Abstract

FIELD: food industry.

SUBSTANCE: the present innovation deals with manufacturing fruit-berry puree by applying additives out of a microorganism. One should perform the following technique: raw material should be rubbed through without separating waste products, decanted to mix centrifugate with precipitation and a solid residue obtained after extracting Pythium coloratum micromycete biomass in the preset sequence to be repeatedly decanted. Then one should supplement the centrifugate with an extract obtained after the first extraction of the same biomass with a nonpolar extragent in supracritical state to be heated, packed and thermally treated at obtaining the target product.

EFFECT: increased quality of the target product.

Description

The invention relates to the technology of the canning industry.

A known method for the production of fruit puree, including the preparation of raw materials, rubbing it without separating waste, decanting, mixing the centrate with sediment, re-decanting with the separation of the centrate, its heating, packaging and heat treatment (RU 2079227 C1.10.05.1997).

The disadvantage of this method is to obtain the target product is not high enough quality.

The technical result of the invention is to improve the quality of the target product.

This result is achieved in that in a method for producing fruit puree, including preparing the raw material, wiping it without separating the waste, dropping it, mixing the centrate with the precipitate, decanting it again with separating the centrate, heating it, packing and heat treating it according to the invention before decanting it into a mixture of the centrate with the precipitate is introduced solid residue obtained after sequential extraction of the biomass of micromycete Pythium coloratum non-polar extractant in a supercritical state, water, alkali, water, acid Ota, water, alkali and water in an amount of about 0.05% by weight of fruit raw material, and after repeated decantation centrate administered in an extract obtained after extraction of the same equivalent amount of biomass nonpolar extractant in a supercritical state.

The method is implemented as follows.

Fruit and berry raw materials are prepared according to standard technology, and then wiped without separation of waste. The mashed mass is decanted and the centrate is mixed with the precipitate.

The dry biomass of Pythium coloratum micromycete is extracted with a non-polar extractant, for example, carbon dioxide or hexane, in a supercritical state and the extract is separated, which is further used to obtain the target product. 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 stages listed above is introduced into the mixture of the centrate with the precipitate of fruit and berry raw materials in an amount of about 0.05% by weight and the mixture is decanted again. The dosing accuracy of the solid residue is determined mainly by the accuracy of the dosing equipment used.

The extract obtained at the stage of extraction of biomass of micromycete Pythium coloratum at the stage of extraction with a non-polar supercritical extracting agent from the same amount of biomass as the solid residue introduced into the mixture of the centrate with the precipitate is introduced into the separated centrate. Next, the centrate is heated, Packed and subjected to heat treatment for sterilization or pasteurization to obtain the target product.

The product obtained according to the described technology, in comparison with the product obtained according to the closest analogue, is distinguished by the best preservation of the color of the feedstock and does not stratify during the entire warranty period of storage, which is estimated as an increase in its quality.

Example 1

Puree is prepared according to the technology described above from Wellsie apples and preparations isolated from the biomass of Pythium coloratum micromycete using hexane, sodium hydroxide and hydrochloric acid as a non-polar extractant. Control canned food is prepared at the same technological parameters, but without the use of preparations from the biomass of micromycete Pythium coloratum. After 6 months of storage, the experimental canned foods have a uniform consistency, and the control ones have a peeled liquid phase at 6% of the can’s height. The color of the test samples of the target product is lighter than the control.

Example 2

Puree is prepared according to the conditions of example 1, but using peaches of the Stoyky variety, nitrogen as a non-polar extractant, potassium hydroxide, and acetic acid. The result qualitatively completely coincides with example 1.

Example 3

Puree is prepared according to the conditions of example 1, but using cantata blackcurrant and carbon dioxide as a non-polar extractant. After 6 months of storage, the canned prototypes have a uniform consistency, and the control samples have an exfoliated liquid phase at 18% of the can’s height. The color of the experimental samples of canned food is more saturated than the control, in which a brownish tint appeared, especially noticeable in the exfoliated solid phase.

Thus, the proposed method improves the quality of the target product by improving its organoleptic properties.
