Abstract

FIELD: food industry.

SUBSTANCE: invention is intended for usage in preservation industry. The cherry compote production method envisages preliminary heating of fruits in jars with hot water, the water replacement with syrup and jars sealing. One performs three-stage heating in 75, 95 and 100°C water for 8, 8 and 35 minutes, subsequent three-stage cooling in 75, 95°C water during 8 and 6 minutes and subsequent cooling in 20-25°C atmospheric air flow at a rate of 5-6 m/s during 12 minutes Heating and cooling are performed at temperatures equal to 75 and 95°C in the same baths.

EFFECT: invention ensures saving heat energy and water, the process duration reduction and the ready product quality enhancement.

Description

The invention relates to the canning industry, and in particular to methods for the production of stewed cherries in cans SKO 1-82-3000.

Sources that were searched by this method showed that the prototype of the proposed method is a method of sterilizing canned "Compote of cherry" in an autoclave [1] according to the mode

where 30 is the duration of the period of heating the water to 100 ° C, min;

35 - the length of the period of its own sterilization at 100 ° C, min;

30 - the duration of the cooling period, min;

100 ° C - sterilization temperature, ° C;

118 - back pressure in the autoclave, kPa.

The main disadvantages of this method are:

- long duration of the process of heat treatment of the product;

- uneven heat treatment of the product in banks;

- high consumption of thermal energy and water.

The technical result of the invention is aimed at creating a method for the production of compote, contributing to: reducing the duration of the process; preservation of biologically active components of the raw materials used; reducing the number of boiled fruits and fruits with cracked peels; simplification of the process of implementing the method and apparatus design for its implementation, saving heat energy and water, as well as reducing costs and increasing the competitiveness of finished products.

The specified technical result is achieved due to the fact that according to the proposed method, the fruits packaged in cans are filled with hot water at a temperature of 60 ° C for 2-3 minutes, then this water is replaced with syrup with a temperature of 85 ° C, the cans are rolled up, installed in a carrier that provides mechanical tightness of the cans, and subjected to preheating in the first bath with water at a temperature of 75 ° C for 8 min, followed by transfer to the second and third baths with water at a temperature of 95 ° C for 8 min and 100 ° C for 35 min, respectively, followed by cool REPRESENTATIONS first and second baths with water temperatures of 95 and 75 ° C for 8 and 8 minutes, and continued cooling in ambient air stream temperature of 20-25 ° C and a speed of 5-6 m / s for 12 min.

An example implementation of the method.

Cans with pre-packaged fruits are poured with hot water at a temperature of 60 ° C for 2-3 minutes, then this water is replaced with syrup with a temperature of 85 ° C, then the cans are rolled up, installed in a carrier that provides mechanical tightness of the cans, and placed in a hot water bath with a temperature 75 ° C for 8 min. After 8 minutes, the carrier with the jars is transferred to a bath of water with a temperature of 95 ° C for 8 minutes, then to a bath of water with a temperature of 100 ° C for 35 minutes. After this time, the cans are cooled in the same baths: in the second bath at a water temperature of 95 ° C for 8 min and in the first bath for 8 min at a water temperature of 75 ° C, in which the next batch of cans is simultaneously heated, with further continued cooling in a stream of atmospheric air with a temperature of 20-25 ° C and a speed of 5-6 m / s for 12 minutes

The use of stepwise cooling of compote in the same bathtubs where heating is also carried out, helps to simplify the heat treatment process and the design of the sterilization apparatus, provides significant savings in heat energy and water, since with this design heat treatment is used to heat canned food in the first and second baths the heat given off by banks cooled in the same baths that have already undergone heat treatment.

The salient features of the proposed method are: pre-heating the fruits in jars before pouring the syrup with hot water at a temperature of 60 ° C for 2-3 minutes, which allows pouring syrup into the jar at a temperature of 85 ° C (according to the current technological instructions, the temperature of the syrup when pouring 60 ° C ); three-stage heating of compote in water at temperatures of 75, 95 and 100 ° C for 8, 8 and 35 minutes, respectively, followed by two-stage cooling for 8 and 8 minutes in water and 12 minutes in a stream of atmospheric air, and the processes of heating and cooling at temperatures of 75 , 95 ° C are carried out simultaneously in the same bathtubs.

This mode provides significant savings in thermal energy, water, reducing the process time and thereby improving the quality of the finished product.
