  • Patent number: 5948453
    Abstract: 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.

  • Patent number: 5922374
    Abstract: Process for the preparation of a vegetable juice or puree in which at least one fresh vegetable is homogenized in the presence of water, where appropriate under an inert atmosphere, so as to release the flavor precursors and part of the endogenous enzymes, the homogenate is incubated at a temperature of between 0.degree. C. and 70.degree. C. for 5 min to 24 h, it is processed, where appropriate, into juice or puree, and then it is pasteurized. Cooked juice or puree derived from unblanched vegetables, capable of being obtained by the process, having an enhanced raw flavor, and a natural color which is better preserved than that of the same cooked juice or puree derived from blanched vegetables. Use of a juice or puree, or of a dry extract of juice or puree in the preparation of a food product.

  • Patent number: 5747302
    Abstract: Flavorant compounds and compositions for food substances are prepared in a food-acceptable manner by bio-conversion of a cysteine S-complex with a food-acceptable micro-organism, particularly a yeast or filamentous fungus, which, upon incubation with the complex, splits the complex at a terminal carboxyl group in a beta position to yield a product including a thiol and at least one metabolite compound, and the product is isolated.

  • Patent number: 5512290
    Abstract: 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.

  • Patent number: 5401858
    Abstract: 3- or 4-mono-, 1,3- or 1,4- or even 3,4-disubstituted derivatives of quinic acid are produced by reaction of a hydroxycinnamic acid derivative, of which the phenol group(s) is/are protected with a quinic acid derivative, to form an ester and the different reactivities of the OH functions in the 3 and 4 positions are used to carry out the esterification selectively under low temperature conditions, after which the protective groups are cleaved under controlled acidity and temperature conditions. These conditions avoid any degradation or isomerization. The process enables new quinides to be obtained in high yields.

  • Patent number: 5401521
    Abstract: 2-acetyl-1-pyrroline is prepared by hydrolyzing a 2-(1-alkoxyethenyl)-1-pyrroline compound with an acid and then the reaction medium is neutralized with an equimolar amount of a base to obtain a neutralized reaction medium containing the 2-acetyl-1-pyrroline. A cyclodextrin and/or maltodextrin support material is added to the neutralized medium which then is freeze-dried to isolate the 2-acetyl-1-pyrroline with the support to obtain the 2-acetyl-1-pyrroline incorporated with the support material.
