Embodiment 1

[0011] Embodiment 1: Take 400 kilograms of duck eggs with red heart (the same below) produced by the female duck that eats Smilax, and add them to a 2000-liter stainless steel extraction kettle. Add 700 kilograms of mixed solvents again, mixed solvent is the mixed solvent of sherwood oil, acetone and ten polyglycerol monooleate (food grade) (the volume ratio of described sherwood oil, acetone and fatty alcohol polyoxyethylene ether is 5:1 : 0.02), stir, heat up to 40°C for 4 hours, cool down to 5°C, add 10 kg of diatomaceous earth, stir for 10 minutes, filter, wash the filter residue twice with 300 liters of petroleum ether and acetone mixed solvent, filtrate and The washing liquid is combined and collected in the distillation kettle. After the filtrate is concentrated and stirred for 1 hour, add 200 liters of 3% sodium chloride aqueous solution, then add 7 liters of polyethylene glycol (food grade) to wash for 1 hour, let it stand for half an hour, separate the water layer, a...

Embodiment 2

[0012] Embodiment 2: get 350 kilograms of duck's eggs with red heart, join in the 2000 liters of stainless steel extraction kettles. Add 700 kilograms of mixed solvents again, mixed solvent is the mixed solvent of sherwood oil, acetone and ten polyglycerol monooleate (food grade) (the volume ratio of described sherwood oil, acetone and fatty alcohol polyoxyethylene ether is 3:1 : 0.025), stir, heat up to 46°C for 5 hours, cool down to 0°C, add 10 kg of diatomaceous earth, stir for 10 minutes and filter, wash the filter residue twice with 300 liters of petroleum ether and acetone mixed solvent, filtrate and The washing liquid is combined and collected in the distillation kettle. After the filtrate is concentrated and stirred for 1 hour, add 200 liters of 3% sodium chloride aqueous solution, then add 5 liters of polyethylene glycol (food grade) to wash for 1 hour, let it stand for half an hour, separate the water layer, and then add deionized water , after stirring for 1 hour, ...

Embodiment 3

[0013] Embodiment 3: Get 300 kilograms of red heart duck eggs, join in the 2000 liters of stainless steel extraction kettles. Add 700 kilograms of mixed solvents again, mixed solvent is the mixed solvent of sherwood oil, acetone and ten polyglycerol monooleate (food grade) (the volume ratio of described sherwood oil, acetone and fatty alcohol polyoxyethylene ether is 9:1 : 0.03), stir, heat up to 49°C for 3 hours, cool down to 0°C, add 10 kg of diatomaceous earth, stir for 10 minutes, filter, wash the filter residue twice with 300 liters of petroleum ether and acetone mixed solvent, filtrate and The washing liquid is combined and collected in the distillation kettle. After the filtrate is concentrated and stirred for 1 hour, add 200 liters of 3% sodium chloride aqueous solution, then add 6 liters of polyethylene glycol (food grade) to wash for 1 hour, let it stand for half an hour, separate the water layer, and then add deionized water , after stirring for 1 hour, let stand f...

Abstract

The invention aims to provide a method for extracting carotenoid from duck eggs in order to solve the problem of high cost and complexity of existing production of carotenoid. By means of the method,organic substances beneficial to a human body such as carotenoids in egg yolk are protected against destruction, and the activity of the substances is preserved. Compared with a conventional method, the method for extracting carotenoid from duck eggs improves the efficacy by 3-5 times, increases the carotenoid content to 98%, and prevents the agglomeration of carotenoids.

Description

technical field [0001] The invention belongs to the field of biological materials and relates to a method for extracting carotenoids from duck eggs. Background technique [0002] Background technology: Carotenoids are a general term for a class of important natural pigments, which generally exist in yellow, orange-red or red pigments of animals, higher plants, fungi, and algae. Carotenoids are the main source of vitamin A in the body, and also have anti-oxidation, immune regulation, anti-cancer, and anti-aging effects. In today's society, people have higher and higher requirements for green food, and the direct extraction of carotenoids from natural raw materials is undoubtedly the best and most reliable method. Natural extraction of carotenoids has been extensively studied, but mainly limited to lycopene and B2 carotene. The existing extraction and purification methods are: solvent extraction, supercritical fluid extraction, distillation, membrane separation, chromatograp...
