Problems solved by technology

However, due to the high content of unsaturated fatty acids, extraction by traditional techniques can easily cause oxidative deterioration, so it is necessary to use advanced techniques for low-temperature extraction
At present, the research on supercritical fluid extraction of myrica rubra kernel oil has not been reported yet

Embodiment 1

[0013] Using CO 2 The concrete method step of supercritical extraction bayberry kernel oil is as follows:

[0014] 1. Dry the bayberry kernels at 60°C, and control the moisture content at 7%;

[0015] 2. Put the bayberry kernels into the extraction kettle, which is a high-pressure airtight container;

[0016] 3. CO 2 It is input into the compression chamber in gaseous state to boost the pressure. The extraction conditions are pressure 35MPa, extraction temperature 45°C, static extraction for 60 minutes and dynamic extraction for 50 minutes. During dynamic extraction, CO 2 Flow 4L / min;

[0017] 4. In the extraction kettle, the oil in the kernel is dissolved in the supercritical fluid, and together with the supercritical fluid, it passes through the pressure reducing valve and then enters the separator, and then the waxberry kernel oil is separated and collected, and the extraction rate of the waxberry kernel oil up to 41.7%.

Embodiment 2

[0019] Using CO 2 The concrete method step of supercritical extraction bayberry kernel oil is as follows:

[0020] 1. Dry the bayberry kernels at 55°C, and control the moisture content at 8%;

[0021] 2. Put the bayberry kernels into the extraction kettle, which is a high-pressure airtight container;

[0022] 3. CO 2 It is input into the compression chamber in gaseous state to boost the pressure. The extraction conditions are pressure 30MPa, extraction temperature 45°C, dynamic extraction for 50min, CO 2 Flow 3L / min;

[0023] 4. In the extraction kettle, the oil in the kernel is dissolved in the supercritical fluid, and together with the supercritical fluid, it passes through the pressure reducing valve and then enters the separator, and then the waxberry kernel oil is separated and collected, and the extraction rate of the waxberry kernel oil up to 35.8%.

Abstract

The invention discloses a productive method of waxberry kernel oil by using CO2 supercritical extraction method. The method has four procedures: compression of fluid by using supercritical CO2, extraction, decompression and separation. The present invention is characterized by that: The whole extraction process is conducted at a low temperature without process of distilling or heating, neither d oxidizable problem or rancidity, and moreover, the method doesn't need refining technology as removing phospholipid, gelatine, protein or stink which are widely used in oil production industry. The advantage maximally preserves the natural character of oil. The method is an integration of extraction and separation without the problem of phase transition of material, and there is no need of high temperature heating or solvent recycling. The invention provides easy operation, shorter technical process, low cost, non-pollution, non-poison and extraction rate of more than 40%.

Description

Technical field: [0001] The present invention is a kind of utilization CO 2 The method for supercritical extraction of bayberry kernel oil belongs to the extraction of effective components by adopting modern separation technology, and specifically belongs to the field of processing and comprehensive utilization of agricultural by-products. Background technique: [0002] Red bayberry is a kind of characteristic fruit in our country. It is bright in color, delicious in taste and rich in nutrition. The processed products mainly include bayberry juice, bayberry wine, etc., which will produce a large number of bayberry cores. An enterprise with an annual output of 5,000 tons of bayberry juice will produce about 20 tons of bayberry kernels each year. Research reports have shown that myrica rubra has obvious killing and inhibiting effects on gastric cancer (803, 823) cells. Chen Jianchu and others identified the main fatty acid components of bayberry kernel oil, and detected 9 k...
