Problems solved by technology

[0007] The present invention studies the prior art, and finds that there is still no method that can completely remove phthalates. For this reason, the inventor is directed at this situation to remove phthalates in seabuckthorn seed oil. The method has been researched, and finally found a method, the method is combined with absolute ethanol extraction and activated carbon adsorption to obtain a seabuckthorn seed oil that does not contain phthalates, and further prepare it into Oral nutrition emulsion, prepare a kind of energy supplement, nutritional supplement, promote physical recovery, improve disease resistance, enhance immune function, reduce complications, and have no reproductive toxicity drugs and health care preparations

experiment example 1

[0061] The preparation method of seabuckthorn seed oil of the present invention

[0062] method 1,

[0063] Take 600g of seabuckthorn seeds, crush them, pass through a 20-mesh sieve, put them into an extraction tank, extract them at a pressure of 20MPa, an extraction temperature of 55°C, and an extraction time of 2h to obtain crude seabuckthorn seed oil. Heat the crude seabuckthorn seed oil to 60°C, stir, add 0.8% of oil weight 60% phosphoric acid, stir at 100rpm for 20min, adjust the speed of rotation to 20rpm, add 0.8% of oil weight (v / w) KOH solution with a concentration of 0.1%, and react After 20 minutes, add purified water, cool to room temperature naturally, and after standing for 5 hours, preheat the seabuckthorn seed oil to 70°C, centrifuge at 7000rpm for 10 minutes to remove phospholipids in the crude oil, take the supernatant oil and add it to the evaporator for molecular distillation. The heat conduction cycle temperature is 150°C, the column temperature is 140°C,...

Embodiment 2

[0094] Heat and stir 10g seabuckthorn seed oil without phthalates, 10g medium-chain fatty acid glycerides, 1.2g phospholipids and 0.005g vitamin E in a water bath at 60°C to dissolve the phospholipids, which is the oil phase; Stir and disperse 2.5g glycerin, 0.005g edetate calcium sodium, and 70mL water for injection in a water bath at 60°C as the water phase; add the oil phase to the preheated water phase at the same temperature under high-speed dispersion conditions, 10000rpm Disperse for 10 minutes to obtain colostrum, adjust the pH of the colostrum to 9.0 with 1mol / L sodium hydroxide solution, add water for injection to 100mL; transfer the colostrum to a high-pressure homogenizer, homogenize 3 times at 600bar, and homogenize 8 times at 1000bar; Pass the above emulsion through a 0.45 μm microporous filter membrane; fill it into a 100 mL infusion bottle, fill it with nitrogen, and sterilize it in a rotating water bath at 121 °C for 15 minutes; store the obtained sample at 4 °...

Embodiment 3

[0096] Heat and stir 10g seabuckthorn seed oil without phthalates, 10g soybean oil, 1.2g phospholipid and 0.005g vitamin E in a water bath at 60°C to dissolve the phospholipid, which is the oil phase; add 2.5g glycerol , 0.005g calcium sodium edetate, and 70mL water for injection were stirred and dispersed in a water bath at 60°C as the water phase; the oil phase was added to the preheated water phase at the same temperature under high-speed dispersion conditions, and dispersed at 10,000 rpm for 10 minutes. To obtain colostrum, adjust the pH of the colostrum to 9.0 with 1mol / L sodium hydroxide solution, add water for injection to 100mL; transfer the colostrum to a high-pressure homogenizer, homogenize 3 times at 600bar, and 8 times at 1000bar; Pass through a 0.45 μm microporous membrane; fill in a 100-mL infusion bottle, fill with nitrogen, and sterilize in a rotating water bath at 121°C for 15 minutes; store the obtained sample in the dark at 4°C.

Abstract

The invention discloses a method for preparing sea buckthorn seed oil. The method comprises the following steps: (1) extracting sea buckthorn seed oil, namely extracting sea buckthorn seed oil by adopting a supercritical CO2 extraction method to obtain crude extract; (2) degumming by acidification-hydration combination, namely removing phospholipid from the sea buckthorn seed oil crude extract obtained in the step (1) with acid and alkali solutions so as to obtain clear oil; (3) deacidifying; (4) extracting; (5) adsorbing; (6) deodorizing; and (7) cooling.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to an oral nutritional emulsion containing no phthalates and seabuckthorn seed oil and a preparation method thereof. Background technique [0002] Seabuckthorn seed oil is a kind of vegetable oil extracted from seabuckthorn seeds. Because it is rich in various fatty acids, it becomes a medicinal vegetable oil with high nutritional value. Seabuckthorn seed oil is a brownish-yellow to brownish-red transparent oily liquid, which is a highly concentrated concentrate of active ingredients of seabuckthorn. Contains more than 140 biologically active ingredients such as flavonoids, organic acids, alkaloids, sterols, triterpenes and various vitamins. The main preparation methods include: supercritical carbon dioxide extraction technology, subcritical low temperature extraction technology, etc. [0003] The crude product of seabuckthorn seed oil has high acid value, high perox...
