Problems solved by technology

Therefore, although some scientists have tried, they have not entered the substantive stage. The reason is that the extraction and concentration process adopts the purification method of repeated filtration, and it is still impossible to remove the vegetable wax and vegetable fat that cannot improve the purity, so it reaches 80% purity. After that, it is difficult to break through the 80% limit of product purity.
In particular, the lack of high-purity ointment-type industrial products seriously restricts the improvement of the quality of products that use lutein as an additive to produce food, medicine, feed and other products that require lutein.

Embodiment Construction

[0015] Gather the purchased marigold petals and ferment them for 30 days at room temperature in a fermenter. Dry the fermented raw materials until the moisture content is not greater than 14%, sort and remove impurities, put them into a vacuum extractor, add organic solvents such as hexane or ethanol or acetone until the raw materials are completely submerged, and use 0.2MPa pressure at 50°C Under reflux extraction. Take out and filter to remove the slag, store it in a container and let it stand for 10 hours at -5°C-10°C, the vegetable wax will precipitate and condense, and the separation of vegetable fat will be completed. Then degrease in a centrifuge at 3000-4000 rpm, and the vegetable fat is separated. Then fine filter with a 0.45 μm microporous filter, then concentrate and dry at a pressure of 0.2 MPa and a temperature of 50° C. to obtain a finished lutein ointment with a lutein content of not less than 90 percent.

Abstract

Disclosed is a Lutein ointment extracted from marigold and method for extraction, which comprises collecting marigold petal, fermenting, drying, sorting, vacuum backflow extracting with organic solvents, finally carrying out filtering, dewaxing, degreasing and low temperate drying treatment.

Description

technical field [0001] The invention relates to a natural xanthophyll ointment extracted from plant marigold petals and a new method thereof. Background technique [0002] Marigolds contain carotene, a lutein structure that acts as a colorant. It has long been believed that the main form of lutein is the chloroplast in plants, and its main function is to absorb ultraviolet light. In fact, the content of lutein in green plants is very low, and it is produced by yellow flowers. After purification, the content of lutein is relatively low because the flowers contain symbiotic vegetable wax and vegetable fat. Therefore, although some scientists have tried, they have not entered the substantive stage. The reason is that the extraction and concentration process adopts the purification method of repeated filtration, and it is still impossible to remove the vegetable wax and vegetable fat that cannot improve the purity, so it reaches 80% purity. Finally, it is difficult to break th...
