Problems solved by technology

The pressing method is suitable for industrial production, but the oil must first be fried or steamed at high temperature, which will easily destroy the active ingredients in the Eucommia oil, and the oil yield is low; the leaching and extraction time required by the solvent leaching method is longer Long, the extracted crude oil needs further processing, and the production process is complicated
Commonly used purification methods such as urea inclusion method, complexation chromatography, lipase concentration method, etc. involve the use of reagents, which will lead to solvent residues and longer production time; CO 2 Although supercritical extraction method, molecular distillation method, low temperature crystallization method, etc. avoid the pollution of solvent, the production cost of the equipment used is relatively high

Embodiment 1

[0027] Embodiment 1, the method for producing high-content α-linolenic acid eucommia oil by cold pressing method comprises the following steps:

[0028] ①Selection of Eucommia ulmoides fruit: select plump fruit with no mildew, no insect erosion, and normal color and smell by winnowing, and remove impurities;

[0029] ②Peel off the shell, use a sheller to destroy the cuticle, and get the seed kernel;

[0030] ③ Seed kernels are dried and dried under vacuum and reduced pressure at 60°C;

[0031] ④ Put the eucommia seed kernels into the oil filter bag, and put the oil filter bag into the press;

[0032] ⑤The pressing pressure is 800kg / cm 2 , the process of boosting the pressure is 30 minutes, and the pressure is maintained for 50 minutes to obtain cold-pressed Eucommia seed oil;

[0033] ⑥Cold-pressed eucommia seed oil is filtered to remove some oil residues;

[0034] ⑦ Purification, using ultrafiltration membrane concentration technology to purify a-linolenic acid in Eucommi...

Abstract

The invention provides a method for preparing eucommia seed oil by a low-temperature cold-pressing technology and purifying high-content a-linolenic acid. The method comprises the following steps of careful selection, husking, drying, metering charging, pressing, filtration, purification, examination and sterilization packaging processes on eucommia fruits. The method is carried out at a normal temperature, guarantees relative stability of active substances such as a-linolenic acid in eucommia seed oil in processing, does not adopt any chemical substances in pressing, effectively avoids the pollution produced by a solvent on eucommia seed oil, adopts a nanofiltration purification technology and improves a-linolenic acid content. The method for extracting eucommia seed is simple, can be realized easily, has a low production cost, low energy consumption and high a-linolenic acid content, and can provide a good raw material for development of foods, health-care foods or medicine products. Various nutrients in slag cake subjected to pressing are not destroyed and produce active effects on further development of eucommia products.

Description

technical field [0001] The invention relates to a low-temperature pressing method for eucommia seed oil, in particular to a method for preparing eucommia ulmoides seed oil by cold pressing and using ultrafiltration membrane purification technology to increase the content of a-linolenic acid in eucommia ulmoides oil. Background technique [0002] Eucommia ulmoides Oliver (Eucommia ulmoides Oliver) is a rare and valuable nourishing Chinese herbal medicine unique to my country. Modern pharmacological experimental studies have shown that Eucommia ulmoides has the functions of strengthening muscles and bones, nourishing liver and kidney, lowering blood pressure, anti-inflammatory and antibacterial, anti-cancer, and enhancing immunity. These pharmacological activities Mainly based on Eucommia bark and Eucommia leaves as the research objects, but there are few related researches on the extraction, purification, development and utilization of Eucommia seed oil. Since the total fatty ...
