Description

The invention relates to the technology of the canning industry.

There is a known method for the production of canned fruits "Rubbed with sugar", which involves preparing the fruits, cavitating them in water in a rotary cavitation extractor, separating the puree, adding sugar solution to it and sterilizing it (A.Gadzhieva, Development of the technology of canned fruit from feijoa using hydrodynamic cavitation dispersant. Abstract of a dissertation of a candidate of technical sciences - M.: VZIPP, pp. 11-17, 22).

The disadvantages of this method are low productivity and low quality of the target product.

The technical result of the invention is to increase the productivity and quality of the target product.

This result is achieved by the fact that in the canned fruit production method “Rubbed fruits with sugar”, which involves preparing the fruits, cavitating them in a liquid medium in a rotary cavitation extractor, separating the puree, adding the sugar solution and sterilizing, according to the invention, adding the sugar solution is carried out until cavitation grinding, and together with a sugar solution, about 0.1% by weight of the fruit is injected into the preparation obtained by sequential extraction of the biomass of micromycete Mortierella spinosa yarnym extractant in a supercritical state, water, alkali, water, acid, water, alkali and water and then combining the first extract with the solid residue.

The method is implemented as follows.

Fruits are prepared according to generally accepted technology. Sugar is sieved, passed through a magnetic trap, and then dissolved in water and filtered. The dry biomass of micromycete Mortierella spinosa is extracted with a non-polar extractant, for example carbon dioxide or hexane, in a supercritical state. At this stage, the first extract is separated, which is used later in the preparation. Next, the biomass is sequentially extracted with water, alkali, water, acid, water, alkali and water. The solid residue obtained after completion of all the extraction steps listed above is combined with the first extract.

Prepared fruits, sugar solution and biomass preparation of micromycete Mortierella spinosa are loaded into a rotary cavitation extractor. The ratio of fruits and sugar solution is set according to the traditional recipe for canned food of this type, and the preparation from the biomass of micromycete Mortierella spinosa is taken in an amount of about 0.1% by weight of the fruit. The accuracy of the drug spraying from the biomass of the micromycete Mortierella spinosa is determined mainly by the accuracy of the metering equipment used. The resulting mixture is treated in a rotary-cavitation extractor, and then inedible parts of the fruit are isolated from it. The resulting puree is packaged and sterilized according to standard technology.

It was experimentally established that the target product obtained by the described technology better preserves the color of the feedstock than the product obtained by the closest analogue and is more resistant to delamination during storage, which is estimated as an increase in its quality. At the same time, it was found that during the warranty period of storage, the canned food obtained by the proposed method does not delaminate when the cavitation processing time is reduced in comparison with the closest analogue, which allows to increase the productivity of the method.

Example 1

Prepare canned "Apples mashed with sugar" according to the standard recipe using a rotary cavitation extractor. With the same parameters of cavitation treatment during the warranty period of storage in canned food obtained by the closest analogue, separation was observed with liquid separation at an altitude of about 10% of the tare height, experimental canned food did not exfoliate. A similar result was obtained when cavitation treatment time was reduced to 10%.

Example 2

According to the conditions of example 1, canned food is prepared using feijoa. The result qualitatively coincides with example 1 while reducing the cavitation treatment time to 7.8%.

Example 3

According to the conditions of example 1, canned food is prepared using pears. The result qualitatively coincides with example 1 while reducing the cavitation treatment time to 4.9%.

Thus, the proposed method improves the performance and quality of the canned food.
