Abstract: The invention relates to a monolayer or multilayer long-life packaging containing an anethole-based alcoholic or non-alcoholic drink, characterized in that the layer in contact with the said drink is formed of a methyl acrylate/acrylonitrile/butadiene terpolymer.The invention also relates to a process intended to limit the degradation of an anethole-based alcoholic or non-alcoholic drink, in particular one which is low in alcohol or alcohol-free, characterized in that the said drinks are stored in a monolayer or multilayer long-life packaging whose layer in contact with the said drinks consists of a methyl acrylate/acrylonitrile/butadiene terpolymer.

Abstract: The invention relates to a packaging made up of at least one inner, containing an alcoholic or nonalcoholic beverage based on anethole, in which the inner foil of said packaging is made up of a film of polyamide including aromatic units.The packaging is preferably intended to contain weakly alcoholic beverages and the polyamide results from the polycondensation of meta-xylylenediamine with adipic acid.

Abstract: A process for obtaining a ground roasted plant material is disclosed. The process includes the steps of subjecting the plant material to steam at a pressure greater than or equal to about 5 bar to roast the plant material, and releasing the pressure to expel the plant material through a grid to grind the roasted plant material.

Abstract: The present invention relates to a process for washing a container, especially a food or drink container, of the bottle type, and intended to be re-employed, especially for a use with foodstuffs, in which:the reusable container is made of a homopolymer or a copolymer or a mixture of polymers, which is transparent and which has an average degree of crystallinity higher than 30%, the thickness of the walls of the container being greater than:0.35 mm with regard to the body1.00 mm at the base1.00 mm at the bottom, andsaid container is washed with an aqueous solution at a temperature higher than 70.degree. C.

Abstract: The present invention relates to a dietary composition intended to be absorbed before, during or after an activity, which comprises carbohydrates and lipids, said lipids constituting 10 to 55% of the calorie content of the composition.

Abstract: The production of natural delta-decanolide and/or delta-dodecanolide or mixtures thereof, by means of the biohydrogenation of a substrate containing the corresponding unsaturated lactones, delta-decen-2-olide and delta-dodecen-2-olide, respectively, and mixtures thereof, is performed by means of the use of a microorganism chosen from the group consisting of Saccharomyces delbrueckii, Pichia ohmeri, Hansenula anomala, Pichia stipitis, Debaromyces hansenii, Zymomonas mobilis, Zygosaccharomyces rouxii, Schawnniomyces occidentalis, Sarcina lutea and Geotrichum candidum.

Abstract: The present invention relates to a process for producing vanillin. Culturing of a basidiomycete fungus of the genus Pycnoporus or of their variants and mutants is performed in a culture medium to which a benzenoid precursor of vanillin has been added, and the vanillin produced by bioconversion of the benzenoid precursor is recovered.

Abstract: Process for the production of gamma- or delta-lactones according to the general formula: ##STR1## in which R is a saturated, mono-, di- or triunsaturated linear alkyl chain comprising from 2 to 10 carbon atoms and in which R.sub.1 is alkylene comprising 2 or 3 carbon atoms, entailing the operation which consists in culturing, in a substrate comprising a hydroxide or hydroperoxide of linoleic acid or of linolenic acid, of their esters or of their glycerides, or of an oleic acid derivative obtained by the photooxygenation of oleic acid or autoxidation of fats which contain it, a microorganism capable of performing beta-oxidations of said substrate.

Abstract: The present invention relates to a process for the preparation of a colorless aqueous solution of the organoleptic constituents of a potable spirit which has been aged in wood, wherein:(a) the potable spirit which has been aged in wood is decolorized by putting it into contact with an activated charcoal, either by addition of the activated charcoal to the bulk of the potable spirit to be decolorized, or by percolation of the potable spirit through activated charcoal placed in a column,(b) after decolorization, the activated charcoal is separated from the colorless potable spirit,(c) water is distilled over the activated charcoal recovered in (b), and(d) the distillate from stage (c), which is a colorless aqueous solution of organoleptic constituents from the starting potable spirit, is recovered.The aqueous solution can be used for the preparation of colorless whiskey.
