Description

The invention relates to the oil and fat industry and can be used in food, cosmetic, pharmaceutical fields and medicine.

A known oil extract of plant materials based on seeds, obtained by extraction with vegetable oil (RF patent No. 2051596, A23L 1/42, publication 01/10/1996). Seeds are pumpkin seeds. A method of obtaining an oil extract includes grinding the seeds, extraction with vegetable oil in a ratio of 1: 2 in a water bath for 1.5 hours and separating the oil extract from the solid phase by centrifugation. The vegetable oil in specific examples is corn oil. The disadvantages of this oil extract and the method of its production include a limited scope - the food industry. This oil extract and method for its preparation are the closest analogues of the claimed extract and method for its preparation.

The objective of the invention relating to the oil extract, as well as the invention relating to a method for producing an oil extract, is to expand the arsenal of oil extracts and methods for their preparation.

The technical result consists in the creation of an oil extract with wide application (in food, pharmaceutical fields and medicine) and a method for its production.

Like the closest analogue, the oil extract is an extract of plant material based on seeds obtained by extraction with vegetable oil.

Unlike the closest analogue, the seeds are burdock (Arctium) seeds, and camelina oil is used as the extractant.

Like the closest analogue, a method for producing an oil extract from seed-based plant materials involves grinding the seeds, extracting with vegetable oil, and separating the oil extract from the solid phase.

Unlike the closest analogue, burdock seeds (Arctium) are crushed, and extraction is done with camelina oil.

Ginger (Camelina Satila) is a medium-oil crop that produces relatively stable crops in the northern regions. For example, camelina of the Isikulets variety of the Siberian Experimental Station of VNIIMK, Omsk Region (Isikul), has a seed yield of 1.8 t / ha and an oil content of 42.1%.

The claimed vegetable oil extract based on burdock seeds, obtained by extraction with camelina oil, unlike the known oil extracts, has its own specificity, confirmed by tests of its acid content. The test results of an oil extract from burdock seeds obtained by extraction with camelina oil were compared with the acid content in unrefined oil from camelina seeds and in oil based on burdock seeds.

Summary of acid content 1) in an extract based on burdock seeds obtained by extraction with camelina oil, 2) in an oil based on burdock seeds, 3) in camelina oil are shown in table 1.

Table 1 Burdock seed oil extract obtained with camelina oil extraction Burdock seed oil Camelina oil Name of acid Content% Content% Content% Palmitic 5.7 7.2 5.42 Stearin 3.3 8.0 2,55 Oleic 18.5 49.2 16.21 Linoleic 39.9 35.6 17.54 Linolenic 19.7 - 36.07 Peanut 0.9 - 1.09 Begenova 0.7 - 1.46 Eicosene 7.6 - 14.45 Erukova 1,6 - 2.6

These data show that burdock seed oil extract obtained by camelina oil extraction is different in composition from burdock seed oil. In addition, the composition of the oil extract based on burdock seeds obtained by extraction with camelina oil is not the total result of the combination of the oil composition based on burdock seeds and camelina oil.

Below is a comparative table 2 of the calculated value and the actual value of the acid content in the extract based on burdock seeds obtained by extraction with camelina oil.

table 2 Name of acid The calculated value of the acid content in the oil extract based on burdock seeds obtained by extraction with camelina oil (%) The actual value of the acid content in the oil
an extract based on burdock seeds obtained by extraction with camelina oil (%) Palmitic 6.31 5.7 Stearin 5,275 3.3 Oleic 32,7 18.5 Linoleic 26.57 39.9 Linolenic 18,035 19.7 Peanut 0.5 0.9 Begenova 0.73 0.7 Eicosene 7,225 7.6 Erukova 1.3 1,6

The estimated percentage of acids indicated in table 2 was determined as follows (for example, palmitic acid according to the data in table 1):

7.2% + 5.42% = 12.62%.

We compose the proportion: 12.62% -200%, ×% -100%.

We decide the proportion: 12.62 × 100: 200 = 6.31%.

From table 2 it follows that with respect to the content of linoleic and linolenic acids in the oil extract based on burdock seeds obtained by extraction with camelina oil, an over-cumulative effect is observed. Thus, the test results show that linoleic acid is contained in an oil extract based on burdock seeds obtained by extraction with camelina oil, 13.33% more than the calculated value. And linolenic acid is also found there at 1.66% more than the calculated value.

Thus, the results of the tests, the indicators of acids contained in burdock extract in camelina oil confirm the specificity of the claimed burdock oil extract in contrast to burdock seed oil or camelina oil. The properties of the oil extract based on burdock seeds, the extractant of which is camelina oil, are not the result of combining the properties of the oil based on burdock seeds and camelina oil. This extract expands the arsenal of oil extracts.

According to the claimed method, burdock seeds are first crushed. Seeds can be either raw or dried. Next, the crushed seeds are extracted with camelina oil. To do this, the crushed seeds and camelina oil are added to each other in quantitative proportions that allow wetting the raw materials with oil, maintain the heated mixture for a time sufficient to deplete the crushed seeds. The oil extract is then separated from the solid phase. The separation of the obtained oil extract from the solid phase is carried out by any known method suitable for the separation of solid and liquid phases, for example, sedimentation, filtration, centrifugation or other.

Example 1

Fresh burdock seeds are crushed in an electric mill. The crushed raw materials and camelina oil (extractant) are added to each other in a ratio of 1: 2 (2 kg of seeds, 4 kg of camelina oil). Extraction is carried out at a temperature of 50 degrees. C for 120 hours, stirring occasionally. The oil extract is separated from the solid phase by settling, followed by filtration. The yield of oil extract was about 25%.

Example 2

Fresh burdock seeds are crushed in an electric mill. The crushed seeds and camelina oil (extractant) are added to each other in a ratio of 1: 2 (2 kg of seeds, 4 kg of oil). Extraction is carried out at a temperature of 70 degrees. C for 72 hours, stirring occasionally. The oil extract is separated from the solid phase in a settling centrifuge. The yield of oil extract was about 30%.

Example 3

Herbal raw materials are ground based on dry burdock seeds in an electric mill. The crushed seeds and camelina oil (extractant) are added to each other in a ratio of 1: 2 (2 kg of raw materials, 4 kg of oil). Extraction is carried out at a temperature of 80 degrees. C for 72 hours, stirring occasionally. The oil extract is separated from the solid phase in a settling centrifuge. The yield of oil extract was about 30%.

The resulting oil extract of plant material based on burdock seeds, obtained by extraction with camelina oil, is a yellow oil liquid with an olive shade of a characteristic pleasant nutritious, slightly sour taste.

Thus, the inventive oil extract and method for its production expand the arsenal of oil extracts. At the same time, the oil extract is widely used (in food, pharmaceutical fields and medicine), due to the properties of the raw materials to be extracted and the extractant.
