Description

The invention relates to methods for storing vegetable oils.

Camelina oil is an oil obtained from the seeds of the camelina plant (Carthamus tinctorius). Camelina oil has valuable nutritional properties and is widely used in the culinary and cosmetic industries. Camelina oil has an islandy taste and a neutral aroma, so it is actively used for frying different types of meat, as it does not lose its flavor properties when heated and gives dishes a piquant taste. Often used as an ingredient in sauces, vinaigrettes, salads and gravies, and added to soups and cereals. In cosmetology, it is used as a moisturizer and nourisher for the skin.

Unrefined cold-pressed oil is rich in the following vitamin composition:

- Vitamin E - tocopherol, is considered a vitamin of beauty and has a positive effect on the production of the hormone estrogen by a woman’s ovaries, which makes a woman attractive in the eyes of the opposite sex. Vitamin E moisturizes and smoothes the skin and promotes skin regeneration;

- Vitamin A is presented in camelina oil in two forms. Carotene and retinol, actually vitamin A itself. Carotene is a provitamin and is broken down in the liver to retinol. This vitamin is involved in protein synthesis, in the formation of cellular and subcellular membranes, and stimulates collagen synthesis. In combination with vitamin E, it works wonders in terms of the beauty of hair, skin, and nails;

- Vitamin F is the polyunsaturated fatty acids themselves;

- Vitamin K is the group name for hydrophobic and lipophilic vitamins that take part in protein synthesis, ensures the proper level of blood clotting, participates in the metabolic processes of bones and connective tissue, and is a catalyst in the absorption of calcium and vitamin D.

The mineral composition of camelina oil includes magnesium, potassium, calcium, selenium, and zinc.

Before the Soviet period in the history of Russia, camelina oil was a traditional Russian agricultural crop and was among the leaders in consumption, and now camelina oil is experiencing a “rebirth” and takes its rightful place in the diet of people leading a healthy lifestyle.

But due to the fact that raw, unrefined camelina oil is a perishable product (2-3 months), cannot be stored for a long time in plastic or glass containers and dries out, manufacturers prefer not to produce it, which in turn leads to the search for new solutions storage of oil producers.

Known edible oil spray in an aerosol can under pressure for frying and baking with sunflower oil 300 ml (https://www.ozon.ru/product/maslo-sprey-dlya-zharki-i-vypekaniya-antiprigarnyy-sprayli-s-podsolnechnym -maslom-300-ml-1158533519/?advert=hHWkhY8m6Dbqb15ZtwvZcjk3H0grGYlPiWW5nI9yRYRWZYKEQco4ZsUxcv7LVujfFiuTGcIec_0oPKETQC6IZUMeavIGBTJMUDJaA3uYC5IkKhu8Igb fE4D5JzS3_yi02SqKpgext5PeMslJF85tf-8CaefsmylaHHR50Pb_Y5n7qDqyVohKuE18bfarVEINWzpnOPgZECoAOLnUflTwAJ2r0PbHe_PxaWESxOizuG1O3IN7ijmFfPMniElGWrBP9JR3W8RH &avtc=1&avte=2&avts=1702028942).

The disadvantage of this device is that aerosols were not used to store camelina oil and in contact with propellants, the taste of camelina oil changed and the oil quickly dried out.

The technical objective of this invention is to develop a method for storing raw pressed unrefined camelina oil and extending its shelf life.

This technical problem is solved by the fact that, just like in a known analogue, edible oil is placed in an aerosol package under pressure in a evacuated bag, the aerosol valve is pressed in and air is forced between the bag and the container.

A feature of this invention is that raw, unrefined camelina oil is pumped into a double vacuum bag, consisting of two two-layer bags of food grade aluminum AMg2 with a 0.2 mm vacuum cushion between the layers.

The invention is illustrated by a detailed description and illustrations, which show:

Fig. 1 - view of an aerosol can with a evacuated bag:

a) view in size with injected oil: 1 - evacuated bag, 2 - aerosol valve, 3 - steel cylinder;

b) type of a fully filled bag with oil: 1 - evacuated bag;

c) view with a three-mode dispenser-spray installed on the cylinder: 3 - steel cylinder, 4 - three-mode dispenser-spray.

Fig. 2 - cross-sectional view of a two-layer evacuated bag consisting of two layers of food-grade aluminum: 1 - evacuated bag, 2 - aerosol valve, 5 - vacuum cushion.

The evacuated bag (1) is placed in an aerosol can (3) and the aerosol valve (2) is pressed in, after which the propellant gas is pumped into the can (3). Raw pressed unrefined camelina oil is pumped (Fig. 1 a, b) into a double evacuated bag with an aerosol valve, consisting of two two-layer bags (1) of food grade aluminum AMg2 with a vacuum cushion (5) - 0.2 mm between layers (Fig. 2 ). Then a three-mode spray dispenser (4) is installed (Fig. 1c). The oil is pumped into a vacuum-sealed bag from 50 ml to 500 ml and stored at a temperature from +4°C to +20°C.

The oil was packed in a double vacuum-sealed bag made of food-grade aluminum with a vacuum cushion, allowing the oil to be stored for 1.5 to 2 years.

The quality of camelina oil in the proposed packaging was tested by the quality department of Tyumen Aerosols LLC after 1, 5 and 2 years of storage.

The quality department established that the freshness and its original natural aroma and taste were preserved, in addition, the polyunsaturated fatty acids were:

- α-Linolenic acid - 40% of all fatty acids contained in camelina oil;

- Linoleic acid - 22%;

- Eicosadiene - 2%;

- Oleic - 18%;

- Eicosene - 14%;

- Erucovaya - 3%;

- Palmetic and stearic saturated fatty acids, which are part of camelina oil - from 1%.

The proposed storage method has shown that raw pressed unrefined camelina oil, packed in a double two-layer vacuum bag made of food-grade aluminum, is stored longer, unlike classic packaging (glass or plastic), preserves freshness and its original natural aroma and taste, and also protects the oil from exposure light, air, dust, insects, viruses and bacteria.
