Description
Technical Field
The invention belongs to the technical field of ganoderma lucidum spore oil preparations, and particularly relates to oil-soluble plant extract emulsion.
Background
The Ganoderma spore oil is oily lipid extracted from wall-broken Ganoderma spore by supercritical carbon dioxide fluid extraction technology, and integrates multiple active ingredients of Ganoderma spore. The ganoderma lucidum spore oil is yellow transparent liquid, the main components are saturated fatty acid, unsaturated fatty acid and the like, and the ganoderma lucidum spore oil contains a small amount of ganoderma lucidum acid components and has the effects of resisting cerebral ischemia/reperfusion injury, resisting oxidation and eliminating free radicals.
Although the ganoderma spore oil can be used for various purposes, the use effect is not obvious. The effect is obviously limited by its own characteristics: is fat-soluble. Because of being fat-soluble (oil) substances, the ganoderma lucidum spore oil is insoluble in water and only soluble in trichloromethane, and the trichloromethane is a substance with higher toxicity. The characteristic of poor solubility ensures that although the ganoderma lucidum spore oil is difficult to absorb in the digestive system, the ganoderma lucidum spore oil needs to enter the liver for metabolism and absorption after being taken, and further plays the physiological function of the ganoderma lucidum spore oil, so that a certain part of the ganoderma lucidum spore oil is inevitably excreted in the digestive system, and even the part of the ganoderma lucidum spore oil entering the liver cannot be completely absorbed.
In order to ensure the absorption of the ganoderma lucidum spore oil by human body, the ganoderma lucidum spore oil needs to be made into water-soluble. The current technical proposal is that the water phase (containing water, emulsifier, emulsification assistant and other water-soluble substances) and the oil phase (ganoderma spore oil/other oil-soluble substances needing to be added) are respectively heated, dissolved, prepared and mixed for emulsification, and the emulsification method is emulsification by a high-speed shearing machine or direct emulsification by a high-pressure homogenizer. However, the existing ganoderma spore oil emulsion emulsifier needs to ensure more emulsifier dosage to realize better emulsification effect, and the existing ganoderma spore oil emulsion product has unstable quality and is easy to have the phenomena of oil and water stratification, cracking, phase inversion, flocculation, corruption and the like during storage.
