    摘要： A powder-form composition of 2-acetyl-1-pyrroline incorporated with a support of maltodextrin and/or cyclodextrin. The composition is prepared by hydrolyzing a 2-(1-alkoxyethenyl)-1-pyrroline with an acid to obtain a reaction medium, adding an equimolar amount of a base to the reaction medium to obtain a neutralized reaction medium containing 2-acetyl-1-pyrroline, combining maltodextrin and/or cyclodextrin with the neutralized reaction medium to obtain a support solution and freeze-drying the support solution to obtain the composition.

    摘要： Anisotropic compounds having a nematic phase have the formula ##STR1## wherein A is a cyclic radical selected from the group consisting of ##STR2## Z is selected from the group consisting of a single bond, a --CH2CH2-- group, a methyleneoxy group and an oxymethylene group,n is 1 or 2,p is 0, 1, or 2,r is 0 or 1,X is selected from the group consisting of fluorine, chlorine, bromine, iodine, nitrile and methyl,R.sup.1 and R.sup.2 are selected from the group consisting of hydrogen, C.sub.1 -C.sub.12 -alkyl, C.sub.1 -C.sub.12 -alkoxy, C.sub.1 -C.sub.12 -alkanoyloxy and C.sub.1 -C.sub.12 -alkylamino and cyclic groups of the formulas ##STR3## wherein R.sup.3 through R.sup.6 are selected from the group consisting of hydrogen, C.sub.1 -C.sub.12 -alkyl, C.sub.1 -C.sub.12 -alkoxy, C.sub.1 -C.sub.12 -alkanoyloxy, and C.sub.1 -C.sub.12 -alkylamino, and Z.sup.2 through Z.sup.6 represent a Z group, with the provisos that:(A) none of the above aromatic radicals (10), (11), (13), (14) or (15) is directly bonded to the C-atom of a methyleneoxy or oxymethylene group; and(B) at least one X group is methyl when only one or none of the groups R.sup.1 and R.sup.2 is a cyclic radical of formulas (13) or (16), A has the formula (12), Z is a single bond, and any of Z.sup.3 or Z.sup.6, if present, is a single bond.Compounds having the defined lateral substituents on the rings have a reduced tendency to form smectic phases as compared with the compounds not having such lateral substituents.

    摘要： A flavorant agent is prepared by incubating a medium of baker's yeast, elemental sulfur and a reducing sugar to obtain a reaction medium from which hydrogen sulfide gas evolves and then the reaction medium is treated with heat to obtain the flavorant agent. A further flavorant agent is obtained by separating the supernatant of the reaction medium from reaction medium residue, and the reaction medium or supernatant may be mixed with a flavor precursor material and heated to obtain a flavorant composition.
