Abstract

FIELD: food industry.

SUBSTANCE: method envisages oil treatment with a hydrating agent, the mixture exposure, a phosphatide emulsion separation from the hydrated oil and the phosphatide emulsion drying. After the phosphatide emulsion separation one introduces milk whey into it in an amount of 3.0-7.0% of the phosphatide emulsion weight. Then one performs heating up to 70-80°C. Then one proceeds with dividing into a water and a fat phases, the fat phase separation and drying to produce a phosphatide concentrate.

EFFECT: invention allows to produce a high quality phosphatide concentrate with low acid and peroxide number.

Description

The invention relates to the oil industry and can be used to obtain a phosphatide concentrate.

A known method of producing a phosphatide concentrate, including processing on a hydrodynamic emitter, the formation of sediment, separation of the precipitate, drying of phosphatides (Application RU No. 2002119762).

The disadvantage of this method is the low content of phospholipids in the phosphatide concentrate, as well as high acid and peroxide values of the oil isolated from the phospholipid product.

A known method of producing a phosphatide concentrate, comprising mixing unrefined oil with a hydrating agent in an amount necessary to completely remove phospholipids, exposing the mixture, separating the phosphatide emulsion from the hydrated oil, drying the hydrated oil and phosphatide emulsion to obtain a phosphatide concentrate (N. Harutyunyan, Processing technology fats - 3rd ed. [Text] - M .: Pishchepromizdat, 1998. - S.42-54.).

The disadvantages of the method include high acid and peroxide numbers of the oil isolated from the phospholipid product, and the long drying time of the emulsion.

The objective of the invention is the creation of a highly efficient method for producing a phosphatide concentrate.

The technical result is to obtain a high-quality phosphatide concentrate with lower acid and peroxide values.

The problem is solved in that in the method for producing a phosphatide concentrate, including treating the oil with a hydrating agent, exposing the mixture, separating the phosphatidic emulsion from the hydrated oil, drying the phosphatidic emulsion, after separation of the phosphatidic emulsion, whey is added in an amount of 3.0-7.0% to the mass of the phosphatide emulsion, heated to a temperature of 70-80 ° C, followed by separation of the phases into water and fat, separation of the fat phase and drying to obtain a phosphatide concentrate.

As we have experimentally shown, whey contains proteins that, when heated, are denatured with an increase in their adsorption capacity. These proteins adsorb polar phospholipids and phase reversal occurs, with the release of fat.

The claimed method is illustrated by examples.

Example 1. In a heated unrefined sunflower oil containing 0.6% phospholipids with an acid number of 2.8 mg KOH / g, a hydrating agent is introduced - water, 2% are mixed and exposure is carried out for 30 minutes, the phosphatide emulsion is separated from the hydrated oils. In the selected phosphatide emulsion add whey in the amount of 3.0% by weight of the phosphatide emulsion. The mixture is heated to a temperature of 80 ° C to separate into two phases: aqueous and fat. The fat phase is separated by centrifugation and dried under vacuum to obtain a phosphatide concentrate.

Example 2. In a heated unrefined sunflower oil containing 0.6% phospholipids with an acid value of 2.8 mg KOH / g, a hydrating agent is introduced - water, 2% are mixed and exposure is carried out for 30 minutes, the phosphatide emulsion is separated from the hydrated oils. To the isolated phosphatide emulsion, 7.0% whey is added to the mass of the phosphatide emulsion. The mixture is heated to a temperature of 70 ° C to separate into two phases: aqueous and fat. The fat phase is separated by centrifugation and dried under vacuum to obtain a phosphatide concentrate.

Example 3. In a heated unrefined sunflower oil containing 0.6% phospholipids with an acid number of 2.8 mg KOH / g, a hydrating agent is introduced - water, 2% are mixed and exposed for 30 minutes, the phosphatide emulsion is separated from the hydrated oils. In the selected phosphatide emulsion add whey in the amount of 5.0% by weight of the phosphatide emulsion. The mixture is heated to a temperature of 75 ° C to separate into two phases: aqueous and fat. The fat phase is separated by centrifugation and dried under vacuum to obtain a phosphatide concentrate.

In parallel, the purification of vegetable oil was carried out in a known manner.

Indicators of the phosphatide concentrate obtained by the claimed and known methods are shown in the table.
