Abstract

FIELD: chemistry.
SUBSTANCE: nutmeg is mixed with hop in mass ratio of 1:10. The obtained mixture is extracted with liquid nitrogen with separation of the corresponding miscella. Yacon is cut and dried in a microwave field at given process parametres. The yacon is then mixed with malt. The obtained mixture is saturated with the obtained miscella while simultaneously increasing pressure to a value which corresponds to pressure of saturated nitrogen vapour at saturation temperature. Pressure is lowered to atmospheric pressure level with simultaneous freezing of the mixture, which then undergoes cryogenic grinding in the medium of the released nitrogen. Water is added and saccharification is carried out to obtain wort. Brewing yeast is added to the wort. Fermentation and filtration are carried out to obtain the end product.
EFFECT: method shortens duration of the process and increases foam stability of the end product.

Description

The invention relates to brewing technology.
A known method of producing flavored light beer, comprising crushing Jerusalem artichoke, pouring it with drinking water, saccharification in the presence of an enzyme preparation and separating the liquid phase, mashing and saccharification of malt, adding hops to it, boiling, introducing the separated liquid phase 30 minutes before boiling, cooling , brewing yeast, fermentation and filtering (Dahuenon E. Development of beer technology using tubers of cultures growing in the Republic of Ben as unmalted raw materials . Ph.D. Thesis Abstract n -. M .: MGAPP, 1995, s.13-19).
The disadvantage of this method is the long duration of the process.
A known method of preparing mash from partially unmalted raw materials, which involves mixing grain and malt, impregnating them with gas-liquid hop hops at higher than atmospheric pressure, expanding when depressurizing to atmospheric pressure, mashing and saccharification (RU 2319737 C1, 2008).
This method cannot be implemented when using tuber crops as unmalted raw materials.
The technical result of the invention is to reduce the duration of the process and increase the resistance of the foam of the target product.
This result is achieved in that in a method for producing flavored light beer, which involves preparing wort from malt, unmalted raw materials and hops, introducing brewer's yeast into it, fermenting and filtering, according to the invention, nutmeg and hops are mixed in a weight ratio of 1:10 and extracted the resulting mixture with liquid nitrogen with the separation of the corresponding miscella, as an unmalted raw material, a yacon is used, which is cut and dried in the microwave field to a residual moisture content of about 20% at the microwave field power, ensuring heating the yacon to a temperature inside the pieces of 80-90 ° C, for at least 1 hour, mix the yacon and malt in a weight ratio of 1: (40-60), impregnate the mixture with separated miscella with a simultaneous increase in pressure, depressurize to atmospheric with simultaneous freezing of the mixture, it is subjected to cryo-grinding in the medium of the released nitrogen, poured with drinking water and saccharified to produce wort. The method is implemented as follows.
Nutmeg and hops are mixed in a ratio by weight of 1:10, the resulting mixture is extracted with liquid nitrogen and the miscella is separated by known technology (Kasyanov G.I., Kvasenkov O.I., Nematullaev I., Nesterov V.V. Processing of plant materials with liquefied and compressed gases. - M .: AgroNIITEIPP, 1993, pp. 7-15). By using the known effect coextraction (Lomachinsky V., O. Effect on Kvasenkov efekta on sekstraktsiya vrhu indicators on protsesa on ekstrahirane with CO 2. Hranitelno flavoring Buisness-2007, №3, s.49-51) achieved yield of extractives mixtures are greater than their total yield during separate extraction of the components.
Yakon is prepared according to traditional technology, cut and dried in the microwave field to a residual moisture content of about 20% for at least 1 hour. Moreover, according to well-known dependencies (Gubiev YK Scientific and practical principles of thermotechnological processes of food production in the electromagnetic field of the microwave. Abstract of the dissertation of the Doctor of Technical Sciences - M .: MTIPP, 1990, pp. 7-11) calculate the power microwave fields, allowing for the drying time of the icon 1 hour and heating to a temperature inside pieces of 80 and 90 ° C. The microwave field power is set greater than or equal to the second value and less than or equal to the smaller of the first and third values of the calculated powers.
Drying in the microwave field at temperatures above 90 ° C leads to caramelization of sugars. Drying in the microwave field at temperatures below 80 ° C and a reduction in drying time of less than 1 hour lead to a reduction in the yield of extractives. Since an increase in the drying time automatically leads to an increase in the specific energy consumption, the maximum value of the drying time is determined by the Harrington desirability function for the maximum yield of extractive substances with minimal specific energy consumption.
Yacon and malt are jointly loaded into the drum of the cryomill in a weight ratio of 1: (40-60) and poured to impregnate the separated miscella. The amount of miscella is chosen according to well-known recommendations (Khristyuk A.V. Improving the technology of beer production. - Krasnodar: KNIIHP, 2003, p.133-134). The pressure in the drum automatically rises to a value corresponding to the pressure of saturated nitrogen vapor at the impregnation temperature. Impregnation time is calculated according to the known laws of mass transfer (Kosmodemyansky Yu.V. Processes and apparatuses of food production. A textbook for students of technical schools. - M .: Kolos, 1997, p.135-162). In this case, nitrogen is absorbed and the mixture is saturated with the extractive substances contained in the miscella.
After the impregnation is completed, the pressure in the drum is vented to atmospheric pressure, which ensures evaporation of nitrogen and freezing of the mixture, and then cryo-grinding of the mixture in the medium of nitrogen released is carried out.
The crushed mixture is poured with drinking water and saccharified to produce wort. In this case, by analogy with the known technology (RU 2319737 C1, 2008), due to the use of gas-liquid miscella, the process of saccharification of the mash is accelerated and the yield of extractive substances into the wort is increased.
It should be noted that the implementation of wort hopping at the mashing stage significantly reduces the duration of the preparation of the wort.
Brewer's yeast is introduced into the obtained wort and, using the technology of the closest analogue, it is fermented and filtered to obtain the desired product.
When conducting an organoleptic evaluation of the target product in accordance with GOST R 51174-98, it was found that its color corresponds to light beer when using an yacon in the above ranges, and in comparison with the product obtained by the closest analogue, the foam resistance is increased by 15-20 %, which is probably due to an increase in the content of surfactants in the extract of the apple with the described technology for its processing before mashing.
Thus, the proposed method allows to reduce the duration of the process and increase the resistance of the foam of the target product.
