Industrial production method of lycopene microemulsion

Abstract

The invention discloses an industrial production method of a lycopene microemulsion. The method comprises the following steps: uniformly mixing a lycopene crystal, a co-emulsifier, an oil-soluble emulsifier and an antioxidant to obtain a suspension; carrying out nano grinding on the suspension to obtain an oil phase; uniformly mixing water with a water-soluble emulsifier to obtain a water phase; and finally, uniformly mixing the water phase and oil phase, thereby obtaining the lycopene microemulsion. According to the method, the co-emulsifier and oil-soluble emulsifier are added into the raw material lycopene crystal and subjected to nano grinding to obtain the nano oil suspension, and the nano oil suspension is mixed with the water and water-soluble emulsifier to obtain the lycopene microemulsion. The material treatment capacity is increased, and the industrial production efficiency is enhanced only by grinding the oil phase without using vegetable oil or organic solvent to dissolve the lycopene. The method has the advantages of simple technique and high product safety, can prepare the high-content lycopene microemulsion, is suitable for industrialized continuous production, and has obvious economic benefits.

Description

technical field [0001] The invention belongs to the technical field of natural pigment application, in particular to an industrial production method of lycopene microemulsion. Background technique [0002] Lycopene is one of the carotenoids. There are many double bonds in the lycopene molecule, which has strong physiological functions. For example: lycopene has a strong antioxidant activity, which can avoid the antioxidant damage of cells and prevent the occurrence of cancer. Secondly, lycopene can also prevent the occurrence of cardiovascular and cerebrovascular diseases, and delay aging. [0003] Lycopene is a fat-soluble pigment, easily soluble in lipids and non-polar solvents, insoluble in water, hardly soluble in strong polar solvents such as methanol, ethanol, etc., soluble in aliphatic hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons such as Organic solvents such as ethane, benzene, and chloroform. Due to the water insolubility of lycopene, the appl...

AI Technical Summary

Problems solved by technology

Due to the water insolubility of lycopene, the application of lycopene is greatly limited

At present, in order to improve the hydrophobicity of lycopene, the main methods are: 1) Microcapsule technology: However, due to its insufficient particle size, after the wall material is dissolved, lycopene cannot be well suspended in the aqueous solution, and will soon occur. settlement

2) Microemulsion technology: In the prior art, the preparation of lycopene microemulsion mainly relies on dissolving lycopene crystals in oil or solvent. The process is relatively cumbersome, and high temperature melting or The way of solvent dissolution will not only cause the loss of lycopene, but also the risk of solvent residue

For example, the patent with publication number CN 101991175 A provides a lycopene microemulsion product with high cis-isomer content and its preparation method, which dissolves lycopene in vegetable oil at high temperature (about 150°C) , and then add co-emulsifier, emulsifier and water at 100°C to make a microemulsion; this method is not only cumbersome, but also uses high temperature many times, which can easily cause the loss of lycopene

The patent application with the publication number CN200710024111.6 provides a water-soluble lycopene nano-dispersion product and its preparation method, which dissolves lycopene in an organic solvent, and then adds co-emulsifiers and emulsifiers, through high-pressure The microemulsion is prepared in a homogeneous manner, and then the solvent residue is removed by rotary evaporation; the microemulsion prepared by this method is not only complicated in process, but also has the risk of solvent residue in the obtained microemulsion
