    Abstract: An expression vector that includes a polynucleotide having a heterologous regulatory element operably linked to a polynucleotide sequence derived from Solanum tuberosum and encoding a xylosyltransferase capable of glycosylating gentisic acid to produce gentisic acid 5-O-β-D xylopyranoside, a transcription template having such a polynucleotide and adapted for in vitro transcription in a cell-free system, a method for producing gentisic acid 5-O-β-D xylopyranoside by culturing a recombinant host cell containing such an expression vector under conditions in which the cell expresses the xylosyltransferase from the polynucleotide, and a method for producing gentisic acid 5-O-β-D xylopyranoside by contacting a composition including gentisic acid and UDP-xylose with a recombinant xylosyltransferase. The recombinant host cell containing such an expression vector can be a bacterial cell, a plant cell, or a fungal cell, an animal cell, or a multicellular organism such as a plant.

    Abstract: A seasoning composition having enhanced salt intensity includes a salt component and a sodium-free saltiness-perception enhancing compound. The saltiness-perception enhancing compound includes at least one of gentisic acid 5-O-β-D xylopyranoside or kukoamine A. The seasoning composition exhibits a mean saltiness intensity that is about the same as a second seasoning compound that has an amount of the salt component that is greater than the salt component in the seasoning composition and that does not contain the saltiness-perception enhancing compound. A seasoned food product may include a food product and the sodium-free saltiness-perception enhancing compound. The sodium-free saltiness-perception enhancing compound may be used in a method of reducing sodium intake and a method of enhancing the salt taste of a food product. The sodium-free saltiness-perception enhancing compound may be derived from Solanum tuberosum.
