Description

The invention relates to a technology for the production of coffee substitutes.

A known method of producing a coffee beverage, which includes receiving and separating inulin-containing raw materials, roasting, crushing, grinding, sieving and mixing with other milled components (Nakhmedov F.G. Technology of coffee products. - M.: Light and food industry, 1984, p. 107 -110).

The disadvantage of this method is to obtain an insoluble drink, the preparation of which is accompanied by the formation of a large amount of waste.

The technical result of the invention is to obtain a new coffee drink from unconventional raw materials using non-waste technology.

This result is achieved in that the method of producing sunflower drink involves preparing the sunflower, cutting, drying it in the microwave field to a residual moisture content of about 20% with a microwave field power that provides heating of the sunflower to a temperature inside the pieces of 80-90 ° C, for at least 1 hours, frying and cryo-grinding in liquid nitrogen.

The method is implemented as follows.

The sunflower 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, Yu.K. Scientific and practical fundamentals of the heat-technological 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) microwave field power values, allowing to provide drying time for topsoil 1 hour and heating to a temperature inside pieces of 80 and 90 ° С. 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 premature caramelization of sugars. Drying in the microwave field at a raw material temperature below 80 ° C and a reduction in drying time of less than 1 hour lead to a deterioration in the recoverability of the target product. Since the increase in the drying time automatically leads to an increase in the specific energy consumption, the maximum value of the drying time of each type of raw material is determined by the Harrington desirability function for the maximum dispersing ability of the target product with minimal specific energy consumption.

Then the sunflower is fried according to traditional technology and subjected to cryo-grinding in liquid nitrogen to obtain the target product.

The product obtained by the described technology is instant powder with dispersing ability, determined by the modified method of VNIMI (Derney J. Production of instant products. - M.: Light and food industry, 1983, pp. 11-12), about 85% . When brewed, a cloudy brown drink forms with a taste and aroma similar to natural coffee.

Thus, the proposed method allows to obtain a new coffee drink from non-traditional raw materials using non-waste technology.
