Embodiment

[0029] The supercritical carbon dioxide extraction method of scallion seed oil is as follows:

[0030] (1) Raw material: mature wild scallion seeds, material clarity ≥ 99%;

[0031] (2) Drying: Dry the scallion seeds naturally or place them in an electric heating constant temperature blast drying oven at 40°C, and the water content is less than 6%;

[0032] (3) Pulverization: pulverize the dried scallion seeds and sieve them for subsequent use, the particle size is 20-40 mesh;

[0033] (4) supercritical carbon dioxide extraction: the above-mentioned pulverized Shallot seeds are placed in the extraction kettle of a supercritical carbon dioxide extraction device (HA121-50-01 type supercritical extraction device, produced by Hua'an Supercritical Extraction Co., Ltd., Nantong, Jiangsu), Set the optimal process parameters: extraction pressure 31.50MPa, extraction temperature 46.00°C, extraction time 101.60min, CO 2 The flow rate is 40Kg / h, the separation I pressure is 8-10MPa, th...

Abstract

The invention relates to a method for extracting allium mongolicum regel seed oil by using supercritical carbon dioxide, belonging to the field of food processing and specially used for comprehensive development and deep processing of allium mongolicum regel seeds. The allium mongolicum regel (Allium Mongolicum Regel) seeds are dried (the water content is smaller than 6 percent) and crushed into 20-40 meshes, the allium mongolicum regel seed oil is extracted by adopting an supercritical carbon dioxide extraction technology, and the optimal process parameters are set as follows: the extraction pressure is 31.50MPa, the extraction temperature is 46.00 DEG C and the extraction time is 101.60min. Under the conditions, yellow decant oily substances are obtained with the purity of above 99 percent and the maximum extraction yield of 15.067 percent. The process for extracting the allium mongolicum regel seed oil by using the supercritical carbon dioxide provides a new method for deep processing of the allium mongolicum regel seeds and has the advantages of strong operability, higher yield, high extraction efficiency, high product purity, little damage of active components, favorable safety, favorable repeatability and the like.

Description

1. Technical field [0001] The invention relates to a method for extracting scallion seed oil with supercritical carbon dioxide, which belongs to the field of food processing and is specially used for extracting scallion seed oil. 2. Background technology [0002] Sand onion is a plant of the genus Allium in the Liliaceae family (LiLiaceae). Its scientific name is Allium Mongolicum Regel, also known as Mongolian onion and mountain onion. It is a perennial bulb herb. Distributed in southern Mongolia, Russia and Kazakhstan, and Inner Mongolia, Gansu, Xinjiang and other places in northwest my country. "Compendium of Materia Medica" records the medicinal effects of scallions: the taste is the same as scallions, pungent, slightly warm, and non-toxic. Indications: fox urine stinging poison, sand lice, shooters and other poisons in mountain streams, removing miasma and vicious poison; soaking in boiling juice, or smashing to bind, great effect. And small garlic, Rongyu, not alone,...
