Lutein ester microcapsule powder and preparation method thereof

Abstract

The invention discloses lutein ester microcapsule powder and a preparation method thereof. The preparation method comprises the following steps of: preparing an oil phase solution and a water phase solution respectively, and mixing and emulsifying the oil phase solution and the water phase solution; and non-water raw materials comprise the following components in part by weight: 1 part of lutein ester crystal, 0.05 to 0.1 part of oil phase antioxidant, 0.02 to 0.1 part of oil phase emulsifying agent, 0.05 to 1 part of plant oil, 0.5 to 25 parts of wall material, 0.1 to 0.5 part of water phaseemulsifying agent, 0.05 to 1 part of water phase antioxidant, and the balance of filler. In the preparation method for the lutein ester microcapsule powder, the oil-soluble lutein ester is fully dispersed in cold water in the form of sub nanometer particles, and the product can be self-emulsified in water, and is good in instant capacity and self-emulsification capacity, and high in stability, and has uniform and durable color; and the phenomena of oil floating, precipitation, adhesion to a bottle wall and the like are avoided during application. Organic solvents are not introduced in the powder, so solvent residues are avoided in the product. The production process is environment-friendly, simple and practicable, expensive equipment is not needed, and the microcapsule powder can be industrially produced easily and conveniently.

Description

technical field [0001] The invention relates to a preparation method of cold water dispersible lutein ester microcapsule powder. Background technique [0002] Lutein esters are carotenoid fatty acid esters that exist in the form of fatty acids combined with lutein. It is widely found in plants such as pumpkins, cabbage, spinach, and marigold flowers. Among them, the content is the most abundant in marigold flowers. Research has shown that intake of lutein esters increases lutein levels in blood and in the macula of the retina, thereby preventing age-related retinoid degeneration (Snodderly D.M.Am.J.Clin.Nutr.62(suppl.): 144805- 618, 1995) and cataracts (Lisa C.T, et al. Am. J. Clin Nutr. 90:509-15, 1999). And it can effectively inhibit tumor growth and prevent the occurrence of atherosclerosis (James D, et al. Circulation. 103: 2922, 2001). [0003] In actual production, the stability of lutein ester to light, heat and acid is stronger than that of lutein. It is of great...

Problems solved by technology

However, due to the oil solubility of lutein esters limits its application range, the development of nano-scale cold water dispersible lutein ester microcapsule powder can not only directly apply lutein esters to water system food coloring, but also nano-scale Particle size can be better absorbed by the body
