Embodiment 1

[0027] Supercritical CO 2 Extract "791 Snow Chive" chive seed oil:

[0028] (1) Raw materials: Chive seeds "791 Snow Leek" Nanjing Xingguang Seed Industry Co., Ltd., clarity ≥ 99%;

[0029] (2) Drying: Dry the leek seeds naturally or dry them in a constant temperature oven ≤ 50°C for 10-20 hours, and the water content is about 6.5%.

[0030] (3) Pulverize: pulverize the chive seeds with a high-speed pulverizer, and sieve (20 orders) for subsequent use;

[0031] (4) Supercritical CO 2 Extraction: put the above crushed leek seeds into supercritical CO 2 In the extraction device (HA121-50-01 type supercritical extraction device, produced by Jiangsu Nantong Huaan Supercritical Extraction Co., Ltd.), the extraction temperature was adjusted to 40.40°C, the extraction pressure was 22.25Mpa, the extraction time was 86.70min, and CO 2 The flow rate is 20L / h, the separation pressure of the separation tank is 4-8MPa, and the separation temperature is 30°C. After the extraction is com...

Abstract

The invention relates to a method for extracting leek rapeseed oil through supercritical carbon dioxide, which belongs to the field of food processing and is specially used for deep processing of leek rapeseeds. The raw materials and the technology comprise the following: the leek rapeseeds are dried and crushed and subjected to supercritical CO2 extraction; the extraction temperature is 40.40 DEG C, the extraction time is 86.70 minutes, and the extraction pressure is 22.25 MPa; the leek rapeseed oil is extracted; and the purity of the leek rapeseed oil is more than 99 percent, and the yield of the leek rapeseed oil is between 17.23 and 17.52 percent. The invention provides a novel method for deeply processing the leek rapeseeds. The method has the advantages of strong maneuverability, good safety, higher yield and good repeatability.

Description

1. Technical field [0001] The present invention relates to supercritical CO 2 The method for extracting chive seed oil belongs to the field of food processing and is specially used for extracting chive seed oil. 2. Background technology [0002] Leek (Allium tuberosum Rottl.) is a perennial herbaceous plant of the genus Allium in the family Liliaceae, native to China. Also known as chives and sungrass, it is an ancient vegetable with a long history of cultivation. Chive seeds are the dry mature seeds of the Liliaceae plant Chives. Leek seeds are warm in nature, pungent and sweet in taste. It has the function of warming and nourishing liver and kidney, helping yang and strengthening essence. For impotence and nocturnal emission, waist and knee pain, enuresis, frequent urination, and turbid leucorrhea (see reference: "Chinese Pharmacopoeia" 2005 edition). The fatty acid components of leek seed oil are: palmitic acid, linoleic acid, oleic acid, stearic acid, arachidic acid...
