Abstract

FIELD: food industry.

SUBSTANCE: invention can be used in production of bread kvass. Performing extraction of rose flowers with liquid carbon dioxide to separate corresponding miscella. Cut yacon is dried in microwave field till residual humidity about 20 % at microwave filed power providing warming inside yacon bits till temperature of 80-90 °C for at least of 1 hour. Then, it is roasted and impregnated with separated miscella with simultaneous pressure boost. Pressure is reduced to atmospheric pressure value with simultaneous freezing of yacon, its crushing and mashing together with kvass bread and hot water. Performed settling three times with separation of liquid phase from pulp to produce kvass wort, then adding to it of 25 % of recipe quantity of sugar in form of white syrup, fermentation with bakery yeast, blending with remaining sugar in form of white syrup and bottling.

EFFECT: method allows to reduce duration of process and increase foam stability of end product.

Description

The invention relates to a technology for the production of bread kvass.

A known method of producing bread kvass, involving the preparation of prescription components, mashing kvass bread with hot water and three times infusion with separation of the liquid phase from the thick with obtaining kvass wort, adding 25% of the recipe amount of sugar in the form of white syrup, fermentation with baking yeast, blending with the remaining sugar in the form of white syrup and color and bottling (Technological instructions for the production of soft drinks. - M .: Pishchepromizdat, 1951, p. 27-41).

The disadvantage of this method is the long duration of the process.

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 by the fact that in the method of producing bread kvass, which involves preparing the recipe components, mashing the kvass breads with hot water and insisting three times to separate the liquid phase from the grounds to produce kvass wort, adding 25% of the recipe amount of sugar in the form of white syrup, fermentation with baker's yeast, blending with the remaining sugar in the form of white syrup and pouring, according to the invention, prepared rose flowers are extracted with liquid carbon dioxide with separation the corresponding miscella, the prepared yacon is cut, dried in the microwave field to a residual moisture content of about 20% with a microwave field power that ensures the heating of the yacon to the temperature inside the pieces 80-90 ° C, for at least 1 hour, fried, impregnated with the separated miscella with a simultaneous increase pressure, depressurize to atmospheric pressure while freezing the yacon, crush and grind in an amount of about 3.6% of the sugar consumption rate together with leavened bread.

The method is implemented as follows.

Prescription components are prepared according to traditional technology.

The prepared rose flowers are extracted with liquid carbon dioxide and the miscell is separated according to the 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 p. 7-15).

The prepared yacon is 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 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 premature caramelization of sugars. Drying in the microwave field at a temperature of less than 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 extractives with the minimum specific energy consumption.

Then the yakon is fried according to traditional technology (Nakhmedov F.G. Technology of coffee products. - M .: Light and food industry, 1984, p. 58-73).

The fried yakon is loaded into a sealed container and poured to impregnate the separated miscella. The amount of miscella is selected according to well-known recommendations (A. Khristyuk. Improving the technology of beer production. - Krasnodar: KNIIHP, 2003, pp. 133-134). The pressure in the tank automatically rises to a value corresponding to the pressure of saturated vapor of carbon dioxide at the temperature of the impregnation. Impregnation time is calculated according to the known laws of mass transfer (Kosmodemyansky Yu.V. Processes and apparatuses for food production. Textbook for students of technical schools. - M .: Kolos, 1997, pp. 135-162). In this case, carbon dioxide is absorbed and the icon is saturated with the extractive substances contained in the miscella.

After the impregnation is completed, the pressure in the vessel is released to atmospheric pressure, which ensures the evaporation of part of the carbon dioxide and the freezing of the yacon, which is crushed by any known method.

Prepared kvass breads and crushed yakon in an amount of approximately 3.6% by weight of the recipe amount of sugar are rubbed with hot water and infused for three times to separate the liquid phase from the thick, as in the closest analogue, to obtain kvass wort, to which 25 % of the prescription amount of sugar in the form of a white syrup and fermented with baking yeast.

Due to the presence of inulin extract in the extract, the fermentation proceeds faster than in the closest analogue, and the color of the fermented wort is more stable due to the presence of coloring substances in the extract of the extract, which does not require subsequent colorization.

The fermented wort is blended with the remaining sugar in the form of a white syrup and sent for bottling to obtain the desired product.

When conducting an organoleptic evaluation of the target product in accordance with GOST R 53094-2008, it was found that, compared with the product obtained by the closest analogue, the foam resistance of the experimental product is increased by 20-28%, and the bread flavor of the experimental product is more pronounced and has light shade of plant material used in miscella production.

Thus, the proposed method allows to reduce the duration of the process and increase the resistance of the foam of the target product.
