The method of preparation of the oak extract

 

(57) Abstract:

The invention can be used in the wine industry. In aqueous-alcohol solution or softened water make oak shavings or chips and the extraction is carried out with stirring. Use wood chips or shavings, made of wood of oak (Quercus robur) is aged less than 80 years, between the top of the trunk and 40-50 cm from the ground up. In the extraction process on the mixture periodically affect the acoustic field with frequency 22-50 kHz and intensity fluctuations 4-40 W/cm3within 20 s to 10 min, while the extraction was carried out within 1-3 days, with the frequency of the acoustic field from 1 to 3 times. Oak shavings or chips are used in quantities of from 50 g to 0.5 kg per 1 DM3water or water-alcohol solution. The method allows to obtain oak extract can improve the quality of the finished wine products made with its use, making complex shades of plum, hazelnut, caramel, vanilla, almond and tone aging in taste and aroma.

The invention relates to the wine industry.

Known method of preparing the concentrate oak by water e the evaporation diffusion juice with subsequent drying of the mass to the crystalline state. Then powdered drug oak pour softened water and with stirring, dissolve the water-soluble part, and the precipitate was separated using a separator. Finished water oak extract used in the industry. To obtain a water-alcohol oak extract aqueous extract splitout handle brightening substances, fined, filtered. Finished water liquid oak extract is used in industry (1).

The disadvantage of this method is that when receiving a powdered drug oak upon evaporation of the diffusion juice and drying the resulting mass is lost valuable aromatherapie components of oak wood, making drinks, obtained on its basis, have a low organoleptic properties.

The method for extracting water-soluble tannins, where the shavings from the new oak staves are placed in a tank with softened water and treated with ultrasound at a frequency and intensity of vibrations, respectively 18-20 kHz and 2-3 watts/cm2within 60 minutes the resulting aqueous extract is used in industry (2).

The disadvantage of this method is the use in the extraction process, skge the absence of a required alcohol concentration, that allows you to get oak extract high quality, so wine products, prepared on its basis, has a low organoleptic properties.

The technical result of the proposed method is to obtain a product of higher quality.

This result is achieved by the method of preparation of the oak extract provides for the introduction of water or water-alcohol mixture of oak shavings or chips and their extraction. According to the proposed method for the preparation of the oak extract use shavings or chips in the amount of from 50 g to 0.5 kg per 1 DM3extractant, shavings or chips are made from the wood of oak (Quercus robur) is aged less than 80 years, between the top of the trunk and 40-50 cm from the ground up, in the process of extraction solution periodically affect the acoustic field with the frequency and intensity of vibrations, respectively 22-50 kHz and 4-40 W/cm3over time the effects of the acoustic field from 20 s to 10 min, when the frequency of the acoustic field from 1 to 3 times during the total duration of the process 1-3 days.

The proposed method shall sledom3water or solution. For the preparation of the oak extract use chips with a particle size of 1.0-1.5 cm and a thickness of 5-6 mm or chips, twisted in the form of rollers with a diameter of 10-20 mm and a length of 10-20 mm, made of wood of oak (Quercus robur) is aged less than 80 years, between the top of the trunk and 40-50 cm from the ground up. For a more complete extraction of the components of oak wood, the process is carried out in the acoustic field with the frequency and intensity of vibrations, respectively 22-50 kHz and 4-40 W/cm3over time the effects of the acoustic field from 20 s to 10 min, when the frequency of the acoustic field from 1 to 3 times during the total duration of the process 1-3 days. The resulting aqueous or aqueous-alcoholic oak extract is used in the production of wine products.

The proposed method provides for obtaining a finished product of high quality.

Example 1

Use wood chips with a particle size of 1.5 cm and a thickness of 5 mm, made of wood of oak (Quercus robur) is aged less than 80 years, between the top of the trunk and 40 cm from the ground up. Chips set in the range from 250 to 1 DM3water-alcohol solution with an alcohol content of about 40 what are the acoustic field with the frequency and intensity of vibrations respectively 30 kHz and 20 W/cm3over time the effects of the acoustic field 5 min at a frequency of impact 3 times during the total duration of the process 3 days.

Received the oak extract is filtered and used in industry for the preparation of blends of cognac.

Example 2

Use shavings, twisted in the form of rollers with a diameter of 20 mm and a length of 10 mm, made of wood of oak (Quercus robur) is aged less than 80 years, between the top of the trunk and 50 cm from the ground up. Chips set in the amount of 500 g per 1 DM3softened water.

For a more complete extraction of the components of oak wood in the process of infusing affect the acoustic field with the frequency and intensity of 50 kHz and 30 W/cm3over time the effects of the acoustic field 10 min at a frequency of impact 2 times during the total duration of the process 3 days. Then bring the concentration of alcohol until needed.

Received the oak extract is filtered and used in industry for the preparation of fortified wines.

The impact of the specified parameters of ultrasound on quality oak wood at a certain concentralization and qualitative composition of tannins, furan and aromatic aldehydes, lactones, volatile phenols, and other components, providing a complex with hints of prunes, nuts, caramel, vanilla, almond and tones of exposure in taste and aroma, which ensure the high quality of the finished wine products prepared using the extract.
