Problems solved by technology

However, because lycopene has strong hydrophobicity and is almost insoluble in water, many difficulties have been encountered in the actual use process.
Although people have also tried to improve the storage stability of the product and improve its water solubility by means of microencapsulation treatment, but due to insufficient crushing of the particles, the particle size is too large, resulting in the dissolution of the microcapsule wall material during use. Finally, lycopene itself cannot be stably dispersed in the system but will quickly settle to the bottom and cannot form a uniform and stable dispersion system in the matrix, so the treatment effect is not ideal; In the production of functional food (health products), although we can use soft capsules or make tablets to avoid the problem of uneven dispersion, because the particles are larger than microencapsulated products, it is difficult to take them directly Afterwards, a large part of it will not be absorbed by the human body and play a role, and its biological value will be affected accordingly

Abstract

This invention discloses a method for preparing water-soluble lycopene nanoscale dispersion product. The method comprises: dissolving lycopene or its oleoresin in an organic solvent, mixing the organic phase with an aqueous phase dissolved with an appropriate emusilfier, breaking lycopene into nanoscale by ultrahigh pressure homogenization or ultrasonic breakage, and vacuum-distilling the organic solvent to obtain uniform and stable water-soluble lycopene nanoscale dispersion (50-500 nm). The water-soluble lycopene nanoscale dispersion product can be added into water-based foods at any ratio, which solves the problem of lycopene dissolution in water-based foods. Besides, the nanoscale lycopene particles can easily infiltrate into human cells, which can increase the biological value of lycopene.

Description

technical field [0001] A water-soluble lycopene nano-dispersion product and a preparation method thereof belong to the technical field of natural pigment applications. Background technique [0002] Lycopene is a natural edible pigment and has a wide range of physiological activities. It mainly has various biological functions such as quenching singlet oxygen and scavenging peroxide free radicals, inducing intercellular communication, regulating tumor cell proliferation, and reducing the risk of cardiovascular diseases. effect. However, because lycopene has strong hydrophobicity and is almost insoluble in water, many difficulties have been encountered in the actual use process. Although people have also tried to improve the storage stability of the product and improve its water solubility by means of microencapsulation treatment, but due to insufficient crushing of the particles, the particle size is too large, resulting in the dissolution of the microcapsule wall material d...
