Description

The invention relates to a technology for the production of flour confectionery.

There is a method of producing raw gingerbread, which includes the preparation of recipe components, the preparation of syrup from sugar and molasses, its mixing with wheat flour, mélange, soda, ammonium carbonate and flavoring, kneading, molding, baking and glazing (Confectionery technology. Ed. Rapoport A .L. - M.-L.: Pishchepromizdat, 1940, p. 352-401).

The technical result of the invention is to increase the volume of the target product while maintaining uniform porosity.

This result is achieved by the fact that in the method for producing raw gingerbread, which involves preparing the recipe components, preparing syrup from sugar and molasses, mixing it with flour, mash, soda and ammonium carbonate, kneading, molding, baking and glazing, according to the invention, a mixture of wheat flour is used and flour from yacon, taken in a weight ratio of about 8: 1, flour from yacon is prepared by extracting nutmeg with liquid nitrogen to separate the corresponding miscella, preparing the yacon, cutting it, and drying microwave field to a residual moisture content of about 20% with a microwave field power that provides heating of the yacon to a temperature inside the pieces of 80-90 ° C for at least 1 hour, frying, impregnating the separated miscella with a simultaneous increase in pressure to a value corresponding to the pressure of saturated nitrogen vapor at the temperature of impregnation, depressurization to atmospheric pressure with simultaneous freezing of the yacon and its cryo-grinding in the medium of released nitrogen, and the dough is prepared with the following components by weight with an accuracy of ± 5%:

The method is implemented as follows.

Prescription components are prepared according to traditional technology.

The prepared nutmeg is extracted with liquid nitrogen and the miscella is separated according to the known technology (Kasyanov G.I., Kvasenkov O.I., Nematullaev I., Nesterov V.V. Processing of plant material 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 power of the microwave field 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, deterioration in the taste and aroma of gingerbread. Drying in the microwave field at temperatures below 80 ° C and a reduction in drying time of less than 1 hour lead to a decrease in the number of pores and the formation of unbaked zones in the target product. 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 best organoleptic properties of the target product with minimal specific energy consumption.

Then the yakon is fried according to traditional technology, loaded into a cryomill drum and poured to impregnate the separated miscella. The ratio of miscella and impregnated raw materials is calculated by the concentration of the extract in miscella to achieve an extract content in miscella equal to 0.5% by weight of the impregnated raw material. 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). At the same time, nitrogen is absorbed and the raw materials are saturated with miscella aromatic substances.

After the impregnation is completed, the pressure in the drum is vented to atmospheric pressure, which ensures the evaporation of nitrogen and freezing of the yacon, and then it is cryo-grinded in the medium of released nitrogen to obtain a flavored flour.

Prepared wheat flour and flavored flour from the yacon are mixed in a weight ratio of about 8: 1.

Sugar, molasses and drinking water are loaded into a kettle with a stirrer and knead until sugar is completely dissolved, after which a mixture of flour, melange, soda and carbon ammonium salt is gradually added to the resulting syrup, mixed to a homogeneous consistency to obtain a dough that is molded, baked and glazed with getting raw gingerbread.

The obtained target product was compared with commercially available raw glazed cakes, produced by traditional technology.

The experimental fracture product did not visually differ from the control sample, but had a density of 22-24% less, which is the basis for the assertion of an increase in the volume of products due to an increase in the number of pores.
