Problems solved by technology

[0005] The traditional production of β-carotene emulsion is to add the oil phase to the water phase, and then carry out shear emulsification for a certain period of time (10-60 minutes) and then homogenize. The traditional process is intermittently produced, with low efficiency and high energy consumption. It is not conducive to large-scale continuous industrial production; due to the poor stability of β-carotene and the reason that emulsions have higher stability requirements than powders, the β-carotene emulsion produced by traditional methods has poor particle size uniformity and wide particle size distribution. It is very difficult to reach the nanometer level, and the product stability is poor; at the same time, a certain amount of organic solvents are also used in the production of emulsions by traditional processes, causing certain safety risks
[0006] Patent 98105436.6 discloses a kind of beta-carotene oil-in-water microemulsion. No organic solvent is used in the production process of this emulsion. The emulsifier used is non-toxic and can be used in food, medicine and cosmetics. However, the limitations of the production process make it difficult for the particle size of the emulsion to reach the nanometer level
[0007] Patent No. 201210035294.2 discloses the production process of carotenoid emulsion. In this method, the oil phase

Abstract

The invention discloses a preparation process of a beta-carotene nano-emulsion. An aqueous phase material and an oil phase material are well dissolved and then discharged at the same time, the flows of an aqueous phase and an oil phase are respectively controlled instantaneously, and a pipeline shearing machine is used to mix, shear, emulsify and homogenize online to obtain the nano-emulsion. Due to the preparation process, each area of the materials is evenly mixed, the average grain size of the emulsion is less than 100 nm and is even, the distribution of the grain size is narrower, the stability is stronger, and the problems of poor stability and high probability of layering of the common emulsion are overcome in use. The production process uses no organic solvent, so that the safety is higher; moreover, the provided production process can continuously produce, so that the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of food additives and functional foods, in particular to a preparation process and application of a β-carotene nano-emulsion that needs to be used in the industries of food, medicine, health care products and cosmetics. Background technique [0002] In recent years, carotenoids are the most widely used food colorants approved by the state, and have been in short supply, especially natural β-carotene; at the same time, with the deepening of scientific research and the improvement of people's living standards, carotenoids Many physiological functions of carotene have been gradually recognized and discovered, such as scavenging free radicals, anti-oxidation, anti-cancer, improving immunity, delaying aging, etc. Therefore, its application field has gradually expanded from food coloring to nutritional food, Health products, pharmaceuticals, animal husbandry, cosmetics and other fields. [0003] Natural β-caroten...
