ABSTRACT Buckwheat (Fagopyrum esculentum Moench) groats contain the iminosugar d-fagomine as a minor component that might contribute to the alleged health benefits of this pseudo-cereal. This study presents analysis of d-fagomine in buckwheat-based foodstuffs by liquid chromatography coupled to mass spectrometry and an estimation of its presence in the human diet based on a published population-based cross-sectional nutrition survey. d-Fagomine is present in common buckwheat-based foodstuffs in amounts ranging from 1 to 25mg/kg or mg/L, it is stable during boiling, baking, frying and fermentation, and it is biosynthesised upon sprouting. The estimated total intake of d-fagomine resulting from a diet that includes such foodstuffs would be between 3 and 17mg per day (mean for both genders; range from P5 to P95). A diet rich in buckwheat products would provide a daily amount of d-fagomine that may in part explain the beneficial properties traditionally attributed to buckwheat consumption.

    ABSTRACT: Two D-fructose-6-phosphate aldolase variants namely, single variant FSA A129S and double variant FSA A129S/A165G, were used as catalysts in the aldol addition of dihydroxyacetone (DHA) to N-Cbz-3-aminopropanal. Mathematical model for reaction catalyzed by both enzymes, consisting of kinetic and mass balance equations, was developed. Kinetic parameters were estimated from the experimental data gathered by using the initial reaction rate method. The model was validated in the batch and continuously operated ultrafiltration membrane reactor (UFMR). The same type of kinetic model could be applied for both enzymes. The operational stability of the aldolases was assessed by measuring enzyme activity during the experiments. FSA A129S/A165G had better operational stability in the batch reactor (half-life time 26.7h) in comparison to FSA A129S (half-life time 5.78h). Both variants were unstable in the continuously operated UFMR in which half-life times were 1.99 and 3.64h for FSA A129S and FSA A129S/A165G, respectively.
