RU2373794C1 - Cherry plums, alycha, mirabelles and cornel compote preservation method - Google Patents

Abstract

FIELD: food industry.

SUBSTANCE: method provides for three-stage cherry plums, alycha, mirabelles and cornel compote warming up in water at temperature 60 and 75 and 85°C respectively 5, 10 and 25-30 minutes with following cooling in air flow during 20 minutes at speed 5-6 m/s. During the process the tin is turned upside down.

EFFECT: finished products quality improvement, reduced process time of preserves heat sterilisation and saving of thermal energy.

Description

The proposed method for the invention relates to the canning industry, it can be used for sterilization of compote from tkemali, cherry plum, mirabelle and dogwood in cans 1-82-1000.

Sources that were searched by this method showed that the prototype of the proposed method is a method of sterilizing canned food "Compote from tkemali, cherry plum, mirabelle and dogwood" in an autoclave [1] according to the mode

where: 25 - the duration of the period of heating water to 100 ° C, min;

(25-30) the length of the period of its own sterilization at 100 ° C, min;

25 - the duration of the cooling period, min;

85 - sterilization temperature, ° C;

88 - back pressure in the autoclave, kPa.

The disadvantages of this method are:

- long duration of the process;

- uneven heat treatment of the product;

- high consumption of thermal energy and water;

- the frequency of the technological cycle.

The aim of the proposed method is to save thermal energy, water, reducing the duration of the process and ensuring the continuity of the process of thermal sterilization.

This goal is achieved due to the fact that the cans after seaming are installed in a special carrier that provides mechanical tightness of the cans and are preheated in a bath with water at a temperature of 60 ° C for 5 minutes, followed by transfer to a bath with water at a temperature of 75 ° C for 10 min and 85 ° C for 25-30 min, followed by cooling in a stream of atmospheric air at its speed of 5-6 m / s for 20 min, and during the heat treatment, the cans rotate from the bottom to the lid with a frequency of 0.166 s ^-1 .

An example implementation of the method.

Cans with compote after sealing are installed in a carrier that provides mechanical tightness (preventing the caps from breaking during the heat treatment) and placed in a hot water bath at 60 ° C for 5 minutes. After 5 minutes, the carrier with the cans is transferred to a bath of water at a temperature of 75 ° C for 10 minutes, followed by transfer to a bath of water at a temperature of 85 ° C for 25-30 minutes. After this time, the banks are cooled in a stream of atmospheric air at a speed of 5-6 m / s for 20 minutes. In this case, in the process of heat treatment, the banks rotate from the bottom to the lid with a frequency of 0.166 s ^-1 .

Salient features of the proposed method are: three-stage heating of compote in water at temperatures of 60, 75 and 85 ° C for 5, 10 and 25-30 minutes, respectively, followed by cooling in atmospheric air at a speed of 5-6 m / s for 20 minutes

The total duration of the sterilization process according to the proposed method is 60-65 minutes, which is 15 minutes less compared to the prototype.

This mode provides a reduction in the duration of the process and thereby improving the quality of the finished product, saving heat energy and water, as well as the continuity of the process.
