatty Acid Compositions

SUMMARYGas liquid chromatography was used to investigate the influence of several T, S and unclassified cytoplasms on the fatty acid composition of oil from A632 and CrS4HLA maize seeds. The fatty acid compositions of the A632 and CrS4HLA seeds differed markedly from each other with respect to oleic and linoleic acids but were stable within each seed line with respect to all sixteen of the cytoplasms tested.
