摘要:Described are mixtures of at least four of the alkadienamides defined according to the structure: n nwherein R represents C 1 -C 2 n-alkyl; R 1 is 2-methyl-1-propyl and R 2 is hydrogen, or R 1 and R 2 taken together is a moiety having the formulan n nwherein n is 4 or 5, or compositions containing substantial concentrations of such mixtures, prepared according to novel processes: (a) extraction of a ground substantially dried fruit of one of the Piper species, Piper longum Linn or Piper peepuloides ; (b) natural product-forming synthesis; or (c) synthetic product-forming synthesis. Also described are uses of the thus-formed products for augmenting, enhancing or imparting an aroma, taste, chemesthetic effect and/or antibacterial effect in or to a consumable material and/or in the oral cavity and/or on the mammalian epidermis.

标题 :Spherical radiofrequency-encoded beads
发明人：CHRISTENSEN SOEREN FLYGENRING; JENSEN OLE STAUS
权利人:VERSAMATRIX AS; CHRISTENSEN SOEREN FLYGENRING; JENSEN OLE STAUS
摘要:The invention relates to a method for the production of a composition comprising a plurality of spherical radiofrequency-identifiable (RF-tagged) polymeric beads as well the composition as such. The invention also relates to an apparatus for analyzing, identifying or sorting as well as treating a plurality of spherical radiofrequency-identifiable beads, and further to a method for recording individual reaction steps involved in the step-wise synthesis of a chemical compound on a radiofrequency-detectable bead. The beads of the composition are substantial spherical and preferably comprises a hydrophilic polymer material so as to prevent fouling.
