Abstract
The invention discloses an extraction method of eucommia seed oil. The extraction method adopts the following technical scheme that static extraction is carried out, then, dynamic extraction is carried out, the outlet pressure is lower than the inlet pressure, and a periodic pressure fluctuation method and a periodic flow rate fluctuation method are independently or jointly used in the extraction process. When the extraction method provided by the invention is adopted, the oil yield of the eucommia seed oil is improved by about 4 to 10 percent, and the extraction rate reaches about 92 to 98 percent. Simultaneously, the product quality is stable, the pollution is avoided, the production is safe, and the extraction method is suitable for industrial production.
Description
Technical field
The present invention relates to a kind of extracting process, belong to food processing field.
Background technology
Eucommia ulmoides seed oil is rich in abundant alpha-linolenic acid, and main form with DHA and EPA exists in vivo.Have hypotensive, reducing blood-fat, raising memory and vision, promote infant brain to grow, antianaphylaxis, the function such as anticancer, antitumor.The content of unsaturated fatty acids is 91.18% in the eucommia ulmoides seed oil, and the total content of linolic acid, oleic acid and alpha-linolenic acid is up to 73.68%, and wherein the content of alpha-linolenic acid is up to more than 61%.
At present the preparation eucommia ulmoides seed oil is commonly used milling process.Advantage is not use inflammable and explosive solvent, no solvent residue, production and product safety, health, pollution-free; The eucommia ulmoides seed oil that only has simultaneously a milling process to produce just can detect the aucubin with hepatoprotective effect.Shortcoming is that labour intensity is large, and oil yield is lower, about 21-25%, and the east of oil obfuscation, oil is relatively poor etc.The advantage that the organic solvent lixiviation process is carried oil is that oil yield is high, can reach 30%, and shortcoming is dissolvent residual, and oil is relatively poor.
CO
2Supercritical extraction is emerging extractive technique.With the traditional method ratio, have: (1) critical temperature is 31.2 ℃, has effectively avoided at high temperature heating of extract, and you well better protect the effective constituent in the eucommia ulmoides seed oil, has protected the activity of physiologically active substance in the seed oil; (2) extraction agent is nontoxic, easily removes noresidue in the oil product; (3) extraction agent can recycle, and is without reagent consumption, pollution-free; (4) nontoxic, harmless, production safety; (5) flow process is simple, and is easy to operate, and processing parameter is easy to control, oil product and effective constituent steady quality.Therefore, CO
2Supercritical extraction will become the Main Means of eucommia ulmoides seed oil preparation.
" supercritical CO
2The research of extraction Eucommia Oil " (horse Berlin, Liang Shufang etc., Xibei Forest College's journal, 2004,19(4), 126 ~ 128) put down in writing influence factor, optimal processing parameter and the oil yield of extraction eucommia ulmoides seed oil.The oil yield of producing eucommia ulmoides seed oil with the method is 28.53%, but supercritical CO
2Extraction is subjected to the impact of several factors, comprises pressure, temperature, static extracting time, dynamic extraction time, CO
2Flow, raw material granularity etc.Any one factor all may cause the variation of extraction component.Therefore, need to be to supercritical CO
2Extraction improves, and guarantees as far as possible quality and the stability of the finished product.
