Problems solved by technology

Steam distillation and simultaneous distillation extraction often destroy the heat-sensitive components in fresh plants due to high temperature, it is difficult to retain the fragrance and taste of leeks, and it takes a long time and the yield is low; ordinary solvent extraction takes a long time to heat, making the leeks Flavor ripening, the higher vacuum degree in the concentration process also makes the aroma of leeks completely lost; the extractant C0 used in the supercritical method 2 The polarity is low, not suitable for the extraction of active ingredients in fresh plants with high water content or cheaper natural plants

Embodiment 1

[0018] A preparation method of kohlrabi oil, the concrete steps are as follows:

[0019] (1) Weigh raw materials, weigh 60 parts of kohlrabi, 2 parts of bay leaves, 3 parts of star anise, 8 parts of Chuanming ginseng, 2 parts of Panax notoginseng, and 2 parts of Baikou according to parts by weight;

[0020] (2) Fill the kohlrabi in the extraction kettle, rinse repeatedly with carbon dioxide gas, exhaust the air in the kettle, and extract at an extraction pressure of 15MPa, an extraction temperature of 35°C, an extraction time of 3h, and the amount of entrainer ethanol equal to the mass of the filling material kohlrabi. Under the extraction conditions of 10% of the extraction, adjust the valves to make the carbon dioxide gas carry out full-cycle flow extraction, the pressure of the separation tank is 5Mpa, and the temperature is 30°C; after the extraction is completed, the extract is released from the bottom of the separation tank;

[0021] (3) adding its volume of 4% calcium c...

[0025] A preparation method of kohlrabi oil, the concrete steps are as follows:

[0026] (1) Weigh raw materials, weigh 65 parts of kohlrabi, 3 parts of bay leaves, 3.5 parts of star anise, 8.5 parts of Chuanming ginseng, 2.5 parts of Panax notoginseng, and 2.5 parts of Baikou according to parts by weight;

[0027] (2) Fill the kohlrabi in the extraction kettle, rinse repeatedly with carbon dioxide gas, exhaust the air in the kettle, and extract at an extraction pressure of 16MPa, an extraction temperature of 38°C, an extraction time of 3.5h, and the amount of entraining agent ethanol is the filling material kohlrabi Under the extraction condition of 11% of the mass, adjust the valves to make the carbon dioxide gas carry out full-cycle flow extraction, the pressure of the separation kettle is 6Mpa, and the temperature is 35°C; after the extraction is completed, the extract is released from the bottom of the separation kettle;

[0028] (3) adding 5% calcium chloride by volume t...

Embodiment 3

[0032] A preparation method of kohlrabi oil, the concrete steps are as follows:

[0033] (1) Weigh raw materials, weigh 70 parts of kohlrabi, 4 parts of bay leaves, 4 parts of star anise, 9 parts of Chuanming ginseng, 3 parts of Panax notoginseng, and 3 parts of Baikou according to parts by weight;

[0034] (2) Fill the kohlrabi into the extraction kettle, wash it repeatedly with carbon dioxide gas, exhaust the air in the kettle, and extract it at an extraction pressure of 18MPa, an extraction temperature of 45°C, an extraction time of 4h, and the amount of entrainer ethanol equal to the mass of the filling material kohlrabi. Under the extraction condition of 12%, adjust each valve to make the carbon dioxide gas carry out full circulation flow extraction, the pressure of the separation kettle is 8Mpa, and the temperature is 40°C; after the extraction is completed, the extract is released from the bottom of the separation kettle;

[0035] (3) adding its volume of 6% calcium chl...

Abstract

The invention discloses a preparation method for allium hookeri oil, which particularly includes the following steps: 1) weighing raw materials; 2) adding the raw material, allium hookeri, into an extraction kettle, repeatedly washing the allium hookeri with CO2 gas to exhaust the air in the kettle completely, and adjusting all valves so that full-circulating flowing extraction is carried out with the CO2 gas; 3) when the extraction is finished, discharging an extract from the bottom of the extraction kettle; 4) drying the extract with CaCl2; 5) adding liquor for liquor-washing the extract; 6) heating the liquor-washed allium hookeri oil in a pot, adding bay leaves, star anise, chuanminshen violaceum, panax notoginseng and amomum cardamomum and oil-frying the spices until fragrance is generated, and turning the fire off and cooling the spices, taking the spices out, filtering the allium hookeri oil and filling a container with the allium hookeri oil to produce a finish product. The allium hookeri oil is prepared from natural materials, has simple and practical processes, is short in production time, has a fragrant smell, and has abundant nutrients, pleasant appearance, mellow fragrance and delicious taste. Through the liquor-washing for increasing the fragrance, odors of the allium hookeri oil are eliminated, and the fragrance of the allium hookeri oil is enhanced. The allium hookeri oil, used as oil for cold dishes, is refreshing and can improve appetite.

Description

technical field [0001] The invention relates to the technical field of food chemistry, in particular to a preparation method of kohlrabi oil. Background technique [0002] Kohlrabi mostly grows in humid areas, on hillsides or under forests. For example, it can grow in areas with an altitude of 2,400 meters to 3,200 meters in the south of Cuona County, Tibet, and is cultivated by the local Menba people. It is widely cultivated in Baoshan area of ​​Yunnan Province and is called kohlrabi. Kohlrabi has the pungent aroma of green onion and garlic vegetables. The leaves resemble day lily and are close to leeks. The root flesh is plump and has a leek flavor. It is the main part of food intake and can also be used as medicine alone. All have broad application prospects. [0003] At present, the methods for extracting the aromatic and taste components in fresh spices are mainly steam distillation, simultaneous distillation extraction, solvent extraction and supercritical carbon di...
