Description

The invention relates to the production technology of canned compotes.

A known method of producing compote from apples, involving the preparation of prescription components, the preparation of sugar syrup with water solids of 22-29%, packing apples and syrup, sealing and sterilization (Collection of technological instructions for the production of canned food. Volume II. Part 2. - M .: APPP "Canned Fruit", 1992, p. 75-162).

The disadvantage of this method is the content in the target product of a large number of boiled fruits.

Closest to the proposed one is a method of producing compote from apples, which involves preparing the recipe components, roasting and extracting coffee to produce the corresponding extract, decaffeinating it, preparing syrup based on it, packing apples and syrup, sealing and pasteurizing (Ioitko V.M., Zaitseva A.L., Zaitsev M.V. Preservation technology using coffee // Collection of reports of the VI International Scientific and Practical Conference "Improving the Technologies and Equipment of Food Production." 1. - Mn .: Nesvizhskaya Integrated Printing House they S.Budnogo, 2007 s.260-263)..

This method allows you to get compote with a specific coffee shade of taste and aroma and slightly reduce the content of boiled fruits in the target product by replacing sterilization with pasteurization, but has a sophisticated technology due to the need for decaffeination of the extract and a reduced shelf life of the target product.

The technical result of the invention is to obtain compote with a specific coffee tinge of taste and aroma in the absence of coffee in the recipe, simplifying the technology and reducing the content of boiled fruits in the target product without reducing its shelf life.

This result is achieved by the fact that in the method of producing compote from apples, which involves preparing the recipe components, preparing syrup on the extract, packing apples and syrup, sealing and heat treatment, according to the invention, the prepared dandelion root is cut, dried in the microwave field to a residual moisture content of about 20% at power of the microwave field, providing heating of the dandelion root to a temperature inside the pieces of 80-90 ° C, for at least 1 hour, fry and grind, the prepared rye grain is fried, mix the root vanilla and rye grain in a weight ratio of 7: 3, the resulting mixture is extracted with drinking water at a phase ratio of 1: (6-7) and periodically depressurizing the extraction mixture until water boils, the corresponding extract is separated and filtered, the syrup is prepared with dry 22-29% of substances, and heat treatment is carried out until industrial sterility is achieved.

The method is implemented as follows.

Prescription components are prepared according to traditional technology. The preparation of apples, depending on the type of compote being prepared, may include, in addition to inspection and washing, core cutting or cutting while removing the stem and seed chamber and / or peeling.

The prepared dandelion root 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 to provide a drying time of dandelion root for 1 hour and warming 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. 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 extractives with the minimum specific energy consumption.

Then the dandelion root and rye grain are fried using traditional technology. Dandelion root is crushed and mixed with rye grain in a weight ratio of 7: 3. The resulting mixture is poured with drinking water at a phase ratio of 1: (6-7) and extracted with periodic depressurization of the extraction mixture until water boils at the recommended process parameters (RU 2255788 C1, 2005). After extraction is complete, the extract is separated from the meal and filtered by any known technique. Sugar is added to the obtained extract with a solids content of 18-19.5% and a syrup with a solids content of 22 to 29% is cooked in accordance with standard formulations using standard technology (Collection of technological instructions for the production of canned food. Volume II. Part 2. - M .: APPP "Canned Food", 1992, p. 75-162).

Apples and the resulting syrup are Packed, sealed and sterilized with a ratio of components and sterilization modes in accordance with standard technology.

An experimental check was carried out during canning with pieces of skinless apple varieties Welsey with a solids content of 11% in glass jars with a capacity of 1 dm ³ . The canning was carried out according to standard technology (control), according to the closest analogue (standard) and by the proposed method (experience). The results of the experimental verification are summarized in table.

Thus, the proposed method allows to obtain compote with coffee shades of taste and aroma in the absence of coffee in the recipe, to simplify the technology and reduce the content of boiled fruits in the target product without reducing its shelf life.
