example 1

[0023] Add β-cyclodextrin into water, stir and dissolve at 50°C, weigh the Korean pine nut oil, mix it with methanol solvent at a ratio of 1:1 (w / w), and stir the Korean pine nut at 50°C The oil-methanol mixture was slowly added to the β-cyclodextrin aqueous solution and reacted for 0.5h. After the reaction is stopped, add 1 times the volume of ethanol to the entire reaction system, and after standing at 2°C for 12 hours, filter the mixed system with suction, and wash the filter cake with methanol twice, and dry the filter cake at 40-70°C after cleaning. The organic solvent is removed dryly, and the oil content of the obtained Korean pine nut oil molecular capsule is 10%.

example 2

[0025] Add α-cyclodextrin into water, stir and dissolve at 40°C, weigh the Korean pine nut oil, mix it with ethanol solvent at a ratio of 1:5 (w / w), and stir the Korean pine at 40°C The seed oil ethanol mixture was slowly added to the α-cyclodextrin aqueous solution and reacted for 6 hours. After the reaction stopped, the whole reaction was stirred at 6°C for 4 hours, and the mixed system was pumped and centrifuged, and the precipitate was washed twice with methanol, and the precipitate obtained after cleaning was placed at 40-70°C and vacuum-dried to remove the organic solvent, and the obtained Korean pine seed oil was Molecular capsules contain 12% oil.

Abstract

The invention provides a process for preparing a high-content Korean pine seed oil molecular capsule. The process is characterized by comprising the following steps: firstly, adding cyclodextrin or derivatives thereof into water, and performing stirring and dissolving at a certain temperature; weighing a certain amount of Korean pine seed oil, mixing the Korean pine seed oil with an organic solvent in a certain ratio (w / w), slowly adding the mixed liquid of the Korean pine seed oil and organic solvent into the aqueous solution of the cyclodextrin or derivatives thereof under a condition of heating and stirring, and performing reaction for a period; and adding an organic solvent which is 0-10 times volume of the whole reaction system after the reaction is stopped, performing stirring or standing for a certain period at the temperature of 0-8 DEG C, performing suction filtration or centrifugation for the mixed system, and washing the filter cake or precipitate repeatedly with a certain amount of an organic solvent, and performing drying or vacuum drying for the washed filter cake or precipitate under a condition of 40-70 DEG C to remove the organic solvent to obtain the high-contentKorean pine seed oil molecular capsule. The high-content Korean pine seed oil molecular capsule has the advantages of high grease solidification rate, strong stability and good fluidity, dispersibility or solubility.

Description

technical field [0001] The invention relates to a preparation process of high-content Korean pine seed oil molecular capsules, in particular to a high-content Korean pine seed oil with the advantages of high oil solidification rate, strong stability, good fluidity, dispersibility or solubility, etc. Molecular capsule production process. technical background [0002] With the development of science and the progress of society, the use and economic value of pine nuts are constantly increasing. Its seed oil contains a variety of physiologically active substances with great development value, such as vitamin A, vitamin E and many other essential substances necessary for the human body. Saturated fatty acids, phospholipids, sterols, polysaccharides, flavonoids, etc., can be eaten or used in functional foods, and are highly praised by physicians and nutritionists of all ages. Korean pine nuts contain 53% to 68% of oil, which contains a variety of unsaturated fatty acids necessary...
