Problems solved by technology

Because this patent adopts the still traditional rectification process, and directly fractionates the supercritical fluid containing germ oil flowing out of the extraction kettle, so its CO 2 Fluid and energy consumption are large, and the separation effect is not as good as that of molecular distillation technology

Embodiment 1

[0017] Embodiment 1, the extraction of wheat germ oil and the separation of natural vitamin E

[0018] Wheat germ accounts for about 2%-3% of the whole grain mass, which contains 8%-12% high-quality vegetable fat, including a large amount of linoleic acid and other essential unsaturated fatty acids. And every 100 grams of wheat germ oil contains about 300 mg of natural vitamin E, which is the highest content in various vegetable oils. Extracting wheat germ oil by traditional technology not only has the problem of residual solvent, but also must go through refining steps such as degumming, decolorization, deacidification and deodorization to obtain commercial wheat germ oil. As for separating natural vitamin E, it is extremely difficult.

[0019] The present invention uses supercritical CO 2 Wheat germ tooth oil is extracted from wheat germ by fluid extraction technology. The system used is composed of extraction kettle - filter - pressure reducing valve - more than two sepa...

Embodiment 2

[0020] Embodiment 2, the separation of natural capsanthin and capsanthin

[0021]Capsanthin is a natural red pigment extracted from mature pepper skins. It is an ideal food coloring agent because of its bright color, non-toxicity and good thermal stability. The spicy substance in chili——capsicum, it can not only promote appetite and help digestion, but also dissolve fat and lose weight as a raw material for medicine. Due to the similar physical and chemical properties of capsanthin and capsanthin, it is extremely difficult to separate the two; after separation, the quality of the two products will be greatly improved, and the economic value will be great.

[0022] Adopt the method of the present invention to use supercritical CO 2 Fluid extraction of capsanthin containing capsicum, a certain amount of ethanol can be added as a carrier agent, and ethanol can also be used to pre-treat dried peppers. During extraction, the temperature of the extraction kettle is 30°--60°C. The ...

Embodiment 3

[0023] Example 3, the extraction of seabuckthorn oil and the refining of α-linolenic acid

[0024] Seabuckthorn is a wild plant, and its fruit is edible and also used as medicine. Seabuckthorn oil is rich in nutrients and a variety of biologically active ingredients beneficial to the human body, and has strong sterilization, pain relief, tissue regeneration promotion and cancer prevention effects. Seabuckthorn oil is rich in α-linolenic acid, and α-linolenic acid is the most basic and primitive substance in the process of life. However, it cannot be synthesized in the human body and can only be taken from food. Since my country has abundant seabuckthorn resources, but has not been well utilized in the past, it is of great significance to develop the extraction of seabuckthorn oil and the refining of α-linolenic acid.

[0025] Using supercritical CO 2 Seabuckthorn oil is extracted by fluid extraction technology. The device can be composed of an extraction kettle and three sep...

Abstract

A process for extracting the active component from natural product features that the supercritical CO2 fluid extraction and the molecular distillation are combined for fully playing their roles.

Description

technical field [0001] The invention belongs to the field of chemical separation technology, which is related to food industry, pharmaceutical industry and cosmetic industry. Specifically, it involves the use of supercritical CO 2 Fluid extraction technology and the method of extracting active ingredients in natural products with molecular distillation technology. That is, the present invention provides a supercritical CO 2 Fluid extraction technology and molecular distillation technology are cleverly combined to extract a new method of active ingredients in natural products. Background technique [0002] Supercritical fluid extraction technology is a new type of chemical separation technology developed by taking advantage of the specific increase in the solubility of fluids above the critical temperature (Tc) and critical pressure (Pc). Due to CO 2 Its Tc=31.06°C; Pc=7.39MPa; and critical density ρc=0.448 g / cm 3 , that is, its working temperature is closest to room tem...
