Abstract

The invention relates to a process for quickly breaking cell walls of Chinese wolfberry seeds and extracting seed oil. The process comprises the following steps of: (1) breaking the cell walls of the Chinese wolfberry seeds: crushing the cleaned and dried Chinese wolfberry seeds and filling into an extraction kettle; introducing CO2 into the extraction kettle; raising the pressure in the extraction kettle to the pressure of between 40 and 45MPa at normal temperature and keeping for 10 to 15 minutes; closing air inlet valves at the two ends of the extraction kettle; and reducing the pressure in the extraction kettle to atmospheric pressure in 1 to 5 minutes to obtain the wall-broken Chinese wolfberry seeds; and (2) filling the wall-broken Chinese wolfberry seeds obtained in the step (1) inthe extraction kettle; introducing the CO2 at the same time; extracting under a supercritical condition for 60 to 70 minutes; and performing two-stage separation under reduced pressure to obtain the Chinese wolfberry seed oil. The process is simple and environmentally-friendly and is low in cost; the extraction time can be greatly shortened, so the oil yield reaches the maximum value in a shortest time; and the process can be widely applied to advanced development and production preparation of various functional unsaturated fatty acid medicaments and health foods thereof.

Description

technical field [0001] The invention relates to the field of wolfberry processing, in particular to a rapid wall breaking of wolfberry seed cells and a process for extracting seed oil. Background technique [0002] Lycium barbarum seeds are a by-product of wolfberry processing, accounting for 3% of the whole grain, and 30kg of wolfberry seeds can be obtained by processing 1t of fresh fruit. Lycium barbarum seed oil is refined by pressing or extracting wolfberry seeds. The oil contains a lot of unsaturated fatty acids, V E and phospholipids. In addition to its edible value, wolfberry oil also has medical and health care functions, and can be used as an adjuvant treatment for cardiovascular and cerebrovascular diseases such as hypertension, hyperlipidemia, and atherosclerosis. [0003] Supercritical CO 2 Fluid extraction (SFE-CO 2 ) technology is widely used in medicine, food, chemical industry and other fields. The process is easy to operate, and CO 2 It is non-toxic, t...
