PL213431B1 - Flavoured bitter vodka with a bioactive substance - Google Patents

Description

The subject of the invention is bitter vodka with a bioactive substance in the form of prenylflavonoids.

Prenylflavonoids are substances with anti-cancer activity (they inhibit carcinogenesis), in particular in relation to prostate, breast and liver cancer. They prevent osteoporosis (inhibit bone resorption), have antiviral and antioxidant properties, and improve the overall condition of the body.

The bioactive substance in the form of prenylflavonoids contains in particular xanthohumol with the total molecular formula C21H22O5 and / or its derivatives, such as: isoxanthohumol, dimethylxanthohumol, 6-prenylnaringenin, 8-prenylnaringenin. These substances, with a characteristic bitter taste, occur naturally in hop cones, in so-called lupulin, or can be obtained synthetically. The xanthohumol content in dried hop cones ranges from 0.2 to 1% by weight, mainly depending on the variety of hops. The growing conditions have a smaller influence on this content. The content of xanthohumol derivatives is much lower. Natural xanthohumol is mainly obtained by three methods:

1.by extracting leachates with carbon dioxide at a pressure of 50-100 MPa,

2.by extracting leachates with organic solvents such as ethanol, methanol, acetone, ethyl acetate, ethyl ether or mixtures thereof,

3. through additional extraction of leachates, first with water and then with ethanol of the extract obtained by extracting granulated hops with carbon dioxide at a pressure below 50 MPa.

Extraction products containing xanthohumol, obtained after separating the solvent, have different chemical composition and properties depending on the raw material used and the extraction method and conditions. Usually it is a solid containing 10 to 30% xanthohumol. The rest are alpha and beta acids, xanthohumol derivatives and other substances contained in hop cones.

The general name of bitter flavored vodka, type Bitters, usually containing 20-75% vol. ethyl alcohol and up to 5% extract, refers to wines, spirits and bitter liqueurs. They are produced on the basis of spirit and extracts (tinctures) of fruits, stems, leaves, bark or roots of various plants, including tropical and subtropical ones. The tinctures include: wormwood, Bittner's herbs, thyme, gentian, pepper, juniper fruit, rowan, rosehip, blackthorn, orange fruit peel, grapefruit and lime, bark of angostura, chin and sandalwood, gentian and ginger roots . Usually, compositions of many different infusions on single plant raw materials or single infusions on multi-component mixtures of these raw materials are used. Flavoring additives are used to refine these vodkas, most often sugar or caramel, aromatic additives, such as valerian, mint, lemon balm, licorice, Provencal herbs, coriander, anise, cardamom, and coloring additives in the form of plant extracts or organic dyes. Some vodkas are additionally refined by themselves through long-term aging, for example in oak barrels. The detailed recipes for making most of these vodkas are the manufacturer's secret. In general, it is not known what chemicals and in what concentrations are contained in individual vodkas and how they affect the human body. However, it is known that they have a stimulating effect, increase appetite and facilitate digestion.

The bitter quality vodkas can be used to prepare drinks, flavor cocktails and as a seasoning for pure vodkas, they can also be served with water and ice as aperitifs.

Several dozen different flavored bitter vodkas are produced in Poland, and many of the commercially available are also imported. No information has been found that bioactive substances in the form of prenylflavonoids were used in the production of any of them.

It is known, from the so-called folk medicine, for the health-promoting effect of some high-percentage alcoholic beverages, such as tinctures of green walnuts (for stomach ailments) or plum brandy from Łącko and paschal (for colds).

As the incidence of cancer and many other diseases increases rapidly with the development of civilization, it is advisable to increase the consumption of food containing substances that counteract these phenomena.

The aim of the invention is to use for the production of bitter vodkas, previously unused bioactive substances in the form of prenylflavonoids, natural or synthetic, in appropriate concentrations, which give a characteristic, slightly bitter taste, and their special feature is a health-promoting effect on the human body.

Flavored bitter vodka with a bioactive substance with a concentration of 20 to 75% by volume of ethyl alcohol with flavor, color and aromatic additives, according to the invention, contains substances in the form of prenylflavonoids, in particular xanthohumol and / or its derivatives, in a total concentration of 10 to 3000 mg / l, preferably from 100 to 1000 mg / l.

Surprisingly, it turned out that the concentrations of prenylflavonoids in this range give the vodka a characteristic, slightly bitter taste and at the same time are suitable for health-promoting effects. For the refinement of these vodkas, i.e. to improve the taste and / or smell and / or color, suitably selected generally known and used additives can be incorporated therein.

P r z k ł a d 1

To 0.5 l of 96% rectified spirit, 10 ml of an alcoholic solution with a concentration of 60 g / l of xanthohumol was added. The mixture was diluted with distilled water to obtain a volume. 1.22 I. Bitter vodka was obtained with a content of approx. 40% vol. ethyl alcohol, in which the concentration of xanthohumol is approx. 490 mg / l.

P r z k ł a d 2

To 0.5 l of 96% rectified spirit was added 15 ml of an alcoholic solution with a concentration of 60 g / l of xanthohumol, and then approx. 720 ml of a sugar solution in distilled water with a concentration of 80 g / l. 1.2 l of bitter vodka with a content of approx. 40% vol. ethyl alcohol, in which the concentration of xanthohumol is about 750 mg / l and the sugar concentration is about 48 g / l.
